Dissertation vs Thesis: Your 2024 Guide

If you’ve been thinking about going to graduate school, you may be familiar with the application requirements, rigorous academic schedule, and thesis or dissertation you’ll be expected to complete. So, what exactly is the difference between a thesis and a dissertation? While there are similarities, there’s a clear difference between the two. In our guide, we compare dissertation vs thesis. Discover more about both – and what you can expect during your graduate program. Let’s get started!

• Table of Contents

What Is a Thesis?

A thesis is an academic paper or project that’s completed towards the end of a master’s degree program . It is typically completed as the capstone project , meaning it’s the final project required for a student to graduate.

Students need to select a narrow, specific topic within – or relating to – their field of study. Once they’ve selected a topic, students must conduct an in-depth review of existing research on their chosen subjects. The next step is to formulate an academic argument, an assertion they’ll need to support or prove with said research.

Therefore, a thesis is akin to an in-depth research paper. It’s comprised of research that essentially proves what a student has learned during their program.

What Is a Typical Thesis Structure?

A thesis generally follows a rigid structure that’s decided by the program, department, or university. Here is an example of a thesis structure:

• The Title Page
• Summary of Thesis Abstract
• Table of Maps and Figures
• The Thesis Body (Sometimes divided into chapters)
• The Results or Conclusion

Who Needs to Complete a Thesis?

Most master’s degree programs require students to complete a thesis. While some undergraduate programs may also require a thesis, these are generally shorter and narrower in scope.

Some programs will also require a master’s student to defend their thesis in front of a panel or committee.

What Is a Dissertation?

What is “the PhD paper” called? Some people refer to it as a PhD thesis, but it’s most commonly known as a dissertation in the US. Dissertations are the capstone project required at the tail end of a PhD program . It is almost always required, except for a select few one-year PhD programs .

Much like a thesis, dissertations are also academic papers that aim to prove a student’s expertise – while adding to the current body of knowledge – in their field. Thus, a student must look at existing research and conduct their own research .

Basically, it’s the magnum opus of a doctoral journey in the United States. A dissertation isn’t just a long research paper; it’s a beast of a project. It demands extensive research, originality, and the ability to make a meaningful contribution to your chosen field. Think of it as a research odyssey guided by a seasoned mentor. Once you’ve conquered this scholarly quest and defended your findings, you’ll proudly emerge with your hard-earned doctoral degree, a testament to your dedication and scholarly prowess.

A dissertation typically comes after a PhD student completes their required courses and passes their qualifying exams. In some programs, the dissertation process is embedded into the coursework. In such cases, students receive a jump start on their work, allowing them to potentially finish their program earlier.

What Does a Dissertation Do?

PhD candidates must present a new theory or hypothesis. Alternatively, they must present their research to question (or disprove) the existing accepted theory on their chosen subject. Students may choose to tackle their topic from a new angle or take their research in a different direction.

Most programs will require students to defend their dissertations. During the defense, candidates must be able to justify the methodology of their research and the results and interpretation of their findings. Defenses are typically oral presentations in front of a dissertation committee , where the students are asked questions or presented with challenges.

Although the defense may seem daunting, PhD students work closely with their advisors to prepare for their dissertations. Students receive feedback and advice to guide their dissertations in their chosen direction.

What Is the Typical Dissertation Structure? 

Dissertations follow a rigid structure typically set by the program, department, or university. Here is an example format:

• The Acknowledgments Page
• The Abstract
• Introduction
• The Literature Review & Theoretical Framework
• The Methodology
• Findings/Results
• Discussions of the Findings, including analysis, interpretation, and applications
• The Conclusion
• List of References
• Any Appendices

What Is a Doctoral Thesis?

A doctoral thesis is a substantial piece of scholarly work that marks the pinnacle of a doctoral degree program, such as a PhD. Think of it as the academic grand finale. Its primary mission? To showcase the candidate’s mastery in their chosen field and their knack for delving deep into research.

In a nutshell, a doctoral thesis is a mammoth project that calls for originality. You’ve got to dig, investigate, gather data, crunch numbers, and present real data-supported findings. All this hard work usually happens under the watchful eye of a knowledgeable mentor. Once you’ve conquered this scholarly mountain and defended your thesis successfully, you’ll be proudly awarded your well-deserved doctoral degree. It’s the hallmark of your expertise and contribution to your field.

And how does a doctoral thesis differ from a dissertation? That’s mainly a geographic explanation. While they’re largely similar in scope and purpose, when comparing a doctoral thesis vs. a dissertation:

• A dissertation is the PhD capstone requirement in the US .
• A doctoral thesis is the PhD capstone requirement in Europe .

Dissertation vs. Thesis: The Similarities

In the master’s thesis vs dissertation discussion, there are plenty of similarities. Both are lengthy academic papers that require intense research and original writing. They’re also capstone projects which are completed at the tail end of their respective programs.

Students must work closely with their respective committees (e.g., faculty members, advisors, professionals) who provide feedback and guidance on their research, writing, and academic arguments. Both thesis and dissertation committees have a committee chair with whom the students work closely.

In some ways, the requirements for theses and dissertations are quite similar. They require a skillful defense of a student’s academic arguments. What’s more, both papers require critical thinking and good analytical reasoning, as well as in-depth expertise in the chosen field of study.

Students must also invest a significant amount of time into both projects while also being able to accept and action feedback on their work.

Dissertation vs. Thesis: The Differences

What are the differences between a PhD dissertation vs. thesis? The first and most distinct difference is the degree program requiring a PhD dissertation or thesis. A dissertation is typically the capstone project for a doctorate, while a thesis is the capstone project for a master’s degree program (or undergraduate program).

Candidates will have to defend their dissertation during an oral presentation in front of their committee. Only some master’s theses require this.

During a thesis, students typically conduct research by reviewing existing literature and knowledge on their chosen subject. During a dissertation, students must do their own research and prove their theory, concept, or hypothesis. They should also expect to develop a unique concept and defend it based on the practical and theoretical results achieved from their rigorous research.

Theses are also typically shorter (around 40 to 80 pages). Dissertations, however, are much longer (between 100 and 300 pages). Of course, the actual length of the paper may depend on the topic, program, department, or university.

Dissertations and Theses: US vs. Europe

Whether you’re in the US or Europe, dissertations and theses are similar. However, European requirements and conventions differ slightly:

Doctoral Thesis

To ensure your PhD graduation, a dissertation is generally required. Doctoral theses in Europe are much like a PhD dissertation in the US : You must complete your own research and add to the existing body of knowledge in your field.

Master’s Dissertation

It may seem odd to require a dissertation for master’s degree programs, but in Europe, this is exactly what you’ll need. A master’s dissertation is a broader post-graduate program research project , though it’s most typically required for master’s programs.

Frequently Asked Questions

Here are a few of the most common questions we hear about the meaning of thesis vs. dissertation.

Is a Thesis and a Dissertation the Same?

Yes and no. In some ways, a dissertation and a thesis are the same. For example, both require original writing, critical skills, analytical thinking, plenty of research, and lots of academic effort. However, a thesis is more commonly reserved for master’s – and some undergraduate – programs. Dissertations are generally required by PhD programs in the United States.

Additionally, a thesis typically calls for heavy research and compilation of existing knowledge and literature on a subject. A dissertation requires candidates to conduct their own research to prove their own theory, concept, or hypothesis – adding to the existing body of knowledge in their chosen field of study.

How Long Is a Thesis vs. a Dissertation?

One of the primary differences between thesis and dissertation papers is their length. While a thesis might be anywhere from 40 to 80 pages long, a dissertation can easily run from 100 to 300. It’s important to note that these numbers depend on the specific program and university.

Does a PhD Require a Thesis or a Dissertation?

It all depends on where you are! While a US-based PhD requires you to complete a dissertation, a thesis (or “doctoral thesis”) is more commonly required for PhD candidates in Europe. In the US, a thesis is more commonly reserved for master’s degree programs and occasionally undergraduate programs. In Europe, a “master’s dissertation” is typically required for the completion of a master’s degree.

So, there you have it: an in-depth comparison of the dissertation vs. thesis academic requirements. Now that you know the primary similarities and differences between the two, it might become easier to decide your academic path. Just remember, you may be able to find a master’s program without a thesis or a doctorate without a dissertation requirement if you prefer. Good luck!

Dissertation vs Thesis: The Differences that Matter

Updated: June 19, 2024

Published: April 26, 2020

As a graduate student, you will have many different types of challenging coursework and assignments. However, the biggest project that you’ll work on when earning your master’s or doctoral degree will be your thesis or dissertation . The differences between a dissertation vs thesis are plenty. That’s because each of these pieces of writing happen at different times in one’s educational journey.

Let’s break down what a dissertation and thesis are so that you have a strong handle on what’s expected. For both a thesis and a dissertation, there is an obvious fluency and understanding of the subject one studies.

Let’s take a look at their similarities and differences.

What is a dissertation.

When you enter a doctoral program to earn a PhD, you will learn a lot about how to conduct your own research. At the culmination of your degree program, you’ll produce a dissertation.

A dissertation is a lengthy piece of written work that includes original research or expanded research on a new or existing topic. As the doctoral student, you get to choose what you want to explore and write about within your field of study.

What is a Thesis?

A thesis is also a scholarly piece of writing, but it is for those who are graduating from a master’s program. A thesis allows students to showcase their knowledge and expertise within the subject matter they have been studying.

Main Differences Between a Thesis vs. Dissertation

The biggest difference between a thesis and a dissertation is that a thesis is based on existing research.

On the other hand, a dissertation will more than likely require the doctoral student to conduct their own research and then perform analysis. The other big difference is that a thesis is for master’s students and the dissertation is for PhD students.

Structural Differences Between a Thesis and a Dissertation

Structurally, the two pieces of written analysis have many differences.

• A thesis is at least 100 pages in length
• A dissertation is 2-3x that in length
• A thesis expands upon and analyzes existing research
• A dissertation’s content is mostly attributed to the student as the author

Research Content and Oral Presentation

Once completed, some programs require students to orally present their thesis and dissertation to a panel of faculty members.

Typically, a dissertation oral presentation can take several hours. On the other hand, a thesis only takes about an hour to present and answer questions.

Let’s look at how the two scholarly works are similar and different:

Similarities:

• Each is considered a final project and required to graduate
• Both require immense understanding of the material
• Written skills are key to complete both
• Neither can be plagiarized
• Both are used to defend an argument
• Both require analytical skills
• You will have to draft, rewrite, and edit both pieces of writing
• For both, it is useful to have another person look over before submission
• Both papers are given deadlines

Differences:

• A dissertation is longer than a thesis
• A dissertation requires new research
• A dissertation requires a hypothesis that is then proven
• A thesis chooses a stance on an existing idea and defends it with analysis
• A dissertation has a longer oral presentation component

The Differences in Context: Location Matters

The united states.

In the US, everything that was previously listed is how schools differentiate between a thesis and a dissertation. A thesis is performed by master’s students, and a dissertation is written by PhD candidates.

In Europe, the distinction between a thesis and dissertation becomes a little more cloudy. That’s because PhD programs may require a doctoral thesis to graduate. Then, as a part of a broader post-graduate research project, students may complete a dissertation.

The purpose behind written research.

Each piece of writing is an opportunity for a student to demonstrate his or her ability to think critically, express their opinions in writing, and present their findings in front of their department.

Graduate degrees take a lot of time, energy, and hard work to complete. When it comes to writing such lengthy and informative pieces, there is a lot of time management that is involved. The purpose of both a thesis and a dissertation are written proof that you understand and have mastered the subject matter of your degree.

Degree Types

A doctoral degree, or PhD, is the highest degree that one can earn. In most cases, students follow the following path to achieve this level of education: Earn a bachelor’s degree, then a master’s, and then a PhD. While not every job title requires this deep educational knowledge, the salaries that come along with each level of higher education increase accordingly.

Earning Your Degree

Whether you are currently a prospective student considering earning your higher education degree or a student enrolled in a master’s or doctoral program, you know the benefits of education.

However, for some, earning a traditional degree on-campus doesn’t make sense. This could be because of the financial challenges, familial obligations, accessibility, or any other number of reasons.

For students who are seeking their higher education degrees but need a flexible, affordable, and quality alternative to traditional college, take a look at the programs that the University of the People has to offer.

University of the People is an entirely online, US accredited and tuition-free institution dedicated to higher education. You can earn your Master’s in Business Administration or your Master’s in Education . Not to mention, there are a handful of associate’s and bachelor’s degree programs to choose from as well.

The Bottom Line

Regardless of where and when you earn your master’s or doctoral degree, you will likely have to complete a thesis or dissertation. The main difference between a thesis and dissertation is the level at which you complete them. A thesis is for a master’s degree, and a dissertation is for a doctoral degree.

Don’t be overwhelmed by the prospect of having to research and write so much. Your educational journey has prepared you with the right time management skills and writing skills to make this feat achievable!

Thesis vs. Dissertation: What’s the difference?

Thesis and dissertation are extensive research papers that differ in terms of their requirements, length, and purpose, with the former being associated with a master's degree and the latter with a doctoral degree, but are often used interchangeably.

Updated on September 15, 2023

A thesis and a dissertation are both extensive research papers, and both require literature searches and novel findings, but the two differ in various ways. Their definitions also differ across regions. Typically, in North America, a thesis is required for the completion of a master’s degree, while a dissertation is required for the completion of a doctoral degree. The former is long, while the latter is longer and more intensive.

Despite these differences, the two terms are often used interchangeably, especially among those who haven’t completed one or the other. Here, we’ll compare the components, length, and purpose of these two academic documents to clearly understand the differences between these important papers in the life of a graduate student.

What’s a thesis?

The term “thesis” explained here is generally consistent with how the word is used in North America to describe this substantive research paper.

A thesis is an extended argument (PDF). It is a research-based document that displays the student’s/author’s knowledge and understanding of a specific subject within their field of study. It generally presents findings on a particular topic. 

See this and this (PDFs) for examples. These superb master’s theses from Canada will give you an idea of the size and format of these papers.

Who would write a thesis?

You generally write a thesis if you’re undertaking a research-oriented master's degree program (as opposed to a practical program, which may require a capstone, internship, exam, etc.). 

The thesis is the essential part of a program’s research component, demonstrating the student's ability to critically analyze the literature and complete independent research. The process of writing a thesis involves exploring a specific research question, conducting a comprehensive literature review, collecting and analyzing data, and presenting findings in a structured and cohesive way.

A thesis' specific requirements and expectations differ depending on the academic institution, department, and program.

Components of a thesis

A thesis is typically presented in chapters. How many chapters will vary, but a common structure is:

• Introduction: Presents the research topic, purpose, and objectives, setting the context for the work.
• Literature review: Comprehensive survey of existing scholarly material related to the research topic, highlighting key theories and findings.
• Methodology: Describes the methods, procedures, and tools used in doing the research.
• Research: The actual performing of the study, collecting, and analyzing data relevant to the research question.
• Findings and conclusions: Gives the results obtained and explains their significance in relation to the research question.
• Limitations and future research: Outlines the study’s shortcomings and suggests potential areas for future investigation.

Within that structure, and in addition to those parts, a thesis may also include: 

• Cover page: Contains the thesis title, author's name, institution, department, date, and other relevant information
• Abstract : A brief summary of the thesis, highlighting the research objectives, methods, key findings, and conclusions.
• Certificates of own work
• Certificate of readiness to be included in the library
• Certificate that the research has not been presented to another university
• Acknowledgments
• Table of contents: List of the main sections, subsections, and corresponding page numbers.
• Index of figures and tables
• References: A comprehensive list of all the sources cited in the thesis, following a specific citation style (e.g., APA, MLA).
• Appendices (optional): Additional materials include:
• Abbreviations and/or acronyms used
• Questionnaire or interview schedule/s (if used)
• Data acquired in the form of transcripts or numeric tables
• Research protocol
• Ethics protocol

What’s a dissertation?

This is also viewed from a North American perspective, where a dissertation is usually the main research work toward completing a research-based doctoral program.

A dissertation is a comprehensive and in-depth research project completed as part of the requirements for a doctoral degree. It’s a substantial piece of original work that contributes new knowledge to a specific field of study.  Naturally, when it’s completed as the major requirement for earning a PhD, it’s longer, more detailed, and the expectations are higher.

Dissertations themselves can add to the literature in the field. For this reason, some students choose to publish them and have them indexed. The research and the data acquired while working on a dissertation can potentially lead to more publications and help define the researcher’s growing area of expertise.

See this and this (PDFs)  top-ranking dissertation on ProQuest for good examples.

Who would write a dissertation?

Completion and defense of a dissertation is a standard requirement for doctoral students to earn a PhD or another doctorate such as an EdD or DM. But some specialized degrees, such as a PsyD (Doctor of Psychology), JD (Juris Doctor) or DPT (Doctor of Physical Therapy) may have practice-based requirements in place of a research project, as these courses of study are geared more toward practical application.

Components of a dissertation

A dissertation’s components are generally the same as those of a thesis. You can look at the list above for a thesis to see what typically goes into a dissertation. But, if compared with a master’s thesis, most aspects are longer and more rigorous.

The word count requirements for theses can vary significantly, but doctoral dissertations often range 40,000–80,000 words or, per Harvard , 100–300 pages.

Differences between a thesis and a dissertation

As already touched on, the key differences are in where the two documents are used, length, and rigor. There are also regional differences.

A thesis typically demonstrates a master’s degree program student's grasp and presentation of a specific subject in their field of study. It normally involves a literature review, data analysis, and original research, but it is usually shorter and less comprehensive than a dissertation. The standards for rigor and novelty may also be lower.

A dissertation requires more extensive research, original contributions to the field, and a deeper exploration of the research topic. A dissertation is typically the output associated with a doctoral degree program.

The main differences in structure between a thesis and a dissertation are in the scope and complexity.

The word count requirement for theses and dissertations can vary depending on the institution and program.

A thesis is usually 20,000–40,000 words. However, there have been cases of mathematics dissertations that were only a few pages long!

Doctoral dissertations may range 60,000 to upward of 100,000 words, and exceed 100 pages. Many universities, however, seek around 80,000 words.

Oversight and process

A thesis may simply be submitted to the student's instructor, though rigorous thesis programs require a committee and defense. A dissertation will nearly always require the student to choose a chair, a committee, and then go through a more rigorous defense and revision (if necessary).

• Committee: Master's thesis committees usually have fewer members (typically 2–3) than doctoral dissertation committees (often 4–5, or even more).
• Guidance: Master's students often receive more detailed direction from advisers than doctoral students, who are expected to work more independently.
• Review: Dissertation reviews are typically more rigorous, often involving external reviewers, while thesis reviews are usually internal.
• Defense: A dissertation defense is generally more intense and formal, as it often involves a presentation to the wider academic community, while a thesis defense might be more confined and informal.
• Revision: The revision process for a doctoral dissertation is typically more extensive, given the larger scope of the project and higher stakes involved, compared with those for a master's thesis.

Regional differences

The terms' use varies among (and even within) countries. Here are some general regional differences:

In the United Kingdom, a thesis is commonly associated with both master's and doctoral degree programs. For example, the University College London  refers to a thesis for EngD, MPhil, MD(Res), and PhD degrees. At the University of Nottingham , a dissertation is written for a research master’s degree.

In Australia and New Zealand , “thesis” is generally used to refer to a substantial research project completed for a higher degree, though not limited to a master’s (you’ll find ample references to a “PhD thesis”).

In Latin American countries,  the thesis is commonly used to refer to both master's and doctoral research projects.

Closing thoughts

Both theses and dissertations are necessary documents for students in graduate programs. Despite the differences in expectations, and even in definitions of these papers, the student-author must do a diligent and rigorous job to earn their degree.

Dissertation Vs Thesis: How Are They Different

Dissertation vs thesis! What are you writing? 

Table of Contents

Many graduate students from universities in Canada often get confused and mix both terms. While these terms are often used interchangeably, they carry distinct meanings and purposes in academia. Read this blog to fully understand the difference between a thesis and a dissertation. 

What Is A Dissertation

A dissertation is a substantial piece of academic writing typically required to complete a doctoral degree (such as a Ph.D.). It represents an original and significant contribution to the field of study and is usually the culmination of several years of research and study.

What Is A Thesis

A thesis is a scholarly piece of writing, usually at the master’s or undergraduate level, that presents an original research question, methodology, and findings. It represents the culmination of a student’s academic work and demonstrates their ability to contribute to the field of study.

The Evolution Of Dissertation Vs Thesis

The history of the thesis and dissertation dates back several centuries, and the evolution of these academic documents reflects changes in scholarly practices, educational systems, and the expectations of advanced degree programs. 

Medieval Origins

The concept of a scholarly thesis has roots in medieval universities. In the 12th and 13th centuries, institutions like the University of Paris introduced the practice of disputations, where students defended their theses in a public forum. These early theses were often theological or philosophical in nature.

Renaissance And Early Modern Period

During the Renaissance, the practice of defending theses continued to evolve. The 16th and 17th centuries saw an increasing emphasis on empirical observation and scientific inquiry. The thesis became more diverse, covering topics in natural philosophy, mathematics, and other emerging disciplines.

18th And 19th Centuries

The 18th century marked the formalization of the thesis as a requirement for academic degrees. Universities started to mandate the submission of a written document along with the oral defence. This practice became more standardized in the 19th century as universities across Europe and North America adopted similar academic norms.

Evolution Of The Dissertation

The term “dissertation” has its roots in the Latin word “dissertatio,” meaning “discussion.” Dissertations, as we understand them today, emerged in the 19th century, primarily in German universities. Doctoral candidates were required to produce substantial research demonstrating their ability to contribute original knowledge to their field.

20th Century

The 20th century saw a global expansion of higher education and an increase in the number of doctoral programs. The thesis and dissertation became integral components of graduate education worldwide. The structure, format (eg, APA or MLA ), and expectations for these documents varied among disciplines and institutions.

Electronic Theses And Dissertations (ETDs)

With the advent of digital technology in the late 20th century, there was a shift toward electronic submission of theses and dissertations. This made research papers more accessible and facilitated the dissemination of knowledge. Many universities now require the submission of ETDs.

Contemporary Trends In Dissertation Vs Thesis

In the 21st century, the thesis and dissertation continue to evolve. Educational institutions are adapting to new forms of scholarship , interdisciplinary research, and varied modes of dissemination. The focus is often on producing high-quality, original research that contributes significantly to the academic community.

What Is The Difference Between A Dissertation And A Thesis 

Thesis vs dissertation: length and depth.

One of the key differences between a thesis vs dissertation lies in their length and depth of research:

Theses are typically shorter in length, ranging from 50 to 100 pages, depending on the institution and program requirements. The research conducted for a thesis is expected to contribute to the existing literature but may not need to be as exhaustive as that of a dissertation.

Dissertation

Dissertations, being the pinnacle of doctoral research, are substantially longer, often exceeding 100 pages and sometimes reaching several hundred pages. Doctoral candidates are expected to delve deeply into their chosen topic, conducting extensive research and offering a unique contribution to the academic community.

Dissertation Vs Thesis: Scope And Purpose

Another significant distinction between a dissertation vs thesis is the scope and purpose of the research:

The primary goal of a thesis is to demonstrate a student’s understanding of the subject and their ability to conduct independent research within a defined scope. A thesis is often more focused and may be an exploration or analysis of a specific aspect of a broader topic. For example, a finance thesis could be about any topic within the subject. 

Dissertations, being doctoral-level projects, have a broader scope. Doctoral candidates are expected to make an original and substantial contribution to the field, advancing existing knowledge and addressing gaps in the current literature. Dissertations often involve more extensive data collection, analysis, and synthesis of information.

The research paper we write have:

• Precision and Clarity
• Zero Plagiarism
• High-level Encryption
• Authentic Sources

Dissertation Vs Thesis: The Similarities

While there are distinct differences between a thesis vs dissertation, they also share several similarities, reflecting their common purpose within academic research papers . Here are some key similarities between a dissertation and a thesis.

Research Component

Both dissertations and theses involve original research and scholarly inquiry. Students are expected to engage in a systematic investigation of a chosen topic, demonstrate a deep understanding of existing literature, and contribute new knowledge or insights to their field.

Academic Rigour

Both documents adhere to high standards of academic rigour and integrity. They require meticulous attention to detail, adherence to citation and referencing styles, and a commitment to intellectual honesty.

Formal Structure

Dissertations and theses typically follow a formal structure, including elements such as a thesis statement , an introduction, a literature review, methodology, results, a discussion, and a conclusion. This structured format ensures a comprehensive presentation of the research.

Faculty Guidance

In both cases, students work closely with faculty advisors or mentors throughout the research process. Advisors guide research design, literature review, data analysis, and other aspects of the project.

Oral Defense

A commonality between dissertations and theses is the requirement for an oral defence. In many academic institutions, students must defend their research findings before a committee of faculty members. This defence allows students to articulate their research methods, results, and conclusions, while also responding to questions and critiques.

Degree Requirement

Both a thesis and a dissertation serve as a crucial component for the completion of an academic degree. Thesis is typically associated with master’s programs, while dissertations are a requirement for doctoral degrees. In both cases, successfully completing the research project is essential for obtaining the respective degrees.

Contribution To Knowledge

Whether a thesis or a dissertation, the primary goal is to contribute to the existing body of knowledge in a particular field. Both documents aim to advance understanding, address gaps in the literature, and offer meaningful insights that can inform future research.

Literature Review

A comprehensive literature review is a common element in both dissertations and theses. This section provides context for the research by summarizing and critiquing relevant scholarly works, helping establish the rationale and significance of the study.

Frequently Asked Questions

What is the difference between a dissertation and a thesis.

A thesis is a shorter, master’s-level research document demonstrating mastery of a subject. A dissertation, typically for a doctoral degree, is longer and requires a more extensive, original contribution to the field.

What is the difference between a master thesis and dissertation?

What Is the Difference Between a Dissertation and a Thesis?

One of the most common areas of confusion in the world of academia is the difference between a dissertation and a thesis . Understanding the distinctions, as well as the similarities between these two types of research documents is important for students embarking on their academic journey. To assist you in this journey, the academic experts at Accuracy have developed an essential guide that delves into the key differences, overlaps, purposes, and requirements of a thesis vs. dissertation.

Definitions and Purposes

A thesis and a dissertation are both comprehensive research projects that are required for completing graduate degrees. However, they serve different purposes and are used at different stages of academic training.

A thesis is typically required for a master’s degree and demonstrates the student’s ability to analyse and interpret existing research on a specific topic. It usually consists of far less in-depth research and analysis than a dissertation. On the other hand, a dissertation is required for a doctoral degree and involves original research that contributes new knowledge to the field. It is a much more extensive and detailed academic research document as compared to a thesis.

Key Differences: Thesis vs Dissertation

Length and depth of research.

• Thesis: It generally ranges from 50 to 100 pages, depending on the field of study and institution. It involves a literature review and thorough analysis of existing research to support a particular argument or hypothesis.
• Dissertation: It can range from 100 to over 300 pages, involving comprehensive original research including data collection, analysis, and presenting new findings that contribute to the academic field. It is a far more substantial body of work compared to a thesis.

Academic Level

• Thesis: It is typically written by students pursuing a master’s degree.
• Dissertation: It is mandatory for students completing a doctoral (PhD) program.

Locational and Institutional Variations

The terms ‘ thesis ’ and ‘ dissertation ’ can have different meanings depending on the country and institution. For instance, in the United States, a thesis is associated with a master’s degree and a dissertation with a doctoral degree. In contrast, the terms can be used interchangeably or even reversed in some European countries where a doctoral thesis is required for completing a PhD program while master’s programs are completed through the submission of a dissertation. 

In many academic institutions, each department will have its guidelines for the usage of the terms ‘thesis’ and ‘dissertation’ and it is advisable to refer to the individual course handbook for the relevant information. 

Structure and Components

A thesis and dissertation will have similar structural components, designed to present research findings in a scholarly and coherent way. However, the length, depth of research and scope of analysis will vary for each section.

When it comes to thesis vs. dissertation, there are many common components in the overall structure. They both typically start with an abstract and acknowledgements, followed by a table of contents. The main body begins with an introduction that sets the stage for the research, explaining its objectives and significance. This is followed by a literature review that surveys existing work related to the topic, and a methodology section detailing the research design and methods used for data collection and analysis. 

Thereafter, the results section in these documents interprets the results and links them back to the research questions and existing literature. The conclusion summarizes the key findings, highlights the research contributions, and suggests directions for future research. Finally, the document includes references, listing all sources cited, and appendices, providing supplementary material such as raw data or additional explanations. This structured approach ensures clarity and allows readers to follow the research process and findings logically.

Is a dissertation harder than a thesis?

Generally, a dissertation is considered to be more challenging than a thesis due to its length, depth, and the requirement for original research. Dissertations involve a higher level of complexity, including formulating unique research questions, conducting extensive primary research, and providing in-depth analysis and discussion of findings. Theses, while still demanding, typically focus more on analysing existing research rather than producing new data. As a result, writing a dissertation takes far more time and effort than a thesis.

The Role of Editing and Proofreading Services

Whether you are writing a thesis or a dissertation, the quality of your work can be significantly enhanced through professional editing services . Here’s how they can help:

• Dissertation Editing Services : These services focus on improving the structure, clarity and coherence of your dissertation. Editors improve the overall flow and ensure that the arguments are well-presented and supported by evidence.
• Dissertation Proofreading Services : Proofreading services focus on correcting grammatical errors, typos, and formatting issues, ensuring that the document is polished and professional.
• Thesis Editing Services : Similar to dissertation editing , thesis editing involves refining the content, structure, and clarity of your thesis. Editors help ensure that your arguments are logically presented and that the research is thoroughly analysed.
• Thesis Proofreading Services : This ensures that your thesis is free from spelling errors, grammatical issues and formatting inconsistencies. By meticulously reviewing your thesis, proofreaders help you present your research clearly and accurately, increasing the likelihood of acceptance by academic committees.

Understanding the differences between a thesis and a dissertation is crucial for students preparing for their academic research projects. Both require rigorous research, analysis, and writing, but they serve different purposes and are required at different stages of academic study.

As a graduate student, you've probably heard the terms "dissertation" and "thesis" being used interchangeably. This creates a lot of confusion among students about what they really mean. 

While they might seem like synonyms, there are actually significant differences between the two. Understanding these differences is important, as it can affect the type of research you conduct. 

This blog will explain the key differences between dissertations and theses. So continue reading to clear up any confusion you may have. 

On This Page On This Page -->

Thesis and Dissertations - Definitions

Before we go into the differences between the two, let's start by defining what we mean by "thesis" and "dissertation."

What is a Dissertation? 

A dissertation is a piece of original research that is conducted as a requirement for a doctoral degree . It is also known as a doctoral dissertation.

The purpose of a dissertation is to contribute new knowledge to the academic community by conducting research in a particular field of study. The research is conducted independently by the candidate and is presented in the form of a written report.

Moreover, the research presented in a dissertation is expected to be original, thorough, and well-documented. It is often published as a monograph or a series of articles in scholarly journals.

Research Contribution and Process:

In a dissertation, students may present a new theory or hypothesis , or challenge existing theories in their field. The process traditionally follows doctoral coursework and qualifying exams, culminating in the research and composition of the dissertation. 

However, exceptions exist, with some universities integrating the dissertation process into coursework. This allows students to initiate their research early, potentially expediting their graduation. Such integration offers a unique approach, allowing students to advance their research and fulfill course requirements concurrently.

Writing a good dissertation is an essential skill for Ph.D. students. Learn more about dissertation writing with our complete guide.

What is a Thesis?

A thesis is also a compulsory research assignment that presents the results of original research conducted by graduate students. A thesis is typically required as partial fulfillment of a master's degree program.

The purpose of a thesis is to demonstrate the student's mastery of a particular subject and their ability to conduct research. A thesis is heavily reliant on literature reviews and uses established research to reach independent conclusions.

Definitions Change Based on Your Location

Both the thesis and dissertation are final projects necessary to earn a degree. However, the definitions change based on where you are. The above definitions are true for the US, while it's totally opposite for Europe.

• In the US, a dissertation is written for a Ph.D. program. While a thesis is written for a master's or graduate.
• Meanwhile, in Europe, a dissertation is done during a master's or graduate degree. While a thesis is written as a part of a Ph.D.

Now that you know the basic concept, read on to learn more about their differences and similarities.

Differences between Thesis and Dissertations 

The table below summarizes the major dissertation vs thesis difference:

Let's look at each difference in detail.

Degree Requirement

Thesis and dissertations are required for different types of degrees after specific years of studying. 

A dissertation is required for completing a doctoral program, while a thesis is required to complete your graduate school studies. 

In Europe, it's the opposite. You need to write a thesis as a doctoral student and a dissertation for graduate studies.

Thesis Vs Dissertation Length

One of the most obvious differences between dissertations and theses is their length. 

Dissertations are typically longer than theses, often ranging from 100 to 500 pages. Meanwhile, theses are usually shorter, ranging from 30 to 100 pages. 

This is because dissertations are more comprehensive and require more extensive research than theses.

Another key difference between dissertations and theses is the goal or objective. 

The objective of a dissertation is to contribute new knowledge to the academic community. In contrast, theses often focus on synthesizing existing research or analyzing a specific aspect of a topic. 

The purpose of a dissertation is to demonstrate the student's ability to conduct independent research and contribute new knowledge in the field. 

In contrast, the purpose of a thesis is to demonstrate the student's mastery of a particular subject. That is why it is often more focused and narrower in scope than a dissertation.

Presentation

Another significant difference between dissertations and theses is how they are presented to the academic community.

While both require a written draft, a dissertation includes a defense in front of a scholarly committee. During the dissertation defense, the student presents their research to the committee, followed by a period of questioning and discussion. 

The committee may ask questions about the research methodology, results, and conclusions and may challenge the student's ideas and arguments.

Meanwhile, the thesis may only contain a simple presentation along with a question-and-answer session with the faculty members. It varies depending on the program and institution.

Here's a short video that briefly describes the differences between a thesis and a dissertation:

Differences Between Thesis and Dissertation Across Academic Levels

Students frequently experience confusion when attempting to discern the similarities and differences between theses and dissertations at various academic levels. In this section, we will explore how undergraduate, master's, and PhD theses and dissertations differ.

Dissertation Vs Thesis Undergraduate

At the undergraduate level, a term thesis is a focused independent study demonstrating a student's ability within a specific topic. 

On the other hand, a dissertation suggests a broader research scope, allowing for a more expansive exploration of academic inquiries. The difference lies in the depth and breadth of the research undertaken. But they are the requirement to graduate.

Master's Dissertation Vs Thesis

A master's thesis showcases a student's mastery of a subject through a focused review and synthesis of existing literature.  On the other hand, a master's dissertation involves original research, contributing new knowledge to the academic field. 

The thesis demonstrates understanding, while the dissertation emphasizes the creation of new knowledge.

PhD Thesis Or Dissertation

The main difference between a PhD thesis and a dissertation lies in the level of original contribution to the academic field. A PhD dissertation, crucial for earning PhD degrees, involves extensive research, data collection, and the development of groundbreaking theories.

In contrast, a PhD thesis, while still requiring original research, may focus more on demonstrating the candidate's mastery of a subject through structured analysis. The distinction is in the depth of original contribution, with a dissertation aiming for a substantial advancement in the field.

Similarities Between Dissertation and Thesis

The dissertation and thesis are also similar in some ways. Here are some similarities between thesis and dissertation:

Both the dissertation and thesis contain the following components of research:

• Introduction
• Literature Review
• Research methods/material
• Bibliography

However, the length and depth of each section may vary depending on the specific requirements and scope of the research.

Supervision

Students conduct their thesis or dissertation under the guidance and supervision of an academic scholar. The Supervisor (or Advisor) helps and guides them throughout the process of completing their research. 

The supervisor is also responsible for ensuring that research is conducted in an ethical and academically sound manner.

Other Similarities 

Apart from the structure and academic procedure, there are also other similarities, such as:

• They are both long-form research assignments that are required to earn a degree.
• Both require students to demonstrate their ability to write and communicate their research effectively, using appropriate academic conventions.
• Both require a specific and well-defined hypothesis or research questions.
• Both require students to demonstrate a deep knowledge of their field.
• Both require students to analyze data and draw conclusions based on their findings.
• Both require students to demonstrate their ability to think critically and independently.

Thesis vs. Dissertation: Understanding the Differences

A thesis and a dissertation are often used interchangeably, causing confusion among students and academics alike. While they share some similarities, they are distinct in purpose, scope, and requirements. Understanding these differences is crucial for graduate students embarking on their academic journey. In this article, we delve into the world of thesis and dissertation, shedding light on what sets them apart and helping you navigate these essential components of advanced academic research.

Thesis: The Master's Magnum Opus

In the realm of academia, a thesis is often referred to as the master's magnum opus, representing the pinnacle of a student's academic journey at the master's level. It is a significant undertaking that requires dedication, research acumen, and a commitment to scholarly excellence. Here, we explore the key characteristics and elements that define a thesis:

Academic Level: A thesis is a hallmark of master's degree programs. It serves as the culmination of a student's graduate studies, demonstrating their ability to engage critically with their field of study and contribute meaningfully to it. Unlike undergraduate projects, a thesis delves deeper into the subject matter and requires a higher level of analysis and synthesis.

Purpose: The primary purpose of a thesis is to contribute to the existing body of knowledge within a specific field or discipline. It goes beyond mere regurgitation of facts and concepts; it involves original research or a novel approach to addressing a research question or hypothesis. In essence, a thesis is a scholarly endeavor that aims to add value to the academic conversation.

Scope: Theses typically have a narrower scope compared to their doctoral counterparts, dissertations. While they explore complex topics, they often focus on a specific aspect or dimension within a broader field. This focused approach allows students to delve deeply into their chosen subject matter and demonstrate expertise in that area.

Length: Theses vary in length depending on the institution, program, and field of study. However, they are generally shorter than dissertations. A typical master's thesis can range from 50 to 100 pages. This concise format necessitates precision and clarity in presenting research findings and arguments.

Committee Evaluation: A key aspect of the thesis process is the evaluation by a committee of professors or advisors. This committee plays a pivotal role in guiding the student's research, offering feedback, and assessing the final product. Their expertise ensures that the thesis meets academic standards and contributes meaningfully to the field.

Research and Methodology: Research is at the heart of any thesis. Students engage in systematic inquiry, which may involve data collection, experimentation, surveys, literature analysis, or a combination of research methods. The methodology chosen should align with the research question and contribute to the overall quality of the thesis.

Scholarly Writing: A thesis demands scholarly writing of the highest caliber. Students are expected to adhere to academic writing conventions, including proper citation, referencing, and adherence to a specific style guide (e.g., APA, MLA). Clarity, coherence, and a formal tone are essential elements of thesis writing.

Originality: Perhaps the most crucial aspect of a thesis is its contribution to the field's body of knowledge. It must offer fresh insights, perspectives, or solutions to existing challenges. Originality is the hallmark of a well-executed thesis, distinguishing it from undergraduate assignments.

• Interest and Expertise : Choose a topic that aligns with your academic interests and expertise, as both require significant time and effort.

Understanding the differences between a dissertation and a thesis is essential for students as they plan their academic careers. While both involve substantial research and writing, they differ in scope, purpose, and academic level. A dissertation is generally more extensive, aiming to contribute original knowledge to a field and fulfill doctoral requirements. A thesis is shorter and focuses on synthesizing existing knowledge, typically for a master’s degree. By choosing the right topic and approach, students can make meaningful contributions to their fields through these research projects.
