Earning a graduate degree helps advance your career by honing critical-thinking skills and deepening field-specific knowledge. For some professions, both a master’s and doctoral degree are necessary. In a graduate program, you're required to complete a major research and writing project, like a dissertation for a doctoral degree or a thesis for a master’s.

A dissertation typically explores a broader topic and involves more original research, making a significant contribution to the field. On the other hand, a thesis tends to focus on a more specific aspect of a topic and may rely more on existing research. However, it's important to understand the key differences and similarities between these two projects i.e. Thesis vs Dissertation.

Let’s get right into it!

What is Dissertation?

A dissertation is a thorough research project required for advanced degrees like a Ph.D. It entails delving deeply into a specific topic over several months or even years to contribute new insights to your field. This involves conducting a comprehensive literature review, detailing your research methods, presenting your findings, and discussing their implications. Successfully completing a dissertation demonstrates your ability to conduct independent research and advance knowledge in your academic discipline.

However, writing a dissertation follows a structured format, starting with an introduction outlining the research problem and objectives. The literature review summarizes existing research, while the methodology describes how the research was conducted. Results are presented and analyzed, often with tables or figures. The discussion interprets the results and suggests future research areas. It's a rigorous academic task, demanding dedication, critical thinking, and scholarly writing skills.

What is Thesis?

A thesis is a significant piece of academic writing where a student explores a specific topic, presents their viewpoint, and backs it up with evidence. Unlike a dissertation, which is mainly for doctoral degrees, a thesis is often required for undergraduate or master's degrees. It involves thorough research, critical thinking, and organizing ideas. A well-written thesis shows the student's ability to deeply engage with their subject, form a clear argument, and communicate effectively. It's a culmination of their academic journey, demonstrating their knowledge, skills, and growth in their field.

In addition to presenting an original argument, thesis writing involves synthesizing existing research and literature on the topic. This includes conducting a thorough literature review to identify gaps and formulating a research question or hypothesis. Data is collected through various methods and analyzed to draw conclusions. Adhering to academic conventions and guidelines is crucial for clarity and proper citation. A well-crafted thesis contributes new insights to the field and showcases the student's critical thinking and communication skills.

Core Differences Between a Thesis and a Dissertation

One of the main differences between both terms is: A thesis is typically completed at the undergraduate or master's level, while a dissertation is usually required for a doctoral degree. However, the core differences between a thesis and a dissertation lie in their scope, depth, and academic level:




On the basis of Scope

Typically focuses on a narrower scope and may explore a specific aspect or question within a broader topic. It aims to demonstrate the student's mastery of a particular subject area.

Generally has a broader scope, aiming to contribute original research or insights to the field. It often addresses a significant gap in knowledge or explores a complex issue in depth.

On the basis of Depth

While comprehensive, the depth of analysis in a thesis may vary depending on the academic level and program requirements. It usually involves a comprehensive review of existing literature and may include original research, but the depth of investigation may not be as extensive as in a dissertation.

Typically requires a deeper level of analysis and investigation. It involves conducting original research, which may include collecting and analyzing primary data, developing new methodologies, or proposing novel theories. The depth of a dissertation reflects the candidate's ability to engage critically with complex concepts and contribute meaningful insights to the field.

On the basis of Academic Level

Often associated with undergraduate or master's level programs. It serves as a capstone project that demonstrates the student's understanding of the subject matter and research skills acquired during their academic program.

Commonly required for doctoral degrees, such as Ph.D. or Ed.D. It represents the culmination of several years of advanced study and research, showcasing the candidate's ability to conduct independent scholarly inquiry and make original contributions to their discipline.

Overall, a thesis is a focused project for college or master's, while a dissertation is a big research project for Ph.D. It's like a journey from learning a lot about a topic to becoming an expert who finds new things.

Regional Variations in Thesis and Dissertation Requirements

Thesis and dissertation requirements can vary based on academic institutions and even regions. These variations might include differences in formatting, citation styles, page length, committee structures, and oral defence procedures. For example, universities in different countries may have specific guidelines for the structure and content of the thesis or dissertation. Additionally, cultural and disciplinary differences can influence expectations regarding originality, methodology, and the role of the advisor or supervisor. Therefore, it's essential for students to familiarize themselves with the specific requirements and expectations of their institution and academic program.

Dissertation vs. Thesis: Europe

In Europe, the difference between a thesis and a dissertation is still there. A doctoral thesis is a detailed study done to get a Ph.D. It's all about original research. On the other hand, a dissertation is just one part of a bigger research project for post-grad studies. The thesis has changed a bit over time. Now, it involves a lot of background research too. So, a thesis will have lots of citations and references to earlier work, but the main focus is still on the new stuff you find out.

Dissertation vs. Thesis: USA

In the United States, a thesis is different from a dissertation. A thesis is like a shorter version of a dissertation and is done to earn a Master's degree. In fields like science and engineering, a student does advanced coursework and works on a research project, but the focus isn't on original research like it is for a doctorate. Instead, it's more about gaining technical skills. For example, in engineering, many students stop at a Master's degree and don't go on to get a Ph.D. But in fields like Chemistry, getting a Master's degree isn't always necessary before starting a doctorate. Some people who start a Ph.D. program but don't finish end up getting a Master's degree by writing up their research so far.

Factors that vary country-wise:

  • Formatting and Structure: Different regions and institutions may have specific formatting guidelines for the layout, organization, and structure of the thesis or dissertation. This can include variations in title page format, chapter headings, citation styles, and reference list formatting.

  • Page Length: Expectations regarding the length of the thesis or dissertation may vary between regions and disciplines. Some institutions may have strict page length requirements, while others may focus more on the quality and depth of the content.

  • Committee Structures: The composition and role of the thesis or dissertation committee can vary, with differences in the number of committee members, their expertise, and their involvement in the research process.

  • Oral Defense Procedures: The process of defending the thesis or dissertation through an oral examination can differ between institutions and regions. This may include variations in the format of the defense, the duration of the presentation, and the types of questions asked by the examining committee.

  • Originality and Contribution: Expectations regarding the level of originality and contribution to the field may vary, with some regions placing greater emphasis on innovative research findings and others focusing more on the thoroughness of the literature review and methodology.

Thesis vs Dissertation: Difference in the Process

In the process of completing a thesis, students often follow a more structured and guided approach, working closely with advisors or supervisors who provide direction and feedback throughout the research process. These may involve summarizing existing knowledge and theories on a particular topic, with an emphasis on demonstrating mastery of the subject matter. On the other hand, dissertations typically require students to take a more independent and self-directed approach to research, often conducting original studies or experiments to contribute new insights to their field. Dissertations tend to be longer and more comprehensive in scope compared to theses, reflecting the depth and complexity of the research undertaken.

Here are a few more differences between thesis and dissertation based on their process:

  • Thesis often involves a more structured and guided research process, while dissertation on the other hand, typically requires more independent research and self-direction.

  • Thesis may focus on summarising existing knowledge and theories and dissertation emphasises original research and contribution to the field.

  • Thesis is generally shorter in length and scope. On the other hand, dissertations are usually longer and more comprehensive in scope.


To wrap up, while both thesis and dissertations are significant academic projects, they differ in their scope, depth, and the level of independence required. Thesis are commonly completed at the undergraduate or master's level and tend to be more structured, focusing on summarising existing knowledge. On the other hand, dissertations are typically undertaken for doctoral degrees and involve original research, contributing new insights to the field.
