If you plan to pursue an advanced degree, you may be wondering about the differences between dissertation vs. thesis projects.

Most candidates in master’s or PhD programs are required to complete a final project in the form of a thesis or dissertation before graduating.

Because both a master’s thesis and a doctoral dissertation consist of in-depth research, analysis, and writing, some people use the terms interchangeably. They are separate assignments, though, that are completed at different stages in a student’s academic journey.

What’s the Difference Between a Dissertation vs. Thesis?

Students enrolled in masters degree programs typically write a thesis, whereas doctoral students complete a dissertation.

Although these projects are both research-based and are usually required for graduation, they have different lengths, requirements, and timeframes. Knowing how to distinguish between them is vital for anyone hoping to attend graduate school.

What Is a Thesis?

A thesis is a scholarly paper that many students write before completing their master’s programs. Most graduate schools require students to submit a thesis that reflects the breadth and depth of their knowledge of the field and demonstrates their advanced research skills.

To create a thesis, students begin by selecting a topic of interest and conducting extensive research in that area. That information serves as the basis for a lengthy paper that describes the student’s position on the subject and presents evidence proving their assertion. Although it’s not common, some undergraduate schools also require students to write a short thesis.

What Is a Dissertation?

A dissertation is a doctoral-level project that is a standard feature of PhD programs. When completing a dissertation, a student will conduct original or expanded research that can contribute to their field and solidify their status as a scholar.

So, what’s a dissertation and how long does it take to write one? Dissertations are often hundreds of pages in length and are completed over several years. They reflect that a student not only understands the current state of the field but also has a unique approach to the subject matter. After writing a dissertation, a student must defend it to a committee and faculty chair, who determine whether it is acceptable.

A number of universities now offer doctorate programs without dissertations but have a capstone project for completion. Common programs are DBA degrees or doctoral programs in education with no dissertation online or on campus.

Differences Between a Dissertation vs. Thesis

A dissertation and thesis are distinct in important ways, including:

The difference between dissertation and thesis projects depends on where you’re studying. For instance, in the United Kingdom, master’s students complete a dissertation, and PhD students write a doctoral thesis.

Similarities Between a Thesis vs. Dissertation

Much like the similarity between a dissertation vs. capstone, a thesis is usually accomplished as a partial requirement for an academic degree. A thesis and a dissertation usually share these common features:

If you intend to complete a doctoral dissertation, you may have the opportunity to expand on the research from your master’s thesis or select a new area of interest.

Theses and Dissertations

There may be a difference between a thesis and a dissertation in terms of when students complete them, how long they are, and what type of research they involve, but they are both beneficial academically and professionally.

These projects provide students with an opportunity to gain expertise in their fields and prepare for their careers. Graduates also sometimes publish their work as journal articles or books. Having a record of publications may strengthen your candidacy for future positions. Writing a dissertation or thesis is challenging, but it can be a valuable experience.
