What is a thesis and is it compulsory for a master's or PhD degree abroad?
A thesis is a long independent research document written under a faculty advisor and defended before experts. It is virtually always compulsory for a PhD abroad, but optional for many Masters programs, where you can choose a non-thesis coursework or capstone track instead of the research route.
A thesis is a comprehensive research paper that proves you have mastered a subject through independent study under a faculty advisor. Whether it is compulsory depends entirely on your degree level, and the terminology can even flip between regions, so it helps to know exactly what applies to your target program.
Thesis Requirement by Degree Level
| Degree | Is a Thesis Compulsory? |
|---|---|
| Master's thesis track | Yes if chosen; 1 to 2 years of research and a 40 to 100 page document, favoured if you aim for a PhD |
| Master's non-thesis track | No; common in MBA, MPH and MSc Finance, completed via coursework, exams or a capstone |
| PhD | Yes, virtually always; must contribute new, original knowledge |
| PhD by Publication | Alternative in parts of Europe and the UK; compile peer-reviewed papers instead of one book |
Terminology and Scope by Region
| Aspect | Detail |
|---|---|
| US and Canada | Thesis for Master's, dissertation for PhD |
| UK and Commonwealth | Terms are often reversed |
| Master's thesis scope | 40 to 100 pages, synthesises existing theory |
| PhD thesis scope | 3 to 5 plus years, 60,000 to 100,000 plus words of new knowledge |
My Advice
Let your career goal decide the track. If you want to move into corporate industry after your 2027 master's, a non-thesis coursework or capstone program will serve you better and finish faster. If academia or a future PhD is the plan, choose the thesis track deliberately so you build the research and writing skills that a doctoral program will demand.
