What Reviewers Look For in the PhD Position Cover / Motivation Letter
This rubric looks at whether your letter explains why the specific research work interests you, shows preparation through your own actions, and connects that experience to the work ahead. It also checks whether the writing is clear, grammatically sound, organized, concise, and complete under any instructions that were supplied.
What We Check
The reason for choosing the advertised research work.
What the letter establishes about preparation through the applicant's own work.
The bridge from existing preparation to the work or training offered in the position.
Mistakes We Flag
- Praising the institution instead of the research
- Saying an institution is prestigious does not explain why you want to work on the advertised research problem.
- Using broad interest statements without a research focus
- A statement such as being passionate about science does not show what research question or area draws you to this position.
- Describing team work without your role
- Reviewers need to understand what you personally did, decided, or interpreted in the work you discuss.
- Listing tools or methods without showing how you used them
- A list alone does not demonstrate your preparation. Explain what you did with a method or tool and what you learned from it.
- Claiming you are a perfect fit without explaining the link
- Connect your past preparation to the actual work or training in the position, and distinguish prior experience from what you plan to learn.

Frequently Asked Questions
Is this rubric for any kind of PhD application?
No. It is for one continuous cover or motivation letter for an advertised PhD research position or defined doctoral project. A broad doctoral-program statement of purpose, supervisor inquiry email, standalone proposal, research statement, ranked-project response, or postdoctoral or faculty job letter needs a different review.
Do I need publications or several research projects?
No. Publications, prestigious institutions, paid research, and several projects are not universal requirements. One developed example can demonstrate preparation, including work from study, employment, independent work, volunteering, or transferable methods.
Do I need to propose a new dissertation project or include a literature review?
Not unless the application instructions request it. You can explain an existing project, and the letter does not need to replace the advertised work with a new proposal.
How long should my letter be?
There is no universal word limit or country convention. Follow the vacancy and writing instructions; only an explicitly supplied word or character maximum can be checked from the letter text.
