Tips for writing your Statement of Purpose

by Gordon Haas, SFOS

Most 'statements of purpose' or 'letters of intent' are fine. However, unless you have a funded project and a supervisor lined up, or the rest of your application is impeccable and remarkable, then put substantive efforts into this letter. It really is your only chance to present some personal insights and life beyond the dry numbers provided by your transcripts, GREs, and other such documents. Nowhere else can you directly demonstrate personality, motivation, maturity, interest, enthusiasm, diligence, commitment, and so on. The importance of this letter and its personal attributes become amplified in an application that is in any way 'marginal', or that has no specific faculty supporting or justifying it. Your letter must then be even more able to stand, and be noticed, on its own. Most reviewers are unfortunately (and perhaps understandably) not going to work hard at finding reasons to accept you.

This letter is also your opportunity to account for anything about your 'data' that would benefit from further explanation. You can assist reviewers in their interpretations of your 'record' by highlighting your strongest and most relevant points, especially any not well covered elsewhere in your application. Similarly, you can work to prevent reviewers' misinterpretations or over-simplifications by being candid about any minor shortcomings and by indicating how you are, or will be, addressing those. You can even help by doing things like recalculating your GPA minus a particular course you did poorly in. Such clarifications can, and in some instances should, include extenuating external circumstances, but then be cautious, concise, and do not overdo it. Basically, be clever in, and work at, presenting yourself favourably, but also always remain honest and never promote yourself beyond reasonable reality. Remember that there is the proverbial fine line between saying too much and not saying enough.

What to include in your statement

The rest of your letter should ideally be largely devoted to convincing reviewers that you are amply qualified for, or even better that you will excel at, graduate school. Under more realistic circumstances, you at least want to demonstrate that you understand those qualifications, that you are working well towards them, that you know what you are getting into, and that you want to and have the capacity to succeed. Keep in mind that the letter should be focused on you because reviewers already (should) know their own schools, colleagues, and themselves. You ideally want to demonstrate:

(1) clear well-defined research and/or career interests that do not end with graduate school:

(2) good related academic, employment, and life experience in your chosen or related fields:

(3) an understanding of, and perspective on, 'science', research, and completing graduate school:

Some technical considerations in writing your statement

There are other technical aspects that both facilitate writing a good letter and its review. The letter is a sample of your ability to write and communicate. Be absolutely meticulous about:

(i) brevity

(ii) clarity

(iii) spelling

(iv) grammar and style

(v) other information can be worth examining, but do not get overwhelmed or bogged down.

This 'advice' is at least partly based on other similar documents that I have read over the years. I cannot recall those details, but would like to acknowledge that work. Good luck, and best wishes.

Cheers,
