1. Who should write my letters?

You should have letters from people who can comment on your experience and abilities relevant to graduate study in your chosen field and relevant to the professional work you will ultimately be doing. Generally, it is best to have some letters from professors in your academic major. Professional schools often look for letters from employers as well as from instructors. As Ph.D. programs focus a great deal on research and teaching, they put special emphasis on letters from professors who can attest to the applicant's scholarly potential.

The strongest letters of reference grow out of an established relationship. Start early! Visit your professors and make sure that you take some small classes or individual study.
