Why should I use the Letter Service at the Career Center? If you are applying to more than three schools, or you think you want your letters held for other opportunities (like law school) in the future, you should plan to use the Letter Service. Your letter writers will write one letter and fill out one form, rather than filling out a different form for every application.
The most effective letters of recommendation are written by professors or work supervisors who know you well enough to describe your academic, personal, or professional achievements and potential with candor, detail, and objectivity. Letters that compare you to your academic peers are often the most useful. Most schools do not consider general, unreservedly praiseworthy letters helpful.
