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.
Writing a letter of recommendation can be intimidating, especially because the person you’re writing it for is counting on you to pull through for them. Fortunately, there’s a general formula you can use to write a letter of recommendation that is both professional and effective.
