"A statement of purpose should be between 500 and 1,000 words," Pierce advises, emphasizing that it should not be more than a single page. He recommends that students use a classic font in a legible size (11- or 12-pt) with enough whitespace in the margins to make the statement simple to read. Students are also encouraged to include a cover letter when submitting their statements of interest. In addition to being well written and accurate, a statement of interest must also convey two things: it must show an understanding of what graduate schools are looking for in candidates and it must be honest about how you plan to spend your time if you are admitted. Students should take their time writing their statements of interest and try to get feedback from others about their efforts. It's important that they find something interesting to say about themselves that will make them stand out from the rest of the pool of applicants. This way, they increase their chances of being invited for interviews.
