A statement of purpose should portray me as (1) passionately interested in the field; (2) intelligent; (3) well-prepared academically and personally; (4) able to take on the challenges of grad school; (5) able to have rapport with professors and fellow grad students — in other words, collegial; (6) able to finish the graduate degree in a timely fashion; and (7) a potentially outstanding representative of that grad school in your future career.
It should be organized (1) passionate hook; (2) segue to your background in the field; (3) specific classes by title and professors you have had (especially if well-known in the field); (4) related extracurricular activities (especially if they hint at some personal quality you want to convey); (5) any publications or other professional accomplishments in the field (perhaps conference presentations or public readings); (6) explanations about problems in your background (if needed); and (7) why you have chosen this grad school (name one or two professors and what you know of their specific areas or some feature of the program which specifically attracts you).
