Psychiatrists function in various ways in the admissions process of medical schools. They serve on admissions committees, act as consultants, and provide expertise in evaluating applicants known to be at psychological risk. The authors discuss the pros and cons of broadening admissions criteria; the assessment of the diagnosis, functioning, and prognosis of an applicant; the supportive services necessary for students screened into medical school; and the avoidance of homogenization of medical students. They conclude that the participation of psychiatrists is critical to the efficient operation of the admissions process and the medical school itself.
