Letters of Recommendation: Letters from your college Pre-medical Advisory Committee or a college letter service are preferred. You may disregard the waiver forms if a committee or letter service is available. If your college does not have such a committee, appropriate letter writers include science/non-science instructors, employers, community service agency directors/coordinators, and faculty members supervising undergraduate/graduate research experience. No more than THREE letters of recommendation will be accepted. Please indicate in this application which letters we can expect.
You may waive your access to letters of recommendation under the Family Educational Rights and Privacy Act of 1977, and other laws. Please refer to the Waiver of Access to Confidential Letters of Evaluation Form (the link to this file will appear after you submit this application). If you have waived access to your letters through your school's Pre-medical Advisory Committee, it is not necessary to complete the waiver.
