Each applicant must have three letters of reference. They must have one letter from their math or science teacher, one letter from their principal or counselor, and one letter from an additional community member (i.e.: coach, clergy, scout leader, employer, additional teachers, etc. Family members may not serve as references.) Except in special circumstances, letters of recommendation must be addressed to Congressman Buck, not to another member of Congress. Late letters of recommendation cannot be accepted, and applicants who are missing letters cannot be interviewed.
