To be admitted, candidates must be between seventeen and twenty-three years of age upon entrance, unmarried with no children, and of good moral character. The current process includes a college application, personality testing, standardized testing, and personal references. Candidates for admission must also undergo a physical aptitude test (the CFA or Candidate Fitness Assessment the Physical Readiness Examination) as well as a complete physical exam including a separate visual acuity test to be eligible for appointment. A medical waiver will automatically be sought on behalf of candidates with less than 20/20 vision, as well as a range of other injuries or illnesses. The physical aptitude test is most often administered by a high school physical education teacher or sports team coach.
