Which of the following is NOT a requirement for appointment to Officer Candidate School?

The requirement that is not necessary for appointment to Officer Candidate School is the completion of a physical fitness test. While physical fitness is an important aspect of military training and service, and candidates are often evaluated on their fitness levels, a specific physical fitness test is not a formal requirement for entry into Officer Candidate School itself. Candidates will, however, be expected to maintain a certain level of physical fitness throughout their training and military service.

On the other hand, U.S. citizenship, having a high school diploma or GED, and a clean criminal record are all established prerequisites for entering Officer Candidate School. U.S. citizenship is essential because the military requires officers to uphold and protect the nation. A high school diploma or GED is considered the minimum educational qualification, ensuring that candidates have a foundational level of education. Lastly, having no criminal record aligns with the military's standards for integrity and character, which are critical for leadership positions within the armed forces.
