Which of the following best describes when a prospective student-athlete can work for the athletics department?

The correct answer is that a prospective student-athlete can work for the athletics department after high school graduation. This aligns with NCAA regulations, which specify that a prospective student-athlete, defined as someone who has not yet enrolled in college, is not permitted to receive any benefits or services from the college's athletics department prior to graduation from high school.

This prohibition ensures a clear boundary between high school athletics and collegiate athletics, thereby maintaining the amateur status of prospective student-athletes until they officially enter college. As soon as a prospective student-athlete graduates from high school, they can be employed by the athletics department under certain conditions if they meet NCAA guidelines and the specific institution's protocols.

The other options suggest scenarios that do not comply with NCAA rules regarding employment for prospective student-athletes. For instance, registration for courses and receiving a scholarship only apply after enrollment in the institution, which cannot happen until after high school graduation. Additionally, working "anytime prior to commencement" includes a broad time frame that conflicts with the NCAA's restrictions on benefits to prospective student-athletes.
