When a student athlete first enters ninth grade, he then is eligible for four consecutive school years (eight semesters) for participation in interscholastic athletics. For example, a student athlete repeating a grade after entering ninth grade, would be ineligible in their fifth year of high school.Under the “Period of Participation” rule, there are no “redshirt “ years, and not playing a season in a given sport one year does not give a student athlete an additional season of eligibility to play that sport. Regardless of where the student athlete begins ninth grade, in another state, country or at home (home school), the semester clock begins and carries over to enrollment in a school in Pennsylvania that is a member of the PIAA.
More information regarding athletic eligibility can be found on the PIAA website
