 As such, junior varsity teams are used to prepare these athletes to compete at varsity level.In other schools, the line between JV and varsity is arbitrary, with all players at a certain grade level (usually seniors and, in smaller schools, juniors) at varsity and all others below that grade level at JV, with only a few exceptions for highly talented (or well-connected) student athletes, or much smaller schools where - due to their low enrollment - are limited in the number of upperclassmen athletes.Some teams require participation on a junior varsity team before being eligible to try out for a varsity team.
