 In football and soccer, students are not allowed to play on the varsity until they are actually enrolled in the ninth grade, and wrestlers cannot compete until they have entered the seventh grade.In other sports, there is no grade restriction; for example, current NBA player O. J. Mayo first played on a high school varsity team as a seventh-grader at Rose Hill Christian School in Ashland, and current PGA Tour golfer JB Holmes first played on the golf team of Taylor County High School in Campbellsville while in the third grade.The eligibility "clock" for such students does not start until they enter ninth grade.
