For all sports, physicals are good for a calendar year ranging from May 1 to May 1. This is TSSAA policy. If you have a physical on April 30, it is only good for that day. All physicals are good for all sports from May 1 to April 30.
For MS athletics, eligibility is based solely on the quarter preceding the sport. If your athlete fails more than one class the quarter before the sport begins, he or she will not be allowed to participate. For fall sports, the Q4 grade from the previous year is all that is used to determine eligibility, not Y1 or S2.
