ALT The verification would need to be based on at least one of the following: "the student's reproductive anatomy, genetic makeup, or normal endogenously produced testosterone levels," the measure's text says. I-638 proponents say those requirements would create no new hurdles for girls, since all students already must have a physical examination before competing in sports. But the statewide group that governs middle- and high-school athletics — the Washington Interscholastic Activities Association (WIAA) — says its current rules don't require visual checks of girls' genitals, DNA testing or hormone testing. Right now, students must obtain a medical professional's written clearance confirming they are fit to participate, according to the WIAA Handbook. The only required elements of the physical exam are a review of the student's medical history, a cardiopulmonary examination and a sport-specific orthopedic screening.
