Eh, injuries at phys ed classes tend to be along the lines of, “he slipped, and accidentally hit something hard enough to cause damage”. Not anything that anyone is likely to try to do cover up. Although, i guess I’ve never had an incident where i called anyone for help. We once had a woman (who wasn’t a student, our students dance with community members, too) fall and sprain her ankle near the end of the evening. At her request, I took her to urgent care after the dance. (Because i had a car.) That’s the worst injury i can remember.
I have no idea what the students are told to do if someone assaults them.
