Too much of that shit going on now. Back in my day, I never heard of such goings on. The worst would be a HS student getting pregnant and having to quit school.
It probably happened from time to time, but societal awareness has changed things a lot. It used to be considered OK, even a bit of a macho plus for a young male to be initiated into sex by an older woman. Now it is (rightfully) considered molestation/rape. The special ed thing is particularly skeevy though, talk about victimization/exploitation of people who may not be capable of giving informed consent even when being 'of age'...
