This article where AFT head Randi Weingarten said ""We're not indoctrinating, We're not grooming. … What we're doing is making sure we educate kids. We keep them safe. We keep them welcome. And we teach them how to think, not what to think." got me searching for empirical research on sexual misconduct in schools.
In short, NOBODY is really researching the subject. This was the best research I could find, and it allows us to put a number on the problem.
