Great find.

Here is an excerpt from a 2016 Wall Street Journal essay on the enormous problem of child sexual abuse in schools:

"Predators in the Classroom"

Ms. Miller is candid when asked how many American children have been sexually abused by teachers and other school employees: She doesn’t know with any certainty.

The best that she—or anyone else—can do is to cite a 2004 study funded by the U.S. Department of Education that surveyed the existing literature at the time.

Overall, 9.6% of the [2,065] students reported experiencing one or both sorts of unwanted attention from school personnel ['noncontact” sexual misconduct involving such things as lewd comments or pornographic images, and/or more serious misconduct: touching, kissing, grabbing clothing, forcible sexual contact.']
