“The current contract is not renewed and the teacher skulks off to a new district with a clean record.”
You must be unaware of how school districts, from sheer terror caused by liability, bend over backwards to vet their teachers. Potential candidates are finger printed, which are then sent in, and teachers have to sign over all rights to privacy pertaining to criminal records and credit scores.
We see all the time the pictures of teachers in the news who have been arrested. That cannot be hidden away. Their teaching career is over.
Teachers who have never been charged do not have criminal records. That’s what passing the trash is, sending the problem somewhere else, before they become a legal liability by being reported. If you think school officials don’t discourage kids from reporting then you just aren’t paying attention.
The current statistic is 1 in 10 students report experiencing unwanted sexual behavior from a teacher or coach.
