How do we ensure schools employ only teachers we trust? Whats the criteria and initial/review process?

Also, teachers are human. They change views and opinions like the rest of us. What guarantees they don't break that trust?

I’m active in local government - that’s how you make sure the school board is strong and the superintendent is the best candidate. But also voting is effective.

But there are no guarantees - except that those who wish to ban access to books are never to be trusted.
