Its nearly impossible to visit classrooms in most schools now. That's on purpose. Any school that tells YOU the parent that YOU can't see your own child in his classroom without a background check is a school you need to leave. Right now at once immediately.

But if you get to set foot inside, you would see the slovenliness of the students. They wear their pajamas to school. You'd see the staff they hire aren't capable of stringing together a coherent sentence. You would see elementary schools with silent lunch and no talking allowed during carpool pickup. You would see KGB-TQIA+ posters everywhere but no math ever. Funniest thing my kid saw when he went to take the PSAT was a poster that said "Don't say Gay! Say "stupid" "dumb" "lame" "loser" ..."(and a few more I can't remember.) My kid came home laughing "synonyms, what are they?"

Schools are prisons. Free your kids.
