What's something about the education system that parents would be shocked to know ?

I work in education.I'm a special education paraprofessional, and lately.I've realized there are a lot of things that happen behind the scenes.Unschools that parents would probably be very surprised if they actually saw a day to day period i'm not talking about gossip , or calling out specific schools or anything like that , just the realities of the system that most people outside of education don't really understand. So if you have worked or are working in the education system what is something that you think parents would genuinely Shocked to learn ?
