One thing that stood out to me, I went from a private school with a class of 16 to a state (grammar) school with a class of 28. That does have an affect on teaching.

However also anecdotally a friend taught at a private school for a couple of years. Parents made it quite clear that it was his responsibility to ensure their angels passed the exams, no matter how thick they were. He didn't stay for long due to that attitude.
