Our local private school panders to parents and their $$$$. Oooh, little Johnny is sooo smart we gave him straight A’s so where’s next year’s tuition check? When little Johnny decides to attend the local public school, he quickly finds out how far behind he is.
How long has that private school been around?
This is a well-known issue. SAT and ACT scores of students in private schools are higher than that of public schools, but not that much higher. Many of the private school teachers are former public school teachers who basically couldn't take it in public school, so they accepted the lower pay and lower benefits of teaching in a private school. Grade inflation is massive in both public and private schools. If the kids are getting A's the parents don't complain.
