Public school is a communist remnant idea. The Bible tells us to educate ourselves our kids at home as parents. Now special studies (lawyer, pilot, etc.) are allowed, since Paul was a lawyer and a soldier, and Moses learned all the science from the Egyptians (but he was adopted in the royal family). But you might have to make sure it's from a skilled teacher directly, and not necessarily all that perversion of modern campus. The wicked fallen world wants you to be enslaved to money by being an employee your whole life basically, living in some cavity in a compact city..
