A couple of private school systems, which are much more attuned to actual education rather than indoctrination are the Waldorf system and the Montessori system. Both are very expensive but if you can afford it they are both extremely good education systems.

If your curious about these systems I encourage you to watch some youtube videos on these education types to see how they work, and see them in action.
