I don't know if this is common to all the Martians, but John von Neumann was home-schooled by private tutors/governesses until the age of ~10. No doubt he had a broad spectrum of intellectual talents, but his early development at least was based on a one-to-one pastoral footing, not a mass-education school system.

This is how education was traditionally done. If you can at all afford it, take your kid out of the public school system and either home school or find a good private school. In the age of the internet with so many learning materials online and the possibility of zoom tutoring by subject matter experts, it's never been easier to get a fantastic education.
