Every 5 year old should be evaluated without exception. Ideally the test would be with shapes and pattern recognition that is not culturally determined or where the rich can't get an advantage.
130+ children should be partly segregated, allowed to attend normal classes with acceleration and additional support.
145+ children should be completely segregated, socializing with their equals, and only taught by teachers at the same level.

No normie should be allowed to harm these national treasures, whether it be a school administrator, ordinary teacher, or slack-jawed yokel age mate.
