What is your school-choice missing 20%?
Every setup has something worth keeping and something that keeps nagging at you. Name both, then get the gap you are actually trying to solve.
Homeschool families often name extras and community. Microschool families often worry about proof of rigor. Private school families often feel the pressure running too hot.
The goal is not a perfect model. It is keeping the 80% that works and building support around the missing 20%.
