FAQ

Why count aides as 0.5? +
Aides supplement but are not lead instructors. Most state ratio rules count them at a fraction (typically 0.5) when calculating compliance.
What is a good ratio? +
Below 12:1 enables truly individualized learning. Most successful microschools sit at 10:1 to 15:1. Above 20:1 starts feeling like traditional school.
