About Repit School Scores
Traditional school ratings rely heavily on standardized test scores, which often reflect family income more than actual school quality. Repit takes a different approach.
We evaluate schools based on factors that research shows actually impact educational outcomes:
- Class Size — Smaller classes mean more individual attention and better student outcomes.
- School Funding — Resources available for programs, teachers, and facilities directly affect education quality.
- School Environment — School size and structure affect available programs and student experience.
