We evaluate schools based on factors that research shows actually impact educational outcomes:

  • Class Size — Smaller classes mean more individual attention
  • School Funding — Resources available for programs, staff, and facilities
  • Community Factors — Neighborhood characteristics that influence student success
  • School Environment — Size, type, and structure

Scores are updated annually using federal education data.
