Evaluation Criteria

When we say “top-rated,” we weigh more than test scores. Our rubric focuses on:
  1. Teaching Philosophy & Innovation – mastery-based, Montessori, IB, language immersion, or one-to-one models that replace passive lectures with active inquiry.
  2. Accreditation & Outcomes – Cognia, ISAS, AWSNA, IB, or similar recognition plus transparent graduate success (college acceptances, portfolios, apprenticeships).
  3. Student Support & Ratios – counseling, advisory, SEL, and class sizes under 18; lower ratios earn higher marks.
  4. Whole-Child Enrichment – arts, entrepreneurship, service learning, outdoor education, and real-world partnerships.
  5. Community Fit – diversity, inclusion practices, family engagement, and scheduling flexibility.

Why Alpha School Austin Stands Out

Alpha’s downtown campus turns school on its head: two laser-focused academic hours powered by adaptive software, then afternoons of passion projects—from podcast production to building solar ovens at Lady Bird Lake. Low ratios mean guides know every child’s strengths and gaps, and weekly “Test2Pass” demos let students showcase mastery to peers. Families praise the secular environment, intentional diversity (no group > 20 % of enrollment), and real-world skills such as networking with local founders. Curious?
