Frequently asked questions

What is the best public school in Pomona Unified?

Pantera Elementary in Diamond Bar, California ranks first among traditional public schools in Pomona Unified with a Success Index (US) of 69.7 out of 100 (Enrollment: 512).

How are traditional public schools in Pomona Unified ranked?

Are these 2025 rankings official?

No. They are computed by Success Tutoring from official American data (Urban Institute Education Data Portal (NCES CCD, EDFacts); NCES Common Core of Data).
