Frequently asked questions

What is the best charter school in Philadelphia?

Green Woods CS in Philadelphia, Pennsylvania ranks first among charter schools in Philadelphia with a Success Index (US) of 65.3 out of 100 (Enrollment: 699).

How are charter schools in Philadelphia ranked?

Each school's Success Index (US) combines 4 factors: math proficiency (30%), reading proficiency (30%), community advantage (fewer free/reduced-price lunch) (25%), students per teacher (15%). Each factor is a percentile against schools of the same type across United States. Schools with fewer than 60 students are excluded from rankings.

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). States set their own assessments and proficiency cut scores, so proficiency rates are most comparable within a state. Use the state rankings for like-for-like comparisons.
