Summary

Clayton Valley Charter High is a large, well-regarded public charter school serving over 2,300 students in grades 9-12 in Concord, consistently earning a 4-star rating for its strong academic performance and exceptional student outcomes.

The school truly stands out for its remarkable student engagement, boasting a near-perfect 95.8% graduation rate and an astonishingly low chronic absenteeism rate of just 0.1%, which is far better than the state average and most nearby schools.
