Summary

Castro Valley High is a large, comprehensive public high school serving about 2,874 students in grades 9-12 within the highly-regarded Castro Valley Unified school district, ranking it among the top 15% of districts in California.

This school stands out as an exceptional performer in its region, consistently earning a 4-star rating and ranking in the 90th percentile of all California high schools. Its 98% graduation rate and very low dropout rate far exceed state averages and those of neighboring schools like San Leandro High and Hayward High. Students at Castro Valley High show strong proficiency in core subjects, especially English, and the school maintains a lower rate of chronic absenteeism than most area schools, contributing to its stable success.

Notably, the school achieves these excellent outcomes efficiently, spending less per student than many nearby schools with poorer results. While it serves all students well, there is a focus on supporting an economically diverse population, and math scores, though above average, are an area for growth relative to its own high standards. The performance gap is significant when compared to alternative schools in the same district, such as Redwood Continuation High, highlighting Castro Valley High's effectiveness as a mainstream academic institution.
