Summary:
The Castro Valley Unified district operates three high schools serving grades 9-12, with a total enrollment near 3,000 students, and the district as a whole is rated above average, performing better than 85% of districts in California.
The standout comprehensive school is Castro Valley High, which serves the vast majority of students and excels with a 98% graduation rate and test scores well above state averages, particularly in English. In contrast, Redwood Continuation High is a much smaller alternative program focused on supporting at-risk students, facing significant challenges with chronic absenteeism and lower test proficiency despite higher per-student spending. The third school, Roy A. Johnson High, is a very small specialized program with only 18 students and the highest per-student spending in the district.
Key takeaways show a district effectively providing two educational tracks: a high-performing main high school and targeted intervention programs. While Castro Valley High maintains strong and consistent results, the continuation school's high absenteeism rate is a major concern. The district's mathematics scores, though solid, are an area where even the top school has room for growth compared to its exceptional English performance.
