Summary:
Zip code 94546 in Castro Valley, California, is served by three public high schools within the Castro Valley Unified district, including one large comprehensive school, one continuation school, and one very small alternative school, collectively educating over 3,000 students in grades 9-12.
The clear academic leader is Castro Valley High, a top-performing school with a 98% graduation rate, test scores well above state averages, and a low dropout rate. In stark contrast, Redwood Continuation High serves a much smaller, at-risk population with very low proficiency rates, a high chronic absenteeism rate, and a higher dropout rate, despite having more funding per student and a lower student-teacher ratio than the comprehensive high school. The third school, Roy A. Johnson High, is a very small program with only 18 students, the highest per-student spending, and the lowest student-teacher ratio, but its academic performance data is not publicly reported due to its size.
This analysis reveals significant disparities between the schools in this single district. While the district overall is high-performing, the outcomes and resources vary dramatically between school types. The continuation and alternative schools receive more funding per student but serve populations with greater economic need and face significant academic challenges, highlighting different missions within the same community. Parents should understand that the student experience and likely outcomes differ greatly depending on which of these three schools a student attends.
