Summary

Acalanes High is a top-performing public high school serving grades 9-12 with about 1,256 students in the affluent community of Lafayette, part of the highly-regarded Acalanes Union High district.

The school consistently ranks in the top 5% of California high schools, with graduation rates over 95% and academic proficiency well above state averages, particularly in English. It's important to understand that Acalanes High is part of an exceptional cluster of schools; within its own district, it is the third-highest ranked among traditional comprehensive high schools, behind Miramonte High and Campolindo High, but ahead of Las Lomas High. This means families in this area have access to several outstanding options.

While Acalanes High is a strong school overall, recent data shows significant year-to-year drops in standardized test performance for some student groups, including Asian, multi-racial, and low-income students, which the school may be addressing. The school has historically been very effective for students with disabilities. Compared to schools in the neighboring Mt. Diablo Unified district, such as Northgate High or Ygnacio Valley High, Acalanes enjoys substantially higher funding and academic outcomes, highlighting stark differences between nearby districts.
