Summary:

The Grossmont Union High district consists of 15 high schools serving grades 9-12 in the San Diego area, showing a wide range of performance and student experiences.

Standout schools include Grossmont Middle College High, an exceptional small school ranking in the state's top 1%, and traditional high schools like West Hills High and Valhalla High, which consistently achieve high graduation rates and test scores. In contrast, some alternative schools, such as Chaparral High and MERIT Academy, face significant challenges with very low graduation rates.

Key district findings include a notable weakness in mathematics proficiency compared to the state average and a widespread issue with chronic student absenteeism, particularly in alternative programs. Interestingly, higher per-student spending does not guarantee better outcomes, as some of the highest-funded schools struggle the most. Parents should note that smaller schools in the district show extreme variation, from top-tier performance to severe difficulties, while most traditional high schools perform near or above state averages in English Language Arts.
