Summary:
Two high schools serve zip code 94598 in Walnut Creek, CA: Northgate High, a large comprehensive 9-12 school in the Mt. Diablo Unified district, and the smaller Contra Costa School of Performing Arts, a specialized 6-12 magnet school in its own Contra Costa School of Performing Arts District.
Northgate High stands out as a consistently high-performing school, ranking in the 90th-94th percentile statewide over recent years with a 98.7% graduation rate and academic proficiency rates well above state averages in English, math, and science. In contrast, Contra Costa School of Performing Arts has shown more variability in its rankings and has proficiency rates below the state average, though it serves a distinct purpose with its focused arts curriculum for grades 6-12.
A notable finding is the dramatic difference in per-student spending, with the arts school spending nearly ten times more than Northgate, yet Northgate demonstrates stronger academic outcomes and lower dropout and chronic absenteeism rates. This comparison highlights the different educational models available in the area: a large, traditional high school achieving broad academic success and a specialized arts school catering to specific student interests, with each serving different roles within the community.
