Best High Schools in Zip Code 91311

Zip code 91311 in Chatsworth, California, is served by four public high schools within the Los Angeles Unified district, enrolling nearly 2,000 students across comprehensive, charter, continuation, and community day school models.

Chatsworth Charter High is the clear academic leader, serving the vast majority of students with a 93% graduation rate and the strongest test scores, ranking in the top half of schools statewide. In contrast, the three smaller alternative schools—Stoney Point Continuation, William Tell Aggeler Opportunity High, and Aggeler Community Day—serve specialized at-risk populations and face significant challenges, with much lower graduation rates and rankings in the bottom 20% of the state.

Key insights show a wide disparity in resources and outcomes; for example, Aggeler Community Day spends over five times more per student than Chatsworth Charter High but has less than half the graduation rate, highlighting the complex challenges in alternative education. Parents should note that while chronic absenteeism is relatively low at the charter school, it is exceptionally high at the opportunity schools, and the comprehensive high school achieves stronger academic results at a significantly lower cost per student.
