Summary

Los Altos High is a large public high school serving grades 9-12 to about 1,600 students in Hacienda Heights, operating as part of the Hacienda la Puente Unified school district.

The school has clear strengths, particularly in English Language Arts where student proficiency significantly outpaces both the district and state averages, and it excels at supporting English Learners. It maintains a very high graduation rate of nearly 95% and has lower chronic absenteeism than many neighboring schools like La Puente High and William Workman High. However, the school faces notable challenges in mathematics and science, where proficiency rates are below average, creating a significant performance gap when compared to a nearby school in the same district, Glen A. Wilson High.

Overall, Los Altos High is a solid, efficiently-run school that successfully graduates the vast majority of its students and provides strong support in key areas, though families should be aware of the academic discrepancies between subjects and how the school compares to others in the area like Mountain View High. Its consistent graduation success suggests effective student support systems that keep learners on track to complete their diplomas.
