Summary

Alta Loma High is a large public high school serving grades 9-12 with about 2,400 students in the Chaffey Joint Union High district, consistently earning a solid 4-star rating and achieving strong graduation rates well above state averages.

Academically, the school presents a mixed picture: students perform very well in English Language Arts, scoring well above the state average, but face significant challenges in math and science, where proficiency rates have recently fallen below the state average. This gap between subjects is notably larger than at some neighboring schools like Los Osos High and Etiwanda High, which outperform Alta Loma in these areas. A growing concern is chronic absenteeism, which has increased and is higher than the state average, potentially connected to a recent dip in the school's overall statewide ranking.

Despite these academic challenges, Alta Loma High excels in supporting student success, maintaining an excellent graduation rate and demonstrating particular strength in effectively educating English Language Learners and other specific student populations. The school spends more per student than several district peers, suggesting resources are available to address areas needing improvement, such as math instruction and attendance.
