Original Research by School Decision on Chaparral High (continuation)
Chaparral High is a continuation high school in San Dimas, serving students in the upper half of the high school grade band, with no ninth or tenth graders enrolled. As a continuation school within Bonita Unified, it is designed for students who need a setting outside the traditional comprehensive high school, often because credits are behind, previous schooling was interrupted, or other circumstances made a conventional schedule unworkable. The enrollment is small, and a majority of students qualify for free or reduced-price lunch. The student body is predominantly Hispanic, with small numbers of white, Asian, and multiracial students. IEP and English learner data were not available in what was provided.
State assessment results exist for this school, but they need to be read with care. In English language arts, a modest share of students tested at the proficient level; in math, none did. Science scores were suppressed, meaning the tested group was too small to report publicly. These are low numbers by any measure, and a parent should look into this further with the school, understanding both what academic supports are in place and how the school defines progress for students who arrive significantly behind grade level. Continuation schools often serve students whose academic timelines do not match state testing milestones, and a low proficiency rate can reflect that entry point as much as it reflects what the school does with students while they are there. No graduation rate data was provided for this school; that gap likely reflects the nature of continuation settings, where credit recovery and alternative completion pathways make standard four-year graduation rate calculations a poor fit.
No program offerings were available in the data. A comparison with other districts in Los Angeles County was not possible because the school's proficiency, graduation, and attendance metrics either lacked reportable values or were not applicable to this setting.
San Dimas itself sits at the eastern edge of the San Gabriel Valley, at the foot of the San Gabriel Mountains. The city has a Western-themed historic downtown along Bonita Avenue, publicly reported as fairly walkable, with a Saturday-morning street life of coffee, antiques, and local restaurants. Beyond that corridor, the city is largely car-oriented, with chain retail along the freeway corridors. The Bonita Unified district office shares an address on West Allen Avenue with this school, and Chaparral's campus is at that same location. Transit access changed in late 2025 when the Metro Foothill Gold Line extended service to include a San Dimas station, which is publicly reported to connect riders to Pasadena and downtown Los Angeles by train.
Bonita Unified is asking voters to weigh a facilities bond measure to fund repairs and upgrades across all school sites. If passed, property owners in the district would carry an ongoing annual cost per assessed value, layered on top of existing bond obligations. The district is also rolling out ethnic studies coursework beginning in the current school year, aligned with a California requirement that phases in by 2030.
For a family considering Chaparral, the essential question is whether the continuation model is the right fit for their student's situation. This is a small, specialized setting, not a pathway to AP courses or a broad extracurricular life, and the data does not speak to what wraparound services or counseling the school provides. Those conversations belong with the school directly.
