Original Research by School Decision on Montclair High
Montclair High is a standard public high school serving grades nine through twelve in the city of Montclair, a densely built post-war suburb at the western edge of the Inland Empire in southwestern San Bernardino County. The school sits in a community of roughly mid-sized population characterized by modest mid-century single-family homes and apartments, with some of the region's more accessible housing costs and a strong immigrant presence. The housing market shows stable valuations near the county midpoint, though mortgage costs relative to local income remain substantial. The city itself is undergoing active redevelopment, with transit-oriented mixed-use projects underway around the Montclair Transit Center, though the overall built environment remains car-dependent and sprawling.
The school enrolls a student body that is overwhelmingly Hispanic, with a substantial share of students qualifying for free or reduced-price lunch. The enrollment is mid-sized for a four-year comprehensive high school. No data on students with disabilities or English learners was available, so families may want to ask the school directly about those populations and the supports in place for each.
On state testing, Montclair High's performance shows a pronounced divide between language arts and mathematics. In English language arts, students achieved proficiency at a solid rate. In mathematics and science, however, proficiency fell to a much lower level, with fewer than a third of students meeting the standard in either subject. This pattern suggests that while the school has built stronger capacity in reading and writing, it faces material challenges in quantitative and scientific reasoning. Given that these assessments span all four grade levels tested, the performance reflects consistent gaps across the high school years rather than a particular grade-level issue. Only the most recent year of testing results was available, so trends over time cannot be assessed.
The district, Chaffey Joint Union High, has recently expanded AP course offerings, including the introduction of AP African American Studies as a college-credit pathway designed to reach students new to Advanced Placement work. The district also cites planning for ethnic studies coursework in response to state graduation requirements that are currently on hold pending state funding. These moves align with the district's college-and-career-readiness mission and reflect a deliberate effort to broaden access to rigorous, post-secondary-credit coursework beyond traditional advanced tracks.
Data on graduation rates, chronic absenteeism, discipline, attendance, and staffing were not available for this school, so families should request those directly from Montclair High or its district office to get a fuller picture of school climate and completion outcomes. Similarly, comparisons to other schools in San Bernardino County are limited because graduation and chronic absenteeism data, which are key measures for positioning high schools, were not reported.
For families considering Montclair High, the school offers a standard comprehensive high school experience in a community actively reshaping itself through transit-oriented development. The student body is predominantly Hispanic and economically disadvantaged, and the school serves that community with some breadth of course options. The mathematics and science performance gap is a concrete area where students will benefit from extra support or intervention, particularly if they are planning post-secondary pathways that demand quantitative skills.
