Rancho Cucamonga Middle, Rancho Cucamonga CA

Original Research by School Decision on Rancho Cucamonga Middle

Rancho Cucamonga Middle is a regular public middle school serving students in grades six through eight in the western San Bernardino County city of Rancho Cucamonga. The school enrolls a student body that is predominantly Hispanic, with a substantial share of students qualifying for free or reduced-price lunch. Roughly four in five students meet the income threshold for that program. The school's racial composition is predominantly Hispanic, with meaningful populations of Black students, Asian students, and other groups represented. The district did not report counts or rates for English learners or students with IEPs, so those populations cannot be described here.

Academically, Rancho Cucamonga Middle shows weaker performance across the state's tested subjects. On the 2024-25 CAASPP Smarter Balanced assessments in English language arts, students in the sixth through eighth grades showed proficiency rates that climb modestly from sixth to eighth grade, with eighth-grade students showing higher attainment in ELA than in earlier grades. Mathematics proficiency rates across the three grade levels are notably lower, running roughly in the high teens to low twenties. The school's overall proficiency index, averaged across tested subjects and grades, places it below the midpoint among schools in San Bernardino County. Science proficiency, measured by the California Science Test in eighth grade, is also in the low twenties. No recent social studies results are available; the most recent data point is from the prior state assessment system in 2012-13. A parent may want to look into what academic supports and targeted interventions the school offers in math, given the gap between language arts and mathematics performance.

Rancho Cucamonga Middle sits in a mid-sized suburb of the Inland Empire that has been growing steadily. The city was incorporated from three older communities in the 1980s and has since transformed from a winegrape-growing region into a suburban residential and commercial center. The housing market in the area reflects suburban pricing typical for the Inland Empire, with homes moderately below the state median. Rental costs run proportionally higher relative to home prices, reflecting the prevalence of multifamily development and rental communities that have grown near the Metrolink station. Major employers span healthcare, pharmaceuticals, food production, and logistics; the city is also home to Chaffey College and is planning mixed-use, transit-oriented development around its Metrolink station as part of a broader growth initiative.

The school serves its middle grades without state-reported information on attendance, discipline, or special-program availability. No district-level policy changes, bond measures, or curriculum initiatives were identified in recent reporting, so the current strategic direction or staffing picture is not available from the data assembled here.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
