Los Amigos Elementary, Rancho Cucamonga CA

Original Research by School Decision on Los Amigos Elementary

Los Amigos Elementary serves kindergarten through fifth grade in Rancho Cucamonga, a mid-sized Inland Empire suburb that has grown substantially over the past two decades. The school sits in a diverse residential area where most families work in healthcare, technology, construction, or logistics. It is not a charter or magnet school; it is a regular public elementary school in the Cucamonga Elementary School District.

The student body is predominantly Hispanic, with a substantial share of Black students and smaller populations of Asian, white, and Native Hawaiian or Pacific Islander students. A substantial majority of students qualify for free or reduced-price lunch, reflecting the economic profile of the school's attendance area. The school has fewer than six hundred students across all grades. State-tested English learner and special education enrollment data were not available in the public record.

Academic performance on California's state assessments is low across both English language arts and mathematics. In fifth-grade English language arts, proficiency is somewhat higher than in the earlier grades and in math, but still substantially below the state median. Third and fourth graders show proficiency in the low range in both subjects. Fifth-grade science proficiency is similarly low. When looking at overall proficiency across all tested grades and subjects, Los Amigos falls in the bottom quartile among school-level results in San Bernardino County. The data presented here covers only the most recent school year; historical trend data was not available, so it is not possible to say whether performance is improving or declining.

Because the school serves only elementary grades, there is no graduation rate or high school course access data.

The broader context matters. Rancho Cucamonga itself is experiencing sustained residential and commercial growth, particularly in the HART District near the Metrolink station and around new mixed-use development. Housing values in the 91730 zip code (where the school is located) have held relatively stable, though rents have declined slightly. Major local employers span healthcare, pharmaceuticals, and logistics. The city has been deliberately building more walkable areas and transit connections, moving away from pure automobile dependence, though much of the city remains suburban and car-oriented.

Families considering this school should understand that the academic proficiency numbers are materially low. A parent may want to reach out directly to the school about its instructional approaches, how it supports students who are working below grade level, what supplemental resources are available, and how the school communicates progress to families. The enrollment is stable and the school is embedded in a neighborhood with parks, retail, and community anchors nearby. For families prioritizing strong early-grade academics or seeking a school with higher test outcomes, this profile suggests looking at other options within the district or county.

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.
