Edison Elementary, Ontario CA - Test Scores & Data

Original Research by School Decision on Edison Elementary

Edison Elementary is a kindergarten-through-eighth-grade school in Ontario serving a student body where roughly three-quarters come from families qualifying for free or reduced-price lunch, and the majority are Hispanic. The school sits in the established part of Ontario, near the city's historic downtown along Euclid Avenue, in a community defined by both a walkable civic core and car-dependent suburban neighborhoods.

The testing data from the most recent year shows a profile with real strengths in the upper middle grades and evident work needed in the elementary grades. In English language arts, Edison performed strongly in grades seven and eight, with proficiency rates well above what you would see in a struggling school. Writing and reading comprehension appear solid at that level. In grades three through six, ELA proficiency falls into a moderate range, and the fourth-grade cohort showed the lowest rate of the younger grades. Mathematics is where the grade-by-grade pattern becomes clearer: third grade shows proficiency in the mid-range, fourth and fifth grades dip noticeably lower, and then sixth through eighth grades show a marked recovery, with seventh and eighth graders reaching high proficiency. Science proficiency in fifth grade was below half the students, though by eighth grade it climbed substantially. Across all tested subjects and grades, Edison's overall proficiency index places it in the top quartile among schools in San Bernardino County, which is a meaningful strength given that the county includes a range of school performance levels.

The combination of stronger performance in the upper grades and notably lower math proficiency in grades four and five suggests a transition pattern worth understanding. A parent may want to look into this further with the school, particularly if they have a student entering the middle-grade years. The upper-grade strength is real and consistent across subjects, but the elementary math dip is visible in the data.

The school enrolls a student body that is predominantly Hispanic and includes a substantial share of students learning English. More than seventy percent of the school receives free or reduced-price lunch. No data on the percentage of students with IEPs or English learners was available. The school draws from a neighborhood that has been stable Ontario for decades, though the larger city is experiencing rapid growth driven by Ontario Ranch, a massive master-planned community on the southern edge. That growth may eventually reshape school enrollment, but it has not yet transformed Edison's immediate catchment.

The housing market in Ontario's zip code has held relatively steady in value, and rents have remained modest by California standards, though affordability remains a challenge relative to median household income. The city itself is a logistics, distribution, and retail hub with major employers including the airport, health systems, and national retailers. Euclid Avenue downtown is genuinely walkable with parks, civic facilities, and a library anchor, though many parts of Ontario require a car for daily life.

Edison is not a choice school; it is a neighborhood public elementary and middle school. The testing profile shows it has invested in upper-grade instruction with measurable results. The lower elementary and early-middle-grade math performance deserves conversation with the school staff about curriculum, supports, and the pathway students take as they move up. For families in the zone, it is worth visiting and asking directly about that fourth- and fifth-grade math experience and what instructional moves have lifted grades seven and eight.

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.
