STAAR proficiency rose +13.1 points from 2022 to 2024. That's the biggest jump among Ontario schools across the two most recent comparable testing years.

About Schools in Ontario, California
Ontario, California has 37 ranked public schools, spanning elementary through middle grades, with an average score of 6.8 out of 10. That average places the city in competitive territory for the Inland Empire region, though performance varies meaningfully across schools. Parents will find a wide range here — from strong performers to schools still building momentum — so where you land in the district matters.
Nearly half of Ontario's ranked schools clear the 7-out-of-10 threshold: 17 schools, or 46%, score 7 or above. That's a solid concentration of higher-performing options for a city this size. Leading the pack is Online Academy, an elementary school scoring 9.1 out of 10 — the highest in the city and a standout by any regional measure. De Anza Middle follows at 8.8, making it one of the stronger middle school options families will find when researching the transition years. On the elementary side, Corona Elementary (8.6), Berlyn Elementary (8.2), and Edison Elementary (8.2) round out the top tier, giving parents in different neighborhoods access to well-rated options without necessarily crossing district lines.
The practical reality for Ontario parents is that school quality is uneven enough to make address research essential. With an average score of 6.8, roughly half of the city's schools fall below that 7-point mark — meaning families who rely on default enrollment without checking performance data may land in a school that underperforms city and state benchmarks. Online Academy's 9.1 score shows what the ceiling looks like, but not every school approaches it.
Parents comparing schools in Ontario should prioritize verified test performance data over reputation or proximity alone. The 46% of schools scoring 7 or above gives families real choices, but those options are distributed unevenly across the city's neighborhoods. Start by confirming which schools your address qualifies for, then use scores and grade-level data to compare directly. The top schools here are genuinely competitive — finding them just takes a focused search.
