Elementary Schools in Ontario-Montclair

The Ontario-Montclair School District includes 27 elementary schools serving grades K-8 in a high-need area of California, where most schools have over 70% of students qualifying for free or reduced-price lunch.

While the district's average test scores are slightly below the state, several schools stand out for strong performance. Top performers include Edison Elementary, the district's highest-ranked school, along with Monte Vista Elementary and the specialized Buena Vista Arts-Integrated, all of which earn 4-star ratings and have exceptionally low chronic absenteeism. Schools like Corona Elementary and Elderberry Elementary also achieve above-average results despite very high poverty rates.

In contrast, schools such as Mariposa Elementary and Berlyn Elementary face significant challenges with low proficiency rates. A notable finding is that schools serving grades K-8, like Edison, show a strong "middle school advantage" with 7th and 8th graders performing far above district averages. The district's Online Academy also defies expectations by having the highest science proficiency rate, suggesting varied and effective educational models exist within the district.
