Ontario-Montclair


Summary:

The Ontario-Montclair school district serves roughly 17,000 students across 33 elementary and middle schools in a community where most families face economic challenges.

While the district's test scores generally lag behind state averages, especially in science, several schools stand out for strong performance. Edison Elementary is the top-ranked school, followed by other high performers like Monte Vista Elementary and Buena Vista Arts-Integrated. On the other end, schools such as Mariposa Elementary and Vina Danks Middle rank significantly lower and are identified as needing improvement.

Key insights show that higher student attendance is strongly linked to better academic results, and surprisingly, the highest-performing school has the lowest per-student spending in the district. The Online Academy shows promise with its students scoring well in math and science. For parents, this means success is possible at many district schools, with a focus on consistent attendance and the specific programs offered at each campus being important factors to consider.
