School Overview

Ontario High sits in the heart of the Inland Empire, a sprawling region east of Los Angeles where working families have long put down roots drawn by more affordable living and a tight-knit community feel. The school lands solidly in the middle of the pack statewide, with English and Math scores that trend above average, though families with strong science-focused students may want to factor in that the school scores lower in that subject. It's a good fit for families looking for a neighborhood school with genuine community ties in a city that feels more grounded and less transient than many of its Southern California neighbors.
