Summary

Ontario High is a large public high school serving approximately 2,000 students in grades 9-12 within the well-regarded Chaffey Joint Union High district in Ontario, CA, where it stands out for its strong graduation rate and English Language Arts performance despite serving a community with significant economic need.

The school's 94.5% graduation rate is a major strength, exceeding both state and district averages and rivaling nearby schools like Don Antonio Lugo High. Ontario High is also notably effective in English, with over 62% of students proficient, a rate that beats the state average and is competitive with most neighbors, though slightly behind Montclair High. However, the school faces clear challenges in mathematics and science, where proficiency rates lag behind the state average, a gap that is common in the area but presents a key opportunity for growth.

Attendance is a pressing concern, with chronic absenteeism at 32.5%, higher than the state average and an issue shared with other schools in the Chaffey Joint Union High district. Compared to smaller schools like Village Academy High School at Indian Hill, Ontario High's larger size may impact resource allocation, though its per-student spending is in the mid-range for the region. Overall, the school demonstrates a consistent ability to support its diverse student body toward graduation, while working to improve mastery in core technical subjects and daily attendance.
