Summary:
This analysis covers 13 public schools in the 91761 zip code of Ontario, California, serving approximately 8,055 students from kindergarten through 12th grade across four districts: Chaffey Joint Union High, Mountain View Elementary, Ontario-Montclair, and Chino Valley Unified.
Academic performance varies widely, with standout schools including Park View Elementary (ranking in the 86th percentile statewide) and Grace Yokley Junior High, while others like Mountain View Elementary and Bon View Elementary rank significantly lower. The area's only high school, Colony High, has a concerning chronic absenteeism rate of 31.4% and a math proficiency of just 20.95%, though it maintains an 88.8% graduation rate.
Key findings show that higher per-student spending does not guarantee better results, and mathematics is a universal challenge across all schools. The small Online Academy presents an interesting success case with strong test scores and very low absenteeism despite serving a high-need population. Parents should note the significant differences in performance between schools within the same geographic area and even within the same district.
