Summary

Olympic High is a small public high school serving 233 students in grades 9-12 within the Mt. Diablo Unified district in Concord, operating in a high-need environment where nearly 90% of students qualify for free or reduced-price lunch.

The school faces significant challenges, consistently ranking in the bottom percentiles of California high schools with very low proficiency rates in core subjects and an extremely high chronic absenteeism rate of 86.5%, which is more than four times the district and state averages. This contributes to a graduation rate (67.0%) well below the district average and a high, volatile dropout rate. While the school's small size and low student-teacher ratio suggest potential for personalized support, these have not translated into improved academic outcomes, and its performance is an outlier even when compared to other higher-need schools in the area like Ygnacio Valley High or Mt. Diablo High.

Notably, Olympic High shows a relative strength in serving its Special Education students, ranking in the 61st percentile statewide. However, the school's profound struggles with attendance and academic achievement present a stark contrast to higher-performing nearby schools such as College Park High and Clayton Valley Charter High, indicating a need for systemic intervention and support.
