Summary

Imperial Ave. Holbrook High is a small public high school in Imperial, CA, serving 49 students in grades 9-12 and part of the Imperial Unified School District. Despite its small size, the school faces significant challenges, consistently ranking in the bottom 20-30% of California high schools over the past decade with a 1-2 star rating from SchoolDigger.

With low enrollment and small school size, Imperial Ave. Holbrook High stands out from the nearby high schools, which range from 165 to 1,955 students. The school's performance is consistently underperforming, with its student subgroups, including female, male, Hispanic, and low socioeconomic status students, all ranking in the bottom 15-20% of their respective subgroups in California. Additionally, the school has significantly higher rates of chronic absenteeism (up to 45.1%) and dropout (up to 8.9%) compared to the nearby schools and the state average.

In contrast, the nearby high schools, such as Imperial High, Brawley Union High, and the schools in the Central Union High District, generally perform much better than Imperial Ave. Holbrook High across various metrics, including test scores, graduation rates, and chronic absenteeism. Addressing the unique challenges faced by this small, rural high school will likely require targeted interventions and support to improve student outcomes.
