Summary

Charter Oak High is a public high school serving grades 9-12 for about 1,260 students in Covina, California, and is part of the Charter Oak Unified district, where it stands out for its exceptionally strong graduation rate of 98.1% and a remarkably low dropout rate of 0.3%, both significantly better than state averages and comparable or better than nearby schools like South Hills High and San Dimas High.

The school shows clear academic strengths, particularly in English Language Arts, where 60.6% of students are proficient, outperforming the state average and holding its own against neighbors such as Covina High. It also does a good job managing chronic absenteeism. However, parents should note that math and science proficiency are areas for growth, lagging behind both state and district averages, and performance support for specific student subgroups has shown significant volatility from year to year.

Overall, Charter Oak High delivers very strong results in keeping students in school and graduating them, especially considering the economic challenges many students face. While it competes well with schools in other districts on key metrics, its performance in core subjects like math and science, when compared to schools like San Dimas High, indicates there is room for improvement to ensure all students are equally prepared for their next steps after graduation.
