Summary

Oak Knoll Alternative is a K-12 school in Glendora serving about 107 students within the Charter Oak Unified district, notable for its strong English Language Arts performance and recent, significant improvement in graduation rates.

The school shows a clear strength in English, with proficiency rates close to state and district averages, often outperforming nearby alternative schools like Puente Hills High. However, it faces major challenges in Mathematics and Science, where scores are significantly below average; for example, 11th-grade math proficiency was 0% in the last school year. On a positive note, student engagement appears stronger than at many peers, as the chronic absenteeism rate is much lower than at schools such as Pomona Alternative or Rowland Virtual Learning Academy.

Recent trends show the school is serving more economically disadvantaged students, and the student-teacher ratio has increased. Despite these challenges, the 2024-2025 graduation rate of 94.1% is the highest among comparable local alternative schools and exceeds the state average. For families, the school represents an environment with notable success in keeping students engaged and graduating, but one where targeted support in math and science would be crucial for academic balance.
