Summary

Troy High is a large, comprehensive public high school serving grades 9-12 with approximately 2,504 students in Fullerton Joint Union High district, consistently ranking among the top 2-3% of all California high schools for over a decade.

The school's academic performance is exceptional, with proficiency rates of 87% in English, 78% in Math, and 75% in Science, far exceeding both district and state averages. This success is remarkably consistent across diverse student groups and is achieved with per-student spending similar to nearby schools. Notably, Troy High maintains a very low chronic absenteeism rate of 9.7%, which is about half the state average and contributes to its 95% graduation rate.

When compared to other comprehensive high schools in the area, the difference is striking. For example, Sonora High and Fullerton Union High have math proficiency rates less than half of Troy's, while Sunny Hills High and El Dorado High also show significant gaps. This demonstrates that within the same geographic area and with comparable resources, school-level factors at Troy High drive outstanding and stable results for all its students.
