Summary

Glendora High is a large, comprehensive public high school serving grades 9-12 to approximately 2,069 students in the Glendora Unified school district, consistently ranking in the top 16% of all California high schools.

The school excels in key areas, boasting an exceptional 97.9% graduation rate and a very low 0.6% dropout rate, which are significantly better than state averages and outperform nearby schools like Azusa High and Charter Oak High. Students also show strong proficiency in English (71.89%) and Math (54.68%), and the school maintains remarkably low chronic absenteeism at 8.8%, less than half the state average. While San Dimas High ranks slightly higher overall, Glendora competes closely, often with better math scores and attendance.

Notably, Glendora High achieves these strong results while spending less per student than many neighboring schools, and it earns particularly high marks for the performance of its economically disadvantaged students. The school shows consistent strength across most student groups, though there is room for growth in science proficiency and support for specific subgroups like special education students. The dramatic performance gap between Glendora High and local continuation schools highlights the effectiveness of its mainstream educational model in keeping students engaged and on track for success.
