Summary

Del Norte Elementary is a K-6 public school serving 428 students in the Ontario-Montclair School District, but it faces significant academic challenges, ranking well below both district and state averages in English, math, and science.

The school's performance is notably lower than that of several nearby schools serving similar communities. For example, Edison Elementary, located just over a mile away, achieves much higher test scores despite a similar student population. There is also a pronounced achievement gap between female and male students at Del Norte, and the school has shown inconsistent results year-to-year for English learners and students from low-income families. While chronic student absenteeism has improved dramatically recently, academic performance has declined over the past decade.

Interestingly, Del Norte spends more per student than many higher-performing schools in the area, including Edison Elementary, suggesting that how resources are used is critical. The recent improvement in attendance could be a positive foundation for future growth, and the strong results at comparable schools like Edison and the district's own Online Academy demonstrate that improvement for Del Norte's students is an achievable goal.
