Summary

Walnut High is a large, comprehensive public high school serving grades 9-12 and approximately 2,150 students in the consistently top-ranked Walnut Valley Unified school district.

The school is a model of consistent excellence, ranking in the state's 95th percentile and boasting graduation rates above 97% with proficiency rates that far exceed state averages, especially in English Language Arts. It achieves these outstanding results with efficient use of resources, as its per-student spending is moderate compared to many nearby schools. A key strength is its exceptional effectiveness in supporting vulnerable student groups, including English Learners and students with special needs, demonstrating that its success is built on strong support systems.

When compared to nearby schools, Walnut High stands out for its balanced, high performance across all metrics. It performs similarly to its district peer, Diamond Bar High, though each school has slight strengths in different subjects. It significantly outperforms schools in neighboring districts with higher poverty rates, such as Nogales High, in both academic proficiency and graduation rates. While specialized schools like International Polytechnic High may outperform in one subject, Walnut High offers more comprehensive academic strength. An area for potential growth is in mathematics, where its proficiency, while strong, is slightly below the district average.
