Summary:

The William S. Hart Union High district consists of 16 schools serving grades 7-12 in the Santa Clarita Valley, ranking in the state's top 15% overall.

Parents will find several standout schools, with Academy of the Canyons and West Ranch High consistently achieving top state rankings and exceptional test scores, while Rancho Pico Junior High leads among middle schools. In contrast, Bowman (Jereann) High (Continuation) faces significant challenges, and Golden Valley High shows notable academic performance gaps despite a good graduation rate.

The district excels in English (70% proficient vs. 49% state average) but has a district-wide opportunity in math, where only three schools exceed 50% proficiency. Chronic absenteeism varies widely, from under 2% at the top schools to over 68% at the continuation school. Most comprehensive high schools like Valencia High and Saugus High perform well above state averages, demonstrating the area's generally strong educational offerings.
