Summary:
The four high schools in Buckeye Union High School District serve grades 9–12, with enrollments ranging from 121 to 2,096 students. In 2025–26, the schools averaged 30% proficiency in English language arts (ELA), compared with 41% statewide, and 27% in math, compared with 33% statewide. Graduation is a stronger comparison: the schools averaged 92% in 2024–25, versus 80% statewide, and every school was above the state rate. The most important academic finding is that the district’s schools averaged below the state in both tested subjects, with a smaller shortfall in math than in ELA.
Estrella Foothills High School leads the group across the reported academic measures: 37% in ELA, 31% in math and 13% in grade 11 science, as well as the highest graduation rate, 95%. Its ELA result is 12 percentage points above the group low at Buckeye Union High School; its math result is 13 points above the low at BUHSD Institute of Online Learning. The Institute’s ELA rate is 29%, but its math rate is 18%—13 points below the next-lowest school, Buckeye Union, at 28%. Graduation rates range from 86% at the Institute to Estrella’s 95%; all four schools exceed the state rate.
SchoolDigger’s latest rankings place Estrella highest among these schools, at the 48th percentile, and the Institute lowest, at the 30th percentile; all four have two stars. The group’s average ranking percentile rose from 34 in 2023–24 to 40 in 2025–26, but schools moved in different directions: Youngker gained 9 points, Buckeye Union 11 and the Institute 10, while Estrella fell 4. School size and teacher ratios do not neatly track results: Youngker has the largest enrollment and highest reported ratio, 24.3 students per teacher, while Estrella leads with a similar ratio of 23.7; Buckeye Union’s ratio is 22.5 despite its lowest ELA result. Test-score trends are unavailable, and lunch data and the Institute’s teacher ratio are not reported.
