Summary:
Yuma Union High School District has eight high schools serving grades 9–12, with results that vary by school but are generally well below state proficiency levels. Across the six schools reporting 2025–26 results, average proficiency was 21% in English language arts (ELA) and 12% in math, compared with 41% and 33% statewide; the four reported science results averaged 7%, versus 19% statewide. The most important finding is that reported proficiency is substantially below state levels across all three subjects.
Cibola High School leads the reported ELA and math results, with 28% and 18% proficient; Yuma High School is lowest at 10% and 5%, respectively. That is an 18-point ELA gap and a 13-point math gap between the two schools. SchoolDigger’s recent statewide percentiles also place Cibola highest among the six ranked schools, at the 29th percentile, and Yuma lowest, at the 5th. In science, Gila Ridge High School and Kofa High School tie at 8%, while San Luis High School reports 3%. Graduation results show a different contrast: San Luis reports 98%, while Vista High School reports 76%; the six-school average is 92%, above the state’s 80%.
SchoolDigger’s rankings show some changes in relative standing, but they do not establish changes in test scores. Among five schools ranked in each of the last three years, the average percentile rose from 14 in 2023–24 to 17 in 2025–26; San Luis climbed from the 4th to the 21st percentile, while Gila Ridge fell from the 30th to the 17th. Staffing figures do not simply track proficiency: student–teacher ratios range from 21.0 at Yuma to 25.8 at San Luis, and Yuma is the lower-scoring school. Yuma Online Distance Academy reports a 19% dropout rate versus 5% statewide. Some proficiency results are suppressed, and ranking changes are not test-score trends.
