Summary

Delta High is a public high school serving grades 9–12 in the Delta, Utah, community, with 592 students and a 21.8-to-1 student-teacher ratio in 2024–25. It is part of the Millard District, and no other schools are listed within 20 miles. The school currently ranks 23rd among 139 Utah high schools, placing it in the 83rd percentile statewide and earning four stars.

The latest academic results show a strong rebound. In 2025–26, Delta High exceeded Utah averages in all six reported ninth- and 10th-grade subject areas. Its strongest differences were in 10th-grade science, at 57.8% compared with 39.3% statewide, and 10th-grade English language arts, at 66.1% compared with 48.2%. Tenth-grade results improved substantially from the prior year in all three subjects, although mathematics remains the clearest opportunity: 39.3% met expectations compared with 47.7% in the Millard District. The school’s overall ranking also rose from 72nd to 23rd, but families may want to watch whether these gains continue over time.

Student outcomes beyond testing are encouraging. The 2024–25 graduation rate was 92.8%, above Utah’s 89.8% but below the Millard District rate of 95.4%. The dropout rate was 4.0%, well below the state’s 8.5%, while chronic absenteeism was just 6.6%, compared with 23.8% statewide. The school also ranked especially well for students from low-income households, placing 14th of 97 Utah schools. Key areas to monitor are mathematics, the remaining gap with district averages, and the gradual rise in the student-teacher ratio.
