Summary:
High schools in ZIP code 73669 consist of one school, Thomas-Fay-Custer Unified High School, which serves grades 10–12 and enrolls 105 students. With no other high school in the list, families can compare its results with state figures but not with another local school; the most important finding is that proficiency fell in all four reported subjects from 2024–2025 to 2025–2026 while state rates changed little.
Thomas-Fay-Custer stands out positively in English Language Arts I and U.S. History, but Science is its clearest weakness. In 2025–2026, 42% were proficient in English Language Arts I, 16 points above the state rate of 26%; U.S. History was 44%, 3 points above the state’s 41%. Mathematics proficiency was 17%, 8 points below the state’s 25%, while Science was 14%, 16 points below the state’s 30%—the largest shortfall. The 11th-grade comparisons showed a similar pattern: 6 points above the state in English Language Arts I, level in Mathematics, 7 points below in Science, and 3 points above in U.S. History.
The recent direction is concerning: school proficiency fell 12 points in English Language Arts I, 26 in Mathematics, 13 in Science, and 7 in U.S. History between the two years, while state rates shifted by no more than 1 point in each subject. SchoolDigger’s statewide ranking also dropped, from 46th of 463 schools, in the 90th percentile with 5 stars, in 2024–2025 to 170th of 462, in the 63rd percentile with 3 stars, in 2025–2026. Other measures offer context: the graduation rate was 81% in 2024–2025, 3 points above the state, and chronic absenteeism was 10% in 2025–2026, 6 points below the state. The school’s student-teacher ratio was 11.7:1, and 42% were free/reduced lunch eligible in 2024–2025; these figures describe the school, but do not explain its results.
