Summary:
The high-school data for Payson CUSD 1 cover one school, Seymour High School, which serves grades 7–12 and enrolls 216 students. Since it is the only high school in the area, families can compare its results with state figures, but not with another local high school. The most important finding is that its 2025–2026 all-grades IAR mathematics proficiency was 21 points below the state, a much wider shortfall than its 4-point ELA gap.
Seymour is the sole school, so it cannot meaningfully be described as the group’s top or bottom performer. Its clearest relative strength is ELA: 53% of students were proficient, compared with 19% in mathematics; ELA was 2 points above the district result and 4 points below the state, while mathematics was 10 points below the district and 21 below the state. Results vary by grade and test: 10th-grade PreACT Secure mathematics was close to the state, at 35.5% versus 36.4%, while 9th-grade PreACT Secure ELA had a 20-point shortfall, at 41% versus 62% statewide.
Both all-grades IAR results improved from 2024–2025 to 2025–2026: ELA rose from 33% to 53%, up 19 points, and mathematics rose from 8% to 19%, up 11 points. The state-relative gaps narrowed in both subjects, though mathematics remained substantially behind. Meanwhile, SchoolDigger’s ranking fell from the 43rd percentile and 2 stars in 2023–2024 to the 29th percentile and 1 star in 2025–2026, so the ranking moved downward even as the latest IAR scores rose. Other useful context: the student–teacher ratio was 11.1 in 2024–2025, and 49% of students were free/reduced lunch eligible that year. In 2025–2026, graduation was 7 points below the state rate and dropout was 5 points higher, while chronic absenteeism was 1 point lower.
