Summary

Byron High School 9-12 serves 464 students in grades 9–12 in Byron, Illinois, among nearby schools ranging from small-town high schools to larger Rockford campuses. Its latest 11th-grade ACT results are above Illinois rates in English language arts (ELA), math and science. The clearest finding is science: the school has the strongest nearby result and is well above the state.

Science is the school’s strongest subject compared with both the state and nearby schools: 62% of students were proficient, versus 48% statewide, and its 61.6% result narrowly topped Pecatonica High School at 61.5%. Byron also exceeded state rates in ELA, 63% versus 50%, and math, 46% versus 40%; it ranked second among nearby schools in both. Ninth-grade results were especially strong, leading nearby schools in ELA and science, while tenth-grade results were more mixed: math was just 1 point above the state. The 2025–2026 graduation rate was 98%, compared with 90% statewide and 96% at Oregon Junior/Senior High School. Reported test results for Byron CUSD 226 match the school’s, so they provide no separate comparison.

Results have shifted unevenly: 11th-grade ACT ELA fell 4 points and math fell 12 points from the prior year, while ninth-grade PreACT ELA rose 11 points and math rose 13. SchoolDigger places Byron in the 80th percentile statewide for 2025–2026, rank 123 of 620, with four stars; its percentile has eased from 86 in 2023–2024. The student–teacher ratio is 11.8, the lowest among the traditional nearby high schools. The school reports 24% free/reduced lunch eligible (FRL), sy 2024–2025, the lowest supplied nearby figure for that year; Winnebago High School is next at 28%. SchoolDigger’s Special Education Students percentile rose from 46 to 76 between 2023–2024 and 2025–2026, a notable improvement in its statewide measure for that group. By contrast, its White Students percentile is 62, below the school’s overall 80.
