Summary

Triad High School in Troy, Illinois, serves grades 9–12 and enrolls 1,218 students, making it a middle-sized school among nearby high schools. Its 2025–2026 graduation rate was 98%, and chronic absenteeism was 5%, both the best reported figures among nearby schools with data. The most important finding is that Triad’s results are strong across subjects: it led nearby schools in all three 11th-grade ACT subjects and scored well above state rates.

Triad’s 11th-grade ACT proficiency was 74% in English language arts, 67% in math and 75% in science, compared with state rates of 50%, 40% and 48%. Its nearest competitor, Edwardsville High School, scored 66%, 57% and 66% in those subjects. The Triad CUSD 2 results matched the school’s, so the district figures show no separate advantage. Triad was also first or second among nearby schools in every reported grade 9 and 10 PreACT Secure subject, and all six results topped state rates. Its graduation rate of 98% exceeded the state’s 90%; its 5% chronic absenteeism was far below the state’s 24% and the next-lowest nearby rate, 16% at Wesclin Senior High School. No tested 11th-grade ACT subject stands out as a weakness against nearby schools.

Recent results remain high, though some have dipped: grade 9 PreACT English fell 7 points and grade 10 math fell 4 points from the prior comparable year, while 11th-grade ACT math rose 4 points. SchoolDigger ranks Triad 59th of 620 Illinois schools, at the 90th percentile with 5 stars; its percentile has fluctuated between 87 and 93 in recent reported years. In 2024–2025, its student-teacher ratio was 16.2, around the middle of nearby schools, and 16% of students were free/reduced lunch eligible—the lowest nearby rate for that year. SchoolDigger’s statewide rankings also show lower relative standing in how well the school serves Special Education Students, at the 63rd percentile versus 90 overall; its Multi-racial Students ranking fell from the 85th percentile in 2023–2024 to the 52nd in 2024–2025.
