Summary:
High schools in North Greene CUSD 3 consist of one school, North Greene Junior/Senior High School, serving grades 7–12 with 369 students. Most importantly, all 15 reported, comparable, non-suppressed 2025–2026 test results were below the state figures.
There is no other local high school to rank above or below it. Compared with the state, its closest results were 7th-grade IAR math, at 34% proficient versus 40% statewide, and 9th-grade PreACT Secure science, at 41% versus 47%—each about 6 percentage points lower. The largest gaps were in 8th-grade ISA science, 28% versus 52%, and 10th-grade PreACT science, 24% versus 48%; both were 24 points below the state. The 10th-grade PreACT Secure ELA result was also notably lower, at 31% versus 54%, a 23-point gap. The 8th-grade IAR math result is suppressed, so it cannot be compared.
Recent trends differ by subject: IAR math improved, while ELA slipped. From 2024–2025 to 2025–2026, the school’s all-grades math result rose from 17% to 23%, while the state result went from 39% to 40%; the gap narrowed by 5 points. All-grades ELA fell from 40% to 39% as the state rose from 53% to 56%, widening the gap by 4 points. Eighth-grade ISA science also dropped from 43% to 28%, while the state increased from 45% to 52%. SchoolDigger’s statewide percentile rose from 19 in 2023–2024 to 32 in 2024–2025, then fell to 22 in 2025–2026. The school’s student–teacher ratio was 11.1:1 in 2024–2025, and 50% of students were free/reduced lunch eligible that year; these are context, not evidence of what explains the results.
