Summary:
Zip code 62340 has two schools in Griggsville-Perry CUSD 4: Griggsville-Perry Primary School, serving prekindergarten through grade 4, and Griggsville-Perry High School, serving grades 9–12. They enroll 148 and 89 students, respectively. The clearest academic strength in the area is Primary math: in 2025–2026, its all-grades result was 54%, 14 percentage points above the state, and its third-grade result was 68%, 19 points above the state.
The Primary stands out most in math, but its ELA results vary by grade: all-grades ELA was 54%, 3 points below the state, while third-grade ELA was 52%, 4 points above. The High School also has a mixed profile. Its ninth-grade PreACT Secure ELA result was 68%, 7 points above the state, and 11th-grade ACT science was 52%, 4 points above; 11th-grade ACT ELA was 48%, 2 points below. Graduation is a weaker result: 84% compared with 90% statewide, a 6-point shortfall. Because the schools serve different grades and use different assessments, their test scores cannot be ranked directly against one another.
Results improved on the matched tests over time, especially High School ACT science, which rose 32 percentage points, from 20% in 2024–2025 to 52% in 2025–2026; ninth-grade PreACT Secure ELA rose 16 points, from 53% to 68%. Primary all-grades math increased 17 points, from 37% to 54%. SchoolDigger rankings moved in opposite directions: the Primary fell from the 72nd to the 45th percentile and from four stars to two, while the High School rose from the 14th to the 68th percentile and from one star to three. In 2024–2025, the Primary had a 9.3 student-teacher ratio and 31% free/reduced lunch eligible; the High School’s figures were 10.7 and 43%. These are contextual differences, not explanations for the test results. Chronic absenteeism also contrasts: in 2025–2026 it was 18% at the Primary, below the state’s 24%, and 27% at the High School, above it.
