Johnsburg Junior High School up 304 spots statewide this year
Summary:

Johnsburg CUSD 12 has four schools serving students from the primary and elementary years through junior high and high school. The supplied data include test results for three schools, but none for Ringwood School Primary Center; because grade levels and assessments differ, not every school can be fairly compared on test scores. The clearest overall finding is a split by subject and school level: junior-high ELA is above the state, while elementary math—especially fourth grade—is below it.

In the strongest direct school-to-school comparison, Johnsburg Junior High School leads Johnsburg Elementary School on 2025–26 all-grades IAR: 61% versus 52% in ELA, a 9-point lead, and 37% versus 32% in math, a 5-point lead. Junior-high ELA is 5 points above the state; its math is 3 points below. Elementary ELA is 4 points below the state, and its math is 8 points below. The elementary school’s most pronounced shortfall is fourth-grade math: 23% proficient versus 42% statewide, a gap of 19 points. Johnsburg High School stands out on 2025–26 11th-grade ACT, exceeding the state by 8 points in ELA, 5 in math and 12 in science. Its counterpoint is ninth-grade PreACT science, 35% versus 47% statewide, 12 points lower; tenth-grade PreACT science is 8 points above the state.

Recent trends are mixed rather than consistent across subjects. From 2024–25 to 2025–26, all-grades ELA rose at both IAR schools: by 7 points at the elementary school and 23 at the junior high. Math diverged: it fell 9 points at the elementary school and rose 12 at the junior high. SchoolDigger ranks the district 422nd of 738, in the 43rd percentile, with 2 stars; its school rankings show the elementary school falling from the 61st to the 37th percentile, while the high school moved from the 70th to the 66th and the junior high from the 48th to the 47th. Class-size context is similar, with student-teacher ratios ranging from 13.2 to 14.8. In school year 2024–25, free/reduced lunch eligible shares ranged from 31% to 38%; these figures are context, not an explanation for results.
