Summary:
The three schools listed for Mokena School District 159 serve students from prekindergarten through grade 8 and enroll 1,557 students. SchoolDigger gives the district 4 stars and ranks it 148th of 738 districts, in the 80th percentile. In 2025–2026, all three schools scored above the state in both all-grades English Language Arts (ELA) and mathematics: their results ranged from 65% to 82% in ELA, compared with 56% statewide, and from 58% to 73% in math, compared with 40% statewide. Most importantly, every school’s results were above the state in both subjects.
Mokena Junior High School stands out in ELA, while Mokena Elementary School leads in math. Junior High’s ELA score was 82%, versus 70% at Elementary and 65% at Mokena Intermediate School; Junior High was 14 points above the other two schools’ average. Elementary led math with 73%, compared with 57.7% at Junior High and 57.5% at Intermediate, a 15-point advantage over those schools’ average. Intermediate had the lowest ELA result, 10 points below the other schools’ average, and the lowest math result, 8 points below their average. These all-grades results cover different grade spans, so they are not same-grade comparisons.
Recent changes vary by school: from 2024–2025 to 2025–2026, Elementary gained 7 points in ELA and 6 in math, while Intermediate fell 4 and 8 points, respectively. Junior High gained 5 points in ELA but declined 2 in math. Intermediate’s fifth-grade science score, however, rose 17 points. SchoolDigger’s statewide percentile rank also fell for Junior High, from 92 in 2023–2024 to 87 in 2025–2026, and for Intermediate, from 84 to 72. Staffing and income figures offer context, not an explanation for results: 2024–2025 student-teacher ratios ranged from 12.2 at Junior High to 16.4 at Elementary; free/reduced lunch eligible rates that year were 17% at Junior High, 19% at Intermediate, and 20% at Elementary.
