Summary

Kelvin Grove Junior High School serves 260 students in grades 4–8 in Lockport, Illinois. Its 2025–2026 English language arts results were well above state levels, but performance varies by grade and subject. The most important concern is eighth-grade math: 28% of students were proficient, 6 points below the state and seventh among 10 nearby schools with results.

ELA is the school’s strongest subject overall: 75% of students were proficient, 18 points above the state and 1 point above Lockport School District 91. In math, 47% were proficient—7 points above the state but 2 points below the district. Among nearby schools, Kelvin Grove ranked sixth in both subjects; its results were 6 points above the nearby average in ELA and 3 points above it in math. Sixth grade is a bright spot, with 83% proficient in ELA and 56% in math; eighth-grade ELA was 70%, still 7 points above the state. Nearby schools serve different grade spans, so grade-level comparisons offer a more direct reference.

Results have improved since 2023–2024, though both subjects fell from their 2024–2025 highs: ELA rose from 62% to 75% overall, while math increased from 37% to 47%, with a 9-point drop in math in the latest year. SchoolDigger ranks Kelvin Grove 316th of 1,126 schools, at the 72nd percentile with 4 stars. Its 2024–2025 student-teacher ratio was 8.6, the lowest among nearby schools, and 37% of students were free/reduced lunch eligible that year. SchoolDigger’s statewide ranking for Low Socio Economic Status Students rose from the 68th percentile in 2023–2024 to the 92nd in 2024–2025, then stood at the 81st percentile in 2025–2026—9 points above the school’s overall percentile that year.
