Belvidere School District

Belvidere School District has two schools: Belvidere Elementary School, serving prekindergarten through grade 8, and Belvidere High School, serving grades 9–12; together, they enroll 577 students. Their test results show different strengths by grade and subject, rather than a clear overall school leader. Most importantly, every listed 2025–2026 result at both schools was below its matching state result, with gaps ranging from 1 to 51 points.

Belvidere Elementary came closest to the state in grade 5 math, with 32% proficient versus 46% statewide, and grade 7 ELA, with 38% versus 56%. Its largest gap was grade 8 Algebra I: 23% versus 75%, a 51-point difference. At Belvidere High, 11th-grade NJGPA ELA was nearly even with the state at 75% versus 76%; Algebra I End of Course was the clearest concern, at 0% versus 40%. High’s grade 9 ELA result was 30% versus 51%. Because the schools serve different grades, their test scores do not support a direct school-to-school ranking.

Results over time are mixed. Elementary’s unweighted grade 3–8 ELA average rose from 16% to 25% between 2024–2025 and 2025–2026, narrowing its average gap with the state from 37 to 26 points; its math average slipped from 16% to 13%, and the gap widened from 24 to 28 points. At High, grade 11 science improved relative to the state, with the gap narrowing from 15 to 9 points, while the grade 9 ELA gap widened from 13 to 21 points. SchoolDigger’s ranking percentile declined at High from 41st to 28th over three years; Elementary rebounded from 10th to 13th in the latest year, still below its earlier 17th. In 2024–2025, student-teacher ratios were 10.7 at Elementary and 11.6 at High; free/reduced lunch eligible shares were 44% and 28%, respectively. Chronic absenteeism was above the 14% state rate at both schools: 26% at Elementary and 21% at High.
