North Haledon School District

North Haledon School District has two schools serving prekindergarten through grade 8: Memorial Elementary School serves prekindergarten–grade 4, and High Mountain School serves grades 5–8. Their enrollments are 349 and 259, respectively. In 2025–2026, results were generally stronger than state averages in ELA and math, while science at High Mountain was below the state in both tested grades. The most important takeaway is that ELA and math strengths vary by grade, and science is the clearest area of concern.

Memorial stood out for being above the state in all four of its reported ELA and math results: for example, grade 3 ELA was 59% versus 48% statewide, an 11-point advantage, and grade 3 math was 57% versus 49%, an 8-point advantage. High Mountain had its strongest relative results in grade 8 math, at 64% versus 23% statewide, a 41-point lead, and grade 6 ELA, at 65% versus 51%, a 14-point lead. Its weaker results were in science: grade 5 was 24% versus 27% statewide, and grade 8 was 17% versus 19%. These are grade-specific comparisons, not a direct contest between schools serving different grades.

Results relative to the state improved in three of Memorial’s four comparable results from 2024–2025 to 2025–2026, including a 14-point improvement in the grade 3 math gap; its grade 4 math advantage narrowed by 4 points. High Mountain had a mixed pattern: its grade 7 math gap improved by 16 points, while its grade 8 math lead narrowed by 5 points. SchoolDigger’s 2025–2026 ranking was higher for High Mountain—74th percentile and four stars, compared with Memorial’s 58th percentile and three stars—though Memorial’s percentile rose from 40th in 2023–2024. In 2024–2025, free/reduced lunch eligible students made up 26% at Memorial and 24% at High Mountain; student–teacher ratios were 10.2 and 10.4. Chronic absenteeism was 11% at Memorial and 8% at High Mountain.
