HADDON HEIGHTS School District

HADDON HEIGHTS School District has four schools serving 1,457 students from prekindergarten through grade 12: three elementary schools spanning PK–6 and a junior/senior high school serving grades 7–12. The latest test results are broadly favorable at the two tested elementary schools, while the high school’s results vary more by grade and subject. The most concerning result is the high school’s grade 8 NJSLA math score: 3%, compared with 23% statewide.

Glenview Avenue is the strongest overall of the two elementary schools with test results: it leads in five of eight same-grade ELA and math comparisons, and its eight scores average 66%, versus 62% at Seventh Avenue. Both schools exceed state results in seven of those eight comparisons; Seventh’s grade 5 ELA score, 50%, is the exception, at 2 points below the state. Seventh stands out in grade 3 and 4 ELA and grade 6 math. The schools’ biggest gaps are in grade 5: Glenview leads by 19 points in ELA and 19 points in math. The high school has several strong results—including ELA in grades 7–9, grade 7 math, science, and NJGPA—but its grade 8 math result is 20 points below the state.

Results changed in different directions over time: the elementary schools’ average ELA score rose 8 points from 2024–25 to 2025–26, while grade 5 science fell by 14 points at Glenview and 18 points at Seventh. High school grade 8 math fell 27 points year over year, while grade 7 math remained 20 points above the state. SchoolDigger’s percentile rankings rose from 73 to 79 at Glenview, 66 to 71 at Seventh, and 55 to 63 at the high school. In 2024–25, free/reduced lunch eligible shares were 8% at Glenview, 9% at Seventh and Atlantic, and 26% at the high school; student-teacher ratios were 8.6 at Glenview and 11.4 at Seventh and the high school. These measures offer context, not an explanation for test results; Atlantic Avenue serves PK–2 and has no test results in the grades reported.
