Summary

Willow Grove Elementary School in Hackettstown, NJ, serves grades 2–4 and enrolls 320 students. Its latest results show an uneven picture: fourth-grade ELA is a clear strength, but third-grade ELA and math in both tested grades lag nearby schools. The most important finding for parents is that the school’s math results are weak compared with nearby schools in both third and fourth grade.

Fourth-grade ELA is the strongest result: 56% of students were proficient, above the state’s 46%, though below the nearby-school average of 61%. Third-grade ELA was 42%, below the state’s 48% and the nearby average of 58%. Math also fell short of nearby schools: third-grade proficiency was 47% versus a nearby average of 59%, and fourth-grade proficiency was 48% versus 59%. In all four grade-and-subject comparisons, only Netcong Elementary School scored lower among the nearby schools with results for the same grade. Willow Grove’s math was also below the state in third grade, by 2 percentage points, while fourth-grade math was 1 point above it. Scores listed for the Hackettstown Public School District match the school’s results exactly.

Math has declined over the four years shown: third-grade proficiency fell 6 percentage points and fourth-grade proficiency fell 12 points from 2022–23 to 2025–26. Over that span, fourth-grade ELA rose 1 point, while third-grade ELA fell 4 points. SchoolDigger rates Willow Grove at the 50th percentile, rank 664 of 1,331, with 3 stars; its percentile has fallen 30 points since 2018–19, when it had 4 stars. Context includes a student-teacher ratio of 8.8 in 2024–25 and 45% of students eligible for free/reduced lunch in 2024–25, the second-highest rate among nearby schools with that measure. SchoolDigger’s statewide standing for Low Socio Economic Status Students is 65th percentile, above the school’s overall 50th; its Female Students standing fell from the 63rd percentile in 2023–24 to the 41st in 2025–26.
