Summary:
The 08865 list includes 10 schools—seven elementary, two middle and one high school—serving students from early childhood through high school. Eight schools have test-score records; the Early Childhood Learning Center and Philipsburg Primary School do not. Across grades 3–8, average school results were 45% in ELA and 35% in math, about 6 percentage points below state averages of 51% and 40%. The clearest takeaway is that schools serving the same grade can have sharply different results: grade 8 scores span 43 points in ELA and 48 points in math.
Lopatcong Township Middle School is the strongest broad academic performer in the supplied results: it led in grade 8 with 73% in ELA and 51% in math, compared with state results of 53% and 23%. At the other end, Phillipsburg Middle School had 30% in grade 8 ELA and 3% in math. Standouts also vary by subject: Harmony Township School led grade 8 science at 50%, versus 19% statewide, while Lopatcong Elementary School led grade 3 ELA and math at 52% and 61%. These stronger results do not carry across every school or subject.
Recent changes are more encouraging in ELA than math: matched school ELA scores rose an average of 3 points from 2024–2025 to 2025–2026 while state scores fell about 3 points, narrowing the gap by about 5 points; math was essentially flat as state results edged up, so the relative gap widened by less than 1 point. SchoolDigger ranks Lopatcong Township Middle School in the 78th percentile statewide and Lopatcong Elementary School in the 53rd; the elementary school’s percentile rank rose 18 points from 2023–2024. Context differs too: free/reduced lunch eligible shares in 2024–2025 ranged from 17% at Lopatcong Middle to 77% at Phillipsburg Elementary School. Phillipsburg High School had a 90% graduation rate, above the state’s 89%, but chronic absenteeism was 23%, versus 14% statewide, and several test results were below state levels.
