High Schools in Phillipsburg

Phillipsburg has one high school, Phillipsburg High, serving grades 9–12 and enrolling 173 students. Its strongest test result is mathematics, close to the state average, while ELA and science proficiency are considerably lower. The most important takeaway is that the school’s academic results vary sharply by subject, with ELA and science the clearest areas of concern.

Because it is the only high school listed in the area, Phillipsburg High cannot be compared with another local high school. In 2025–26, 40% of students were proficient in mathematics, just 1 percentage point below the state; ELA proficiency was 34%, 12 points below the state, and science was 27%, 11 points below. The school’s 2023–24 graduation rate was a bright spot at 95%, 6 points above the state and equal to the Phillipsburg district. Attendance was less favorable: chronic absenteeism was 22%, 4 points above the state and 8 points above the district.

Recent results and SchoolDigger rankings point to declining relative standing, though the measures show different things. From 2024–25 to 2025–26, ELA proficiency fell 7 points while the state rose 1 point, widening the school’s gap by 9 points; mathematics fell 1 point while the state rose 2, moving the school from 3 points above the state to 1 point below. SchoolDigger’s ranking also slipped from 50th of 318 schools, at the 84th percentile with 4 stars, in 2023–24 to 191st of 340, at the 44th percentile with 2 stars, in 2025–26. The school’s student–teacher ratio is 8.5, and its free/reduced-lunch rate was 43% in 2024–25; these are context measures, not explanations for its results. With only one school listed, local school-to-school comparisons are not available, and the statewide ranking counts changed over time.
