Summary:
ZIP code 67661 has one high school, Phillipsburg High, serving grades 9–12 with 173 students. With no other local high school to compare it with, families can look to state results and the school’s changes over time for context. The most important academic finding is that all-grades ELA and science proficiency are well below state rates, while math is close to the state result.
Phillipsburg High is both the highest- and lowest-scoring school in this ZIP-code list because it is the only one. In 2025–26, its all-grades proficiency was 34% in ELA, 40% in math, and 27% in science, compared with state rates of 46%, 41%, and 38%, respectively. That puts the school 12 points below the state in ELA, 1 point below in math, and 11 points below in science. A brighter spot is 10th-grade math: 40% proficiency, 4 points above the state rate; 10th-grade ELA was 7 points below. Because there is only one school in the area, these figures cannot show differences among local schools.
Results have shifted in different directions by subject. From 2024–25 to 2025–26, the school’s ELA proficiency fell 7 points to 34%, while the state rate rose 1 point to 46%, widening the school’s shortfall by 9 points. School math slipped 1 point to 40% as the state rose 2 points, changing the school’s position from 3 points above the state to 1 point below. SchoolDigger’s ranking also declined, from the 84th percentile in 2023–24 to the 44th in 2025–26, while its rating fell from 4 stars to 2; the number of schools ranked changed over that period. Other measures present a mixed picture: the 2023–24 graduation rate was 95%, 6 points above the state, while 2025–26 chronic absenteeism was 22%, 4 points above the state. The reported student-teacher ratio was 8.5, and the free/reduced-lunch rate was 43%.
