Summary:
Hackettstown Public School District has one high school, Hackettstown High School, serving grades 9–12 with 868 students. Its results show a sharp split by assessment: Geometry is a clear strength, while End-of-Course Algebra I and 11th-grade science are below state results. The most important takeaway is that strong Geometry scores do not mean all math results are strong.
Hackettstown’s standout result is Geometry: proficiency was 84%, compared with 52% statewide for End of Course and 50% for 9th grade, advantages of 32 and 34 percentage points. At the other end, 11th-grade science proficiency was 18%, 10 points below the state’s 29%; End-of-Course Algebra I was 25%, 15 points below the state’s 40%. Other results were closer to state levels: 9th-grade English Language Arts was 48%, 4 points below the state, while 11th-grade NJGPA mathematics was 64%, 3 points above. As the district has only one high school in this list, these are subject-level standouts rather than comparisons between local schools.
Results changed unevenly from 2024–2025 to 2025–2026: Algebra I rose by 5 points in both reported categories, and its state-relative gap improved by 3 points in each. Geometry remained far above the state, but its scores fell by 13 points and its advantage narrowed by 9 points for End of Course and 8 points for 9th grade. Science also fell by 13 points, moving 10 points farther below the state; 9th-grade NJSLA English Language Arts fell by 9 points, and 11th-grade NJGPA English Language Arts fell by 15. SchoolDigger ranked the school 233rd of 434, in the 46th percentile with 2 stars, in 2025–2026, down from 152nd and 3 stars in 2024–2025. Other context includes an 11.7 student–teacher ratio and 30% free/reduced lunch eligible in 2024–2025; graduation was 91% versus 89% statewide, and chronic absenteeism was 12% versus 14%.
