Summary:
Hackensack School District has one high school, Hackensack High School, serving grades 9–12 in Hackensack, with 1,813 students. The school reported a student–teacher ratio of 13.2 in 2024–25. The most important academic finding is that in 2025–26, the school was below the state result in 10 of 11 reported comparisons, matching it in the remaining comparison.
There is no second local high school to compare with it, so there is no meaningful local top or bottom school. Against state results, the school’s clearest match was Geometry, grade 9, at 50%, the same as the state. Its largest gap was in Algebra I End of Course, where 11% met the benchmark compared with 40% statewide, a 29-point difference. Results were below the state in both reported NJGPA subjects as well: ELA by 12 points and Mathematics by 14 points. These results vary by exam and grade or course, rather than pointing to a single subject advantage.
Scores declined on 10 of 11 measures available in both years, while NJGPA Mathematics rose by 14 points, from 34% to 47%; NJGPA ELA fell by 17 points, from 81% to 63%. The gap with the state did not move uniformly: it narrowed in some comparisons, including Algebra II End of Course, where the school’s gap shrank from 47 points to 19, while the NJGPA ELA gap widened from nearly even to 12 points below. SchoolDigger’s ranking also moved down, from the 30th percentile in 2023–24 to the 23rd in 2025–26, a 7-point decline. In 2024–25, 64% of students were free/reduced lunch eligible; this is context about the school, not a measure of achievement. Graduation was 1 point below the state in 2024–25, while chronic absenteeism was 4 points higher.
