Summary:
Harrison High School is the only high school listed in Harrison Public Schools, serving grades 9–12 with 795 students; with no other listed high schools, there is no local school-to-school comparison. The clearest concern is that all six 2025–26 test results with numeric school scores were below New Jersey’s results.
Within the available scores, 11th-grade NJGPA English Language Arts was closest to the state: 61% proficient at Harrison versus 76% statewide, a 15-point gap. Algebra I End of Course was farthest behind, at 5% versus 40%, a 35-point gap. The other results were also below state figures, including 9th-grade English Language Arts at 28% versus 51%, and 11th-grade NJGPA mathematics at 36% versus 61%. Harrison’s chronic absenteeism is a relative bright spot: 5% in 2024–25, compared with 14% statewide. Its graduation rate was 87%, versus 89% statewide.
Results and SchoolDigger’s ranking both moved downward in the reported years. Across six matching tests, Harrison’s 11th-grade NJGPA English Language Arts score fell 17 points, from 78% in 2024–25 to 61% in 2025–26; the state score fell 5 points, from 81% to 76%. SchoolDigger ranked Harrison at the 34th percentile in 2023–24, the 26th in 2024–25, and the 12th in 2025–26, when it received 1 star. As context, 90% of students were free/reduced lunch eligible in 2024–25, and the student–teacher ratio was 15.9 to 1.
