Summary:
ZIP code 07621 has one high school, Bergenfield High School, serving grades 9–12 and enrolling 1,239 students. Its 2025–26 results were above New Jersey’s on five of six reported test comparisons, with an average margin of 4 percentage points; the clearest exception was Algebra I End of Course, 13 points below the state.
There is no meaningful top-versus-bottom comparison among local schools because Bergenfield is the only one listed. Its strongest state comparisons were NJGPA mathematics, with 72% proficient versus 61% statewide, an 11-point lead, and grade 11 science, with 37% versus 29%, a 9-point lead. NJGPA English language arts was also higher: 83% versus 76%, an 8-point lead. In contrast, Algebra I End of Course was 27% proficient versus 40% statewide; grade 9 Algebra I was 27% versus 22%, 5 points above the state. Other outcomes were favorable for graduation (95% versus 89% statewide) and dropout (about 0% versus 1%), while chronic absenteeism was 15%, slightly above the state’s 14%.
The matched-test average margin over the state grew from 3 points in 2024–25 to 4 points in 2025–26, but subjects moved in different directions: Algebra I End of Course and science improved relative to state results, while the school’s grade 9 English lead narrowed from 11 points to 4, and its NJGPA math lead narrowed from 17 points to 11. SchoolDigger gives the school four stars and ranks it 83rd of 434 New Jersey high schools for 2025–26, up from 165th of 429 in 2023–24. Its 11.7:1 student-teacher ratio and 39% free/reduced lunch eligible in 2024–25 describe school context, not a basis for explaining results. Because this is the only school in the ZIP-code list, there are no local peer comparisons.
