Summary:
Zip code 07028 has five Glen Ridge Public School District schools serving 1,746 students from prekindergarten through grade 12: four elementary schools and one high school. Only Ridgewood Avenue School and Glen Ridge High School have test results in the data, and both are above state results on every reported test. Across the reported results, schools average 30 points above the state in ELA, 35 in math, and 26 in science—the clearest area-wide finding is consistently strong performance relative to state benchmarks.
Ridgewood Avenue stands out for grade 5, with results 44 points above the state in math and 37 points above in ELA; its smallest listed advantage is 18 points in grade 6 ELA. At Glen Ridge High, the largest listed margins are 40 points in grade 7 math and 38 points in grade 8 ELA. There is no fair same-grade academic ranking between the two, and the other three schools have no test results here. For attendance, Central School is lowest at 1% chronic absenteeism, while the high school is highest at 10%; even that high-school rate is below the state’s 14%.
Recent trends are mixed: average ELA margins over the state rose from 27 to 30 points between 2024–25 and 2025–26, while math margins narrowed from 42 to 35 points; science remained about 26 points above the state. SchoolDigger gives both tested schools five stars, but their rankings moved in different directions: the high school rose from 43rd to 20th, while Ridgewood shifted from 28th to 76th. Staffing figures also vary: the student-teacher ratio is 10.8 at the high school and 17.8 at Central. Because the tested schools serve different grade spans, these figures do not establish which is academically stronger for the same grade or test.
