Summary:
Glen Rock Public School District has one listed high school, Glen Rock High School, serving grades 9–12, with 722 students and 10 students per teacher in 2024–2025. With no other high school in the list, there is no school-to-school comparison; the clearest overall finding is that the school was above the state in every reportable 2025–2026 test result.
Glen Rock High School stands out most in Algebra II and English Language Arts: ninth-grade Algebra II proficiency was 84%, 31 percentage points above the state’s 53%, while ninth-grade English Language Arts was 80%, 28 points above the state’s 51%. The clearest exception is Algebra I at end of course, where the school’s 40.3% result was just 0.4 points above the state’s 39.9%. Its state-relative lead is therefore substantial on most reported tests, but much narrower on this Algebra I result.
Results moved in different directions over time: ninth-grade English Language Arts rose 9 points and Algebra I rose 8 points from 2024–2025 to 2025–2026, while grade 11 science and ninth-grade Geometry each fell about 10 points. SchoolDigger’s ranking also slipped, from 37th of 429 schools (91st percentile) in 2023–2024 to 51st of 434 (88th percentile) in 2025–2026. Other 2024–2025 measures were favorable against the state: chronic absenteeism was 3% versus 14%, and graduation was 90% versus 89%. The school reported 1% free/reduced lunch eligible in 2024–2025; this is context, not an explanation for results.
