Summary:
Delaware Valley Regional High School District has one listed high school, Delaware Valley Regional High School, serving grades 9–12 with 705 students. Its 2025–26 results were stronger than New Jersey’s in several English and Geometry assessments, but the clearest finding is a sharp contrast between those strengths and a substantial Algebra I End-of-Course shortfall.
There is no school-to-school leader or trailing school in this one-school list; compared with the state, English and Geometry were the strongest areas. The school was 13 percentage points above New Jersey in both 9th-grade English Language Arts (65% versus 51%) and 11th-grade NJGPA English Language Arts (89% versus 76%). Geometry was also above the state: 12 points for End of Course (63% versus 52%) and 15 points for grade 9 (65% versus 50%). By contrast, Algebra I End of Course was 19 points below the state (21% versus 40%). The separate grade-9 Algebra I result was much closer, just 1 point below (21% versus 22%). Science was 12 points above the state, and 11th-grade NJGPA Mathematics was 5 points above.
Relative standing improved over time, though not every subject followed that pattern: across eight matched tests, the average school-versus-state gap moved from about even in 2024–25 to 6 points above the state in 2025–26. NJGPA Mathematics proficiency fell from 69% to 66%, while the school’s advantage over the state narrowed from 11 points to 5; Algebra I proficiency rose, but End-of-Course results remained well below the state. SchoolDigger’s ranking improved from 197th of 429 schools in 2023–24 to 122nd of 434 in 2025–26; its current district rank is 189th of 607, with 3 stars. In 2024–25, graduation was 92%, dropout 0.5%, and chronic absenteeism 10%; the student-teacher ratio was 12:1, and the school reported 13% free/reduced lunch eligible. Because only one school is listed, these figures cannot show how schools compare within the district or explain differences in results.
