Summary:
Schools in ZIP code 08004 include four schools serving children from early childhood and elementary grades through middle and high school, with 2,567 students enrolled across the area. The clearest contrast is in 2025–2026 Algebra I End of Course results: Winslow Township Middle School scored 44%, 4 points above the state, while Winslow Township High School scored 13%, 27 points below it—a 32-point difference between the schools.
Winslow Township Middle School has a notable Algebra I result, but its regular-grade math scores were much lower: seventh-grade math was 15% versus 38% statewide, and eighth-grade math was 5% versus 23%. The high school’s standout is 10th-grade Geometry, at 29% compared with 13% statewide, 16 points higher. Most other reported results fall below state comparisons: 14 of 16 non-suppressed school-and-state comparisons were below state. The test data cover only the middle and high schools, so the elementary schools cannot be compared on proficiency.
Middle-school ELA results improved from 2024–2025 to 2025–2026: seventh grade rose 10 points and eighth grade rose 3, while state results declined in both grades. High-school ELA also improved on ninth-grade testing and the NJGPA; the NJGPA ELA gap narrowed to 5 points below state, compared with a 15-point gap in math. SchoolDigger’s 2025–2026 statewide rankings put the high school at the 27th percentile and the middle school at the 20th. Student–teacher ratios are similar, from 11.6 at the high school to 11.8 at the middle school. Both report about 61% free/reduced lunch eligible for 2024–2025; this is context, not an explanation for the score differences. The two elementary schools, Thomas Richards Early Childhood Center and Atco Elementary School, have no test results in the supplied data.
