Summary:
The Jefferson Township Public School District has five schools serving 2,406 students: three elementary schools, an intermediate school serving grades 4–8, and a high school serving grades 9–12. The central takeaway is that results vary sharply by school, grade and test, rather than showing one consistent level of performance across the district.
Among the elementary schools with comparable 2025–2026 third-grade results, White Rock Elementary School stands out above Arthur Stanlick Elementary School: White Rock scored 49% in ELA and 53% in math, compared with Stanlick’s 36% and 33%, gaps of 13 and 21 percentage points. White Rock was also slightly above state results in both subjects, while Stanlick was below by 12 points in ELA and 17 in math. The Intermediate School was notably strong in eighth grade—64% in ELA and 31% in math, both above state results—but seventh-grade math was 28%, 10 points below the state. At the High School, 11th-grade NJGPA ELA was a strength at 88%, 13 points above the state; Algebra I was a clear weak spot at 12%, 28 points below.
Recent elementary results were weaker relative to the state than the previous year’s: Stanlick’s third-grade margins shifted from 3 points above the state in 2024–2025 to 12 points below in ELA and 17 below in math in 2025–2026; White Rock remained above the state, but its leads narrowed. SchoolDigger ranks the district 367th of 607 districts (40th percentile, two stars); its recent school percentiles also declined from 2023–2024 to 2025–2026, including White Rock from 64 to 53 and Stanlick from 28 to 25. As context, 2024–2025 free/reduced lunch eligibility was 15% at White Rock and 21% at Stanlick; their student-teacher ratios were 11.9 and 11.5. These are observations, not explanations of test results. Year-to-year test comparisons involve different student cohorts, and no test scores are supplied for Ellen T. Briggs Elementary School.
