Summary:
The ORANGE BOARD OF EDUCATION School District in Orange, New Jersey, includes 11 schools—seven elementary, two middle and two high schools—with reported enrollment of 5,332, serving children from early elementary through high school. The starkest difference is between the high schools: in 2025–2026, STEM Innovation Academy of the Oranges scored 98% in grade 9 ELA, compared with 20% at Orange High School, a 78-point gap; STEM also led by 70 points in grade 11 science. This wide gap between the two high schools is the most important finding for families comparing local options.
Among elementary schools, Heywood Avenue Elementary School had the strongest grade 3–7 averages in 2025–2026: 41% in both ELA and math. Oakwood Avenue Community School was lowest, at 21% in ELA and 14% in math—gaps of 20 and 27 points, respectively. Results vary by grade: Cleveland Street Elementary School reached 67% in grade 7 ELA and 58% in math, exceeding state results by 11 and 20 points. At middle school, Orange Preparatory Academy School of Inquiry and Innovation scored 100% in grade 8 Algebra I, 26 points above the state, but was below state results in grade 8 ELA and science.
Recent elementary trends differ by subject: the seven-school ELA average fell from 38% to 32% between 2024–2025 and 2025–2026, while math rose from 23% to 27%; grade 5 science rose from 10% to 15%. SchoolDigger’s statewide percentile ranking for STEM moved from 97th to 86th to 98th across the last three ranking years, while Orange High’s was 10th, 8th and 12th. School context measures do not follow a simple pattern with scores: Cleveland and Oakwood had similar free/reduced lunch eligible shares in 2024–2025—75% and 75%—but notably different results; their student-teacher ratios were 8.2 and 9.7. Heywood’s ratio was 11.7, alongside the top elementary averages. Central Elementary serves K–2, but no test scores are supplied for it.
