Best High Schools in Edison, NJ

Edison, New Jersey, has three high schools serving grades 9–12, with 5,253 students combined: John P. Stevens High School, Edison High School, and Edison Academy Magnet School. Their 2025–26 results show clear strengths in some subjects: the schools’ grade 9 ELA average was 80%, compared with 51% statewide. But the two reported grade 9 Geometry results were 16% and 43%, both below the state’s 50%. The central finding is that results vary sharply by school and subject, so a citywide average masks very different profiles.

Edison Academy Magnet School has the highest reported results on several measures: 100% proficiency in grade 9 ELA, 93% in Algebra II, and a 100% graduation rate. Some of the Academy’s other test results are suppressed, so its reported lead cannot be extended to every subject. Among the two larger schools, John P. Stevens High School led Edison High School on all their reported shared NJSLA tests, including grade 10 Algebra I, 59% versus 17%, a 42-point gap. Edison High had some strengths relative to the state, however: its grade 9 ELA, Algebra II End of Course, and grade 11 science results were 5, 3, and 6 points above state rates, respectively.

Recent changes are mixed: science proficiency rose from 2024–25 to 2025–26 at both larger schools—by 2 points at John P. Stevens High School and 3 points at Edison High School—while Algebra II End of Course fell by 37 and 30 points, respectively. SchoolDigger’s statewide percentile rose from 36 to 45 for Edison High and from 91 to 98 for the Academy, but fell from 90 to 78 for John P. Stevens; these are rankings, not test scores. In SY 2024–25, the free/reduced lunch eligible shares were 49% at Edison High, 16% at John P. Stevens, and 2% at the Academy. Student–teacher ratios were 14.9, 16.0, and 13.8, respectively, offering context but not explaining the differences in results.
