Princeton Public School District

Princeton Public School District includes six schools serving preschool through grade 12: four elementary schools, one middle school and one high school, with 3,668 students altogether. Overall, elementary, middle-school ELA and science, and several high-school results are above state comparisons, but that strength is not consistent across subjects and grades. The most important exception is math: grade-8 math at Princeton Middle School and Algebra I at Princeton High School are well below state results.

Riverside School stands out among elementary schools, averaging 78% in ELA and 79% in math across grades 3–5, compared with four-school averages of 73% and 74%. The four-school averages are also above state grade averages: by 25 points in ELA, 27 in math and 35 in grade-5 science. Johnson Park School leads grade-3 ELA at 79%, while Riverside leads grade-4 and grade-5 ELA at 81% and 83%; Riverside and Littlebrook School tie in grade-5 science at 67%. At the lower end of the school averages, Littlebrook has the lowest ELA result at 68%, and Community Park School the lowest math result at 70%. At the upper grades, Princeton Middle’s grade-8 math is 7%, versus 23% statewide, and Princeton High’s Algebra I result is 15%, versus 40% statewide.

Recent trends are mixed: elementary ELA averages rose 2 points from 2024–2025 to 2025–2026, while math averages fell 3 points and the school-to-state math advantage narrowed by 3 points. At Princeton High, grade-9 ELA rose 5 points, but grade-11 science fell 25 points, moving from 19 points above the state to 4 points below. SchoolDigger ranks Riverside in the 94th percentile among state elementary schools and Princeton Middle in the 93rd percentile among middle schools; those are rankings, not test scores. For context, all six schools report free/reduced lunch eligible for school year 2024–2025; elementary-school shares range from 11% at Littlebrook to 21% at Johnson Park. Riverside has the lowest elementary student-teacher ratio, 7.8, but these context measures alone do not explain school results. Year-to-year figures describe grade-level results, not the progress of the same students.
