Summary:
ZIP code 08540 has one listed middle school, Princeton Middle School, serving grades 6–8 with 794 students in the Princeton Public School District; there is no second school for a meaningful local comparison. The clearest concern is the sharp drop in reported math proficiency in grade 8: 7% at Princeton, compared with 23% statewide, a 16-point shortfall.
Princeton is both the top and bottom school in this one-school listing, so its results are best judged against New Jersey’s. Its ELA results were strong in all three grades in 2025–2026: the school averaged 83% proficient, about 30 points above the state average. Math was also far above the state in grades 6 and 7, by 41 and 31 points, respectively. Grade 8 math was the major exception. In 8th-grade science, Princeton reached 56% proficient versus 19% statewide, a 37-point advantage. Separate course tests were high as well: Princeton had 100% proficient in 7th-grade Algebra I and 8th-grade Algebra II, and 96% in Geometry end-of-course.
Recent results show strong performance overall but some grade-specific declines. Princeton’s average ELA proficiency fell from 85% in 2024–2025 to 83% in 2025–2026, while the state average fell from 57% to 53%; Princeton’s advantage grew from 29 to 30 points. Grade 7 math fell by 5 points, while grade 6 stayed at 81%; the data do not include a prior-year grade 8 math score. SchoolDigger ranked Princeton 55th of 743 schools, in the 93rd percentile, in 2025–2026, up from 73rd of 752 and the 90th percentile the year before. As context, its 2024–2025 student–teacher ratio was 11.8, and 14% of students were free/reduced lunch eligible that school year.
