Summary:

Schools in zip code 08691 include four schools serving pre-K through grade 12: Sharon School, Pond Road Middle School, Richard C. Crockett Middle School, and Robbinsville High School. Three are in Robbinsville Public School District, while Crockett is in Hamilton Township Public School District; together they enroll 3,907 students. The clearest school-to-school comparison is between the two middle schools: in 2025–2026, Pond Road outperformed Crockett in all seven matched ELA, math, and grade-8 science results, with gaps of 29.6–40.9 points in ELA and 33.3–49.4 points in math.

Pond Road is the strongest middle-school performer: its grade 6–8 averages were 73% in ELA and 70% in math, respectively 20 and 37 points above state averages. Crockett averaged 38% in ELA and 29% in math—16 and 5 points below the state—and had 10% grade-8 science proficiency versus 19% statewide. The other schools also exceeded their state comparisons: Sharon was 25 points above the state in grades 3–4 ELA and 23 points above in math; Robbinsville High was 22 points above in grade-9 ELA, 28 above in grade-11 NJGPA math, and 31 above in grade-11 science. Comparisons use the same grades and subjects.

Recent results show improvement overall but not in every grade or test: across matched elementary and middle-grade entries, the average school-to-state gap for Sharon, Pond Road, and Crockett rose from 10 points in 2024–2025 to 13 points in 2025–2026. Crockett’s averages improved by 2 points in ELA and 6 in math, though they remained below state averages; Pond Road’s grade-8 ELA rose 14 points while its grade-7 ELA fell 5.
