Summary:
Seven schools in ZIP code 08648, all part of Lawrence Township Public School District, serve prekindergarten through grade 12: four elementary schools through grade 3, an intermediate school for grades 4–6, a middle school for grades 7–8, and a high school for grades 9–12. The latest results show stronger performance in some grade groups than others, rather than one consistent pattern across the area. Most notably, the four elementary schools’ average third-grade results moved from below the state average in 2024–2025 to above it in both ELA and math in 2025–2026.
Lawrenceville Elementary School leads in third-grade ELA at 66%, while Slackwood Elementary School leads in math at 63%, 3 points ahead of Lawrenceville. At the other end, Ben Franklin Elementary has the lowest third-grade scores among the four schools, at 52% in ELA and 51% in math; both are still above state results. Lawrence Middle School has strong seventh-grade results and 99% proficiency in eighth-grade Algebra I, but eighth-grade math is 18%, below the state’s 23%. Lawrence High School is also mixed: ninth-grade ELA is 61%, above the state, while ninth-grade Algebra I is 15%, below it.
Recent elementary gains are especially notable at Slackwood, where third-grade ELA rose 24 percentage points and math rose 21 points in one year; Lawrenceville gained 17 points in ELA and 16 in math. SchoolDigger’s ranking percentile rose from 31 to 67 for Slackwood and from 48 to 73 for Lawrenceville. Results did not rise everywhere: Ben Franklin’s scores changed little, while Lawrence High’s NJGPA ELA and math results declined year over year. The schools’ reported free/reduced lunch eligible shares for sy 2024–2025 range from 19% at Lawrenceville to 60% at Slackwood; these figures provide context, not an explanation for results. Elementary student-teacher ratios range from 9.5 at Ben Franklin to 10.5 at Slackwood, with no simple match to scores.
