Summary:
ZIP code 08534 has eight listed schools—two elementary, one middle and five high schools—covering traditional district schools and county technical programs; 2025–2026 test results are available for six. Both elementary schools scored above state rates in every reported grade-level ELA and math comparison, and Timberlane Middle School was well above state rates in ELA in grades 6–8. The most important finding is that high-school results vary sharply by program, so an area-wide average would hide meaningful differences.
Toll Gate Grammar School leads many elementary comparisons: it reached 93% in grade 5 math and 75% in grade 5 science, while Stony Brook Elementary School led grade 4 ELA at 81%. At Timberlane, ELA exceeded state rates by 26 points in grade 6, 30 in grade 7 and 25 in grade 8; grade 8 math was a weaker spot, at 20% versus 23% statewide. Among high schools, Hopewell Valley Central High School and Mercer County Technical School STEM Academy had grade 9 ELA results of 76% and 72%, compared with 28% at Mercer County Technical School Culinary Arts Academy. Central also led grade 9 Algebra I (35%); Culinary Arts was lowest at 4%, against 22% statewide. Central’s grade 11 science result was 63%, versus 52% at STEM and 25% at Culinary Arts. The two other listed high schools, MCVS Assunpink Shared Time Center/Rubino and MCVS Arthur R. Sypek Center, have no supplied test-score results.
