The clearest finding for families is that results were above the state in every reported regular-grade ELA and math comparison, but performance varied notably by grade, especially in math.

There is no meaningful top-to-bottom comparison among schools because Cranbury is the only school listed. Within the school, eighth-grade Geometry and seventh-grade Algebra I were standout course results: both had 100% proficiency, compared with 86% and 93% statewide. Among regular grade-level tests, third-grade math was highest at 85%—36 points above the state—while eighth-grade math was lowest at 38%, still 15 points above the state. Math results spanned 38% to 85% across grades, a wider spread than ELA’s 67% to 81%.
