Summary:
Mount Laurel Township School District includes eight schools serving prekindergarten through grade 8: six elementary schools for PK–4, Hartford Upper Elementary School for grades 5–6, and T. E. Harrington Middle School for grades 7–8; together they enroll 4,173 students. The latest elementary results average slightly above state results overall, but that district-wide picture masks the most important finding: elementary scores vary widely, with school-to-school gaps of 18 to 24 points on matched tests.
Springville Elementary School leads the elementary schools on the average of four grade 3 and 4 ELA and math results, at 57%, 9 points above the matching state average. Parkway Elementary School averages 54%, 7 points above state, while Countryside Elementary School averages 51%, 4 points above, and leads grade 3 ELA and math at 59% in each. At the lower end, Fleetwood Elementary School averages 41%, 7 points below state; Hillside Elementary School averages 43%, 4 points below. Harrington’s results vary by subject: grade 8 math is 14 points above state, while grade 8 ELA is 5 points below.
Elementary ELA improved relative to the state between 2024–2025 and 2025–2026: the six-school average rose 5 points, while the state average fell 2 points, shifting the area from 5 points below to 2 above state. Elementary math was essentially unchanged. SchoolDigger’s ranking percentile rose for Larchmont Elementary School from 37 to 50 and for Parkway from 53 to 60, while other schools’ rankings declined. As context, free/reduced lunch eligible figures for 2024–2025 ranged among elementary schools from 15% at Parkway to 29% at Fleetwood; these figures do not explain the differences in results.
