Summary:
Mount Laurel, New Jersey, has nine schools: six elementary schools serving prekindergarten through grade 4, one school for grades 5–6, one middle school for grades 7–8, and an alternative high school serving grades 6–12. In 2025–2026, the elementary schools’ average across grades 3 and 4 was 49% in both ELA and math, compared with a matched-grade state average of 48%. The key finding is that this modest overall edge hides much larger differences between schools and grades.
Countryside Elementary School led the elementary group in third grade, with 59% in both ELA and math—11 and 9 points above state rates. Springville Elementary School led in fourth grade, with 61% in ELA and 63% in math, 15 and 16 points above the state. At the other end, Fleetwood Elementary School had the lowest results in three of four comparisons: 41% in third-grade ELA, 38% in third-grade math, and 40% in fourth-grade ELA, each below the state. T. E. Harrington Middle School had a mixed profile: Algebra I End of Course was 89% versus 40% statewide, while eighth-grade Geometry was 81% versus 86%. Burlington County Alternative High School reported 15% in ninth-grade ELA and 0% in ninth-grade Algebra I; some of its other test results are state-suppressed, so these figures are not a complete picture.
Elementary results improved overall between the two reported years: the average across 24 matched school-grade-subject results rose about 3 points, while the state average fell about 1 point. But fourth-grade ELA and math averages declined about 3 and 4 points, respectively, while third-grade ELA rose about 13 points. Context measures also vary: the **free/reduced lunch eligible** measure for 2024–2025 ranged from 15% at Parkway Elementary School to 29% at Fleetwood; these figures describe school populations and do not explain test results. SchoolDigger’s statewide percentile ranking rose from 37 to 50 for Larchmont Elementary School and from 53 to 60 for Parkway, while Fleetwood’s fell from 46 to 37.
