Summary
Lakeside School is a grades 6–8 middle school in Pompton Lakes, New Jersey, serving 370 students. Its latest results show a mix of strengths and concerns: English Language Arts (ELA) and some math results are above state averages, but eighth-grade math stands out as a serious weakness. In 2025–2026, 12% of Lakeside eighth-graders were proficient in math, compared with 23% statewide and a 41% average across nearby schools; Lakeside scored below every nearby school.
Lakeside’s strongest comparisons are in ELA and end-of-course Algebra I, though nearby schools often score higher. ELA results were 54% in grade 6, 70% in grade 7 and 62% in grade 8, all above state results of 51%, 56% and 53%. Still, Lakeside was below nearby-school averages in each grade. In math, grades 6 and 7 were above state averages—42% versus 40% and 53% versus 38%—but below nearby averages of 49% and 55%. Eighth-grade science was also low: 12% proficient versus 19% statewide and a 31% nearby-school average. End-of-course Algebra I is a relative strength against the state and district: Lakeside scored 69%, versus 40% statewide and 28% in the Pompton Lakes School District. However, the nearby-school average was 94%.

Across 2022–2023 to 2025–2026, the three-grade math average increased 5 points, but eighth-grade science stayed nearly unchanged at about 13%.
