Summary
Columbus School in Lodi, New Jersey, serves 265 students in prekindergarten through grade 5. Its latest results show a mixed academic picture: math compares favorably with nearby schools, while ELA varies by grade and recent results have dropped from earlier years. The clearest concern is grade 5 science: 17% of students were proficient in 2025–26, compared with 27% in the Lodi School District, 27% statewide and 24% at nearby schools on average.
Math is a relative strength against nearby schools, though not against the district or state overall. Columbus averaged 46% proficiency across grades 3–5, below the district’s 50% and the state’s 47%; still, its grade-level results were 9, 4 and 7 percentage points above nearby-school averages in grades 3, 4 and 5. ELA results show a sharper grade-level contrast: grade 3 proficiency was 36%, below the district’s 44%, the state’s 48% and the nearby-school average of 44%. Grade 5 ELA was stronger at 53%, above the state by 2 points and nearby schools by 3 points.
Results have weakened since 2022–23, particularly in ELA: the grades 3–5 average fell from 66% to 46% by 2025–26, while the math average declined from 52% to 46%. Science rose slightly across those years, from 14% to 17%, but fluctuated considerably in between. SchoolDigger’s statewide percentile fell from 67 in 2024–25 to 44 in 2025–26, and its rating dropped from 3 stars to 2. Attendance is a positive: chronic absenteeism was 10% in 2024–25, down from 17% in 2023–24 and below the state’s 14%. Columbus had a student-teacher ratio of 15.5 in 2024–25, the highest among nearby schools with data, despite having the second-lowest enrollment. Its free/reduced lunch eligible share was 60% that year, below the other Lodi schools but close to the nearby-school average. SchoolDigger’s 2025–26 rankings show stronger statewide standing for English Language Learner Students (73rd percentile) and Low Socio Economic Status Students (68th) than for the school overall; the latter fell 28 points from 2023–24.
