Summary
South Row is a K–4 elementary school serving 464 students in Chelmsford, MA, a suburban community northwest of Boston, and is part of the Chelmsford district. South Row ranked 131st of 899 Massachusetts elementary schools in 2025–2026 (85th percentile, 4 stars), placing it in the top 15% statewide, while the Chelmsford district ranks 73rd of 351 districts (79th percentile, 4 stars). The school has earned 4 stars every year shown, has never fallen below the 74th percentile, and has climbed steadily from 204th of 916 in 2023–2024 to 147th of 906 in 2024–2025 and then 131st of 899 in 2025–2026.
On the 2025–2026 MCAS Next Generation tests, 59.3% of South Row students were proficient in English Language Arts and 67.05% in Mathematics, well above the Chelmsford district (53.49% ELA, 55% Math) and the state (40.03% ELA, 41.11% Math). Math is the clear standout: South Row's 67.05% is the highest among nearby K–4 schools, ahead of Byam School (55.61%) and Center Elementary School (56.82%). ELA is essentially tied with Byam (59.11%) and clearly ahead of Center (51.43%). Grade-level results split noticeably: 3rd grade was strong (67.9% ELA, 75.31% Math — higher in math than Carlisle School's 67.19%), while 4th grade was softer (51.65% ELA, 59.78% Math), with 4th-grade ELA below Byam and Center though still above the state.
Relative effectiveness — how well the school serves particular groups compared with other schools statewide — is strongest for low socio-economic status students (92nd percentile, 5 stars, in 2024–2025), special education students (81st percentile), and male students (87th percentile); female students improved to the 82nd percentile. Relative ranks are lower for Asian students (54th percentile) and White students (73rd percentile), both still at or above the middle of the statewide range. South Row's 2024–2025 student-teacher ratio was 13.3, a bit higher than Center (12.8) and Byam (12.9), and its 2020–2021 per-student spending of $16,510 was the second-lowest in this comparison set. Free/reduced lunch data were not reported, and spending figures predate 2021, so resource comparisons should be treated as directional rather than definitive.
