Summary
Edward F. Parthum is a K–4 elementary school at 255 E Haverhill Street in Lawrence, MA, serving 656 students, which makes it one of the larger elementary schools in its comparison group. It is part of the Lawrence school district, which is ranked 337th of 351 in Massachusetts — and nearly every nearby Lawrence school shares that same low district rank. Parthum's own statewide ranking has stayed near the bottom: in 2025–2026 it ranked 820th of 899 schools — the 9th percentile — with 0 stars, down from 747th of 906 (18th percentile, 1 star) the year before.
On 2025–2026 MCAS Next Generation, Parthum's all-grade proficiency was 18.49% in English Language Arts and 18.63% in Math — slightly above the Lawrence district averages of 17.46% and 17.28%, but far below the state averages of 40.03% and 41.11%. The school outperforms Arlington Elementary, Francis M Leahy Elementary, and Henry K. Oliver Elementary, but trails South Lawrence East Elementary School (22.12% ELA, 29.82% math) and John K Tarbox (19.28% ELA, 31.71% math), and sits roughly 24–30 points below Thomson in North Andover and Community Day Charter Public School. Grade 3 is much stronger than grade 4: grade 3 ELA was 24.39% and math 23.77%, while grade 4 ELA was 13.38% and math 14.18%, with grade 4 math slightly below the district average.
Subgroup effectiveness ranks are uneven. In 2025–2026, the school ranked at the 35th percentile for Hispanic students, 31st for English Language Learner students, 19th for low socioeconomic status students, 13th for female students, 7th for male students, and 6th for special education students — all lower than in 2024–2025, when Hispanic students were at the 66th percentile and English Language Learner students at the 85th. Math had been a relative strength, running about 9–10 points above district in 2023–2024 and 2024–2025, but that edge narrowed to about 1.4 points in 2025–2026. Parthum's student-teacher ratio of 13.3 is higher than most nearby schools, and per-student spending of $15,711 (2020–2021) was below several nearby Lawrence schools; that spending figure is historical context only. Free/reduced-price lunch data were not available, so economic disadvantage could not be analyzed directly.
