Summary
James B Congdon is a K–5 elementary school at 50 Hemlock Street in New Bedford, Massachusetts, serving 299 students as part of the New Bedford district, which ranks 327th of 351 Massachusetts districts in this data (7th percentile, 0 stars).
Against that district backdrop, James B Congdon performs notably better. In 2025–2026 it ranked 418th of 899 Massachusetts elementary schools (54th percentile, 3 stars). Its all-grades proficiency rates were 37.23% in ELA (vs. district 19.81% and state 40.03%), 52.24% in math (vs. district 19.26% and state 41.11%), and 57.14% in science (vs. district 16.05% and state 40.98%). So it is far above its district in all three subjects — above the state in math and science, slightly below in ELA. It is the highest-ranked nearby same-district school in this comparison, ahead of Elizabeth Carter Brooks (489th, 46th percentile) and well ahead of schools such as Alfred J Gomes (878th, 2nd percentile) and Irwin M. Jacobs Elementary School (892nd, 1st percentile). Nearby Dartmouth schools differ: Joseph Demello ranks higher overall (252nd, 72nd percentile, 4 stars) with stronger ELA and math, while Congdon has higher science and a lower student-teacher ratio (10.6).
Results vary by grade and by student group. Fifth grade is the strongest band, with 85.71% proficient in math versus a district figure of 22% and state figure of 39.5%; fourth grade is the weakest, below state in both ELA and math. ELA has improved over three years, from 26.54% to 32.39% to 37.23%, and the school's rank has climbed from 605th in 2022–2023 to 550th, 486th, and 418th, though it remains below its 2018–2019 peak. Subgroup results are often stronger than overall results: special education students rank in the 96th percentile and African American students in the 95th percentile in 2025–2026, with low-income students in the 79th–86th percentile over three years. English language learner results fell to the 21st percentile in 2025–2026 from 88th in 2023–2024. Because science is tested only in fifth grade and subgroup sizes can be small, these figures should be read with caution; free/reduced-lunch data was unavailable.
