Summary:
Deerfield has one elementary school, Deerfield Elementary, serving grades PK–6 with 301 students, in the Deerfield district — ranked 209 of 351 districts (40th percentile, 2 stars) while the school itself has held 3 stars for three straight years, ranking 443 of 899 schools at the 51st percentile in 2025–2026, down from the 58th percentile the prior year.
On 2025–2026 MCAS, results are mixed rather than uniformly strong or weak. Science is the standout at 51.43% proficient versus 40.98% statewide (+10.45 points). Fourth-grade math (51.28% vs 43.20%) and third-grade ELA (48.65% vs 42.79%) also beat the state. Weaker areas include fourth-grade ELA at 28.21% versus 37.43% (−9.22 points), fifth-grade math at 34.29% versus 39.50%, and third-grade math at 37.84% versus 42.19%. All-grade ELA is essentially at state (39.76% vs 40.03%), and all-grade math is slightly above (41.57% vs 41.11%). This grade-level spread — for instance, 4th-grade ELA and 4th-grade math differ by more than 23 points — points to subject- and grade-specific patterns rather than one school-wide trend.
Year over year, math fell from 49.40% to 41.57% and ELA from 46.43% to 39.76%, while science jumped from 33.90% to 51.43%; since elementary science is tested in grade 5, that swing likely reflects a different cohort and small numbers, so it should be read with caution. Structural context: the student-to-teacher ratio is a low 8.8, and per-student spending was $21,413 in 2020–2021. The 2024–2025 free/reduced-lunch percentage was not reported, so it should not be read as 0%. District results match the school's exactly in every reported row, indicating this is the only tested school feeding those district figures.
