In 2025–2026, all-grades proficiency was 70.2% in ELA, 74.08% in math, and 62.36% in science. Compared with the state, that is +30.17 points in ELA, +32.97 points in math, and +21.38 points in science. Compared with the district, the school was +2.82 points in ELA and +2.80 points in math, but -4.83 points in science. Grade-level results show math 7th grade at 77.99%, the highest single result, and ELA rising from 65.81% in 6th grade to 71.06% in 7th and 74.52% in 8th. In 8th grade, ELA (74.52%) slightly edges math (73.11%), while science (62.36%) and civics (63.36%) are lower internally but still above state averages by more than 23 points.
Year over year, proficiency fell in every reported subject from 2024–2025 to 2025–2026: ELA -2.69 points, math -2.06, science -5.70, and 8th grade civics -12.31. The civics drop mirrors a district decline from 75% to 63.02%, so it is not unique to this school. Student-to-teacher ratio is 9.9, and per-student spending is $19,571 for 2020–2021; free/reduced-lunch data is not reported in this extract. Overall, Ephraim Curtis Middle remains a high-performing, top-decile school with standout math and ELA results, though science and civics are relative weak spots and recent declines are worth monitoring.
