Summary
Jefferson Elementary is a PK–5 school serving 393 students at 7229 W Becher St in West Allis, Wisconsin, part of the West Allis-West Milwaukee School District. In 2025–26 it ranked 912th of 1,039 Wisconsin elementary schools (12th percentile, 1 star), and its district ranks 400th of 432 statewide. Its rank history shows a long-term decline: 42nd percentile with 2 stars in 2015–16, then mostly 1 star since, with recent percentiles of 18, 19, 17, 16, and 12.
Achievement is the clearest concern. In 2025–26, Jefferson's ELA and math proficiency fell below both district and state at every grade level — 22.73 in grade 3 ELA versus 35.58 district and 52.08 state, and 24.62 in grade 3 math. Science is the bright spot at 36.36, above the district's 34.43 and above several nearby same-district schools, though still below the state's 53.46. Jefferson also trails most same-district neighbors: Mitchell Elementary, about two miles away, sits at the 51st percentile with 3 stars, 3.9% chronic absenteeism, and far higher test scores. Jefferson's chronic absenteeism improved to 16.4%, better than district (19.5%) and state (17.3%) rates but higher than Pershing Elementary, Irving Elementary, Franklin Elementary, Wilson Elementary, and Mitchell.
Resources don't obviously explain the gap: Jefferson spends $15,907 per student with a 12.5 student-teacher ratio, lower than most nearby schools, including Mitchell (14.7). Effectiveness rankings by subgroup vary widely, with some groups far above the school's overall percentile while others rank in the low teens. Grade-level scores also swing sharply year to year — grade 5 ELA fell from 43.28 to 27.27 — suggesting cohort effects or instructional inconsistency.
