Summary
Sparta Montessori School is a PK–6 public elementary school in Sparta, in western Wisconsin, serving 161 students as part of the Sparta Area School District. Its 2025–26 rank is 718th of 1,039 Wisconsin elementary schools (31st percentile, 2 stars), up from 760th of 1,044 (27th percentile, 1 star) in 2024–25 but still below its earlier highs around the 51st–53rd percentile with 3 stars in 2015–16 to 2018–19. The district is ranked 360th of 432 Wisconsin districts.
Academically, the school’s biggest challenge is math. In 2025–26, math proficiency averaged about 26.7%, far below the district’s roughly 44.0% and the state’s roughly 53.3%; grades 4–6 were especially weak at 25%, 15%, and 16.67%. ELA averaged about 50.2%, slightly above the district’s 48.3% but below the state’s 53.6%. Science and social studies are bright spots: 4th-grade science was 58.33% and social studies 68%, both above district and state. Compared with nearby schools, Tomah Area Montessori School ranks much higher at 197th of 1,039 (81st percentile, 4 stars) and has stronger results despite lower per-student spending ($12,756 vs. $15,723) and a higher student–teacher ratio (20.9 vs. 17.6). Herrman Elementary, in the same district, ranks 626th (40th percentile) and has stronger math in some grades despite much higher poverty.
Attendance is a strength: chronic absenteeism was 8.9% in 2024–25, compared with 17.3% statewide and much lower than nearby Southside Early Learning Center (17.2%), Miller Elementary (24.2%), and Lemonweir Elementary (28.6%). The free/reduced-lunch rate is 29.81%, lower than Herrman (52.76%) and Southside (52.99%), though the school’s student–teacher ratio of 17.6 is high among nearby schools. Subgroup results are uneven: special education students ranked 26th of 802 schools statewide (97th percentile, 5 stars) in 2024–25, an exceptional result, while low-income students ranked 699th of 848 (18th percentile, 1 star) in 2025–26 and female students have been consistently around the 23rd–25th percentile. For parents, the clear priority is math support, especially grades 4–6, while science, social studies, and attendance remain relative strengths.
