Summary:
ZIP code 53573 covers the Muscoda, Wisconsin area, and this data set contains just one elementary school there: Riverdale Elementary, a PK–6 school with 337 students in the Riverdale School District. Because it is the only elementary school in the ZIP code, it is the only local option in these data, and everything below describes that single school rather than a comparison among schools. One useful note for parents: the school's reported test scores are identical to the district's, so the state average is the more meaningful benchmark.
Math is clearly the school's academic strength. In 2025–2026, Riverdale Elementary scored above the Wisconsin average in all four tested math grades, with the largest gaps in 5th grade math (+12.90 points) and 6th grade math (+7.01 points). English language arts is more uneven. Third grade ELA was a weak spot at 39.02% proficient versus 52.08% statewide, a gap of 13.06 points, while 6th grade ELA was a bright spot at 66.67% versus 54.95% statewide. Fourth grade science improved sharply, from 45.45% proficient in 2024–2025 to 62.86% in 2025–2026, moving from below to above the state average. Fourth grade social studies moved the other way, slipping from 67.27% to 62.86%. Across grade-level averages, the school was about 6 points above the state in math but roughly even in ELA in 2025–2026.
Beyond test scores, attendance is a relative bright spot: chronic absenteeism was 17.0% in 2024–2025, essentially matching the state's 17.3% and better than the district's 21.3%. About 56.38% of students qualify for free or reduced lunch, and per-student spending was $16,231, with a 12.1:1 student-teacher ratio. The school holds a 3-star rating, though its state rank percentile has drifted from 61st to 58th to 54th over three years.
