Summary:
Riverdale School District serves two high schools in the Muscoda, Wisconsin area — Riverdale High (grades 9–12, 192 students) and Riverdale Academy (grades 6–12, 14 students) — both listed at 235 E Elm St, with the district ranked 214 of 432 schools at the 50th percentile with 3 stars.
Riverdale High posts the strongest outcomes: a 100.0% graduation rate and 0.0% dropout rate, both above the district (93.4% and 0.0%) and state (92.0% and 1.1%). Its 2025–2026 ACT proficiency is above district and state in English Language Arts (63.83), Mathematics (51.06), and Science (53.19) — a dramatic reversal from 2024–2025, when Mathematics was 21.28 and Science 23.4. Its school rank jumped from 315 of 431 (27th percentile, 1 star) to 182 of 533 (66th percentile, 3 stars). The weak spots: chronic absenteeism of 28.2% (district 21.3%, state 17.3%), and Social Studies Forward proficiency falling from 72.34 to 35.42, below both district (36.73) and state (48.25).
Riverdale Academy shows a very different profile: a 57.1% graduation rate, 80.0% chronic absenteeism, and 71.43% free/reduced lunch eligibility versus 44.27% at Riverdale High. It spends $15,471 per student compared with $19,080, and has a higher student-teacher ratio (15.5 vs 13.6). No test-score data is listed for the school. With only 14 students, its rates can shift sharply from one student to the next, so treat them as signals of challenge rather than stable estimates.
