Summary:
Muscoda, Wisconsin is home to two high schools—Riverdale High and Riverdale Academy—both part of the Riverdale School District and both at the same address, 235 E Elm St. Riverdale High serves grades 9–12 with 192 students; Riverdale Academy serves grades 6–12 with 14 students, giving the area a combined high-school enrollment of 206. The two schools share a district rated 214 of 432 (50th percentile, 3 stars), yet their profiles are strikingly different.
Riverdale High is the larger school and posts strong outcomes. Its 2024–2025 graduation rate is 100.0%, above the district's 93.4% and the state's 92.0%, with a 0.0% dropout rate. In 2025–2026, ACT proficiency is above district and state in English language arts, mathematics, and science, and the school's rank climbed from 315 of 431 (27th percentile, 1 star) to 182 of 533 (66th percentile, 3 stars). Two areas lag: chronic absenteeism is 28.2%, versus 21.3% district and 17.3% state, and social studies proficiency is 35.42%, below the district's 36.73% and the state's 48.25%.
Riverdale Academy presents a very different picture. Chronic absenteeism is 80.0%—roughly 3.8 times the district rate and 4.6 times the state rate—and its graduation rate is 57.1%. It also serves a higher-poverty population (71.43% free/reduced lunch versus 44.27% at Riverdale High) while spending less per student ($15,471 versus $19,080) with a higher student-teacher ratio (15.5 versus 13.6). With only 14 students, a single student can shift a percentage by about 7.1 points, so these figures should be read as directional. Riverdale Academy also has no test scores or rank history listed here, so its academic proficiency cannot be compared directly.
