Summary:
Riverdale School District in Wisconsin serves roughly 631 students across four schools that together cover prekindergarten through 12th grade. Riverdale Elementary handles grades PK–6 with 337 students, Riverdale Junior High serves grades 7–8 with 88 students, Riverdale High covers grades 9–12 with 192 students, and Riverdale Academy, a much smaller setting, serves grades 6–12 with just 14 students. The district as a whole ranks 214th of 432 Wisconsin districts — the 50th percentile — with 3 stars.
Riverdale High is the standout, ranking at the 66th percentile (182nd of 533 schools), up from the 27th percentile the prior year. It graduates 100% of students and reports a 0.0% dropout rate, both better than the district's 93.4% and the state's 92.0%. Its ACT results beat the state in ELA (63.83% vs. 48.47%), math (51.06% vs. 42.93%), and science (53.19% vs. 43.20%). Riverdale Elementary is strongest in math, where every tested grade was above the state in 2025–2026, including 5th grade at 64.71% vs. 51.81%. Riverdale Junior High has the district's best attendance, at 15.0% chronic absenteeism, and science scores consistently above state.
The biggest shared concern is attendance. The district's 21.3% chronic absenteeism rate exceeds the state's 17.3%, and while Elementary and Junior High are below the state rate, Riverdale High sits at 28.2% and Riverdale Academy at 80.0%. The Academy also has a 57.1% graduation rate and the district's highest free/reduced lunch rate at 71.43%, and no test-score data is provided for it. Spending and staffing vary: High spends the most per student ($19,080), Junior High the least ($15,954) and carries the highest student-teacher ratio (16.3), while Elementary has the lowest (12.1).
