Summary:
ZIP code 53588 contains exactly one public high school: River Valley Junior High / High School, a combined junior and senior high in Spring Green, Wisconsin, serving grades 7–12 with 364 students. It is the only high school in the River Valley School District at this level, so there are no other local schools to compare it against; state averages are the most useful benchmark. On every listed test, the district's results match the school's results, which is consistent with it being the only school in the district at these grades.
The school's story is one of clear improvement. Its state ranking rose from 240 of 431 schools (44th percentile, 2 stars) in 2023–24, to 187 of 431 (57th percentile, 3 stars) in 2024–25, and to 111 of 533 (79th percentile, 4 stars) in 2025–26. High school outcomes are strong: the graduation rate is 97.9% versus 92.0% statewide, and the dropout rate is 0.0% versus 1.1% statewide. Test results show above-state performance in 7th-grade math (+13.25 points), 8th-grade math (+18.12), 10th-grade social studies (+18.42), 8th-grade science (+7.11), ACT ELA (+12.96), and ACT Science (+6.80). ACT results also improved year over year in ELA, math, and science.
Two areas need attention. Chronic absenteeism is 28.5%, well above both the district (17.1%) and the state (17.3%) — roughly 65% higher than the state rate — despite the strong graduation and test results. Also, junior high English language arts lags the state in 7th grade (-6.68 points) and especially 8th grade (-17.20 points), and 8th-grade social studies is below state (-6.94). ACT math sits essentially at the state average (42.86% vs 42.93%). For context, 30.77% of students are economically disadvantaged by the free/reduced-lunch measure, per-student spending is $18,035, and the student-teacher ratio is 12.4.
