ZIP code 53588 in Spring Green, Wisconsin is home to three public schools — River Valley Elementary (PK–2), River Valley Intermediate School (3–6), and River Valley Junior High / High School (7–12) — all in the River Valley School District, which serves 946 students and ranks 154 of 432 Wisconsin districts (64th percentile, 3 stars).

Academic results are strongest in the middle and upper grades. River Valley Intermediate School has 16 of 20 reported tests above state, led by math (8th grade math 85.07 vs 53.06 state; 6th grade math 71.43 vs 53.6), and it posts the second-lowest chronic absenteeism at 13.0%, below both the district (17.1%) and the state (17.3%). River Valley Junior High / High School has climbed steadily in rank, from the 44th percentile in 2023–24 to the 57th and then the 79th percentile (4 stars) in 2025–26, with a 97.9% graduation rate and a 0.0% dropout rate, plus above-state results in 7th and 8th grade math, 10th grade social studies, and ACT ELA and science.

The clearest concerns sit at opposite ends. River Valley Elementary has the lowest chronic absenteeism (6.8%), the highest per-student spending ($19,959) and the smallest classes (10.5 students per teacher), yet all six of its reported tests are below state and its latest rank is 736 of 1044 — 30th percentile, 1 star. Meanwhile, the junior/senior high's chronic absenteeism of 28.5% is far above the district's 17.1% and the state's 17.3%. Parents should note that River Valley Elementary currently serves PK–2, so its reported 3rd and 4th grade test results may reflect an earlier grade configuration at the school.
