Summary
Rock River Intermediate is a grade 2–6 school in the Waupun School District in Waupun, Wisconsin, enrolling 585 students — more than double most nearby elementary schools. It ranks 600th of 1,039 Wisconsin schools in 2025–2026 (42nd percentile, 2 stars), well above its own district's 26th percentile but still in the lower-middle tier statewide. The school's rank slipped from the 59th percentile in 2015–2016 to the 48th by 2018–2019 and has hovered between the 40th and 46th percentiles since 2020–2021. Chronic absenteeism is 12.4%, better than the district's 17.1% and the state's 17.3%, and 39.66% of students qualify for free or reduced-price lunch. Per-student spending is $14,492, up from $11,956 in 2021–2022, with a student-teacher ratio of 14.1.
Academically, the school is mixed. Math is at or above state averages in most grades (grades 3–6 average 54.6% vs. the state's 53.3%), and 4th grade social studies is a clear strength at 70.37% vs. 65.51%. Science is near the state average. English language arts is the main weakness, below the state at every grade and averaging about 8 points lower. Third grade ELA is the biggest gap: 36.94% vs. the state's 52.08%. By 6th grade, ELA is closer (50.00% vs. 54.95%), suggesting early literacy is the highest-leverage focus.
Compared with neighbors, Rock River sits mid-pack. It outranks its own district and the same-district School for Agricultural and Environmental Studies, but trails Oakfield Elementary (97th percentile), Prairie View Elementary (91st), Laconia Elementary School (85th), Washington Elementary (84th), Lincoln Elementary (57th), Markesan Intermediate (51st), and Mayville Elementary (51st). Notably, Prairie View serves a similar share of low-income students yet scores far higher with much lower absenteeism, and Washington has more low-income students and a higher student-teacher ratio yet still outperforms — so demographics and spending alone do not explain results. Effectiveness also varies by group: female students rank near the middle, male students lower, and special education results swing widely year to year.
