Estimated ESA money
An estimate: the state doesn’t publish how many students at each school have an education savings account, or how much is paid for them. How ESAs work
About $548,000 in 2025–26, if this school’s students had ESAs as often as private-school students statewide.
| School year | Students | × Share with an ESA (statewide) | × Per student | = Estimate |
|---|---|---|---|---|
| 2025–26 | 70 | 98.0% (41,044 ÷ 41,892) | $7,988 | $548,000 |
The share is all ESA accounts at the October count divided by all private-school students that year.3 It’s close for 2025–26 on, when nearly every private-school student qualified. For 2023–24 and 2024–25 it’s rough: only some families qualified (kindergartners, students new to private school, and lower-income families), so the share differed a lot from school to school.
Where its students live
The public school district each student lives in. The public district gets no state aid for them, and the state’s ESA money follows them here.
Finances (Form 990)
The nonprofit that runs the school files an annual return with the IRS.
Willowwind School (EIN 23-7411810). These cover the whole organization, which may run more than one building.4

What isn’t public
Iowa pays for most private-school students now, but it publishes much less about private schools than about public ones. None of these exist for any Iowa private school:
- Exact ESA money or students by school. The ESA law (Iowa Code 257.11B) and its rules (281 IAC chapter 20) require no report by school; the Department of Education publishes ESA counts only by the public district where students live. The money sits in a state fund and is paid out by a contractor, so it doesn’t show in the state checkbook by school.5 That’s why the dollars here are estimates.
- Graduation rates. The state’s graduation rates count public-school students only; its cohort definition leaves out home-schooled and nonpublic students.6
- Attendance and chronic absence. Reported for public districts only.
- Official ratings. The Iowa School Performance Profiles and federal school designations cover public schools only. Private schools get no state rating, and Funnel doesn’t make one: test results below are shown grade by grade, never combined into a score.
- Tuition. No state source lists it. The Department of Revenue’s 2022 study of School Tuition Organizations found an average tuition of $4,596 in 2021–22 across the schools in its data, ranging from $150 to $11,044.7
- STO scholarships by school. School Tuition Organizations must report each school’s scholarship students and dollars to the Department of Revenue (Iowa Code 422.11S(9)(e)), but the department doesn’t publish them; only each STO’s yearly tax credits are public (on Tax credits).
