The middle 50% of University of Iowa students who enrolled and submitted an ACT scored between 21 and 28 on the composite, and the university reports a midpoint of 26. That 7-point spread is wide, which means there is no single Iowa number to chase. The overall admission rate is 84%, an institution-wide figure covering all applicants, and the undergraduate student body is 22,264. Below: what each number describes, what it cannot tell you, and how to read your own practice score against it.
These figures come from the US Department of Education College Scorecard, which draws on IPEDS, for the most recent reported cohort. Everything on this page is built from this table and nothing else.
| Figure | Value | What it describes |
|---|---|---|
| ACT composite, 25th percentile | 21 | 25% of enrolled students who submitted a score were at 21 or below, so about 75% were above it |
| Reported midpoint | 26 | The midpoint of the reported range. Not a verified median |
| ACT composite, 75th percentile | 28 | 75% were at 28 or below, so roughly the top quarter was above it |
| Width of the middle 50% | 7 points | The span from 21 to 28, where half of the reported composites sat |
| Overall admission rate | 84% | Institution-wide, across all applicants. Not a personal probability |
| Undergraduate enrollment | 22,264 | Size of the undergraduate student body |
Two cautions before you read anything into these. First, no percentile here is a cutoff, a minimum, or a requirement. Each one is a description of scores that appeared in an enrolled class. Second, the group being described is narrower than it looks: students who enrolled and submitted an ACT. Applicants who were not admitted are not in it, and neither are admitted students who chose a different school. Keep both of those in mind for the rest of the page.
The gap between 21 and 28 is 7 points. Half of the reported composites sat inside that span. The other half splits roughly in two: about a quarter at or below 21, about a quarter above 28.
Width matters more than most students realize. Imagine a school reporting a band of 25 to 28 instead. A 24 would fall outside it, below the bottom quarter line. At Iowa the reported floor of the middle 50% is 21, so a 24 sits inside the band with room on both sides. A 22 does too. So does a 27. Three students with genuinely different scores all land inside the middle half of the same reported class.
Practical consequences:
A band this wide also means moderate gains are meaningful. Going from 22 to 25 does not flip you into a new category, but it moves you a real distance across the middle half. The mechanics of doing that are in how to improve an ACT score.
Iowa's overall admission rate is 84%. Read literally, that means the institution admitted roughly 84 of every 100 applicants across the whole university in the reported year. Read as a personal probability, it means nothing, and treating it that way is the most common mistake made with numbers like this.
Two reasons it cannot be personalized:
What the two numbers do together is set context, not odds. A 7-point reported band alongside a high institution-wide admission rate describes a large university, 22,264 undergraduates, that enrolled students across a broad span of composites. That is a different picture from a school with a narrow band and a low rate, where reported scores are compressed near the top. Context helps you plan. Prediction is not on offer here, and any site that multiplies these two numbers into a percentage chance of admission is inventing it. For how to compare bands across your whole list, see college ACT scores.
Average the two percentiles and you get 24.5. The reported midpoint is 26. Those are different numbers, and the gap is worth understanding before you lean on either one.
The midpoint is reported separately: it is the midpoint of the range the institution reported, not a verified median and not a mean of student scores. It sits 5 points above the 25th percentile and only 2 points below the 75th. So the three figures are not evenly spaced, and the middle half of the band is not symmetric around 26.
How to handle that:
If percentiles still feel slippery, our general explainer on how ACT scores work walks through what a percentile is, how a composite is built, and why a reported band is a description rather than a target.
Take a full-length timed form, then place the result. The table below is positional only. It tells you where a composite sits relative to scores reported by enrolled students who submitted one. It does not tell you whether you will be admitted, and no table can do that.
| Practice composite | Position in the reported band | Reasonable next move |
|---|---|---|
| 20 or below | Below the reported 25th percentile of 21 | Accuracy before speed. Pick your weakest of English, Math, and Reading and work the questions you already almost get right. |
| 21 to 25 | Inside the band, in its lower half | Timing and triage. Take a second timed form and compare section by section, not composite to composite. |
| 26 to 27 | At or above the reported midpoint of 26 | Chase consistency. Two forms within a point of each other tell you more than one good day. |
| 28 or above | At or above the reported 75th percentile of 28 | Protect what you have. Short frequent sessions, and review every miss for the reason, not just the right answer. |
Every step there has a free tool behind it: practice tests, with 2 of the 6 full-length timed forms free, the ACT score calculator to turn raw counts into a composite, the study plan builder to fit the weeks you actually have, and the score forecast. Not sure when to sit for it? Start with ACT test dates, then how to study for the ACT.
Whatever range you set, drill on the current format. The Enhanced ACT that took effect in 2025 is shorter than the test most older materials were written for.
Note what that last set of facts implies for a 7-point band like Iowa's: the composite rests on three scored sections, so a single weak section drags the whole number down by about a third of its deficit. Finding which section is costing you the most is usually worth more than general review.
What Prep36 gives you at no cost: the entire bank of 1,026 original practice questions, each with an instant explanation on every answer, 2 of the 6 full-length timed forms, the score calculator, the study plan builder, the score forecast, and the Enhanced ACT Cram Kit if your test date is close.

The honest boundary is more useful to you than a confident guess, so here is what we do not have for the University of Iowa.
What you can take away: half of the reported composites sat between 21 and 28, the reported midpoint was 26, and the institution-wide admission rate was 84% among 22,264 undergraduates. Use those to aim your practice, then get the policy details from the university itself. Prep36 is not affiliated with ACT, Inc.
A composite is not a number you score directly. On the Enhanced ACT it is the average of English, Math and Reading, so reaching one means hitting that scaled score across three sections. Science is optional and reported separately, so it is left out here.
Below is what each scaled score actually costs in correct answers, and how many questions you can afford to miss to still land on it.
| Section | For a 21 | For a 26 | For a 28 |
|---|---|---|---|
| English 50 questions | 32 of 50 miss up to 18 | 40 of 50 miss up to 10 | 42 of 50 miss up to 8 |
| Math 45 questions | 24 of 45 miss up to 21 | 30 of 45 miss up to 15 | 33 of 45 miss up to 12 |
| Reading 36 questions | 21 of 36 miss up to 15 | 28 of 36 miss up to 8 | 29 of 36 miss up to 7 |
Read this correctly. These are not section targets for this school. The College Scorecard reports composite percentiles only, with no section-level data, so nobody can tell you what English or Math score this school expects. What the table shows is the raw cost of a 21 and a 28 in each section, whoever you are aiming at. Build your own section goals from your own practice results.
