Indiana University-Bloomington ACT Scores: A 27 to 33 Middle 50%

Enrolled students at Indiana University-Bloomington who submitted an ACT scored between 27 and 33 across the middle 50 percent, with a reported midpoint of 29. The overall admission rate is 78 percent, and undergraduate enrollment is 37,806 in Bloomington, Indiana. Those two facts sit together in a way worth pausing on: a 6-point score band and a high institution-wide rate mean this range describes who enrolled, not a bar anyone has to clear. Here is what each figure says, what it cannot say, and how to read your own composite against it.

The three composite figures, one at a time

These numbers come from the U.S. Department of Education College Scorecard, sourced from IPEDS, for the most recent reported cohort. Every one of them describes enrolled students who submitted an ACT score. They do not describe applicants, and they do not describe students who were admitted and went somewhere else.

A 6-point spread is genuinely wide. Half of the reported scores land inside it, and the remaining half splits between below 27 and above 33. None of these figures is a cutoff, a minimum, or a requirement. A percentile is a position inside a distribution that has already happened. Nobody set 27 as a floor. It is just where the bottom quarter of reported scores happened to end. If percentile language is new to you, our guide to ACT scores walks through it in plain terms.

Why 29 sits low inside a 27 to 33 band

Do the arithmetic and something stands out. The exact center between 27 and 33 is 30, but the reported midpoint is 29. The two halves of the band are not the same size.

Read that carefully, and with a hedge. Because the reported midpoint is a reported figure rather than a verified median, treat this asymmetry as a hint about the shape of the distribution, not as a measurement. What it suggests is that the lower half of the band is compressed into a narrow 2-point window while the upper half stretches across 4 points.

The practical consequence for a student: the difference between a 27 and a 29 is small in points but covers a lot of ground inside this range, while the climb from 29 to 33 is a longer stretch of the same band. If you are at 27 or 28, you are already inside the middle 50 percent. If you are aiming for the top of it, understand that you are targeting the wider half. Our free ACT score calculator converts raw section performance into composite estimates so you can see what a 2-point move requires.

A 78 percent admission rate across 37,806 undergraduates

The 78 percent admission rate is institution-wide, covering the whole reported cycle. It is never a personal probability of admission. It does not become 78 percent for you, or for anyone. An application is read as a whole file, and no single rate published at the institution level predicts what happens to it.

What the rate does tell you honestly is context for reading the score band. When a school admits 78 percent of applicants overall and enrolls 37,806 undergraduates, the reported score range is describing an unusually large and varied group of students. A wide 6-point band and a high overall rate are consistent findings. Neither one is a promise.

Two limits worth being explicit about. First, this data does not tell us how many applicants or enrolled students submitted an ACT score at all, only what the percentiles were among those who did. Second, the rate is a single institution-wide figure, so it says nothing about differences between programs, terms, or applicant groups. Anyone claiming otherwise is filling gaps with guesses.

If you are comparing several schools, put them side by side rather than reading each rate in isolation. Our college ACT scores guide explains how to line up percentile bands across schools without over-reading small differences.

Reading your own composite against 27, 29, and 33

Find your current composite. The right-hand column is a description of position, not a prediction of any outcome.

Two cautions on this table. It cannot tell you whether you will or will not be admitted, because no score band can. And it describes only students who enrolled after submitting a score, which is a narrower group than everyone who applied. Use it to decide whether more prep time is worth spending, which is a question percentiles genuinely can help with. Start with a full timed form from our ACT practice test guide so the number you are placing on this table is a real one.

What a 6-point band means for how you actually study

On the Enhanced ACT 2025 format, your composite is the average of English, Math, and Reading. Science is optional and reported separately, so it does not enter the composite. There is no penalty for wrong answers, which means every question should get an answer.

Because the composite averages three sections, moving it 1 point takes roughly 3 scaled points spread across those sections. Getting from 27 to 29, the width of this school's lower half, is about 6 scaled points total, or 2 per section. Framed that way, the target stops feeling abstract.

One thing nobody can give you: section-level targets for this school. English, Math, and Reading percentiles are not in this data set, so any page publishing an "IU Bloomington Math ACT range" is inventing it. Build your section plan from your own diagnostic instead. See the Enhanced ACT 2025 format guide, how to improve your ACT score, and how superscoring works if you plan to test more than once.

Free Prep36 tools to close a 2-point or 4-point gap

Prep36 is free-first, so the practice comes before any paywall.

• 1,026 original practice questions, all free, with an instant explanation on every answer. These are written by Prep36 and are not official ACT questions.
• 6 full-length timed test forms, 2 of them free, so you can see a composite under real timing rather than guessing at one.
• Free ACT score calculator at /guides/act-score-calculator, which turns raw section counts into a composite estimate.
• Free study plan builder, which lays out what to work on and when.
• Free score forecast, which projects where your current trajectory lands.
• Free Enhanced ACT Cram Kit at /cram-kit for the final weeks.

A workable sequence for this specific band: take one free timed form, put the result on the table above, then decide whether you are chasing the compressed 27 to 29 stretch or the wider 29 to 33 one. Those are different amounts of work and deserve different plans. Our study guide covers the routine, and test dates lets you plan backward from a date you choose. Everything runs in the browser at the Prep36 app.

What this page will not tell you

Being clear about the edges of the data matters as much as reporting it. This page is built from exactly seven facts: the ACT composite 25th percentile of 27, the reported midpoint of 29, the 75th percentile of 33, the 78 percent overall admission rate, undergraduate enrollment of 37,806, and the location of Bloomington, Indiana.

So we are not going to tell you:

• Whether the ACT is required, optional, or considered. That is university policy and it is not in this data.
• Application deadlines or test-date cutoffs for this school.
• Score expectations by major, program, or honors track.
• Scholarship or merit-aid score thresholds.
• English, Math, or Reading section ranges, which do not exist in this data set.
• Whether you will be admitted. No percentile band can answer that.
• How this range has moved over previous years.

For anything on that list, go to the university's own admissions pages, which are the only authoritative source for policy and dates. Use this page for what percentile data is genuinely good at: telling you where a score sits relative to a cohort, and helping you judge whether the next 2 points are worth the study hours.

What these composites cost in raw questions

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.

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 27 and a 33 in each section, whoever you are aiming at. Build your own section goals from your own practice results.
