University of Massachusetts Amherst reports an ACT composite middle 50% of 30 to 33, with a reported midpoint of 31 and an overall admission rate of 60%. The band is only 3 points wide, and that is the detail worth your attention, because half of the enrolled students who submitted an ACT landed on one of four numbers. Every figure on this page comes from the US Department of Education College Scorecard, IPEDS source, for the most recent reported cohort, and every one of them describes students who enrolled and submitted a score. None of them is a cutoff, and none of them predicts what happens to your application.
Everything below comes from one source: the US Department of Education College Scorecard, drawing on IPEDS, for the most recent reported cohort. Six rows, and each one answers a different question.
| Figure | Value | What it actually says |
|---|---|---|
| ACT composite, 25th percentile | 30 | 25% of enrolled students who submitted an ACT scored 30 or below, so about 75% scored above 30. |
| Reported midpoint | 31 | The midpoint of the reported range. Not a verified median or average. |
| ACT composite, 75th percentile | 33 | 75% scored 33 or below, so roughly the top quarter scored above 33. |
| Middle 50% | 30 to 33 | The span between the two percentiles. Three points wide. |
| Overall admission rate | 60% | Institution-wide, across applicants. Not a personal probability of admission. |
| Undergraduate enrollment | 23,671 | Undergraduates enrolled in Amherst, MA. |
Two structural facts matter more than the values themselves. First, a percentile describes a group that has already enrolled. Nobody set 30 as a floor. It is simply the line beneath which the bottom quarter of enrolled score submitters fell. Second, that group is narrow. Applicants who were denied are not in it. Students who were admitted and chose a different school are not in it. Students who enrolled without submitting an ACT are not in it.
For the general mechanics of how colleges report ranges like this, start with our guide to ACT scores.
A middle 50% of 30 to 33 means half of the enrolled score submitters landed on one of four composites. Tight bands like this one get misread in two opposite directions.
Misread one: a narrow band looks like a wall. It is not. About a quarter of enrolled score submitters came in at 30 or below, and below 30 the scale keeps going for a long way. Those students are in the cohort. The 25th percentile marks where they sit, not a door that closed on them.
Misread two: the top of the band looks like it has room above it. It barely does. Above 33 there are only three composites left, 34, 35, and 36, so the top quarter of enrolled submitters is compressed into three values while the bottom quarter spreads across everything underneath 30. The band is not symmetric, and neither is the work required to move at each end of it.
One more detail about the 31. The arithmetic center of 30 and 33 is 31.5, and the reported midpoint comes in at 31, half a point lower. Do not build a theory on that. It is a reported midpoint, a product of how the range is summarized, not a verified median, and it cannot tell you where inside 30 to 33 enrolled students actually clustered.
These two numbers get read as a contradiction. A 60% admission rate sounds forgiving. A 25th percentile of 30 sounds strict. Both are accurate, because they measure different populations at different moments.
The 60% is institution-wide. It pools applicants to the whole university into one ratio for one reported cohort. It is not a probability attached to you, and nothing in this data set breaks it down any further, so any claim about your odds, your intended program, or your profile would be invention rather than data.
The 30 to 33 band measures a smaller and later group: students who enrolled and who submitted an ACT. That group has already been filtered twice, once by admission and once by their own decision about where to attend. Its scores describe who showed up, not what it took to be admitted.
Scale is worth holding in mind as well. With 23,671 undergraduates enrolled in Amherst, the cohort standing behind these percentiles is large, and a large cohort holds more variety than a 3-point summary can show. A moderate institution-wide rate and a high, narrow score band can sit side by side without either being wrong. To compare bands like this across a full college list, see college ACT scores.
Take your most recent full-length practice composite, not a single section score and not a guess, and set it next to the band. Three cases cover most readers.
Whatever your number is, do two things with it. Convert raw counts into a composite properly with the free ACT score calculator, so you are comparing like with like instead of eyeballing a total. Then run the free score forecast in the Prep36 app to see what your current baseline actually supports. Neither tool says anything about admission. They describe the test, which is the part of this you control.
On the Enhanced ACT the composite is the average of English, Math, and Reading. Science is optional and reported separately, so it never enters the composite these percentiles describe. That makes the band easy to convert into the scale you actually practice in.
| Composite | Implied total across English, Math, Reading | Distance from the 25th percentile |
|---|---|---|
| 30 (25th percentile) | 90 | Baseline |
| 31 (reported midpoint) | 93 | 3 section points |
| 33 (75th percentile) | 99 | 9 section points |
So the whole 3-point band is 9 scaled section points wide, and one scaled point in one section is worth a third of a composite point. Getting from 30 to 31 can come from one section improving by three, or from all three improving by one. Getting from 30 to 33 is a different project entirely: an average of three scaled points in every section, with no weak section left to carry.
The format you are converting from matters too. English is 50 questions in 35 minutes, Math 45 in 50, Reading 36 in 40, and optional Science 40 in 40. There is no penalty for a wrong answer, so a blank is pure loss. The specifics are in the Enhanced ACT 2025 guide, and if you are weighing two sittings, read how superscoring works before assuming how any particular school treats it.
You cannot plan against a band without a real baseline, and a baseline should not cost you anything. This order works.
For method rather than tools, how to study for the ACT covers building the routine and how to improve your ACT score covers closing a gap. Check test dates before you commit to a plan length. Nothing here promises a score, and 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 30 | For a 31 | For a 33 |
|---|---|---|---|
| English 50 questions | 45 of 50 miss up to 5 | 45 of 50 miss up to 5 | 46 of 50 miss up to 4 |
| Math 45 questions | 36 of 45 miss up to 9 | 37 of 45 miss up to 8 | 39 of 45 miss up to 6 |
| Reading 36 questions | 31 of 36 miss up to 5 | 32 of 36 miss up to 4 | 33 of 36 miss up to 3 |
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 30 and a 33 in each section, whoever you are aiming at. Build your own section goals from your own practice results.
