What is a 28 ACT score?

A 28 ACT composite ranks at the 91st percentile nationally, meaning about 91% of recent ACT-tested high school graduates scored at or below a 28. That is ACT's own national rank for tests taken between September 2026 and August 2027.

A 28 sits in the middle of the scale, which is where the conversion curve is most forgiving and where whole skills are still worth fixing. Scoring about 28 in each scored section allows roughly 27 wrong answers in total. This page breaks that down per section, shows where the cheapest next point is at this score, and lists where a 28 actually stands at real colleges.

What a 28 costs in questions

A 28 in each of English, Math and Reading means getting roughly this many right, and no more than this many wrong:

That is 27 questions of margin across the three scored sections. Science is reported separately on the Enhanced ACT and does not count toward the composite.

Your composite is the rounded average of the three section scores, so an uneven split can reach the same composite at a different price. This row describes the even case.

Prep36's own estimates from the published scoring information. ACT equates every form separately, so real cutoffs move by about a question either way.

Four ways to build a 28

A composite is the average of English, Math and Reading, so the same 28 can come from very different section shapes. If one section is your strength, the other two carry less. Here is what each shape actually demands in questions answered correctly.

The route matters here. Getting to a 28 through "Reading is your best section" needs 102 correct answers across the three scored sections. Getting there through "Math is your strength" needs 106, which is 4 more questions for the same composite. The curves are not identical, and Math gets expensive fastest near the top.

Raw targets use a representative conversion curve, so treat them as close estimates. ACT builds a slightly different curve for every test form. Science is optional on the Enhanced ACT and is reported separately, so it does not enter the composite.

What it takes to get from 28 to 31

Three more composite points is 10 more questions right in total: English 3, Math 4, Reading 3.

Framed as points it sounds like a different student. Framed as 10 questions it is a number of weeks of specific work, which is what it actually is.

Where a 28 stands at the colleges Prep36 covers

Of the 45 colleges with score data on this site, a 28 sits at or above the top quarter at 10, inside the middle 50% at 26, and below the bottom quarter at 9.

At or above the 75th percentile

• University of Nebraska-Lincoln 22–28
• Iowa State University 21–28
• University of Arkansas 21–28
• University of Iowa 21–28
• University of Kansas 20–28
• University of Kentucky 21–28
• and 4 more

Inside the middle 50%

• Purdue University 27–34
• University of Connecticut 28–33
• Rutgers New Brunswick 28–33
• University of Texas at Austin 27–33
• Indiana University-Bloomington 27–33
• University of South Carolina-Columbia 26–32
• and 20 more

Ranges are the published 25th to 75th percentile composites for admitted students. They describe a class, not a cutoff, and no page can tell you your odds at a school.

Where the cheapest point is at a 28

The conversion curve is not evenly spaced. At a 28 the same single extra correct answer is worth a different amount depending on which section it lands in:

So at this score the cheapest composite point is in Math, where one more correct answer moves that section 1 point. You currently have the most margin in Math (12 allowed wrong) and the least in Reading (7).

The curve is coarsest near the top of the scale, which is why a single question can move a section score by two points there and by one in the middle. These are Prep36 estimates, not a published cutoff.

How to actually close the gap

Prep36 tags all 1,026 practice questions to the ACT reporting category they test, so your wrong answers group into skills instead of sitting as a pile. Every question carries a worked explanation, and the planner assigns one skill a day between now and your test date.
