What is a 27 ACT score?

A 27 ACT composite ranks at the 89th percentile nationally, meaning about 89% of recent ACT-tested high school graduates scored at or below a 27. That is ACT's own national rank for tests taken between September 2026 and August 2027.

A 27 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 27 in each scored section allows roughly 30 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 27 actually stands at real colleges.

What a 27 costs in questions

A 27 in each of English, Math and Reading means getting roughly this many right, and no more than this many wrong:

That is 30 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 27

A composite is the average of English, Math and Reading, so the same 27 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.

All four routes land within 3 questions of each other, so at a 27 the shape of your score matters much less than the total. Play to whichever section is already strongest.

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 27 to 30

Three more composite points is 11 more questions right in total: English 4, Math 5, Reading 2.

Framed as points it sounds like a different student. Framed as 11 questions it is a number of weeks of specific work, which is what it actually is.

Where a 27 stands at the colleges Prep36 covers

Of the 45 colleges with score data on this site, a 27 sits at or above the top quarter at 4, inside the middle 50% at 25, and below the bottom quarter at 16.

At or above the 75th percentile

• Oklahoma State University 20–27
• Brigham Young University-Idaho 20–26
• Kennesaw State University 19–26
• West Virginia University 20–26

Inside the middle 50%

• Purdue University 27–34
• University of Texas at Austin 27–33
• Indiana University-Bloomington 27–33
• University of South Carolina-Columbia 26–32
• University of Minnesota-Twin Cities 26–31
• Oregon State University 24–31
• and 19 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 27

The conversion curve is not evenly spaced. At a 27 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 English, where one more correct answer moves that section 1 point. You currently have the most margin in Math (14 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.
