21 ACT Score: Popular Colleges You Can Get Into

Arizona State and the University of Kentucky both take plenty of students with a 21 ACT, and they are far from your only options. That score matches the national average, so you have a workable starting point and more than 1,200 colleges in range. Hundreds of those schools treat a 21 as a realistic fit, with more where you land comfortably above the usual scores.

How 21 ACT Compares Nationally

  • Percentile: 55th - higher than about 55% of recent test-takers.
  • National average: Above 21 - you're above the typical score.
  • SAT equivalent: ~1080 composite (College Board/ACT concordance).

Is a 21 ACT Score Good?

Yes, a 21 ACT is good enough to give you solid options at familiar public universities. You are not limited to schools nobody has heard of.

Texas State (19-25) and Georgia State (19-26) both enroll students around your score, and Cal State Long Beach (20-26) is in a similar band. Appalachian State (21-27) runs a bit higher, so a 21 is toward the low end of its middle 50%.

Colleges still look at your GPA, essays, activities, and recommendations, so this one number does not decide the whole application.

Well-known publics show up right next to easier backups in the tables below. Arizona State (21-28) and the University of Arizona (21-29) put a 21 at the low end of the middle 50%, so they are realistic targets if the rest of your application is solid.

Should you retake the ACT if you have a 21?

A 21 is usable, but a retake is often worth it. Even a 1 or 2 point bump can move you from the low end of a school's range to a more comfortable spot, and it opens more selective publics. If you have a later test date or a few weeks to prep, taking it again is a reasonable call.

Pros of retaking Cons of retaking
A 1-2 point gain can unlock more selective publics Time away from grades and activities
Moves you off the low end of target ranges Another Saturday of testing stress
Helps at schools that still want scores Gains are not guaranteed without focused prep

Students who prep with a real plan often pick up about 1-2 composite points. Focus on your weaker section, take a couple of timed practice tests, and review the questions you miss instead of only grinding new ones.

You can apply with the 21 you have, or spend a few weeks prepping and try for a higher composite.

21 ACT to SAT Equivalent Conversion

Colleges use concordance tables to compare SAT and ACT scores. The following table shows the 21 ACT to SAT equivalent and nearby scores for context. These conversions are approximate.

ACT Score SAT Equivalent
18 970
19 1010
20 1040
21 1080
22 1110
23 1140
24 1180

Individual colleges may interpret scores slightly differently, so treat concordance as a guide rather than an exact rule.
