What colleges can you get into with a 21 ACT?
A 21 ACT is a below-median score, under the admitted middle at most four-year colleges, though many schools stay realistic. On the official ACT-SAT concordance it is roughly equivalent to a 1080 SAT, so the lists below are built from the same real admitted-student data, sorted into safety, target, and reach. For your actual odds, the free calculator folds in your GPA, course rigor, and activities too.
For example, a 21 ACT is a strong match at Bismarck State College, a likely safety at Clark Atlanta University, still a reach at Southern Wesleyan University.
Safety schools
56 schools where a 21 ACT your score clears the admitted middle, so academics are unlikely to be what holds you back.
Target / Match schools
347 schools where a 21 ACT your score sits right in the competitive admitted range.
Reach schools
404 schools where a 21 ACT your score is below the admitted middle, so the rest of your profile has to carry more weight.
High reach schools
287 schools where a 21 ACT admission is a long shot on scores alone; these stay reaches for almost everyone.
What safety, target, and reach mean here
How these tiers are built, and where the concordance comes in.
Because colleges report admitted SAT more consistently than admitted ACT, each school is placed using its admitted 75th-percentile SAT and your ACT's concordant SAT (a 21 ≈ 1080), then adjusted for selectivity. A safety means your score comfortably clears the admitted middle; a target means it lands in the competitive range; a reach means it is below the middle, so the rest of your application carries more weight. The most selective schools stay reaches at every score. These are planning bands, not probabilities. The percentage chance is computed, per school, by our transparent model in the calculator (method on the methodology page). Prefer the SAT? See the 1100 SAT lookup.
Frequently asked questions
Is a 21 ACT a good score?
A 21 is a below-median ACT, under the admitted middle at most four-year colleges, though many schools stay realistic. On the concordance it lines up with about a 1080 SAT, so it opens 403 realistic options across the 1,100+ colleges we track. It is best matched to schools with higher acceptance rates, and a retake can move it meaningfully.
What colleges can I get into with a 21 ACT?
A 21 is a safety-level score at 56 schools and a target/match at 347 more, for 403 realistic options. The tiered lists on this page name them, and the calculator estimates your specific odds once your GPA, rigor, and activities are included.
Should I submit my 21 ACT or take the SAT instead?
Colleges accept both equally, so submit whichever is stronger on the concordance. A 21 ACT is about a 1080 SAT, so compare against that. Many colleges also superscore, combining your best section scores across test dates, and many are test-optional, in which case a strong GPA and rigor can carry the application.
Is a 21 ACT enough for top-20 schools?
The most selective schools admit students with ACTs roughly in the 34-36 range, so a 21 would sit below their admitted middle. They stay reaches, but a strong GPA, demanding courses, and a distinctive profile matter more than the test alone.
