What a 27 ACT score means on the SAT scale

On the concordance table published jointly by ACT and College Board, an ACT composite of 27 corresponds to an SAT total of 1280. Because one ACT point spans several SAT points, the table also gives a range, 1260–1290, and colleges treat any SAT score in that range as equivalent to a 27. An SAT 1280 is good: the 83rd percentile of SAT takers, or the top 17%. ACT publishes its own percentile tables for the composite, which differ slightly because the two tests are taken by different groups of students.

Which colleges a 27 fits

Admissions readers compare test scores with the middle-50% range of admitted students, published for both tests in each college’s Common Data Set.

One ACT point in SAT terms

Moving from a 27 to a 28 is worth about 30 SAT points (1310), and a 26 concords to 1240. Near the top of both scales each ACT point covers a wider SAT range, which is why a 34 and a 35 look similar to a college that reads scores in SAT terms while a 20 and a 21 sit only about 40 SAT points apart.
