@MYOS1634 : Yes, 28-30 is “quite good,” but when I take a look at the CDS for my alma mater, a liberal arts college that’s also “quite good,” I see that for the most recent year 77% of the enrolled first-year students scored in the 30-36 range on the ACT, 22% in the 24-29 range, and 1% in the 18-23 range. This is not the distribution for ADMITTED students (and it doesn’t speak to the admit rate), but it tells me that if I’m applying I would want to score 30 or above.
My only suggestion above was that it would be worthwhile for this applicant to retake the ACT to assure a score of 30 or more. Test scores of course aren’t necessarily decisive – and some very good liberal arts colleges have first-year students with a smaller percentage at 30+ (e.g., Kalamazoo College: 43% scored 30-36 on the ACT).
