COLUMBIA, S.C. (AP) -- South Carolina's graduating seniors saw slight improvement on their ACT college entrance exam scores for a fourth consecutive year, but the state's average on the exam's four tests remains lower than the national score.
Results released Wednesday show the average score for public, private and home school graduates was 20.2 on a 36-point scale. That's up from 20.1 last year, 20 in 2010 and 19.8 in 2009.
South Carolina's composite score is 0.9 points below the nation's average.
Nineteen percent of test-takers earned scores indicating they're ready for college in English, reading, math and science. That compares to 25 percent nationwide.
Both the ACT and SAT are accepted by most colleges. The SAT is historically more popular in South Carolina.
More than 21,100 graduates took the ACT this year.
