ACT has designed benchmarks that identify the scores needed by a student taking its test which indicate that student would have a 50% chance of earning a B or better in college or a 75% chance of earning a C or better.
Results of the percentage of students for the 2013 test which show how many of those graduating seniors met the benchmarks in certain subjects are in:
54% of high school grads met the benchmark in English,
44% in reading,
44% in math, and
36% in science.
31% of 2013 grads met none of the benchmarks, and only 26% met all four benchmarks.
Overall ACT scores have dropped from 2009 to 2013, but the pool of ACT test takers has increased during those years.
It looks like students planning to continue on in college need to study more or consider alternatives to college.
