About half of the states in the USA require the ACT or SAT for high school graduation.

Alabama is one state that requires the ACT. The mean score in Alabama is below 18/36. Wisconsin is another. Its students score on average about 1 point higher than the national average of 19.4/36.

If you prefer states that require the SAT, the mean SAT score of students from Delaware is less than 980/1600, about 50 points below the national average.

I'll leave it to others to argue about whether these exams are rigorous.
