North Dakota’s most recent high school graduates had the fourth-highest ACT test scores among the 19 states that require students to take the test.

The ACT is an entrance exam used by most colleges and universities to make admissions decisions. The test measures a high school student’s readiness for college, and provides colleges with a standardized score that can be used to compare all applicants.

The highest possible ACT score is 36. The national average is 20.

In rankings of the percentage of students who were judged college-ready in the four tested subject areas, North Dakota high school students came in second in reading, third in math, fourth in science and fifth in English.

North Dakota’s composite ACT score has remained the same for the past three years, while the national composite test score has been dropping.

The three states ahead of North Dakota’s composite ACT score of 20.3 are Minnesota (21.3), Wisconsin (20.5) and Utah (20.4)
