The American College Test or ACT is a standardized college admission test that measures the student’s abilities in the core subjects taught in high school. ACT helps to impartially assess a student's potential for success in college and assist colleges in admission by providing a standardized measurement of the ability of students from different schools across the world.

Individuals with different educational backgrounds and ages can take the ACT, including middle school students, high school graduates, and adults who want to return to college. A student can take the ACT more than once and select the scores to be sent to colleges for review.

ACT is a three and a half hour test and has four mandatory subject tests- English, Reading, Mathematics, and Science, and one optional 30 minute Writing. The test has 215 questions.
