The ACT is one of the most popular standardized tests in the country, and its scores are used by colleges and universities to determine whether you are eligible for admission. Once you receive your scores, you may be wondering how you compared to everyone else who took the ACT.

ACT percentile rankings are based on a simple calculation. When you take the ACT, your score is calculated against the scores of all other students who have taken the test at a given time. The lowest possible percentile rank is 1st, which means that you scored better than 99% of all test-takers. The highest possible percentage rank is 99th, which means that you scored better than 99% of all test-takers.

For example, let’s say you scored a 19 (a 19.8 is the national average) on your ACT. That typically means you did better than 53% of test-takers. A score of 28 would be better than 90% of all test-takers.

Other Factors

As a reminder, your ACT score and national rank are a piece of what colleges are looking at when you apply. Each college will be different and there are other factors as well such as GPA, challenging high school curriculum, extra-curriculars, leadership skills, well-written & thoughtful essays, demonstrated interest, letters of recommendation, etc. Get Smarter Prep has tutors available to help guide you through the process.
