Short answer: A 'good' ACT score depends on the target college, but as a general guide: 21+ is above the national average, 24+ puts a student in the top 20% nationally, 28+ is competitive for most selective schools, and 33+ is where the most selective national universities expect applicants to land.
Key takeaways
- The national average ACT composite is around 19.4, so scores above 21 are already ahead of most test-takers.
- Students can take the ACT up to 12 times, and most colleges superscore across attempts.
- Score goals should be set against specific target colleges, not a generic national benchmark.
- A score gap of 4 or more points usually benefits from structured tutoring rather than self-study alone.
How the ACT is scored
The ACT composite is the average of four section scores (English, Math, Reading, Science), each scored 1-36. The optional Writing test is scored separately, 2-12, and doesn't factor into the composite.
What is the average ACT score?
The national average composite is approximately 19.4. On a percentile basis, a score of 19 sits right around the 50th percentile, meaning it's roughly the middle of all test-takers nationally.

ACT score goals by grade level
Underclassmen have more runway to build toward a target score gradually, while juniors and seniors benefit from setting a specific number tied to their actual college list, then working backward to figure out the realistic prep timeline needed to get there.
Setting a target score for your child
- Pull the middle-50% ACT range for each school on the current college list.
- Aim for the top half of that range if merit scholarships are part of the goal.
- Run a diagnostic test to see the current starting point.
- Build a realistic timeline based on the size of that gap.
Can your child retake the ACT?
Yes, up to 12 times total, though most students only need two or three attempts. Since most colleges superscore, combining the best section scores across multiple sittings, a retake focused on the weakest section from the first attempt is often the most efficient path to a higher composite.
