Almost every week, a parent asks me some version of the same question: "What is a good ACT score?" And almost every week, my honest answer surprises them a little. There is no single number that is "good" for everyone. A good ACT score is the score that opens the doors your son or daughter actually wants to walk through. A 24 can be a fantastic score for one student and a disappointing one for another, depending entirely on where they are applying and what they need it for.
So instead of handing you a magic number, let me walk you through how to figure out the number that matters for your family. Once you see how the scoring works and how colleges actually use it, the whole thing becomes a lot less mysterious.
How the ACT Is Scored
The ACT gives you a composite score from 1 to 36. That composite is simply the average of your three core section scores, rounded to the nearest whole number:
English, Math, and Reading. These are the three core sections on the enhanced ACT, and they are what get averaged into your composite. There are also optional Science and Writing sections, but most students don't take them, and most colleges don't require them. If a specific program your child is targeting asks for Science or Writing, you'll see it on that school's admissions page. Otherwise, focus your energy on the three that count.
Each section is scored from 1 to 36, and the composite is the average. So a student who scores 28 in English, 24 in Math, and 26 in Reading would have a composite of 26. This matters because it means a single weak section can drag down an otherwise strong composite. When I look at a student's score report, I'm rarely as interested in the composite as I am in the section that's lagging behind, because that's usually where the fastest points are hiding. The official breakdown of how sections and the composite work is worth a look on the ACT's own website.
What's the Average ACT Score?
The national average ACT composite hovers around 19 to 20. That's a useful reference point, because it tells you what "typical" looks like. But average and "good" are two very different things. Here is roughly how the composite scores translate into percentiles, which is what colleges are really paying attention to:
A 20 is about the 50th percentile. This is right around the national average. It means the student scored better than about half of all test takers. Perfectly respectable, and enough for admission to many colleges.
A 24 is roughly the 74th percentile. Now the student is ahead of about three quarters of test takers. This is a strong score that puts a wide range of solid universities in reach.
A 28 is around the 88th percentile. This is a genuinely competitive score, ahead of nearly nine out of ten test takers. It opens doors to selective schools and starts to make scholarship money realistic.
A 30 is about the 93rd percentile. So yes, to answer the question I get constantly: a 30 is a good ACT score. It's an excellent one. A student at 30 or above is ahead of more than nine in ten test takers and is competitive at most selective universities in the country.
A 34 to 36 is the top 1 to 2 percent. This is the range you need for the most selective schools in the country, the ones with single-digit acceptance rates.
The ACT Score Your College Actually Wants
Here's the step most families skip, and it's the most important one. Before you decide what score to aim for, go look up the schools your child is interested in. Every college publishes what's called the "middle 50 percent" range for admitted students, meaning the ACT scores of the middle half of the students they accepted. This is public information, usually one quick search away on the school's admissions page.
If a school's middle 50 percent range is 25 to 30, then a 30 puts your child at the top of their admitted pool and a 27 lands right in the comfortable middle. If the range is 32 to 35, then a 30, which is excellent by any national measure, would actually be below the median for that particular school. Same score, completely different meaning. This is exactly why "is a 30 a good ACT score" has no universal answer. It depends on where it's going.
My advice: make a list of the five or six colleges your child cares about, write down each one's middle 50 percent range, and set your target at or above the top of that range. Aim high enough that admission feels safe rather than borderline, and high enough to compete for merit scholarships, which are often tied directly to test scores.
A Good Score Is Almost Always a Reachable Score
Whenever a parent tells me their child "just isn't a good test taker," I gently push back, because I've watched too many students prove that idea wrong. A low practice score usually doesn't mean a student lacks ability. It means they're out of practice with the specific format, the pacing, and the handful of question types the ACT reuses over and over. Those are learnable, every one of them.
I've seen students move from a 22 to a 27 over a focused stretch of preparation, and I've seen section jumps that are even more dramatic, like a math score climbing ten points because we found and fixed a foundation gap from an earlier class. The ACT rewards familiarity and pacing more than raw brilliance, which is genuinely good news. It means the score is something a student can move with effort, not a fixed measure of who they are. You can see a number of these real gains on our results page.
Not every family can coach this at home, and there's no shame in that. Knowing the ACT well enough to teach it is a specialty in itself, which is why we hire very selectively for test prep and train our tutors specifically to raise scores. When we run our ACT prep course, we spend our time on exactly the things that move the number: pacing drills, the recurring question patterns, and the individual weak section that's dragging down the composite. And there's a second advantage that's easy to overlook. A teenager will often admit confusion to a tutor far more readily than to a teacher in front of the whole class, or honestly, to mom and dad. That willingness to say "I don't get this" is where the real progress starts.
Frequently Asked Questions
Is a 30 a good ACT score?
Yes. A 30 places a student in roughly the 93rd percentile, ahead of more than nine out of ten test takers, and is competitive at most selective universities. Whether it's high enough for a specific school depends on that school's middle 50 percent range, so always check the colleges on your child's list.
What is the average ACT score?
The national average composite is around 19 to 20. Anything above that puts a student ahead of the majority of test takers, though "good" for admissions purposes usually means aiming higher than average and toward the range your target colleges expect.
How much can a student realistically improve their ACT score?
More than most families expect. A jump of three to five composite points over a focused stretch of preparation is common, and individual sections can move even more when there's a specific gap to fix. The ACT rewards familiarity and pacing, both of which respond very well to practice. Just don't wait until the week before the test to start. The earlier you begin, the more the improvements stack up. If you already know the ACT is coming and your child will likely need help, it's worth setting up tutoring early rather than at the last minute.
Should my child take the optional Science or Writing sections?
Only if a school your child is applying to specifically asks for them. Most students don't take the optional sections, and most colleges don't require them. Check the admissions pages of the schools on your list before spending prep time there.
