What Is the Lowest ACT Score? (2026)

The lowest possible ACT Composite score is 1. Here's how the scale's floor works, what a 1 means for percentiles and college, and how to climb out of a low score.

The lowest possible ACT score is 1. The ACT Composite is reported on a scale that runs from a minimum of 1 to a maximum of 36, so 1 is the absolute floor. If you just got back a very low score, are bracing yourself before test day, or are simply curious how the bottom of the scale works, this guide walks through what a 1 means, how rare it is, and what you can do about a low score.

The Lowest Possible ACT Score Is 1

Every section of the ACT is scored on a 1 to 36 scale. On the current enhanced ACT, those sections are English, Reading, Math, and Science, and each one can fall as low as 1 or climb as high as 36. The one exception is the optional Writing test, which uses a separate 2 to 12 scale rather than 1 to 36. According to ACT's official explanation of how scores work, both the individual sections and the Composite share the same 1 to 36 range.

Your Composite score is the headline number colleges usually look at, and it is simply an average of your section scores rounded to the nearest whole number. Here is the important 2025 update: on the enhanced ACT, the Composite is the average of just three sections, English, Math, and Reading. Science is now optional, and even when you take it, it is reported separately and does not count toward your Composite. (It does feed a separate STEM score alongside Math, but that is a different number.) Older guides that average all four sections, including Science, are out of date, so be careful which math you trust.

Because the Composite is an average of numbers that each bottom out at 1, the lowest a Composite can possibly be is 1. To land there, you would need to score 1 on English, 1 on Math, and 1 on Reading. The rounding rule is straightforward: fractions below one half round down, and one half or more rounds up. So the floor of the whole scale is 1, and there is nothing below it. If you want a full breakdown of every possible value, our guide to the ACT score range covers it from 1 all the way to a perfect ACT score of 36.

What Percentile Is a 1 ACT Score?

A Composite of 1 sits at the very bottom of the scale, at roughly the 1st percentile or below. Percentiles, which ACT calls national ranks, tell you the share of recent graduates who scored at or below your number. Per ACT's national ranks data, every Composite from 1 through 5 carries a national rank of 1, meaning about 1 percent of recent test takers scored at or below that level. In other words, a 1 is statistically about as low as results get.

Here is how a handful of low Composites map to their approximate national rank so you can see how quickly the percentile climbs as the score rises.

The takeaway is that scores in the single digits are extremely uncommon, and even a modest jump out of the bottom range moves your percentile up fast. For a deeper look at how the whole curve behaves, see our full breakdown of ACT percentiles.

Can You Fail the ACT?

No. There is no official passing or failing ACT score. ACT does not designate any score as a pass or a fail, so a low number is never a formal failure the way it would be on a class final. Instead of a pass line, ACT publishes College and Career Readiness Benchmarks, which estimate whether you are likely ready for typical first-year college courses. Those benchmarks are guidance about readiness, not a threshold you have to clear to "pass" the test.

What actually matters is each college's own expectations. Schools set their own score ranges, and those vary enormously, from highly selective programs to open-admission colleges that admit nearly every applicant. On top of that, the test-optional movement means a large number of US colleges no longer require an ACT or SAT score at all. If a school is test-optional, a low score does not have to be part of your application. So while a 1 is the lowest the scale allows, it is not a failing grade, and it does not automatically close every door. If you want a sense of where the bar sits for strong applications, our guide on what counts as a good ACT score is a useful reference point.

What a Very Low ACT Score Means for College

A very low ACT score narrows some options, but it rarely eliminates a path to college entirely. Here is how to think about it realistically.

• Open-admission and community colleges. Many community colleges and open-admission schools accept students regardless of test score. They often use placement testing rather than the ACT to decide which courses you start in, which means a low Composite need not block enrollment.
• Apply test-optional. Because so many colleges are now test-optional, you can frequently choose not to submit a score that does not represent you well. Check each school's policy, and if it is test-optional, let the rest of your application speak for you.
• Lean on your GPA and the rest of your file. Grades over four years, your course rigor, essays, recommendations, and activities all carry weight. A strong transcript can do a lot of work that a single test score cannot.
• Retake the test. A low score is a snapshot, not a verdict. Many students improve substantially on a second or third sitting, especially once they have seen the format and built a study routine. You are allowed to retake the ACT, and most schools consider your best result.

For context on where a typical applicant lands, our guide to the average ACT score shows how much room there usually is between a very low score and the national middle. And if your current score is in the high teens, whether 20 is a good ACT score puts the nearby range in perspective.

How to Raise a Low ACT Score

If your score came back low, the encouraging news is that the bottom of the scale is also where improvement comes fastest, because there is so much room to grow. Here are concrete, doable steps.

1. Start with one section at a time. Since your Composite is the average of English, Math, and Reading, lifting even one section meaningfully nudges the average up. Pick the section where points come easiest for you and build momentum there first.
2. Practice with real, timed questions. The ACT rewards familiarity with its format and pacing. Working through authentic questions under time pressure trains both your content knowledge and your speed. You can practice real ACT questions on Larry Learns to get used to the real thing.
3. Review every mistake, not just your score. The fastest gains come from understanding why an answer was wrong, spotting the pattern, and fixing it. Keep a simple log of recurring mistakes and revisit it before each practice session.
4. Build a steady study plan and retake. A few focused weeks of consistent practice beats one frantic cram. Our guide on how to prep for the ACT lays out a sensible routine you can follow before your next sitting.

Remember that the national average Composite for the most recent graduating classes is about 19.4, well within reach of steady, structured practice from a low starting point. You do not need to chase a perfect 36 to open up real options. You just need to move toward the middle of the scale, and that is very achievable.

Frequently Asked Questions About the Lowest ACT Score

What is the lowest ACT score you can get?

The lowest possible ACT Composite score is 1, because the entire scale runs from 1 to 36. Each scored section also bottoms out at 1, and since the Composite is an average of those sections, it cannot go below 1.

Can you score a 0 on the ACT?

No. There is no 0 on the ACT. The minimum value for any section and for the Composite is 1, so 0 is not a possible score. The lowest you can receive is a 1.

What is the lowest score for each ACT section?

English, Reading, Math, and Science are each scored from 1 to 36, so 1 is the lowest possible score on any of those sections. The only exception is the optional Writing test, which is scored on a 2 to 12 scale, making 2 its minimum.

Is a 1 on the ACT a real score?

Yes, a 1 is a real and valid Composite, and it sits at roughly the 1st percentile, meaning almost everyone scores higher. It is extremely rare, but it is a legitimate point on the scale rather than an error.

What is the average ACT score for contrast?

The national average ACT Composite for the most recent graduating classes is about 19.4, according to ACT's profile report. That gives you a sense of the middle of the scale, far above the floor of 1 and well within reach with focused preparation.
