Is 17 a Good ACT Score?

What a 17 ACT score means
A 17 is 1 point under the middle ACT taker (18) and 2.2 under the 19.2 national average. 47 in 100 test takers score 17 or lower, and 53 score higher.
On the enhanced ACT the composite is the average of English, Math and Reading, rounded with halves up, so a 17 needs section scores that add up to at least 50 and at most 52. One point down, a 16 is at the 41st percentile; one point up, an 18 is at the 52nd.
How 17 compares with other ACT scores
ACT reports one national rank per composite: the share of recent graduates who tested and scored at or below it. ACT's national average composite was 19.2 for the class of 2026; a 17 is 2.2 points below it.
| Composite | What it marks | Percentile | SAT match | Points from 17 |
|---|---|---|---|---|
| 17 (you) | Your score | 47% | 930 | |
| 18 | Middle ACT taker | 52% | 970 | +1 |
| 23 | Top quarter of ACT takers starts | 77% | 1140 | +6 |
| 28 | Top 10 percent of ACT takers starts | 91% | 1310 | +11 |
| 33 | Top 2 percent of ACT takers | 98% | 1460 | +16 |

On the SAT, a 17 matches 920 to 950, with 930 as the single value ACT prints beside it. See the 17 row on the ACT to SAT conversion chart or see whether 930 is a good SAT score.
What it takes to go from 17 to 18
To move from 17 to 18, your three section scores must add up to 53 instead of 50: 3 section points in any section. On ACT's National Online Practice Test 2, a 17 on all three sections takes 20 English, 17 Math and 13 Reading answers, 50 of 108; 18 on all three takes 55, about 5 more.
| Section | For 17 | For 18 | More |
|---|---|---|---|
| English | 20 of 40 | 21 of 40 | +1 |
| Math | 17 of 41 | 20 of 41 | +3 |
| Reading | 13 of 27 | 14 of 27 | +1 |

The ACT score calculator shows how far your own sections sit from the next composite; ACT superscores across test dates, and many colleges use the superscore.
Is 17 enough for your colleges?
That depends on the college, so we list no admission ranges. Section C9 of each college's Common Data Set gives the 25th and 75th percentile ACT composites of its enrolled first-year students: at or above the 75th, a 17 is a strength; under the 25th it trails most students, and at a test optional college you can leave it off. Some merit scholarships publish ACT minimums on the college's own aid page, and National Merit uses the PSAT/NMSQT, not the ACT (see what a good PSAT score is).

Is 17 a good ACT score?
A 17 ACT composite is at the 47th percentile of ACT takers and matches a 930 SAT (920 to 950): below the middle ACT taker at 18 and 2.2 points under the 19.2 national average, so it is not a strong score yet, but one point reaches the middle. Whether it is good for you depends on the colleges on your list.
What percentile is a 17 on the ACT?
The 47th percentile on ACT's national ranks for 2024 to 2026 graduates: 47 in 100 test takers scored 17 or lower. A 16 is the 41st. An 18 is the 52nd.
17 ACT to SAT: what does it equal?
920 to 950, with 930 as the single value, on the official 2018 ACT and College Board concordance. It says the two scores carry the same weight; it does not predict an SAT score.
How do I raise a 17 to an 18?
Add 3 section points across English, Math and Reading, so they total 53. On ACT's Practice Test 2 that is about 5 more right answers (55 of 108 instead of 50). Work on your weakest section first.
Should I retake the ACT with a 17?
Usually yes if your colleges report higher scores in their Common Data Set. 19.2 is the national average and 23 starts the top quarter, 6 points up. Find your weakest section with a practice test before the next date.
