How are the SAT and ACT Scored?

Before trying to interpret the scores, you need to understand how each test is scored. The SAT has two sections, Reading and Writing, and Math. Each is worth up to 800 points, so your total score is out of 1600.

The ACT has three scored sections that feed your composite: English, Math, and Reading. Each is scaled from 1 to 36, and those three are averaged to give you a composite out of 36. This changed in 2025. Science used to be the fourth section in that average; it is now optional, and if you take it, it is reported on its own and also combines with Math into a separate STEM score. Optional Writing is reported separately too, on a 2 to 12 scale.

What is a Perfect Score?

Don’t beat yourself up if you didn’t get a perfect score! Only about ~0.03% get a perfect score of 1600 on the SAT and about ~0.01% get a perfect score of 36 on the ACT. Our founder Kalyan Ray-Mazumder who wrote the curriculum for Prepmedians is one of the few people I know who got a perfect score on the test.

The top tier American colleges like the Ivy-League schools are looking for scores above the 90th percentile. For the SAT, the 90th percentile score is approximately 1350 and for the ACT, the 90th percentile score is approximately 28.

While a less than perfect score doesn’t dictate your chances with the top colleges and universities, a perfect score doesn’t determine your odds of getting in. There have been a lot of cases where students who have scored perfect scores, even multiple times, still were not able to get into some of the top tier schools. So, if the score you expected was not the score you got, don’t be disappointed.

High SAT or ACT Score

When interpreting SAT scores, know that the average total score has sat right around 1050 for years, split roughly evenly between the two sections. Scoring above 1050 puts you in the top half of test-takers. The ACT composite average has drifted down and now sits around 19 to 20, so scoring above 20 puts you in the top half there. Because the ACT composite no longer includes Science, do not assume a composite from a 2024 chart maps perfectly onto one earned today.

While there is no one ideal score, you want to interpret the scores based on how selective the colleges in your list are. A 1200 or higher, along with other excellent application factors, should gain you admittance into many highly regarded American colleges. Depending on all the other factors of your application, an average score won’t keep you out of a good school.

What’s the Worst Score?

The low end for the SAT is a 400, and the lowest possible ACT score is 1.

You have to work pretty hard to get a score that bad. Even if you don’t answer a single question, the companies that administer the tests are more likely to throw out your test, assuming an error was made, than to actually send it to any colleges.

The question has been asked many times whether merely entering your name gets you the minimum SAT and ACT scores, and there seems to be no definitive answer.
