ACT vs SAT: The definitive guide to help you choose

One of the most common questions that high school juniors and seniors ask is ‘Should I take the SAT or ACT?’. In 2025, over 2 million took the SAT (SAT Annual Report) while nearly 1.38 million took the ACT (ACT Profile Report), so the confusion isn’t surprising.

The preference for the SAT over the ACT (and vice versa) varies even across bordering states. In the senior class of 2025, Texas, New Mexico, and Colorado have more SAT takers, while their neighboring states Missouri, Kansas, Arkansas, and Louisiana have more ACT takers (Wikipedia).

Before we compare the SAT and the ACT, it’s important to look at their similarities. Both are standardized tests evaluating college-readiness and both have math sections and reading passages. Also, neither of the tests penalizes students for wrong answers. 

This article begins by studying the key differences between the SAT and the ACT. Next, we compare the sections of the SAT and ACT. We then examine how each test reports their standardized test scores. Finally, we conclude by helping you decide which of the two you should write.

SAT vs ACT: Key Differences

The following table highlights all the important differences between the SAT and the ACT.

The image below captures the principal differences between the SAT and ACT exams:

What is the SAT?

The SAT is a standardized test for college admissions. Anyone hoping for college admission in the USA may take the test, irrespective of where they are currently based.

The digital SAT is adaptive. It is conducted only on designated devices; the pencil-and-paper version was phased out in March 2022. 

It comprises two sections: the Reading and Writing section, and the Math section. Each section is divided into two sub-sections called modules. It is a multi-stage adaptive test, which means that the questions a student gets in the second module depend on their performance in the first module.

Although not mandatory, most colleges consider the SAT scores an important component of the admission process. It has been held since 1926, and a not-for-profit body called the College Board owns and conducts it.

Advantages of the SAT

Here are some of the advantages of the SAT:

• If you get a good score on the SAT, your chances for college admission improve considerably even if your bio-data isn't strong otherwise. Learn more about SAT scoring here.
• There is clear evidence that preparing for the SAT improves SAT scores.
• It's a standardized test, so everyone competes on a level playing field.

Disadvantages of the SAT

Against the advantage mentioned above, there are some of the disadvantages of the SAT:

• It may not assess all your skills correctly.
• Using only the SAT scores to determine college-worthiness can be faulty.
  ‍

What is the ACT?

Originally known by its full name American College Testing, the test is currently known only as the ACT. It is one of the two major tests whose scores are an important component for university admissions, including test-optional colleges. 

Unlike its counterpart (the SAT), the ACT is linear and not adaptive. That means the questions on the test are fixed and do not vary based on your performance. In such tests, students sometimes feel less stressed because they don’t have to worry about the first module impacting their second module.

As of today, the ACT is conducted over computers only at international locations. Within the USA, test-takers can choose whether they'd like to go for the pencil-and-paper version or the digital version. It comprises three compulsory sections, each of which will be scored between 1 and 36.

Tutors can explore how they use a powerful ACT test prep platform to better help students.

Advantages of the ACT

Below are the advantages of taking the ACT:

• Till the ACT switches over to the digital model completely, students have the choice to decide between taking the pencil-and-paper version and the digital version.
• If your math skills are not particularly good, you might fare better with the ACT. You can find more ACT test tips here.
  

Disadvantages of the ACT

The ACT has its limitations too. Here are the two principal ones:

• Because it's not adaptive (not yet, at least), the ACT doesn't reflect the skill levels of all the test-takers with full accuracy.
• Fewer students take the ACT than take the SAT. Hence, you'll find fewer test-prep resources too.

SAT vs ACT: Key differences in exam sections

The differences between the SAT vs ACT go well beyond the number of questions or time available. Below is a detailed comparison of the differences in the sections of two tests.

Differences in the SAT and ACT Math sections

First, a simple fact: Some of the SAT questions are student-produced response questions, while the ACT has only multiple-choice questions. 

Now let’s see how it impacts your test-taking strategy. Below are two screenshots; the first is a question from the ACT practice questions for math, while the second is from the SAT official practice test.

‍

You’ll see that both questions test almost identical skills: solving an algebraic expression. But there’s a fundamental difference.

In the case of ACT, you have answer choices. So if you can’t think of anything else, you can simply plug the given value (in this case, the value of “x”). Whichever satisfies the expression is the correct answer. 

With the SAT, there are no choices given. So the only way to get the correct answer is to solve the expression.

Of course, under the latest SAT structure, most SAT questions are multiple-choice questions, so this difference isn’t always a deciding factor. However, the absence of answer choices can turn an easy question into a moderately difficult question.

Besides this, there are other differences between the ACT math and SAT math sections. For instance, the ACT covers more syllabi, but the questions mostly test math concepts. The SAT, on the other hand, will involve more reading and thinking skills, so you’ll need to stop for a while and think through the question before you freeze your answer choice.

Reading and Writing Section: Key Differences between the ACT and the SAT

While both the SAT and the ACT assess the student’s linguistic skills, the nature and goals of their questions are slightly different. The ACT passages, for instance, are nearly five times as long as the SAT passages. That means students taking the ACT will have to develop the ability to read and understand longer passages.

Let us take up a few official ACT and SAT questions to see how the two are different.

The screenshot above juxtaposes two different ACT reading questions. The one on your left requires you to not only take a broad view but also apply strong thinking skills. You need to understand the passage from a larger perspective and then extrapolate beyond what is directly stated. You’re unlikely to answer this question correctly without reading the entire passage.

Against that, the question on your right asks you about a particular detail (in this case, the McNaghten case). You can scan the passage quickly, spot the particular case, and answer the question. You don’t need to read the entire passage.

Now see the SAT question below

While the above SAT question also asks about the passage in general (“main purpose of the text”), there are only a few lines you need to read and understand. Because the text is short, you can read and re-read it till you’re sure you’ve found the answer.

The details are right there; no need to spend time looking for the right information. It’s just that you might need longer to think and eliminate the wrong choices.

So this is what it means. Because the ACT reading section has long passages, you’ll need to carry more information in your mind while you answer certain questions. In contrast, the SAT has shorter text to read but it can often be pithier. 

In the strictest sense of the word, some students feel that the SAT Reading and Writing section should be called the Reading section in the SAT. That’s because the SAT optional essay section has been removed, so there’s no writing per se in the SAT. In contrast to that, the ACT has a writing section, albeit optional.

Experimental or pretest questions

ACT vs SAT: Score Conversion

Although the two tests are considerably different, their overall purpose remains the same: assessing a student’s college-readiness. Hence, their scores need to be comparable at some levels. 

The ACT has a concordance table which shows what SAT scores are equivalent to what ACT scores. You can see section-wise conversion as well as composite score conversion.. Here is the table:

SAT vs ACT differences: What they mean to you

Okay, now you have enough information to compare the SAT and the ACT. But how do these ACT vs SAT differences impact your selection of tests and your test-taking strategies?

Let’s look at the five most important areas:

1. Time per question

The SAT gives you 2 hours 14 minutes for 98 questions: an average of 82 seconds per question.

Against that, the ACT has 2 hours 05 minutes for 171 questions; an average of 42 seconds per question.

The SAT gives you almost double the time as the ACT. 

If you’re someone who needs more time to think, you’re probably better off with the SAT. On the other hand, if you’re better at quickly moving from one question to another, taking the ACT might be a good idea for you. 

2. The Math section

On the SAT, the Math section contributes to 50% of your total SAT score. Against that, only 25% of the total ACT score comes from the Math section.

The message is clear: if Math isn’t your strong point, ACT is the test you want to write. On the other hand, if you are confident dealing with math questions, you’ll probably want to take the SAT.

3. Reading passages

The reading passages on the digital SAT are very short and each question corresponds to a different passage. Against that, the ACT passages are longer, and each passage is used for multiple questions.

While both tests evaluate your reading skills, they do it differently. Reading longer passages would require you to focus on the same passage for a much longer duration. The ACT has more questions - slightly easier too - but allows less time per question than the ACT. If that’s your strength, you’ll have an edge in the ACT. 

Not a quick reader? You’ll be more comfortable with the SAT.

4. Perfect scores

The total SAT score is the simple total of your scores in both sections. Against that, your composite ACT score is the simple average of your scores across the four sections.

This might seem a bit paradoxical but it’s possible to achieve a perfect composite score of 36 on the ACT even if you didn’t get 36 on each section. That’s because the average will be rounded to the nearest whole number. You can find what the average ACT scores here.

In the SAT, you can get a perfect 1,600 only if you score an 800 on both sections. 

5. Other factors

As mentioned above, the ACT has more questions, but they are slightly easier. The SAT uses fewer questions but that raises the importance of individual questions.

The SAT math questions involve more thinking and reasoning when compared to the ACT. Those of you who would rather stick to the core concepts find ACT easier.

Further, because of a larger number of questions, you have a slightly larger margin for taking chances in the ACT. You can get up to six or seven questions wrong and yet achieve a perfect score. In the SAT, if you have more than three incorrect answers, it’s unlikely you can reach the perfect score. 

Which test should I write, the SAT or the ACT?

If you are a tutor, your students shouldn’t waste time trying to answer questions like ‘Is the SAT easier than the ACT?’ or ‘Do colleges prefer the ACT or the SAT?”. Even after the latest changes in the ACT, there’s no one-size-fits-all answer: what’s a great choice for Isabella may not be even half as good as her best friend Ron. 

Answers to such questions are highly personalized, so it’s best to first speak to an admission expert. They will have all the tools and experience to guide students to make the right decision. 

Alternatively, you can simply sign up and see for yourself how Edison can help your students and scale your own tutoring business. You have a 30-day trial, so that will give you more than enough time to explore and decide. 

Whatever the case, the most important thing is to take action. Do it now

Do Colleges Prefer SAT or ACT?

Most colleges and universities do not prefer the SAT over the ACT, or vice versa. Admissions offices focus on how well a student performs relative to the test they choose. Both exams are treated equally in the admissions process, and schools use standardized test scores as one of many factors when reviewing applications.

Therefore, a strong SAT score and a strong ACT score carry the same weight, as long as they meet the institution’s expectations.

Many colleges are also test-optional, meaning students may choose whether or not to submit SAT or ACT scores. However, for students who do submit scores, colleges evaluate them using the same benchmarks and scholarship criteria regardless of the test.
