How is the ACT Graded?

The ACT is graded on your abilities in the four sections of the ACT. Each section receives a score of 1 – 36, and then the average of those four scores results in your Composite.

Here are some facts you should know about how the ACT is scored:

  • The ACT does not deduct points for incorrect answers. This means you should guess on questions you don’t know the answer to – there is no penalty for guessing!
  • The ACT counts the questions you got correct. This raw score is converted to “scale scores.”
  • The Composite Score is rounded to the nearest whole number.

The ACT Writing is Not Included in Your Composite Score

While you may have opted for the ACT Writing section, this score will be kept separate from your Composite score and is graded differently compared to the other sections. Here, the highest possible score is 12, and the lowest is 2. There are also four domain scores (2 – 12), which are Ideas and Analysis, Development and Support, Organization, and Language Use and Conventions.

What is the Average ACT Score?

Although the highest score on the ACT is a 36, the average ACT score among students in the United States in the 2023-2024 reporting year was 18.5. The average ACT scores for the individual sections are:

  • English: 17.75
  • Mathematics: 17
  • Reading: 19.4
  • Science: 19

What is the Average ACT Score to Get Accepted to College?

The average ACT score to get accepted to college depends on the college in question.

More competitive schools tend to accept students who have higher ACT scores. On collegeraptor.com, each individual school page highlights the 25th and 75th percentile scores for accepted students if the college reports these numbers.

Students looking to apply to these schools should note the highest ACT scores as this could increase their chances of getting an acceptance letter. Some colleges and universities will look for the max ACT score from their students!

As an example, we’ve highlighted the 75th and 25th percentile scores for accepted students in 2022 at Harvard University, Boston College, and Babson College.

Many students also received a 36 on their individual section scores:

  • English: 11,716 students

  • Reading: 24,857 students
  • Science: 7,918 students

Tips to Get Your Highest ACT Score

If you’re aiming for a 36, you’re going to have to start early with your prep. Here are some suggestions for trying for a perfect ACT score.

1. Have the Right Approach to Practice Tests

One of the first steps you should take when it comes to ACT prep is taking a practice test. This will help you get a feeling for how the exam works, the types of questions that are asked, and where your strengths and weaknesses lie.

2. Take Your First Practice Test

Before you even study for the ACT, it may be a good idea to take an ACT practice test right out of the gate. See how you do with minimal prep and practice. This will give you direction for the weeks and months to come as you aim for that 36.

3. Identify Your Strengths and Weaknesses

One of the biggest benefits of taking ACT practice tests is the ability to identify your strengths and weaknesses on the exam. Some may find at this point they’re better suited for the SAT, too! But knowing your weaker areas gives you direction on where to study.

After your first practice test, score it. Where did you succeed and where did you do less than expected?

4. Study, Study, Study

Once you know where your weaknesses are, you can start to study. If you did poorly on the ACT math but well on the other three sections,for example, you will want to dedicate more time to Math. That doesn’t mean you should ignore the other sections, however, but comparatively, more effort should be put towards mathematics.

Students can study for the ACT using flash cards, ACT study books, mobile apps, and other resources.

5. Take Additional Practice Tests

In between study periods, it can be helpful to take additional practice tests here and there. This approach will allow you to track your progress. You might even find you’re doing better in math and now reading needs work.

Practice tests should direct your studying approach, but your ACT prep shouldn’t 100% be taken up by practice tests either. You won’t advance much if you’re just taking exam after exam.

6. Always Follow the “Rules” of the ACT

Studying is essential, but it isn’t all there is to the ACT. When taking the practice tests, you should always try to recreate the “real deal.” This means adhering to the rules that you would face on test day: no turning back to previous sections, keeping within time limits, and taking scheduled breaks.

Students actually find while they can tackle the subject matter just fine, they truly struggle with the time constraints. By always taking your practice tests under these constrictions, you can ensure you’re truly ready on test day for anything.

7. Work with a Tutor

Another way to prepare for the ACT is to work with a tutor! This may be someone in your local area, through your high school, or through an online program. They have the experience to help you reach your goals with structured programs.

ACT tutors, however, can be expensive, and aren’t for everyone. Students interested in working with a tutor should compare their options before deciding. Study groups may also be available through schools.

8. Take Your First ACT Early

The sooner you take your first ACT the better. You can even view it as a practice test! This gives you plenty of time to improve your score and aim for the 36, while also getting some experience under your belt.

9. Keep Retaking the ACT

A 36 is unlikely to happen during your very first ACT test! Instead, you will want to keep taking the official ACT to keep trying for the top score. You generally have until the November or December of your graduating year to take the ACT, so between sophomore year and these months, you have quite a few opportunities to sit for the exam!

While most students will not earn a 36 on the ACT, it is possible, but you can’t go into the exam without prep. Practice tests, working with a tutor, and having the right approach to studying will make all the difference, but could make a top score a reality.

Should You Aim for the Highest Score on the ACT?

While getting a 36 on the ACT isn’t impossible, it is difficult. Using the tips above can help you improve your scores, but students should keep in mind that only 0.25% of students receive the max ACT score. Aiming for a 36 is an amazing goal and why not try for it, but don’t beat yourself up if you don’t receive the max score.

If you’re struggling with this goal, it may be a better idea to simply aim for a higher score than you received last time and work from there.

While most students will not earn the highest score on the ACT of 36, it is possible, but you can’t go into the exam without prep. Practice tests, working with a tutor, and having the right approach to studying will make all the difference, and going the extra distance could make a top score a reality.
