If you’re planning on completing the ACT for your college applications, one of your main inquiries is likely ‘how long does the ACT take?’ There are actually three different timing lengths for the test itself, depending on whether you include the optional sections. On test day, students spend about four hours at the testing center from start to finish, regardless of whether they complete the writing section or not. Find out the details of how long each section is and how to plan your ACT test day schedule.
Detailed Breakdown of the ACT Test Duration
The ACT is divided into three main multiple-choice parts, plus two additional optional parts. Each section tests a different skill and has a strict time limit. Knowing how long each section will take helps you pace yourself during the test and make travel arrangements to and from the testing center. You'll also be able to pace yourself on practice tests and the real thing to make sure you answer as many questions as possible and get a high score.
Core Sections
There are three core portions of the ACT. These subjects make up the main score that colleges see on your application. They are: English, Math, and Reading.
ACT English Section
minutes
Focus
Grammar, punctuation, sentence structure, rhetorical skills
The English section of the ACT includes multiple-choice questions about short text passages. Being able to read and comprehend quickly, edit swiftly and accurately, and mark your answers correctly are key skills. Since there are far more prompts than there are minutes, students only have about 30 seconds to answer each question, since those 30 seconds don’t include the duration spent reading.
ACT Math Section
minutes
Focus
Algebra, geometry, trigonometry, basic statistics
Students will be required to examine short prompts and word problems and select the correct multiple-choice answer. High school concepts like rates, percentages, statistics, and proportions, along with higher skills such as algebra and functions, make up the majority of questions. There may be several charts and diagrams. Expect to encounter several multi-step problems.
ACT Reading Section
minutes
Focus
Reading comprehension
This section measures students’ abilities to read closely and use given information to draw logical conclusions. Major skills include identifying main ideas, understanding sequences of events, using context clues, analyzing claims, and integrating information from multiple sources. One passage may include a diagram that includes visual and quantitative elements.
The 3 core sections are each different lengths:
English: 35 minutes
Math: 50 minutes
Reading: 40 minutes
The optional portions are each 40 minutes long.
Optional Sections
The two optional ACT parts can be a wise inclusion for many types of college applications. Deciding whether you should include them in your test requires researching your target school’s admissions process. Some may indicate a requirement or a preference for these optional parts.
ACT Science Section
minutes
Focus
Interpretation, analysis, reasoning, problem-solving
While students don’t need in-depth knowledge in any particular scientific subject, having background knowledge is expected. Knowledge of scientific thinking and the scientific process are typically required in order to discern the correct answers. The section focuses on students’ abilities to interpret given data and draw logical, evidence-based conclusions, or identify flawed reasoning.
ACT Writing Section
minutes
essay
Focus
Analyzing information, integrating information and subjective data, decision-making, writing procedure, grasp of English
The ungraded ACT essay prompt provides information about a complex issue paired with three different perspectives about the issue. Your task is to develop your own perspective or adopt a provided one and defend your stance compared to other perspective(s). Students must be able to parse information quickly, create an idea, make an outline, and execute a well-organized essay with adequate spelling and grammar in the allotted period.
Total Test Duration Including Breaks
The ACT is tightly regulated, but the duration for each student can be different, depending on which optional portions they take (if any). There are 3 different possibilities. Let’s take a look at the ACT time breakdown for online versions of the test:
(185 minutes) From check-in to ending
(235 or 240 minutes) From check-in to ending, depending on the section
(300 minutes) From check-in to ending
Paper test times are a little extended to account for additional setup and transitions between parts. Proctors need to collect and distribute different packets, which adds time in between portions. Students still have the same amount of time to answer questions as those who take the online version of the test. The ACT time breakdown for paper tests is:
ACT with no optional sections: 3h 20m
ACT with science or writing section (respectively): 4h 15m or 4h 30m
ACT with both optional sections: 5h 30m
All the listed timings here include breaks. In both situations, students get a short break (about 15 minutes) between sections 2 and 3. Additionally, students get a 5-minute break between the science and writing portions, if they’re taking both.
In all situations, check-in time is assumed to be 8 AM (that’s the cut-off time for arrival at the testing center). Students all commence the test at the same time, after their proctors have given instructions and students are all set up with their online program or paper tests. So, while the actual pencil-to-paper (or digital equivalent) test time is 125m (~2h) / 165m (2h 45m) / 205m (~3h 25m) respectively, ACT test times include everything from check-in to check-out.
Here's what you can expect your day to look like for the online version of the test:
7:45 - 8 AM
Arrive at the Test Center and Check In
You will not be allowed to enter after 8 AM.
8 to 8:45 AM
Settling In
Students finish up their check-ins, get their materials, and have procedures explained to them by the proctors. You’ll be instructed on how and when to leave the testing room, depending on whether you’re taking any elective sections. Be sure to ask the proctor any inquiries you have before the test begins.
8:45 AM
English Test Starts (35 minutes)
The first of the three required components, English, is the first test of the day.
9:20 AM
Math Test Starts (50 minutes)
There is no break between the English and Math portions.
10:10 AM
Break
You’ll have a 15-minute break to use the restroom, stretch, and have a snack.
10:25 AM
Reading Test Starts (40 minutes)
The final mandatory section.
11:05 AM
Core Test Ends
If you aren’t taking the optional parts, you will finish the core assessment at this time and can leave.
11:15 AM
Optional Science Test Starts OR Optional Writing Test Starts (40 minutes)
There may be a brief break to allow those who are only taking the core sections to pack up and leave without disturbing the remaining students.
If you’re taking only the writing section option, you’ll take it now. If you’re taking both the science and writing portions, you’ll take the science portion first.
11:55 AM
ACT + Science OR Writing Ends
If you only take one elective section, you’ll leave the test center at this time.
Break
A short, 5-minute break at this time allows those who have finished to leave while others prepare for the final optional writing section.
~12:00 PM
Optional Writing Test Starts (40 minutes)
Only those taking the essay portion remain in the testing center.
1:00 PM
All Testing Ends
By this time, all parts of the assessment are complete.
Extended Time Accommodations
Some students qualify for extended testing time on the ACT. Parents/guardians should talk with their student’s school administrative team to discuss whether the student qualifies for extended time and how to apply for it. Accommodation requests must be sent to the ACT at least 10 business days in advance. Sending the application earlier is preferable, in case the request is denied and must be reconsidered. Requests can include accommodations such as:
- 50% extra time for certain sections
- Double time or triple time
- Additional breaks and/or breaks as needed
- Testing over multiple days
- Alternative testing locations
- Use of a screen reader
- Sign language interpreter or written copy of spoken instructions
- Access to food, drink, or medications
- Hearing-assistive technology
- Use of a non-standard calculator
- Service animal
- Wheelchair accessibility
- Fidget devices
- Medical monitoring that requires a cell phone
- Being able to read aloud to self
- Being able to stand up while testing
- Environmental adaptations (background music, special furniture, air conditioning, etc.)
- Personal aide
- Verbal cues to stay on task
- Translations and bilingual dictionaries for English learners
There are even more accommodations possible for the ACT; to see a complete list and procedure, visit the official ACT website and/or meet with your school’s administrative staff. Submitting a request requires providing proof of need, such as an IEP, 504 Plan, or ADA/medical documentation. You will also need to provide a Consent to Release Information to ACT form to your school, who then needs to send it to the ACT. Be sure to read all the ACT rules in advance so you don't accidentally bring a banned item to the testing room!
Time Management Strategies for the ACT
Knowing how long is ACT is only helpful if you can also manage your time on test day. Many students find the ACT difficult mostly because of the strict time limits. Developing and practicing effective time management strategies before test day is vital for completing all the questions on the exam with confidence.
Strategy 1: Understand the Target Pace
Simple math tells you how much time you have per question in each section:
- 40 seconds per question in English
- 1 minute and 6 seconds in math
- 1 minute and 6 seconds in reading
However, you must also remember that you need to review instructions and passages and interpret data multiple times in each section as well, so you don’t have the full 40 seconds or 1 minute and 6 seconds for each question. The only way to get familiar with what the target pace feels like is by completing practice tests.
Strategy 2: Use Practice Tests to Increase Your Pace
Take a timed practice test about 3 months before test day to understand your baseline pace. If you weren’t able to answer all the questions, or barely had time to finish, you know you need to increase your speed.
You can do this by answering more practice questions to get familiar with their structure. Additionally, you will learn to understand how prompts are usually worded and recognize typical giveaways that an answer is incorrect (so you can eliminate it right away). Take at least 2-4 timed practice tests to get used to the process and build endurance.
Strategy 3: Learn to Flag Questions and Make Educated Guesses
Don’t waste time on a question that takes too long. Instead, flag the question and go back later and/or make an educated guess. If you have time at the end of the test, go back and see if you can make a better guess or figure out the answer. Make sure you don’t leave any questions blank, since you don’t lose points for wrong answers.
Strategy 4: Use Passage-Reading Strategies
Practice reading quickly and efficiently, particularly for the reading and English sections. Knowing how to effectively skim and pick out the important details and mark important passages is critical. Learning how to read passages without trying to memorize the whole thing will help you be faster and more effective.
Strategy 5: Memorize Important Equations
The ACT does not provide an equations reference list. You should spend a lot of time memorizing critical math equations in advance, so you can approach the prompts with confidence. Also, make sure you know which equations you will need and which you won't need, so you study effectively.
Strategy 6: Know How to Work With the Answers
Using the answers like tools is a great way to improve your speed. There are several techniques students taking any multiple-choice test can use:
- Read the questions first, then the passage.
- Identify key words in the answers that indicate they are most likely or definitely incorrect (such as “always” or “never”).
- For reading and English, answers must match the tone and style of the text. Eliminate answers that use mismatched formal or casual styles.
- When possible, try inserting the proposed answer into the question to see if it makes sense. (For example, in the English section, read the section with one of the answers inserted in place to see if it flows properly.)
- For math questions, double-check that the formula used is correct. These tests are meticulously crafted, so there are no typos; if something is written wrong, it’s intentional.
- Also for math questions, quickly check outlier answers to see if you can safely eliminate them. Answers that provide non-matching units of measurement can also usually be crossed out.
Strategy 7: Be Aware of the Clock
Check your time after each passage or group of questions to get an idea of your pace. This helps keep you on track and lets you know if you need to speed up or can slow down in the next passage(s). Keep in mind that checking the clock too often can cause more anxiety and takes valuable seconds away. So, get in the habit of only looking at the clock a few times per section.
The ACT can seem intimidating, but if you practice with official questions in advance, your speed and knowledge should be enough to get you through. Overcoming nerves is just as important as skill. Take practice tests to understand what’s expected of you and know what it feels like to take a timed test.
