ACT Requirements: What Students Need to Know Before Test Day

The ACT does not require a minimum GPA, a particular high school course, or a qualifying practice score. However, students must meet several registration and test-day requirements before they can receive an official score.

Those requirements include registering by the appropriate deadline, submitting an acceptable photo, bringing valid identification, arriving on time, following calculator and electronic-device rules, and obtaining advance approval for any accommodations. Students taking the ACT online with their own device also have technical requirements to complete before test day.

Beyond those formal rules, students need to make several strategic choices. They must decide when to test, whether to take the optional Science or Writing sections, whether paper or online testing suits them better, and how much preparation they need to reach their target score.

Understanding the difference between a true requirement and a strategic recommendation can prevent test-day problems while helping students build a smarter ACT plan.

Are There Academic Requirements to Take the ACT?

There are no academic prerequisites for registering for the national ACT. Students do not need to complete Algebra II, reach a particular GPA, or earn a certain score on the PreACT before signing up.

Most students take the ACT during junior or senior year, after completing much of their core coursework. Students may also take it earlier or after high school when doing so supports their admissions, placement, scholarship, or other goals.

That does not mean every student should test as early as possible. The current ACT measures English, math, reading, and, when selected, science and writing skills. Students who have completed more relevant coursework may be better prepared to demonstrate their knowledge.

Complete ACT Registration Correctly

Students taking the ACT on a national test date generally register through a MyACT account. During registration, they select a test date, testing location, available testing format, and any optional sections they intend to take.

Students should also be prepared to:

Provide accurate personal and high school information
Upload a recent, recognizable photo
Pay the registration fee or use an approved fee waiver
Select a test center with available seating
Review and agree to ACT testing policies

ACT’s official registration page lists upcoming dates, registration deadlines, late-registration periods, and current fees. Registration deadlines are set before the test date, and waiting until the last minute may limit test center or format options.

The student’s registration name should match the name on the identification they plan to present. A nickname, a misspelling, or a significant discrepancy between the registration and the ID can cause problems during check-in.

Students taking the ACT through their school may follow a different registration process. School-day testing is coordinated by the school or district, so students should pay close attention to instructions from their counselor or testing coordinator rather than assuming national registration rules apply in exactly the same way.

Meet the ACT Photo Requirement

A recent photo is required to complete standard ACT registration. The image is used to help testing staff confirm the student’s identity.

The photo should clearly show only the student, facing the camera, against a plain background. It should be a recognizable head-and-shoulders image without filters, stickers, text, dark glasses, or other alterations. ACT accepts several common image formats, but the file must also meet its size and resolution requirements.

Students should not assume that a school portrait, a heavily edited social media photo, or a group picture will be accepted. Upload the image early enough to correct any problem before the deadline.

Once the registration photo and other required information have been accepted, students can access their admission ticket through MyACT.

Bring Acceptable Identification

Valid photo identification is one of the most important ACT test-day requirements.

ACT generally requires an original, current photo ID issued by a school or government agency. The identification must be a physical card rather than a photocopy, a screenshot, a paper reproduction, or an electronic ID. The student’s name should match the registration, and the photo must clearly identify the person presenting it.

A school ID, driver’s license, state identification card, or current passport may meet the requirements if it complies with ACT’s rules.

Students who do not have an acceptable official photo ID may use the ACT Student Identification Form. The form must be completed correctly and validated by an authorized school official or notary. A parent or other relative cannot complete it as a substitute for an official ID.

An admission ticket does not replace photo identification. A birth certificate, Social Security card, yearbook photo, report card, parent’s ID, or personal recognition by a teacher or test-center employee is also insufficient.

Check the identification well before test day. Discovering the night before the exam that a school ID is missing, damaged, expired, or unacceptable leaves very little time to solve the problem.

Print and Review the Admission Ticket

Students should print their ACT admission ticket from MyACT and bring it to the testing center.

The ticket contains registration information and may include test-center messages, match information for a paper answer document, or a launch code for online testing. Students should review the ticket before test day to confirm the location, format, reporting time, and selected test options.

ACT indicates that forgetting the ticket alone may not automatically prevent a student from taking the test. However, missing information can complicate check-in, delay paper score matching, or make logging into the online platform more difficult. Treat the ticket as an essential part of the test-day checklist rather than an optional extra.

Arrive Before the Testing Center Closes

Students should plan to be inside the testing center no later than 8:00 a.m. unless their ticket or school provides different instructions. Late arrivals cannot be admitted after testing procedures have begun.

Do not plan to arrive at exactly 8:00. Allow time for traffic, parking, building security, finding the correct room, and check-in.

A practice trip to an unfamiliar test center can be useful, particularly when the exam is being held at a large high school or college campus. Students should also check MyACT and their email shortly before the test in case the location or testing format has changed.

Know What to Bring to the ACT

Students should prepare their materials the night before the exam. ACT’s official test-day checklist recommends bringing:

An acceptable photo ID
A printed admission ticket
Sharpened No. 2 pencils with erasers
A permitted calculator
A fully charged testing device and charger when registered for bring-your-own-device online testing
A snack or drink for the scheduled break

Students may also bring an acceptable watch or timing device that does not have an alarm, an internet connection, a communication function, or a recording capability. A traditional watch must remain on the desk during testing.

Mechanical pencils, pens, highlighters, notes, books, personal scratch paper, smartwatches, fitness trackers, and unauthorized electronic devices are not permitted.

Follow ACT Calculator Requirements

Calculators are allowed only during the Math section. Students may bring many four-function, scientific, and graphing calculators, but some models and features are prohibited.

Calculators with computer algebra system, or CAS, functionality are generally not permitted. Prohibited examples include TI-89 and TI-92 models, the TI-Nspire CAS, the HP Prime, and certain Casio ClassPad models. Calculators built into phones, tablets, laptops, or other communication devices are also prohibited.

Some otherwise acceptable calculators must be modified before testing. Students may need to remove stored documents or prohibited programs, turn off sound, cover an infrared data port, or remove a paper tape or power cord.

Students may not share calculators during the test. Testing staff do not have to provide a handheld calculator if a student forgets one or brings a prohibited model. Students taking the online ACT do have access to an on-screen Desmos calculator during Math, but they may still use an approved handheld calculator.

Prep Expert®’s ACT Math calculator tips can help students practice using their calculator efficiently. The best test-day calculator is usually one the student has already used during timed practice, not a more advanced model purchased immediately before the exam.

Understand Which ACT Sections Are Required

Under the current national ACT format, English, Math, and Reading are required. Those three sections determine the Composite score.

Science and Writing are optional add-ons for students registering for national testing. Science produces a separate Science score and can also contribute to a STEM score. Writing produces a separate writing score. Neither optional section changes the current English, Math, and Reading Composite score.

Optional does not mean unimportant. A student interested in engineering, health sciences, research, or another STEM field may decide that the optional ACT Science section offers an opportunity to demonstrate relevant reasoning skills.

Before registering, students should check the policies of their intended colleges, scholarships, and academic programs. A college may not require Science or Writing for general admission, but a specific program or scholarship could still consider the additional score.

School-day testing may work differently. A state, district, or school can select a particular test configuration for its administration, so students may not have the same individual choice they would have on a national test date. Ask the school testing coordinator which sections will be administered.

Complete Online Testing Requirements

Students who select online testing should confirm whether the testing center will provide a computer or whether they registered for the bring-your-own-device option.

Bring-your-own-device students must use a supported personal or school-managed computer, install ACT Gateway, and complete the required device-readiness checks before test day. Personal devices must be Windows or Mac laptops. Personal Chromebooks, Windows S Mode devices, iPads, and tablets are not supported.

Do not assume that a testing center will have a backup computer available for a student registered to bring a device. Review all readiness instructions in MyACT and complete the setup process before the final evening.

Students deciding between paper and online testing should consider how they read, annotate, manage time, and maintain concentration on a screen. The academic content is comparable, but the experience may feel different.

Request Accommodations in Advance

Students who need extended time, alternate-format materials, additional breaks, screen-reader access, or other accommodations must request and receive approval before testing.

Most students enrolled in a public, private, or virtual school should work through a counselor, testing coordinator, special education coordinator, or another authorized school official. Homeschooled students and students who are no longer enrolled follow a separate process.

A current IEP or Section 504 plan may provide sufficient documentation for the same allowable accommodations, but the request still needs to be submitted and approved. Students should not assume that accommodations received at school will automatically appear on their ACT registration.

For current national test dates, ACT generally requires accommodation requests by the regular registration deadline. Submitting early leaves time to provide additional documentation or appeal a decision when necessary.

Follow Test Security and Electronic-Device Rules

Cell phones, smartwatches, fitness bands, and other communication or recording devices must remain powered off and out of sight. Students may not access them during testing or scheduled breaks.

A device that rings, activates, or is accessed can result in dismissal and cancellation of the student’s score. Students may also be dismissed for sharing answers, continuing after time is called, working on the wrong section, using unauthorized materials, impersonating another test taker, or disclosing secure test questions.

These rules apply even when a violation seems accidental. Turning a phone to silent is not enough. Power it down completely and store it according to the testing staff’s instructions.

Consider Whether the ACT Is the Right Test

Meeting the ACT requirements does not necessarily mean the ACT is the best admissions exam for every student.

The SAT and ACT are both widely used, but they differ in pacing, passage structure, math coverage, and testing format. Students who have not chosen an exam should compare current practice results and review the differences between the SAT and ACT in 2026.

Take a realistic diagnostic for each exam before committing months of study time. Consider not only the converted scores, but also which test feels more manageable and where improvement appears most attainable.

Choose a Useful ACT Test Date

The best ACT date is not simply the next available Saturday. Students should consider:

College application deadlines
Scholarship score deadlines
Current practice-test performance
Time available for preparation
School exams and major projects
Athletics, performances, work, and family commitments
Whether there will be time for a retake

A first official test during junior year often leaves room to review the results, address weaknesses, and test again. Seniors working near application deadlines should confirm when colleges must receive scores rather than assuming every fall test date will work.

Registering early also improves the likelihood of finding a convenient test center and preferred testing format.

Set a Target Score Before Studying

Students should prepare for a defined target rather than vaguely trying to “do well.”

Research the ACT ranges at intended colleges and any score thresholds used for scholarships. Then take a full-length practice test and compare the baseline with the target.

Prep Expert®’s guide to 2026 ACT score percentiles can help students understand how their current score compares to other test-takers. Percentiles provide context, but the most useful target is one connected to the student’s actual admissions and scholarship goals.

The size and pattern of the score gap should shape the study plan. A student who needs one additional Composite point may benefit from targeted pacing work, while a student seeking a larger increase may benefit from broader content review and more preparation time.

Review the ACT Requirements Before Test Day

Several days before the exam, confirm that every requirement has been addressed:

Registration is complete
The photo has been accepted
The admission ticket is printed
The testing location and format are correct
The student has acceptable identification
Any accommodations have been approved
The calculator is permitted and working
Online device checks are complete, when applicable
No. 2 pencils and other allowed materials are packed
Transportation and arrival time are planned
Phones and prohibited devices will remain off and stored

This final review should happen before the night of the test. Many administrative problems are easy to solve several days in advance and extremely difficult to solve at the testing-center door.

Meet the Requirements, Then Prepare to Perform

ACT requirements determine whether a student can register, enter the testing room, and complete the exam under valid conditions. Preparation determines what happens after the test begins.

Handle registration, identification, calculator rules, device setup, and accommodations early. Then focus on learning the current format, completing realistic practice tests, analyzing missed questions, and improving pacing.
