Introduction
The ACT comes in two formats: a printed paper test and an online (computer) test. Both formats test the same content and skills, given scores mean the same thing on either one, and colleges treat them equally. What differs is the experience of taking it. How you move through questions, mark up a passage, and keep track of your time all feel different on a screen than on paper, and those differences can make one format the better fit for a student.
This is Matter’s parent guide to how the two formats differ and how to pick the best one for your testing experience. For the full orientation, start at our ACT Resource Hub.

What’s the same in both formats
Both formats cover the same sections, test the same skills, and use the same scoring scale, so a 30 on paper is the same as a 30 online. ACT describes the choice merely as a preference: “Digital testing gives you a modern, screen-and-keyboard testing experience while the paper ACT offers a classic format well-known to all”.
The fee is the same, and the required and optional sections are the same. Whether Science and Writing are part of your child’s day depends on what you register for, not on the format (see our guide to the enhanced ACT).
The online ACT: tools, devices, and software
Choosing the computer format means your child takes the ACT on screen at a test center, using either their own device or one the center provides. Beyond that, the biggest practical difference is the built-in tool set that every online tester gets:
Reading and tracking tools: a line-reader tool that mimics a straightedge, and text highlighting
Answering tools: answer masking, an option eliminator, mark-for-review, and an on-screen timer.
Vision supports: on-screen magnification.
Math: an on-screen Desmos calculator, available to every online tester.
*These tools are available to all online students, not just those with accommodations.
If your family registers directly for a national test date, the online ACT runs in an app called ACT Gateway. If your child’s school or district administers the ACT on a school day, it runs in Pearson’s TestNav.
To get comfortable before test day:
National (ACT Gateway): there is no practice version of the Gateway app itself, so use ACT’s browser-based online practice tests and sample questions, which mirror the on-screen interface. Students who bring their own computer will need to install ACT Gateway ahead of time and run a device-readiness check.
State/District (TestNav): familiarize yourself with TestNav’s online practice ACT or walk through ACT’s TestNav tutorial to see the exact interface.
The paper ACT: the classic format
The paper ACT is the printed booklet and bubble answer sheet families have known for decades. Your child can annotate directly on the page, underline text, do math on the booklet margins, label diagrams, cross out answers by hand, and bring an approved handheld calculator for the Math section.
The trade-off is the separate answer sheet. Because answers are bubbled apart from the questions, a student who skips an item or loses their place can slip out of sync and mark an answer in the row for a different question, which quietly throws off every answer after it.
When your scores arrive
Online results generally post about five days before paper results. For example, the April 11, 2026 test date released online scores on April 16 and paper scores on April 21.
In general, ACT reports multiple-choice scores within two to eight weeks of the test date, and Writing scores within five to eight weeks. If a fast turnaround matters for an application deadline, the online format has a small edge.
How to choose
Choose online if your child reads comfortably on a screen, likes the built-in tools (highlighter, answer eliminator, on-screen Desmos calculator), and wants scores a few days sooner. Note that all scratch work goes on separate scratch paper, so it can get disorganized unless your child is deliberate about labeling which problem each calculation belongs to.
Choose paper if your child annotates heavily by hand, works math in the margins, or finds screens tiring over a multi-hour test. Keeping the work right next to the problem also makes it easier to stay organized, especially when labeling diagrams or checking a calculation against the question.
Test-center availability can decide it for you. Not every center offers every format on every date, so check what is available when you register.
Pro tip: practice in the format your child will test in. Familiarity with the interface or the booklet on test day matters more than the format itself.
Common questions about the ACT format
Is the test harder on paper or online? Neither. Content-wise, the tests are the exact same. ACT tests the same content and skills in both, and scores are comparable across formats.
Does my child need to bring a laptop for the online ACT? No. Online testers can bring their own device (BYOD) or use a device the test center provides. You make this choice when you register for your test in MyACT and you can change it up until the late registration deadline for your test date (for a fee, if a seat is available).
Can they use a calculator on the test? Yes. An approved handheld calculator is allowed on Math in both online and paper formats; online testers also have an on-screen Desmos calculator.
Do colleges care which format we choose? No. Both are accepted equally at accredited US colleges.
