A summary of key features and whether they are allowed on the ACT. Following this guide is crucial to the question: do you get a calculator on the act.

What is the ACT Calculator Policy?

A common question students ask is, “do you get a calculator on the act?”. The answer is yes, but with very specific rules. The ACT Calculator Policy is a set of guidelines established by ACT, Inc. to ensure fairness and test security for all students taking the exam. While you are permitted to use a calculator on the Mathematics section of the ACT, not all calculators are allowed. The policy defines which types of calculators are permitted, which are expressly prohibited, and which require modification. Understanding these rules is crucial, as being found with a non-compliant device can lead to dismissal from the test center and cancellation of your scores.

The core purpose of this policy is to prevent any student from having an unfair advantage. Prohibited features, such as Computer Algebra Systems (CAS) or internet connectivity, could allow a student to solve problems beyond their actual mathematical skill level. The policy ensures that the calculator serves as a tool for computation, not as a replacement for understanding mathematical concepts. Therefore, when you ask “do you get a calculator on the act,” the answer is conditional on following these important rules.

ACT Calculator Rules and Logical Explanation

Instead of a mathematical formula, the ACT calculator policy is a logical “formula” based on a series of checks. Your calculator’s eligibility is determined by its features. Here’s a step-by-step breakdown of the logic this calculator uses to answer if do you get a calculator on the act for your specific device.

Device Type Check: Is the device a standalone calculator? Devices like phones, tablets, or laptops are immediately disqualified.
Prohibited List Check: Does the model name appear on the official list of banned calculators? This includes models like the TI-89, HP Prime, and Casio ClassPad series.
Feature Check (CAS): Does the calculator have a Computer Algebra System (CAS)? This is an automatic disqualification.
Feature Check (Keyboard): Does it have a QWERTY keyboard? This is also an automatic disqualification.
Modification Check: Does it have features like a paper tape, noise, or an infrared port? These are only allowed if modified (tape removed, sound muted, port covered).

Logical Variables for ACT Calculator Eligibility
Variable (Feature)	Meaning	Permitted Value	Typical Range
Is Standalone	The device is a dedicated calculator.	Yes	Yes / No
Has CAS	Has a Computer Algebra System.	No	Yes / No
Has QWERTY	Has a typewriter-style keyboard.	No	Yes / No
On Prohibited List	Model is explicitly banned by name.	No	Yes / No
Needs Modification	Features like sound or paper tape.	Yes (if modified)	Yes / No

Practical Examples (Real-World Use Cases)

Example 1: The Compliant Student

Scenario: Maria has a Texas Instruments TI-84 Plus CE, one of the most common graphing calculators. She uses our checker to be sure.

Model Name Input: TI-84 Plus CE
Has CAS?: No
Has QWERTY?: No
Is it a phone/tablet?: No

Result: ALLOWED. The calculator explains that the TI-84 Plus series is permitted, it does not have CAS, and it meets all other criteria. Maria can confidently bring her calculator to the test. This is a clear “yes” to “do you get a calculator on the act.”

Example 2: The Prohibited Calculator

Scenario: David has a Texas Instruments TI-89 Titanium, a powerful calculator he uses for his advanced high school math class.

Model Name Input: TI-89 Titanium
Has CAS?: Yes
Has QWERTY?: No
Is it a phone/tablet?: No

Result: PROHIBITED. The checker flags the TI-89 model by name as being on the prohibited list. It also identifies that the reason is its built-in Computer Algebra System (CAS). David now knows he needs to find an alternative calculator, like a TI-83 or TI-84, for test day.

Key Factors That Affect ACT Calculator Eligibility

Several key factors determine whether you can use your calculator. Understanding these is vital to correctly answering “do you get a calculator on the act” for your device.

Computer Algebra System (CAS): This is the most significant factor. Any calculator with CAS functionality is strictly prohibited because it can perform symbolic algebra, which goes against the test’s purpose of assessing your skills.
QWERTY Keyboards: Calculators with a typewriter-style keyboard are banned to prevent the storage of notes or formulas.
Communication Capabilities: Any device that can communicate wirelessly (Bluetooth, Wi-Fi, infrared) or connect to the internet is forbidden. This is why phones and smartwatches are not allowed.
Explicitly Prohibited Models: The ACT provides a specific list of banned models, including the TI-89, TI-92, HP Prime, and others. Always check your model against this list. Learn more by comparing the ACT vs SAT calculator rules.
Power Source: Calculators needing an electrical outlet are not permitted. Your calculator must be battery-operated.
Physical Modifications: Some calculators are only allowed if you modify them. This includes removing paper tape from printing calculators or covering an infrared port with opaque tape.

Frequently Asked Questions (FAQ)

1. Can I use a TI-84 Plus on the ACT?: Yes, the TI-84 Plus, including the TI-84 Plus CE, is one of the most popular and widely accepted graphing calculators for the ACT.
2. Is the TI-Nspire allowed on the ACT?: It depends. The TI-Nspire (non-CAS) model is permitted, but the TI-Nspire CAS model is strictly prohibited. You must ensure you have the non-CAS version.
3. Do I have to clear the memory on my calculator?: The ACT requires that you remove any programs or documents that have Computer Algebra System functionality. Proctors may inspect your calculator, so it’s best practice to clear any non-essential programs or data before the test.
4. What happens if I bring a prohibited calculator?: If you are found with a prohibited calculator during the test, you will likely be dismissed, and your score will be voided. It is your responsibility to bring a compliant device.
5. Does the ACT provide calculators?: No, test officials will not supply calculators. You must bring your own, and it is recommended to bring a backup calculator or extra batteries just in case. It’s a good idea to check ACT test dates well in advance to prepare.
6. Can I use my phone’s calculator app?: Absolutely not. The use of cell phones, tablets, or any other communication device is strictly forbidden during the entire test session.
7. Are calculators allowed on the ACT Science section?: No, calculators are only permitted for the Mathematics test. They are not allowed on the Reading, English, or Science sections.
8. How do I know if my calculator has CAS?: CAS functionality is usually a major selling point. Check the calculator’s manual, packaging, or the manufacturer’s website. If it can solve equations for variables (e.g., solve(3x+5=11,x)), it has CAS. If you’re still unsure, consulting our free ACT practice tests can help.
