Check Your Calculator’s Status

Enter Your Calculator Model

Enter the full model name as written on your calculator.

Check for Prohibited Features

Does it have a Computer Algebra System (CAS)?

(Usually indicated by “CAS” in the model name, e.g., TI-Nspire CAS)

Does it have a QWERTY (typewriter-style) keyboard?

Does it need to be plugged into an electrical outlet to work?

Can it communicate wirelessly (e.g., Wi-Fi, Bluetooth)?

Is it part of a cell phone, tablet, or laptop?

Check for Features Requiring Modification

Does it use paper tape?

Does it make noise?

Does it have an infrared data port?

What is the ACT Calculator Policy?

The ACT has a specific policy regarding which calculators can be used during the math portion of the test. While every math problem on the ACT can be solved without a calculator, using an approved one can significantly help with speed and accuracy. The core principle is to ensure fairness and prevent any student from having an unfair advantage through technology. Therefore, the question “can we use the calculator at the ACT” is best answered with: yes, provided it’s an approved model without prohibited features.

Students can generally use any four-function, scientific, or graphing calculator, as long as it’s not on the prohibited list and is modified if necessary. Prohibited devices include those with advanced features like a Computer Algebra System (CAS), wireless communication, or a QWERTY keyboard.

ACT Calculator Policy Formula and Explanation

The “formula” for determining if a calculator is allowed isn’t mathematical but a series of logical checks. Our calculator automates this process. Here’s how it works:

Check for Prohibited Devices: Devices like cell phones, tablets, or laptops are never allowed as calculators.
Check for Banned Features: The device is checked for explicitly banned features, such as a Computer Algebra System (CAS) or a QWERTY keyboard.
Check Against Prohibited Model List: The model name is compared against a known list of banned calculators.
Check for Modifications: The calculator checks for features that are allowed only if modified (e.g., removing paper tape).

Prohibited vs. Permitted Models

This table highlights examples of common calculators and their status according to the ACT calculator policy.
Variable (Calculator Model)	Status	Reasoning / Unit of Measure
TI-84 Plus CE	Permitted	Standard graphing calculator, no CAS. Widely used and approved.
TI-Nspire (non-CAS)	Permitted	The non-CAS version is explicitly allowed.
TI-89	Prohibited	Contains a built-in Computer Algebra System (CAS).
TI-92	Prohibited	Contains both a CAS and a QWERTY keyboard.
HP Prime	Prohibited	Contains a built-in Computer Algebra System (CAS).
Casio fx-9750GII	Permitted	A popular graphing calculator without CAS functionality.
Any calculator on a phone	Prohibited	Cell phones and other communication devices are strictly banned.

Practical Examples of Using the ACT Calculator Policy

Example 1: A Permitted Calculator

Input Model: TI-84 Plus
Input Features: None of the prohibited or modification-required features are selected.
Result: PERMITTED. The TI-84 Plus is one of the most common and widely accepted calculators for the ACT.

Example 2: A Prohibited Calculator

Input Model: TI-89 Titanium
Input Features: The user checks the box for “Does it have a Computer Algebra System (CAS)?”.
Result: PROHIBITED. All calculators with CAS functionality, like the TI-89 series, are banned from the ACT.

How to Use This ACT Calculator Policy Checker

Enter Your Calculator’s Model: Type the model name exactly as it appears on your device into the input field.
Identify Prohibited Features: Review the list of prohibited features. If your calculator has any of these (like a QWERTY keyboard or CAS), check the corresponding box.
Identify Modification Needs: If your calculator makes noise or has paper tape, check the appropriate box. These don’t automatically ban the calculator but require action.
Click “Check My Calculator”: The tool will instantly analyze your inputs based on the official ACT calculator policy.
Review Your Result: The output will clearly state if your calculator is Permitted, Prohibited, or Permitted with Modifications.

Checking your device is an important part of your test day prep.

Key Factors That Affect ACT Calculator Permission

Computer Algebra System (CAS): This is the most common reason for a calculator to be banned. CAS can perform algebraic manipulations, which is not allowed.
QWERTY Keypad: Calculators with a typewriter-style keyboard are prohibited.
Communication Capabilities: Any device that can connect to the internet or other devices wirelessly is banned.
Power Source: Calculators needing an external power source are not permitted.
Noise and Paper: Calculators that make noise must be muted, and those with paper tape must have the tape removed.
Device Type: The calculator function cannot be on a phone, tablet, or computer.

Understanding these factors is key to knowing what calculators are allowed on the ACT.

Frequently Asked Questions (FAQ)

1. Can you use a TI-84 Plus on the ACT?

Yes, the TI-84 Plus (including the CE version) is one of the most popular and fully approved calculators for the ACT.

2. Are graphing calculators allowed on the ACT?

Yes, most graphing calculators are permitted as long as they do not have prohibited features like a Computer Algebra System (CAS). Models like the TI-84 series are fine, but models like the TI-89 are not.

3. What happens if I bring a banned calculator?

You will not be allowed to use it. Test centers do not provide backup calculators, so you would have to take the math test without one.

4. Can I use the calculator on my phone?

No, using a calculator on a cell phone, tablet, or any other communication device is strictly prohibited.

5. What does “Permitted with Modifications” mean?

This means your calculator is allowed, but you must make a change. For example, you must remove the paper tape from a printing calculator or mute a calculator that makes noise.

6. Is the TI-Nspire allowed on the ACT?

It depends. The standard TI-Nspire (non-CAS) is permitted. However, the TI-Nspire CAS is explicitly prohibited.

7. Do I need a calculator for the ACT?

No, all math problems can be solved without a calculator. However, a permitted calculator is highly recommended to save time and reduce calculation errors.

8. Can I share my calculator with a friend during the test?

No, sharing calculators during the test is not allowed under any circumstances. If you’re looking for more guidance, check out our ACT Math Strategies guide.
