Can You Use a Calculator on the ACT? Policy Checker
Check if your calculator is likely allowed on the ACT Math section based on its features and the official policy.
ACT Calculator Policy Checker
Calculators are only permitted on the Math section of the ACT.
CAS can symbolically solve equations (e.g., find ‘x’ in 2x+3=7).
Some specific models with stylus are allowed ONLY if they are placed in test mode and meet other criteria.
These models (and others like them) are explicitly prohibited due to CAS or other features.
The TI-Nspire (non-CAS) is allowed only if the OS is updated and it’s in test mode (blinking light).

Understanding the ACT Calculator Policy
The ACT® test has specific rules about which calculators are permitted and which are prohibited during the Math section. It’s crucial to understand these rules before your test day to avoid any issues. You are NOT allowed to use a calculator on any other section of the ACT (English, Reading, Science, Writing).
Permitted vs. Prohibited Calculator Features on ACT Math
Here’s a summary of features that generally determine if you can use a calculator on the ACT Math section:
| Feature/Type | Status on ACT Math | Notes |
|---|---|---|
| Basic 4-function | Permitted | Allowed. |
| Scientific | Permitted | Most are allowed. |
| Graphing (non-CAS) | Permitted | Most are allowed (e.g., TI-83, TI-84 series). TI-Nspire (non-CAS) requires test mode. |
| CAS (Computer Algebra System) | Prohibited | Calculators with CAS are not allowed (e.g., TI-89, TI-92, TI-Nspire CAS). |
| QWERTY Keyboard | Prohibited | Calculators with typewriter-like keyboards are not allowed. |
| Stylus or Pen Input | Generally Prohibited | Some exceptions exist for specific models placed in test mode, check ACT policy. |
| Wireless/Bluetooth/Cellular | Prohibited | No communication capabilities allowed. |
| Needs Electrical Outlet | Prohibited | Must be battery-operated. |
| Part of Phone/Tablet/Laptop | Prohibited | No smart devices. |
| Makes Noise / Has Paper Tape | Prohibited | Must be silent and without tape. |
| TI-89, TI-92, TI-Nspire CAS | Prohibited | Explicitly banned due to CAS or other features. |
| TI-Nspire (non-CAS) | Permitted with Conditions | Allowed ONLY if OS is updated and it’s in test mode (blinking light). |

What is the ACT Calculator Policy?
The ACT calculator policy outlines the rules regarding the use of calculators during the ACT test. Specifically, it details whether you can use a calculator on the ACT, which sections permit them (only Math), and what types and models of calculators are allowed or prohibited. The primary goal is to ensure fairness and prevent any student from having an unfair advantage through calculator capabilities like Computer Algebra Systems (CAS) or communication features.
Students taking the ACT Math test should carefully review the latest official policy on the ACT website before test day. Misunderstanding these rules could lead to your calculator being confiscated or even dismissal from the test.
Common misconceptions include believing all graphing calculators are banned (most non-CAS ones are allowed) or that calculators are allowed on the Science section (they are not).
ACT Calculator Policy: Key Rules
The decision on whether you can use a calculator on the ACT Math section hinges on several key rules:
- Permitted on Math Only: Calculators are only allowed during the 60-minute Math test.
- Prohibited Features: Calculators with features like CAS (which can solve equations algebraically), QWERTY keyboards, wireless communication, stylus/pen input (with exceptions), noise, or paper tape are generally banned.
- Prohibited Devices: You cannot use the calculator function on a phone, tablet, laptop, or any other smart device.
- Specific Models: Some models are explicitly prohibited (e.g., Texas Instruments TI-89, TI-92, TI-Nspire CAS). Some, like the TI-Nspire (non-CAS), are allowed only under specific conditions (updated OS, test mode activated).
- Your Responsibility: It’s your responsibility to know if your calculator is permitted. Test center staff may not be familiar with every model.
Always check the official ACT calculator policy document for the most up-to-date and detailed information.
Practical Examples (Real-World Use Cases)
Let’s look at whether you can use a calculator on the ACT in these scenarios:
Example 1: Using a TI-84 Plus CE
- Calculator: Texas Instruments TI-84 Plus CE
- Features: Graphing, no CAS, no QWERTY, no wireless.
- Policy Check: The TI-84 Plus CE is generally allowed as it does not have CAS or other prohibited features.
- Result: Likely PERMITTED.
Example 2: Using a TI-Nspire CX CAS
- Calculator: Texas Instruments TI-Nspire CX CAS
- Features: Graphing, has CAS, no QWERTY, no wireless.
- Policy Check: The “CAS” in the name indicates it has a Computer Algebra System, which is prohibited.
- Result: PROHIBITED.
Example 3: Using a TI-Nspire CX (non-CAS)
- Calculator: Texas Instruments TI-Nspire CX (non-CAS version)
- Features: Graphing, NO CAS, no QWERTY, no wireless.
- Policy Check: The non-CAS version is permitted BUT requires the latest OS and must be placed in “Test Mode” (blinking light visible to proctor).
- Result: PERMITTED WITH CONDITIONS (Test Mode required).
How to Use This Calculator Policy Checker
- Select Features: Go through each question in the “ACT Calculator Policy Checker” above and select “Yes” or “No” (or the appropriate option) based on your calculator’s features.
- Check Result: The “Primary Result” box will update to show “Likely PERMITTED,” “Likely PROHIBITED,” or “PERMITTED with Conditions.”
- Review Reasons: The “Reasons / Key Factors” list will explain why the result was reached based on your selections.
- Official Check: This tool provides guidance, but you MUST always verify with the official ACT calculator policy on the ACT website.
If the checker indicates “Likely PROHIBITED,” do not bring that calculator to the test. If it says “PERMITTED with Conditions,” make sure you fulfill those conditions (like test mode for TI-Nspire non-CAS) before test day.
Key Factors That Affect Whether You Can Use a Calculator on the ACT
- CAS Capability: The presence of a Computer Algebra System is a primary disqualifier.
- QWERTY Keyboard: Calculators with typewriter-like keyboards are not allowed.
- Communication Features: Any form of wireless communication (WiFi, Bluetooth) is prohibited.
- Power Source: Calculators needing an external power source are not allowed.
- Integrated Devices: Calculators built into phones, tablets, or laptops are forbidden.
- Specific Model Bans: The ACT explicitly lists certain models (like TI-89, TI-92, TI-Nspire CAS) as prohibited.
- Test Mode Requirements: Some advanced calculators (like TI-Nspire non-CAS) are only allowed if placed in a specific test mode with the latest OS.
- Noise/Tape: Calculators that make noise or have a paper tape are not permitted.
Frequently Asked Questions (FAQ)
No, you absolutely cannot use your phone, tablet, smartwatch, or any other smart device as a calculator on the ACT. Phones must be turned off and put away.
No, most graphing calculators that do NOT have CAS are allowed. Popular models like the TI-83, TI-84 series, and TI-Nspire (non-CAS in test mode) are generally permitted.
CAS (Computer Algebra System) allows a calculator to perform symbolic algebra (e.g., solve for x, factor polynomials). The ACT bans CAS to ensure students are tested on their mathematical reasoning and problem-solving skills, not just the calculator’s power.
No, calculators are NOT permitted on the ACT Science section. They are only allowed on the Math section.
If you are found with a prohibited calculator, it will likely be confiscated, and you may be dismissed from the test, and your scores could be canceled.
The CAS version will usually have “CAS” printed on the calculator face or in its model name. If you’re unsure, check the manufacturer’s specifications. The TI-Nspire CX II-T is non-CAS, while the TI-Nspire CX II-T CAS has CAS.
If your calculator has any feature listed as prohibited (like QWERTY or wireless), it’s not allowed, even if the model isn’t explicitly listed. When in doubt, bring a simpler, clearly permitted calculator or check directly with ACT.
Always check the official ACT website (act.org) for the most current calculator policy document. It’s usually updated periodically. You can also explore our ACT Math Prep resources.
