What is can a calculator be used on the ACT?
When students prepare for their college entrance exams, the most common question asked is: can a calculator be used on the ACT? The answer is a definitive yes, but with strictly enforced limitations. Unlike the SAT, which allows calculators on certain sections and prohibits them on others, the ACT permits calculator use for the entirety of the 60-minute Math section only.
Using the right tool is critical because the ACT test center staff are trained to inspect devices. If you bring a prohibited device, you may be dismissed from the testing center and your scores canceled. Our tool helps you determine if your specific model satisfies the official guidelines so you can focus on solving problems rather than worrying about compliance.
Anyone taking the test—whether a high school junior, senior, or adult learner—should use this checker. A common misconception is that “all graphing calculators are allowed.” This is false. Models with built-in Computer Algebra Systems (CAS) are strictly forbidden.
can a calculator be used on the ACT Formula and Logic
The “formula” for ACT calculator compliance is a logical verification process based on a set of criteria defined by ACT, Inc. The logic follows a “Reject If” protocol. If any of the following conditions are true, the calculator is prohibited.
The mathematical representation of compliance (C) can be expressed as:
C = (NOT CAS) AND (NOT QWERTY) AND (NOT WIRELESS) AND (NOT POWER_CORD)
| Variable | Meaning | Unit | Compliance Range |
|---|---|---|---|
| CAS | Computer Algebra System | Boolean | Must be FALSE |
| QWERTY | Letter Keyboard Layout | Boolean | Must be FALSE |
| COMM | Wireless/Infrared Comm | State | Must be DISABLED |
| NOISE | Audible Alerts | Decibels | Must be 0 (Muted) |
| POWER | External Power Supply | Source | Must be BATTERY/SOLAR |

Practical Examples (Real-World Use Cases)
Example 1: The TI-84 Plus CE
A student brings a Texas Instruments TI-84 Plus CE. This model is a graphing calculator but does not have CAS. It uses a standard numeric keypad with secondary alpha functions. It is battery-operated and silent.
Result: Allowed. This is the most popular choice for the ACT.
Example 2: The TI-Nspire CAS
A student has a TI-Nspire CX II CAS. Despite being a modern, expensive calculator, the inclusion of “CAS” in the name indicates it can solve algebraic equations symbolically.
Result: Prohibited. The student would be required to use a different device or take the test without one.
How to Use This can a calculator be used on the ACT Calculator
- Select Brand: Choose the manufacturer and model series from the dropdown.
- Check CAS: Verify if your calculator has “CAS” printed on the front or in the software menu.
- Inspect Hardware: Look for a full typewriter-style keyboard (QWERTY) or paper tape slots.
- Review Results: The tool will instantly update to show “ALLOWED” or “PROHIBITED.”
- Read the Advice: Follow the specific instructions provided for restricted models (like clearing memory).
Key Factors That Affect can a calculator be used on the ACT Results
- Symbolic Manipulation (CAS): Any device that can factor polynomials or simplify radicals symbolically is banned. This provides an unfair advantage in the math section.
- Communication Features: To prevent cheating, any device with infrared, Bluetooth, or cellular capabilities must have these features disabled or be physically absent.
- Keyboard Layout: Devices with “letter” keys in a standard typing layout are considered communication devices rather than math tools under the ACT calculator policy.
- Power Requirements: You cannot plug your calculator into a wall outlet. Ensure your batteries are fresh or your device is fully charged via solar/internal battery.
- Acoustics: If your calculator beeps or makes noise during the exam, you will be disqualified. Most calculators allow you to mute sounds in the system settings.
- Memory Erasure: While the ACT does not require you to clear your memory, you are prohibited from using stored “programs” that provide unauthorized help or contain test questions.
Frequently Asked Questions (FAQ)
Yes, but only the non-CAS versions. The models labeled “CAS” are strictly prohibited.
Absolutely. Most four-function and scientific calculators are permitted as long as they don’t have prohibited features like paper tape.
No. All mobile phones, tablets, and laptops are strictly prohibited in the testing room.
Yes, the entire TI-84 Plus family (including Silver Edition and CE) is permitted under the can a calculator be used on the ACT guidelines.
Calculators with pens or styluses (like the Casio ClassPad) are generally prohibited because they resemble prohibited electronic devices.
No. Sharing calculators during the ACT is not allowed and will result in dismissal for both parties.
ACT does not require clearing programs, but using them to store test content is a violation of the rules.
Most testing centers do NOT provide calculators. You are responsible for bringing your own approved device.
