What is the ACT Calculator Policy?
The ACT calculator policy is a set of rules established by ACT, Inc. to ensure fairness and test security during the mathematics portion of the ACT test. While test-takers are encouraged to use a calculator, not all devices are permitted. The policy explicitly defines what calculators can you use for the ACT by outlining prohibited features and listing specific banned models. The primary goal is to prevent any student from having an unfair advantage through devices with advanced functionalities like solving algebraic equations automatically (CAS), storing text, or communicating wirelessly.
This policy is for any student planning to take the ACT. Understanding these rules is crucial because arriving on test day with a prohibited calculator can lead to disqualification. A common misconception is that all graphing calculators are allowed; however, many advanced models, especially those with a Computer Algebra System (CAS), are strictly forbidden. Adhering to the ACT calculator policy is a key part of test preparation.
Prohibited Features and Functionality
Instead of a mathematical formula, the ACT calculator policy is based on a “formula” of prohibited features. The rules are designed to exclude any calculator that can perform tasks beyond the scope of what is being tested. Understanding what calculators can you use for the ACT involves checking your device against this list of banned functionalities.
The step-by-step logic is simple: if a calculator has any of the features listed below, it is not allowed. This framework ensures a level playing field for all students.
| Prohibited Feature | Meaning | Reason for Prohibition |
|---|---|---|
| Computer Algebra System (CAS) | The ability to solve algebraic expressions, simplify equations, and perform symbolic manipulation (e.g., factor, expand). | Directly undermines the math skills the ACT is designed to assess. |
| QWERTY Keyboard | A keyboard with keys arranged like a computer keyboard. | These devices often have text-storage capabilities, posing a security risk. |
| Wireless or Internet Access | Any feature allowing communication with other devices or the internet (Bluetooth, Wi-Fi, infrared). | Prevents cheating and unauthorized access to external information. |
| Needs an Electrical Outlet | Calculators that cannot operate on batteries alone. | Ensures functionality and fairness in all testing environments. |
| Pen-Input or Stylus | Devices that use a stylus for input (with some exceptions like the Sharp EL-9600). | These are often more like small computers (PDAs) with prohibited functionalities. |
| Phone, Tablet, or Laptop | Any device that is not a dedicated, handheld calculator. | These devices have broad communication and data storage capabilities. |

Practical Examples of the ACT Calculator Policy
Applying the ACT calculator policy can be confusing. Here are two real-world examples to clarify what calculators can you use for the ACT.
Example 1: A Prohibited Calculator
- Student’s Calculator: Texas Instruments TI-Nspire CX II-T CAS
- Analysis: The key prohibited feature is “CAS” (Computer Algebra System) in the model name. The ACT explicitly bans all calculators with CAS functionality because they can perform symbolic algebra, which gives an unfair advantage.
- Outcome: This calculator is PROHIBITED. The student must find an alternative, such as the non-CAS version (TI-Nspire CX).
Example 2: A Permitted Calculator
- Student’s Calculator: Texas Instruments TI-84 Plus CE
- Analysis: This graphing calculator does not have a CAS, a QWERTY keyboard, or any wireless capabilities. It is one of the most common and recommended calculators for the ACT.
- Outcome: This calculator is PERMITTED. The student should ensure any non-essential programs are removed from the device’s memory before the test. For more information, you might want to look into an {related_keywords}.
How to Use This ACT Calculator Policy Checker
This tool simplifies checking your device against the official ACT calculator policy. Follow these steps:
- Enter Your Model: Type the full model name of your calculator into the input field above. For instance, “TI-84 Plus” or “Casio fx-115ES Plus”.
- Check the Result: The tool will instantly display one of three statuses:
- PERMITTED: Your calculator is allowed.
- PROHIBITED: Your calculator is on the banned list and cannot be used.
- CHECK MANUALLY / WITH MODIFICATION: Your calculator might be allowed if you make specific modifications (like covering an infrared port) or if it has user-added programs that must be removed. Always refer to the official ACT website in these cases.
- Read the Explanation: The results area provides a brief explanation for the status, helping you understand the specific rule from the ACT calculator policy that applies to your device. Understanding this is as important as knowing your {related_keywords}.
Key Factors That Affect ACT Calculator Legality
Several critical factors determine whether a calculator is compliant with the ACT calculator policy. Being aware of these will help you choose the right tool for test day.
- Computer Algebra System (CAS): This is the most common reason for a calculator to be banned. If “CAS” is in the model name, it’s prohibited. Models like the TI-89 and HP Prime are banned for this reason.
- QWERTY Keyboard: Calculators with a typewriter-style keyboard are not allowed. This is a key differentiator in the ACT calculator policy.
- Communication Capabilities: Any device that can communicate wirelessly (infrared, Bluetooth, Wi-Fi) is forbidden. Some older HP models with infrared ports are only allowed if the port is completely covered with opaque tape.
- Power Source: The calculator must be battery-powered. Devices that require an external power source are not permitted in the testing room.
- Stored Programs/Data: While many graphing calculators can store programs, the ACT requires that you remove any programs with CAS functionality. It is best practice to clear your calculator’s memory of all user-created programs and documents before the test. This is a crucial step when preparing your {related_keywords} for the exam.
- Device Type: The device must be a dedicated handheld calculator. Using the calculator function on a phone, tablet, or smartwatch is strictly prohibited. This is a fundamental rule of what calculators can you use for the ACT.
Frequently Asked Questions (FAQ)
1. Can I use my phone’s calculator on the ACT?
No. Cell phones, smartphones, tablets, and any other communication devices are strictly prohibited from use during the test. Your device must be a standalone, handheld calculator. This is a core tenet of the ACT calculator policy.
2. What’s the difference between the TI-Nspire CX and the TI-Nspire CX CAS?
The TI-Nspire CX (non-CAS) is permitted on the ACT. The TI-Nspire CX CAS is prohibited. The “CAS” stands for Computer Algebra System, which is a banned feature. Always check for “CAS” in the model name.
3. Do I have to clear the memory on my TI-84 Plus?
Yes, it is highly recommended. The ACT policy forbids programs and applications that have CAS functionality. To be safe, you should clear your calculator’s RAM and archive memory of any stored programs or notes before test day.
4. What happens if I bring a prohibited calculator to the test?
If a test proctor finds you are using a prohibited calculator, you may be dismissed from the test, and your score will be voided. It is your responsibility to know and follow the ACT calculator policy.
5. Are all scientific calculators allowed?
Generally, yes. All standard scientific calculators (like the TI-30X series) are permitted as they do not have the advanced features prohibited by the ACT calculator policy. You can find more details in our {related_keywords} guide.
6. Is a graphing calculator necessary for the ACT?
No. According to the ACT, every math problem can be solved without a calculator. However, a permitted graphing calculator (like a TI-84 Plus) can be a powerful tool for solving problems more quickly and verifying answers, making it a valuable part of your {related_keywords} strategy.
7. Where can I find the official, most up-to-date ACT calculator policy?
The definitive source for what calculators can you use for the ACT is the official ACT website. You should always check their policy page for any last-minute changes before your test date.
8. What if my calculator makes noise?
Calculators that make noise are only permitted if the sound feature is turned off. You must mute your device before the test begins to avoid distracting other test-takers.
