ACT Accepted Calculators & Policy Checker
An essential tool for any student preparing for the ACT math test.
ACT Calculator Status Checker
Enter your calculator’s model number (e.g., “TI-84 Plus CE” or “Casio fx-9750GII”) to instantly see if it’s one of the act accepted calculators for test day.
What is the ACT Calculator Policy?
The ACT calculator policy outlines the rules regarding which calculators are permitted for use on the math section of the ACT test. This policy is designed to ensure fairness for all test-takers by preventing access to devices with features that could provide an unfair advantage, such as computer algebra systems (CAS) or wireless communication. Understanding the list of act accepted calculators is crucial for a smooth test day experience.
Anyone taking the ACT math test should be familiar with this policy. While all math problems on the ACT can be solved without a calculator, using a familiar and permitted device can save valuable time and help with accuracy. A common misconception is that you need the most expensive graphing calculator; in reality, the best calculator is one you are comfortable and proficient with that meets the ACT’s criteria.
ACT Calculator Rules and Prohibited Features
Instead of a mathematical formula, the ACT policy is a set of rules defining prohibited features. Your calculator is generally fine if it’s a standard graphing or scientific calculator. However, if it has any of the features listed below, it is NOT one of the act accepted calculators. The core principle is preventing devices that can solve algebraic equations symbolically or communicate with other devices.
Here’s a breakdown of the “variables” that determine if a calculator is banned:
| Feature (Variable) | Meaning | Reason for Prohibition | Typical Range/Example |
|---|---|---|---|
| Computer Algebra System (CAS) | The ability to manipulate and solve algebraic expressions symbolically. | This automates algebra, which the test is designed to measure. | TI-89, TI-Nspire CAS, HP Prime |
| QWERTY Keyboard | A letter-key layout like a computer keyboard. | Prevents devices that are essentially small computers. | Some older models or specialty devices. |
| Wireless Communication | Features like Wi-Fi, Bluetooth, or infrared ports. | Prevents communication and cheating. | Phones, tablets, smartwatches. |
| Pen-Input / Stylus | Electronic writing pads or devices that use a stylus for input. | These are considered computer-like devices. | Sharp EL 9600 is a noted exception and IS allowed. |
| External Power | Calculators that need to be plugged into an electrical outlet. | Logistical and safety issues in the testing room. | Any calculator with a power cord. |
Practical Examples of ACT Accepted Calculators
Example 1: The Prohibited Calculator
A student owns a TI-Nspire CX II-T CAS. They enter “TI-Nspire CX II-T CAS” into the checker.
- Input: TI-Nspire CX II-T CAS
- Output Status: PROHIBITED
- Interpretation: The result is prohibited because the “CAS” in the name stands for Computer Algebra System. The policy explicitly forbids any calculators with CAS functionality. The student must find a different, non-CAS calculator for the test, such as a TI-84 Plus or a non-CAS TI-Nspire.
Example 2: The Permitted Calculator
Another student has a TI-84 Plus, a very common choice. They enter the model name into the checker.
- Input: TI-84 Plus
- Output Status: ALLOWED
- Interpretation: This model is one of the most popular act accepted calculators. It is a powerful graphing calculator without a CAS. The student should ensure the calculator’s memory is cleared of any notes or programs before test day, as required by the policy for devices that can store information.

How to Use This ACT Accepted Calculators Checker
Using this tool is straightforward and can prevent a major headache on test day. Follow these simple steps to verify your device.
| Step | Action | Details |
|---|---|---|
| 1 | Find Your Model Number | Look at the top of your calculator. The model number is usually printed clearly (e.g., “fx-9750GII”, “TI-30XS”). |
| 2 | Enter the Model | Type the model number into the “Calculator Model” input field above. The check happens in real-time. |
| 3 | Review the Result | The box below will instantly update to show “ALLOWED”, “PROHIBITED”, or “ALLOWED (with modifications)”. |
| 4 | Read the Details | The intermediate results will explain *why* your calculator has that status, citing the specific rule from the ACT calculator policy. If you are uncertain about the rules, check out our guide on {related_keywords}. |
Key Factors That Affect Your Calculator Choice
Choosing from the list of act accepted calculators involves more than just picking a permitted model. Several factors can influence your performance.
Frequently Asked Questions (FAQ)
No. All phones, smartwatches, and any device capable of external communication are strictly prohibited. Using one will result in your dismissal from the test.
CAS stands for Computer Algebra System. It lets a calculator solve `x + 3 = 5` for `x` symbolically, rather than just crunching numbers. The ACT is designed to test *your* algebra skills, so CAS is banned.
It depends. The standard TI-Nspire and TI-Nspire CX (non-CAS) models are allowed. However, the TI-Nspire CAS and TI-Nspire CX CAS models are strictly prohibited. Check the calculator’s faceplate carefully!
The testing staff will not allow you to use it. You will have to take the math test without a calculator. They will not provide a replacement, so checking the list of act accepted calculators beforehand is essential.
Yes. For calculators that can store programs or documents (like the TI-84 Plus family), you are required to clear the memory of any such items before the test begins.
Generally, yes. Standard scientific calculators (like the TI-30 series) do not have prohibited features and are among the safest choices. They are a core part of the list of act accepted calculators. To see a comparison, read about {related_keywords}.
Not necessarily. A graphing calculator can be useful for visualizing problems, but if you aren’t proficient with its graphing functions, it can be slower. Many students score very high using only a scientific calculator. The best choice depends on your personal comfort and strategy.
Some older models, like the HP 38G series, have infrared ports. According to the ACT calculator policy, you must completely cover the port with opaque tape (like electrical or duct tape) for the calculator to be permitted.
