ACT Accepted Calculators Checker
An essential tool for students to instantly verify if their calculator is permitted on the ACT test. Avoid test-day surprises by checking your model against the official ACT calculator policy.
Enter the full model name as accurately as possible.
What are ACT Accepted Calculators?
The term “ACT accepted calculators” refers to the range of calculators that are permitted for use during the mathematics portion of the ACT test. To ensure fairness and test security, the ACT has a detailed policy that specifies which calculators are allowed, which are strictly prohibited, and which require modification. While most 4-function, scientific, and graphing calculators are acceptable, certain models with advanced features like a Computer Algebra System (CAS) are banned.
This policy is crucial for every student taking the test. Using a prohibited device can lead to dismissal from the testing room and the voiding of your score. Therefore, it’s vital to check if your calculator complies with the official ACT calculator policy before test day. Our checker is designed to help you quickly understand your calculator’s status.
The “Formula”: How Calculator Status is Determined
There isn’t a mathematical formula for checking a calculator, but rather a set of rules based on features and specific model numbers. The ACT’s primary goal is to ban devices that could provide an unfair advantage, such as those that can solve algebraic equations symbolically or connect to the internet. Our ACT accepted calculators checker uses this logic to determine a model’s status.
The main rules are based on prohibiting specific features and models. Here is a summary of the key factors that lead to a calculator being prohibited:
| Feature/Rule | Meaning | Unit/Type | Typical Range of Impact |
|---|---|---|---|
| Computer Algebra System (CAS) | Ability to solve algebra symbolically, simplify expressions, etc. | Software Feature | Leads to immediate prohibition (e.g., TI-Nspire CAS, HP Prime). |
| QWERTY Keyboard | A keyboard layout like a computer’s. | Hardware Feature | Prohibited on all devices. |
| Wireless/Internet Access | Wi-Fi, Bluetooth, or any communication capability. | Hardware Feature | Strictly prohibited. |
| Paper Tape or Noise | Calculators that can print or make sounds. | Hardware Feature | Must be modified (tape removed, sound off). |
| Infrared Port | Allows communication between calculators. | Hardware Feature | Must be covered with opaque tape (e.g., HP 38G/39G/48G series). |
Practical Examples
Example 1: A Permitted Calculator
- Input: TI-84 Plus
- Logic: The model does not contain “CAS”, “TI-89”, “TI-92”, or other prohibited keywords. It is a standard graphing calculator widely accepted.
- Result: Permitted. This calculator is on the list of ACT accepted calculators and is a popular choice for students.
Example 2: A Prohibited Calculator
- Input: TI-Nspire CAS
- Logic: The model name explicitly contains “CAS” (Computer Algebra System). This is a prohibited feature.
- Result: Prohibited. Calculators with CAS functionality are not allowed on the ACT. However, the non-CAS version, the TI-Nspire, is permitted.
How to Use This ACT Accepted Calculators Checker
Using this tool is straightforward. Follow these steps to check your device:
- Enter the Model: Type the full model name of your calculator into the input field above. For instance, instead of just “TI”, enter “TI-30XIIS”.
- Check Status: Click the “Check Status” button to run the analysis against the known ACT math calculator rules.
- Interpret Results: The tool will display one of three results: Permitted, Prohibited, or Needs Modification. It will also provide a brief explanation for the outcome.
- Disclaimer: Always double-check with the official ACT calculator policy for the most current rules before your test.
Key Factors That Affect ACT Calculator Acceptance
Understanding the details of the policy can help you choose the right tool. Here are key factors that determine if a calculator is accepted:
- Computer Algebra System (CAS): This is the most common reason for a calculator to be banned. Models like the TI-89, TI-92, and HP Prime are prohibited because they can solve complex algebra problems on their own.
- QWERTY Keypads: Any calculator with a keyboard laid out like a computer (QWERTY) is not allowed.
- Communication Devices: Calculators with wireless, infrared, or other communication abilities are banned or require modification. The HP 38G, 39G, and 48G series need their infrared ports covered with tape.
- External Devices: You cannot use a calculator on a phone, tablet, or laptop. Check out our guide on ACT vs SAT comparison for more test details.
- Noise and Printing: Calculators that make noise must be silenced, and those with paper printers must have the tape removed.
- Power Source: Calculators that need an electrical outlet are prohibited. Make sure your device has fresh batteries!
Frequently Asked Questions (FAQ)
Is the TI-84 Plus CE an ACT accepted calculator?
Yes, the TI-84 Plus CE is permitted on the ACT. It is one of the most popular and recommended graphing calculators for the test.
What is the difference between the TI-Nspire and the TI-Nspire CAS?
The TI-Nspire (non-CAS) is allowed, but the TI-Nspire CAS is prohibited. The “CAS” model includes a Computer Algebra System, which is a banned feature.
What should I do if my calculator needs modification?
If your calculator has an infrared port (like some older HP models), cover it with opaque tape. If it makes noise, turn the sound off. If it has a paper tape, remove it. Refer to our test day checklist to make sure you’re prepared.
Can I share my calculator with another student?
No, sharing calculators during the test is not permitted and can lead to dismissal.
Are all scientific calculators allowed on the ACT?
Almost all scientific calculators are allowed. For example, the TI-30XIIS and Casio FX-115 are perfectly fine. Prohibited models are almost exclusively advanced graphing calculators. All TI scientific calculators are approved.
What happens if I bring a prohibited calculator?
Testing staff will confiscate the calculator, and you may be dismissed from the test center and have your score voided.
Do I need a calculator for the ACT math section?
While all problems can technically be solved without a calculator, it is highly recommended. A familiar calculator can save significant time and improve accuracy. An online math tutor can help you practice effectively.
Where can I find the official list of ACT accepted calculators?
The ACT maintains the official policy on its website. Our tool is based on this policy, but you should always refer to the official source for final confirmation.
