What is the ACT Calculator Policy?
The ACT calculator policy outlines the rules for which calculators are, and are not, allowed during the math portion of the ACT exam. The purpose of this policy is to ensure fairness and prevent any student from having an unfair advantage through technology. While you can use a graphing calculator on the ACT, not all models are permitted. The policy specifically bans calculators with features that can solve complex algebraic equations symbolically, store large amounts of text, or communicate with other devices. Understanding whether you can use your graphing calculator on the ACT is a critical part of test preparation.
This policy is for everyone taking the ACT to ensure a level playing field. Common misconceptions are that all graphing calculators are banned, or that any scientific calculator is fine. The reality is more nuanced; the specific model and its features determine its eligibility. For example, most TI-84 models are allowed, but the TI-89 is strictly prohibited because of its Computer Algebra System (CAS).
Understanding the ACT’s Calculator Rules
The core of the ACT calculator policy revolves around prohibiting devices that can perform tasks beyond numerical calculation. The rules can be broken down into three main categories: Permitted, Prohibited, and Permitted with Modification. Knowing if you can use a graphing calculator on the ACT depends entirely on which category your device falls into.
| Category | Description | Examples |
|---|---|---|
| Permitted | Includes most standard scientific and graphing calculators that do not have prohibited features. | TI-83, TI-84 Plus, TI-Nspire (non-CAS), Casio fx-9750GII. |
| Prohibited | Calculators with Computer Algebra Systems (CAS), QWERTY keyboards, wireless capability, or those needing an electrical outlet are banned. | TI-89, TI-92, HP Prime, Casio ClassPad series. |
| Permitted with Modification | Some devices are allowed only if certain features are disabled (e.g., removing paper tape, muting sound, covering infrared ports). | Calculators with paper tape or infrared data ports. |
Practical Examples of Allowed and Prohibited Calculators
Example 1: The Permitted Calculator (TI-84 Plus CE)
A student has a Texas Instruments TI-84 Plus CE. They use our checker and it shows “PERMITTED”. This is because the TI-84 Plus series is explicitly allowed by the ACT. It can graph functions, perform statistical analysis, and handle complex numerical calculations, but it does not have a built-in Computer Algebra System (CAS). This is a perfect example of a powerful tool that still falls within the rules of the ACT calculator policy. You can confidently use this graphing calculator on the ACT.
Example 2: The Prohibited Calculator (TI-89 Titanium)
Another student has a Texas Instruments TI-89 Titanium. Our checker immediately flags this as “PROHIBITED”. The reason is that the TI-89 features a powerful CAS, which can solve algebraic equations symbolically (e.g., solving for ‘x’ in ‘2x + y = 10’ to get ‘x = (10-y)/2’). This capability is against the ACT’s fairness policy, as it performs the algebraic work for the student. Test proctors are trained to spot and confiscate these models.
How to Use This ACT Calculator Policy Checker
Using this tool is straightforward and designed to give you a quick assessment of your calculator’s status before test day.
- Enter Your Calculator Model: Type the full model name of your calculator (e.g., “Casio fx-9750GII”) into the input field.
- Check Status: Click the “Check Status” button. The tool will analyze the model name against a database of known permitted and prohibited devices.
- Review Results: The result box will display one of three statuses: PERMITTED, PROHIBITED, or UNCERTAIN. It will also provide a brief reason for the determination, helping you understand the specific rule that applies. This helps you know if you can use your graphing calculator on the ACT.
- Consult Official Resources: For “UNCERTAIN” results, or for final confirmation, always visit the official ACT website. Our tool is a guide, but the official policy is the final word. See our ACT registration guide for more test day tips.
Key Factors That Affect Calculator Eligibility
Several key features determine whether a calculator is allowed. Understanding these factors is crucial for following the ACT calculator policy.
- Computer Algebra System (CAS): This is the most common reason for a calculator to be banned. A CAS can manipulate algebraic expressions symbolically, which is a prohibited function.
- QWERTY Keyboard: Any calculator with a letter keyboard in the standard QWERTY layout is not allowed.
- Wireless or Communication Capability: Devices with Wi-Fi, Bluetooth, or any form of wireless communication are strictly forbidden.
- Need for an Electrical Outlet: All calculators must be battery-operated.
- Programs and Applications: While many calculators can store programs, any program that adds CAS functionality must be removed before the test. Test proctors may inspect your calculator’s apps.
- Noise and Printing: Calculators that make noise must be muted, and those with paper printers must have the paper roll removed. Learn more about the ACT math formulas you’ll need to know.
Frequently Asked Questions (FAQ)
You can use the standard TI-Nspire and TI-Nspire CX models. However, the TI-Nspire CAS and CX CAS models are strictly prohibited. It is critical to check for the “CAS” designation on the calculator’s face.
Test staff will confiscate the calculator, and you may be dismissed from the test, having your score voided. It is your responsibility to bring a permitted device.
No. The ACT states that every math problem can be solved without a calculator. However, a familiar graphing calculator can be a significant time-saver, which is why knowing the ACT calculator policy is so important. Check out our SAT vs ACT comparison to see how policies differ.
Yes, all four-function and scientific calculators are allowed, as long as they do not have any of the prohibited features mentioned above (like a QWERTY keyboard).
No. Sharing calculators is not permitted during the test. You should bring your own, plus a backup if possible.
No, you are responsible for bringing your own calculator. Testing staff will not provide them. It’s a key part of your test day preparation, just like knowing whether you can use a graphing calculator on the ACT.
CAS stands for Computer Algebra System. It’s a sophisticated program that allows a calculator to solve and simplify algebraic expressions, rather than just computing numbers. For example, it can find the antiderivative of a function in calculus. This is why it’s a focus of the ACT calculator policy.
Yes. While programs are allowed, you must remove any program that gives the calculator CAS-like functionality. Proctors may check the applications on your calculator. It is safest to remove all non-essential programs before test day. Check our list of the best calculators for college board exams.
