ACT® Calculator Policy Tool
Are you wondering if your calculator can be used on the ACT test? The official **ACT Calculator Policy** has specific rules about which devices are permitted, which are prohibited, and which require modification. Using a non-compliant calculator can lead to dismissal from the test. This tool and guide will help you understand the complete **ACT Calculator Policy** to ensure you’re prepared for test day.

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 ACT exam. This policy specifies which calculators are allowed, which are strictly forbidden, and which are permitted only after specific modifications. Calculators are only allowed during the Mathematics section of the test; they are not permitted for the English, Reading, or Science sections. The core purpose of the policy is to prevent any student from having an unfair advantage through devices with advanced functionalities like Computer Algebra Systems (CAS) or communication capabilities. Adhering to the **ACT Calculator Policy** is the student’s responsibility, and failure to do so can result in dismissal from the testing center and cancellation of scores.
Who Should Use This Policy Guide?
This guide is essential for any student preparing to take the ACT test. Whether you own a basic four-function calculator or a sophisticated graphing calculator, you must verify its compliance. Test proctors are trained to check calculators and will enforce the **ACT Calculator Policy** strictly.
Common Misconceptions
A common misconception is that all graphing calculators are banned, which is untrue. Many popular models, like the TI-84 Plus series, are perfectly acceptable. Another myth is that a calculator is required to succeed on the ACT Math test. In reality, every single problem on the test can be solved without a calculator.
ACT Calculator Policy Rules Explained
The foundation of the **ACT Calculator Policy** is straightforward: you can use a four-function, scientific, or graphing calculator, provided it is not on the prohibited list. The main restrictions target specific features that give users an unfair advantage. Understanding these rules is more important than memorizing a list of models.
Rule Breakdown Table
The following table breaks down the core rules of the **ACT Calculator Policy**. A calculator is generally prohibited if it has any of the features in the ‘Prohibited’ column. Some devices can be made compliant with the modifications listed.
| Feature Type | Status & Rule | Examples of Affected Models |
|---|---|---|
| Computer Algebra System (CAS) | Prohibited. Calculators that can symbolically solve algebraic equations are banned. | TI-89, TI-92, TI-Nspire CAS, HP Prime, Casio ClassPad series. |
| QWERTY Keyboard | Prohibited. Any calculator with a letter keyboard in QWERTY format is not allowed. | Devices with integrated keyboards. |
| Communication Devices | Prohibited. Calculators built into cell phones, tablets, or laptops are banned. | Smartphones, Smartwatches, Laptops. |
| Infrared Data Port | Modification Required. The port must be completely covered with opaque tape. | HP 38G Series, HP 39G Series, HP 48G. |
| Paper Tape | Modification Required. The paper tape must be removed before the test. | Printing calculators. |
| Makes Noise | Modification Required. The sound must be turned off. | Calculators with audio features. |
| Needs Power Cord | Prohibited. Calculators that need an external power source during the test are not allowed. | Older models requiring an AC adapter. |
Calculator Status Distribution (Common Models)
Practical Examples of the ACT Calculator Policy
Let’s look at two common scenarios students face when checking the **ACT Calculator Policy**.
Example 1: The Compliant Student
- Calculator Model: Texas Instruments TI-84 Plus CE
- Analysis: This model does not have a built-in Computer Algebra System (CAS). It does not have a QWERTY keyboard. It is one of the most popular and widely approved calculators for the ACT.
- Outcome: Permitted. The student can bring this calculator to the test center without any modifications.
Example 2: The Prohibited Calculator
- Calculator Model: Texas Instruments TI-89 Titanium
- Analysis: The **ACT Calculator Policy** explicitly prohibits all calculators with model numbers that begin with TI-89 or TI-92. This is because the TI-89 has a powerful Computer Algebra System (CAS), which can solve equations symbolically, a feature banned by the ACT.
- Outcome: Prohibited. The student must find a different, compliant calculator for the test.
How to Use This ACT Calculator Policy Checker
Our interactive tool is designed to give you a quick determination based on the official **ACT Calculator Policy**. Follow these steps:
- Enter Model: Type the full model name of your calculator (e.g., “TI-Nspire CX”) into the input field.
- View Results: The tool will instantly provide a status: Permitted, Prohibited, or Modification Required.
- Check Details: The intermediate results show *why* the decision was made, checking for CAS, QWERTY keyboards, and other specific rules.
- Read Explanation: A detailed explanation provides context based on the current **ACT Calculator Policy**. For more details on test day rules, see our guide to ACT Test Day Rules.
Key Factors That Affect Calculator Permissibility
Understanding these factors is crucial for following the **ACT Calculator Policy**.
- Computer Algebra System (CAS): This is the most significant factor. If a calculator can perform symbolic algebra (e.g., solve for x), it is banned. This is because it goes beyond numerical calculation.
- QWERTY Keypad: Calculators with typewriter-like keyboards are prohibited to prevent students from storing notes.
- External Communication: Any feature that allows the calculator to communicate with other devices (like infrared ports or Wi-Fi) is either banned or must be disabled/covered.
- Power Source: The calculator must be battery-powered. Devices needing an electrical outlet are not allowed in the test room.
- Programs and Documents: Even on a permitted calculator like a TI-84, you must remove any programs or documents that provide CAS functionality or contain notes. You can find help on SAT vs ACT calculator policies here.
- Physical Modifications: Calculators with paper-tape printers must have the tape removed. Those with sound must be muted.
Frequently Asked Questions (FAQ) about the ACT Calculator Policy
1. Is the TI-Nspire allowed on the ACT?
It depends. The TI-Nspire (non-CAS) model is permitted. However, the TI-Nspire CAS model is strictly prohibited due to its computer algebra system. You must check your specific model carefully.
2. Can I use a calculator on the ACT Science section?
No. Calculators are only permitted during the Math section of the ACT. They are not allowed during the Reading, English, or Science sections.
3. What happens if I bring a prohibited calculator?
If a test proctor finds you are using a prohibited calculator, you may be dismissed from the test, and your score will be invalidated. It is your responsibility to ensure your calculator complies with the **ACT Calculator Policy**.
4. Do I need to clear the memory on my TI-84?
The ACT policy requires you to remove any programs that have CAS functionality. While proctors may not always check, it is best practice to clear any non-essential programs to be safe. Explore our ACT Prep Courses for more tips.
5. Are four-function calculators good enough for the ACT?
Yes, they are allowed and can be used to solve any problem on the test. However, a scientific or graphing calculator can be more efficient for complex calculations involving trigonometry or logarithms.
6. Is the calculator policy the same for digital and paper ACT tests?
Yes, the **ACT Calculator Policy** applies to both paper and digital versions of the test. For digital tests, an on-screen calculator may also be available.
7. Can I share my calculator with another student?
No. Sharing calculators during the test is strictly forbidden and can lead to disqualification for both students.
8. Where can I find the official ACT Calculator Policy?
The most current version of the policy is always available on the official ACT website (act.org). It’s a good idea to check it before your test date for any updates. Our ACT Math Practice page has more resources.
