ACT Calculator Policy Checker
Wondering “can you use calculators on the ACT”? This tool helps you quickly determine if your calculator model and its features are likely permitted on test day.
Enter the model name/number of your calculator.
Check any features your calculator has. These are common reasons for a calculator to be banned.
What is the ACT Calculator Policy?
The question of can you use calculators on the ACT is a critical one for test-day success. The ACT allows calculators only on the Mathematics section. However, not all calculators are created equal in the eyes of the ACT administrators. The policy is designed to ensure fairness and prevent any student from having an unfair advantage. Essentially, you can use most four-function, scientific, and graphing calculators, as long as they aren’t on the official prohibited list and don’t have specific banned features.
Common misunderstandings can cause major issues. For example, a calculator model might have a standard version that is allowed (like the TI-Nspire) and a CAS version that is banned (the TI-Nspire CAS). It is the student’s responsibility to ensure their specific device is compliant. Furthermore, calculator apps on phones, tablets, or smartwatches are strictly forbidden.
ACT Calculator Rules: Permitted vs. Prohibited Features
Understanding the specific rules is the key to knowing if your device is an ACT approved calculator. The main restrictions revolve around features that can solve complex algebraic equations automatically or communicate with other devices. Here is a breakdown of the core rules.
| Feature Type | Permitted Status | Explanation & Notes |
|---|---|---|
| Basic & Scientific Functions | Permitted | All four-function and standard scientific calculators are allowed. |
| Graphing Capabilities | Permitted | Most graphing calculators (like the TI-84 Plus series) are allowed. |
| Computer Algebra System (CAS) | Prohibited | Calculators that can symbolically solve algebra (e.g., find ‘x’ in 3x+5=11) are banned. This is the most common reason for a calculator to be prohibited. |
| QWERTY-style Keyboard | Prohibited | Calculators with a letter keypad arranged like a computer keyboard are not allowed. |
| Wireless Communication | Prohibited | Any device with Wi-Fi, Bluetooth, or an infrared data port that isn’t covered is banned. |
| Makes Noise / Has Paper Tape | Modification Required | The sound must be muted, and any paper tape must be removed before the test. |
| Requires Power Cord | Prohibited | Calculators must be battery-operated. Those needing an external power source are not allowed. |
Practical Examples
Example 1: A Permitted Calculator
- Input Model: TI-84 Plus CE
- Feature Check: Does not have CAS, a QWERTY keyboard, or wireless capabilities.
- Result: This calculator is Permitted on the ACT. The TI-84 series is one of the most popular and widely accepted choices for college entrance exams.
Example 2: A Prohibited Calculator
- Input Model: TI-89 Titanium
- Feature Check: This calculator has a built-in Computer Algebra System (CAS).
- Result: This calculator is Prohibited. Even though it’s a powerful graphing calculator, its CAS functionality gives an unfair advantage according to ACT rules.
How to Use This ACT Calculator Policy Checker
Navigating the ACT math test rules can be tricky. This tool simplifies the process into a few easy steps:
- Enter Your Calculator Model: Type the model name (e.g., “TI-84 Plus”) into the first input field. While this tool has a list of common prohibited models, the feature check is most important.
- Check for Prohibited Features: Carefully review the checklist. Select any box that describes a feature your calculator has. Be honest—it’s better to know now than on test day. The most critical feature to check is the Computer Algebra System (CAS).
- Check Eligibility: Click the main button to see your result. The tool will give you an immediate “Permitted” or “Prohibited” status based on your inputs.
- Review the Explanation: The output will provide a reason for the result, helping you understand which rule applies to your device. This is crucial for learning the policy.
Key Factors That Affect ACT Calculator Approval
Several factors determine whether you can use a calculator on the ACT. Here are the most important ones to consider:
- Computer Algebra System (CAS): This is the number one disqualifying feature. CAS calculators can perform symbolic manipulation, which is against ACT rules.
- QWERTY Keypad: Calculators with typewriter-like keyboards are banned to prevent the storage of notes.
- Communication Technology: Any form of wireless communication (Bluetooth, Wi-Fi) or infrared port is prohibited.
- External Power Source: The calculator must be battery-powered. Devices that need to be plugged in are not allowed.
- Noise and Printing: Calculators that make noise must be muted, and those with paper printers must have the tape removed.
- Programs and Documents: You must remove any programs from your calculator that have CAS functionality. It’s recommended to clear your calculator’s memory before the test.
ACT Calculator Policy Decision Flow
Frequently Asked Questions (FAQ)
Can I use a TI-84 Plus on the ACT?
Yes, all versions of the Texas Instruments TI-84 Plus, including the TI-84 Plus CE, are permitted on the ACT. It is one of the most recommended graphing calculators for the test.
What happens if I bring a prohibited calculator?
If you are found with a prohibited calculator, the testing staff may dismiss you from the test, and your score will be voided. It is crucial to check your calculator before test day.
Are scientific calculators allowed?
Yes, all standard scientific calculators are allowed on the ACT. Models like the TI-30XS MultiView are excellent choices if you do not need graphing functionality.
Can I share my calculator with a friend during the test?
No, sharing calculators is strictly prohibited under any circumstances. You should also bring a backup calculator or extra batteries in case your primary one fails.
Do I need a graphing calculator for the ACT?
No, a graphing calculator is not required. According to the ACT, every single math problem can be solved without a calculator. However, many students find a familiar calculator useful for saving time and checking work. A guide on how to study for the ACT can help you strategize.
Are there any programs I need to remove from my calculator?
Yes, you must remove any programs that provide Computer Algebra System (CAS) functionality. While games like Tetris are not explicitly banned, proctors may check your calculator’s program memory and it’s best practice to clear it to avoid any issues.
Can you use calculators on the ACT science section?
No, calculators are not permitted on the ACT Science, Reading, or English sections. They are only allowed during the Mathematics section.
Does the ACT provide a calculator?
No, you are responsible for bringing your own ACT-approved calculator. For computer-based tests, an on-screen calculator may be available, but you should not rely on it if you prefer your handheld device.
