ACT Calculator Permissibility Checker
Instantly determine if you can use your calculator on the ACT Math test. Answer the questions below based on the official ACT calculator policy.
Is Your Calculator Allowed?
Models like TI-89, TI-92, TI-Nspire CAS, and HP Prime have CAS.
Calculators with typewriter-like keyboards are prohibited.
No phones or general-purpose electronic devices are allowed.
Calculators must be battery-operated.
Devices with communication capabilities are not permitted.
What is the ACT Calculator Policy?
The central question for many students is, “act can you use a calculator on the test?” The answer is yes, but only on the Mathematics section, and only if your calculator complies with the official ACT policy. This policy is designed to ensure fairness and test security. The core principle is that you can use a wide range of calculators, including most graphing calculators, but certain features are strictly forbidden. The ACT doesn’t maintain a list of *approved* calculators; instead, it provides a list of *prohibited* calculators and features. If your calculator is not on the prohibited list, it’s generally allowed.
ACT Calculator Formula: Prohibited vs. Permitted
Think of the permissibility as a simple logical formula. A calculator is permitted IF AND ONLY IF it meets all the required conditions. It must NOT have any prohibited features.
Permitted vs. Prohibited Features
Understanding the specific rules is key to knowing if you can use a calculator on the ACT. Here’s a breakdown of the core variables in the decision.
| Variable / Feature | Meaning | Status | Typical Examples |
|---|---|---|---|
| Computer Algebra System (CAS) | Ability to solve algebraic equations symbolically. | Prohibited | TI-89, TI-Nspire CAS, HP Prime |
| Graphing Functionality | Ability to plot equations on a coordinate plane. | Permitted | TI-83, TI-84 Plus |
| QWERTY Keyboard | A typewriter-style keyboard layout. | Prohibited | Calculators with alphabet keys in a QWERTY format |
| Wireless Communication | Internet, Bluetooth, or infrared capabilities. | Prohibited | Smartphones, tablets, smartwatches |
| External Power | Requires a wall outlet to function. | Prohibited | Any device with a power cord |
Practical Examples of ACT Calculator Checks
Example 1: A Permitted Calculator
- Calculator Model: Texas Instruments TI-84 Plus CE
- Inputs: No CAS, No QWERTY keyboard, Not part of a phone, Battery-operated, No wireless.
- Result: LIKELY PERMITTED. This is one of the most common and widely accepted graphing calculators for the ACT.
Example 2: A Prohibited Calculator
- Calculator Model: Texas Instruments TI-89 Titanium
- Inputs: Has CAS, No QWERTY keyboard, Not part of a phone, Battery-operated, No wireless.
- Result: NOT PERMITTED. The presence of a Computer Algebra System (CAS) makes this calculator prohibited.
How to Use This ACT Calculator Permissibility Checker
Using this tool is straightforward and helps you quickly assess if your device is test-day ready.
- Answer Each Question: Go through each of the five questions in the calculator, selecting ‘Yes’ or ‘No’ based on your calculator’s features.
- Check the Helper Text: If you’re unsure about a feature, read the small helper text below each dropdown for examples.
- Click ‘Check My Calculator’: Once you’ve answered all questions, click the blue button.
- Review the Result: The tool will provide an instant result, either “LIKELY PERMITTED” in green or “NOT PERMITTED” in red, along with a clear explanation for the decision. The ACT calculator policy is the ultimate source.
Key Factors That Affect Your ACT Calculator Choice
- Familiarity: The best calculator is one you know how to use well. Don’t buy a new, complex calculator right before the test.
- Battery Life: Ensure your calculator has fresh batteries. It’s a good idea to bring a backup calculator or extra batteries.
- CAS Functionality: This is the most common reason a graphing calculator is prohibited. Double-check your model is not a CAS version.
- Physical Condition: Make sure your calculator doesn’t make noise and that any paper tape is removed.
- Programs: While some programs are allowed, any that use a CAS are not. Proctors may check and ask you to clear your calculator’s memory.
- Digital vs. Paper Test: If you take the digital ACT, an on-screen calculator (Desmos) is provided, but you can still bring your own approved handheld one.
Frequently Asked Questions (FAQ) about ACT Calculators
- 1. Can you use a calculator on all sections of the ACT?
- No, calculators are only permitted on the Mathematics test. They are not allowed on the English, Reading, or Science sections.
- 2. Is there an official list of approved calculators?
- No, the ACT provides a list of prohibited features and specific models to avoid. If your calculator isn’t on the prohibited list, it is generally allowed.
- 3. Are graphing calculators allowed on the ACT?
- Yes, most graphing calculators are allowed, provided they do not have a Computer Algebra System (CAS). The TI-84 Plus is a very popular choice.
- 4. What happens if I bring a prohibited calculator?
- A proctor will check your calculator. If it’s prohibited, you will not be allowed to use it. In some cases, you could be dismissed from the test.
- 5. Can I use my phone’s calculator if it’s in airplane mode?
- No. All phones, smartwatches, and other communication devices are strictly prohibited, regardless of their mode.
- 6. Do I have to clear my calculator’s memory?
- You must remove any programs that have CAS functionality. Proctors may inspect your calculator and ask you to clear its memory.
- 7. What is a Computer Algebra System (CAS)?
- A CAS is a sophisticated program that can perform symbolic manipulation of expressions, like solving for variables in an equation. This is considered an unfair advantage. To determine if act can you use a calculator like this, check the model number (e.g., TI-Nspire CAS is prohibited, but the standard TI-Nspire is not).
- 8. Does the ACT provide a calculator?
- No, you are responsible for bringing your own permitted calculator. The only exception is the digital version of the test, which has an on-screen calculator available.
