Can You Use a Calculator on the ACT?
An Interactive Policy Checker and SEO-Optimized Guide
Navigating the rules for what’s allowed on test day can be stressful. The ACT has a specific calculator policy that every student must follow. To simplify this, use our interactive ACT Calculator Policy Checker below to determine if your device is permitted on the Math Test. Just check the features your calculator has, and get an instant answer.
ACT Calculator Permissibility Checker
Calculators cannot be on a device with communication capabilities.
CAS functionality, which solves algebraic equations, is strictly prohibited.
Typewriter-like keyboards are not allowed.
Calculators must be battery-operated.
This is not an exhaustive list, but these are explicitly banned by the ACT.
What is the ACT Calculator Policy?
The ACT allows test-takers to use a calculator on the Mathematics Test only. This policy is designed to ensure fairness and test your mathematical reasoning skills, not just your ability to press buttons. While all math problems on the ACT can be solved without a calculator, using a familiar and permitted device can help you manage your time effectively and confirm your answers. You are responsible for bringing your own calculator, as they are not provided at the test center.
Permitted vs. Prohibited Features: The Official Rules
The core of the ACT calculator policy revolves around what a calculator can and cannot do. Generally, any four-function, scientific, or graphing calculator is acceptable as long as it’s not on the prohibited list. However, the most critical restriction is against calculators with a Computer Algebra System (CAS). The table below summarizes the key rules.
| Feature or Type | Status | Explanation |
|---|---|---|
| Computer Algebra System (CAS) | Prohibited | Calculators that can solve algebraic equations or perform symbolic manipulation (like the TI-89) are banned. |
| Graphing Capability (Non-CAS) | Permitted | Graphing calculators like the TI-83 Plus and TI-84 Plus series are allowed and very popular. |
| QWERTY Keyboard | Prohibited | Devices with a typewriter-style letter keyboard are not allowed. |
| Phones, Tablets, Laptops | Prohibited | No device that can communicate wirelessly or access the internet is permitted. |
| Makes Noise / Has Paper Tape | Modification Required | You must turn off the sound or remove the paper tape before the test begins. |
| Infrared Data Port | Modification Required | The port must be completely covered with opaque tape (e.g., duct tape). |
Practical Examples
Example 1: The Gold Standard (Permitted)
A student brings a Texas Instruments TI-84 Plus CE. Our calculator checker would show “PERMITTED.” This model is a graphing calculator but does not have a CAS, making it perfectly acceptable for the ACT. You can learn more about its features with this {related_keywords} guide.
Example 2: The Prohibited Model
A student brings a Texas Instruments TI-89 Titanium. Our checker would flag this as “PROHIBITED.” The TI-89 has a powerful Computer Algebra System, which is explicitly banned by the ACT. Bringing this would result in the student being unable to use it.
How to Use This “do you get to use a calculator on the act” Calculator
Using our policy checker is straightforward and designed to give you confidence before test day.
- Identify Features: Look at your calculator and identify its key functions. Does it have graphing capabilities? Do you know if it has a CAS? Check the model number.
- Select a-nswers: In the checker above, mark the checkboxes that apply to your device. If your model is on the prohibited list, select it from the dropdown.
- Review Results: The tool will immediately provide a “PERMITTED” or “PROHIBITED” status along with the specific reason for the result.

Key Factors That Affect Your Calculator Choice
- Familiarity: The best calculator is the one you already know how to use. Don’t buy a new, complex calculator right before the test.
- Battery: Ensure your calculator has fresh batteries. It’s wise to bring a backup calculator or extra batteries just in case.
- No CAS: This is the most important rule. Double-check that your calculator does not have a Computer Algebra System. Check out our {related_keywords} article for more details.
- Graphing Functions: A graphing calculator can be a powerful tool for solving problems related to functions and coordinate geometry.
- Programs: The ACT requires that you remove any programs with CAS functionality or documents from your calculator. Some proctors may ask to see that your calculator’s memory is cleared.
- Official Policy: Always check the official ACT website for the most current calculator policy before your test, as rules can change. This is a key part of understanding if do you get to use a calculator on the act.
Frequently Asked Questions (FAQ)
1. Is the TI-Nspire allowed on the ACT?
The standard TI-Nspire CX and CX II models are permitted. However, the TI-Nspire CX CAS model is prohibited.
2. Can I use my phone as a calculator?
No. All phones, smartwatches, laptops, tablets, or any device with communication capabilities are strictly prohibited.
3. What happens if I bring a prohibited calculator?
You will not be allowed to use it. In some cases, you could be dismissed from the test.
4. Do I need a graphing calculator for the ACT?
No, it is not required. All problems can be solved without one. However, a graphing calculator can be a very useful tool if you know how to use it.
5. Can I use a calculator on the ACT Science section?
No, calculator use is restricted to the Mathematics Test only.
6. What is a Computer Algebra System (CAS)?
A CAS is a sophisticated software that can find solutions to algebraic equations, simplify expressions, and perform calculus operations automatically. A {related_keywords} can explain more. This is why it’s not allowed on the ACT.
7. Do I need to clear the memory on my calculator?
The policy states that you must remove any programs that have CAS functionality. While not always enforced, it’s a good practice to clear your memory or be prepared for a proctor to inspect your device.
8. Where can I find the official ACT calculator policy?
For the most definitive and up-to-date information on whether do you get to use a calculator on the act, you should always visit the official ACT website.
