What is the ACT Calculator Policy?
The ACT calculator policy is a set of rules designed to ensure fairness for all test-takers, prevent cheating, and maintain a secure testing environment. The fundamental question for many students is, **can you use a calculator on the act**? The answer is yes, but only on the Mathematics Test, and only if the calculator is an approved model. All problems on the math section can be solved without a calculator, but using a familiar and permitted tool can significantly improve speed and accuracy. Students are responsible for bringing their own approved calculator; testing staff will not provide them.
Common misconceptions are that all graphing calculators are banned or that you must use a specific brand. In reality, most four-function, scientific, and graphing calculators are allowed as long as they are not on the explicit prohibited list and don’t have certain features like a Computer Algebra System (CAS). The policy’s goal is to allow a useful tool, not a device that solves problems for the student.
ACT Calculator Rules Explained
The “formula” for determining if a calculator is allowed is a checklist of prohibited features. If a calculator has even one of these features without a permitted modification, it is not allowed. Understanding if **can you use a calculator on the act** involves checking your device against these rules. The core principle is that calculators cannot have features that give an unfair advantage, such as solving algebraic equations automatically or communicating with other devices.
| Variable / Feature | Meaning | Status | Typical Examples |
|---|---|---|---|
| Computer Algebra System (CAS) | Ability to solve algebraic expressions, simplify, or factor. | Prohibited | TI-89, TI-Nspire CAS, HP Prime |
| QWERTY Keyboard | A typewriter-style keyboard layout. | Prohibited | Calculators with this specific keyboard format. |
| External Communication | Features like Wi-Fi, Bluetooth, or infrared ports. | Prohibited | Phones, tablets, smartwatches. |
| External Power | Requires an electrical outlet to function. | Prohibited | Any calculator that is not battery-powered. |
| Noise / Sound | Makes audible tones. | Permitted if Muted | Calculators with key tones must be silenced. |
| Paper Tape | Prints a record of calculations. | Permitted if Tape is Removed | Old office-style calculators. |
Practical Examples (Real-World Use Cases)
Example 1: The Compliant Student (TI-84 Plus)
A student has a Texas Instruments TI-84 Plus. They use our checker: it has no CAS, no QWERTY keyboard, is battery-powered, and has no communication features. The result is **Permitted**. The student can bring this calculator to the test without any modifications and be confident they are following the rules. The TI-84 Plus is a popular choice because it offers powerful graphing capabilities without violating the ACT policy.
Example 2: The Prohibited Calculator (TI-Nspire CAS)
Another student has a Texas Instruments TI-Nspire CAS. When they check the features, they select “Yes” for “Does it have a Computer Algebra System (CAS)?”. The checker immediately flags the calculator as **Prohibited**. Even though the calculator is otherwise acceptable, the CAS functionality is explicitly banned. This student would need to acquire a different, non-CAS calculator, like the standard TI-Nspire (non-CAS version) or a TI-84, to comply with the ACT policy.
How to Use This ACT Calculator Policy Checker
Using this tool is a straightforward way to determine if **can you use a calculator on the act**. Follow these steps:
- Answer the Questions: Go through each dropdown menu and select ‘Yes’ or ‘No’ based on your calculator’s features. Be honest and thorough.
- Review the Primary Result: The large colored box at the top of the results will give you an immediate answer: “Permitted,” “Prohibited,” or “Permitted with Modifications.”
- Check the Breakdown: The “Compliance Breakdown” list shows you which specific rules your calculator passed or failed. This is crucial for understanding *why* a calculator is not allowed.
- Take Action: If your result is “Prohibited,” you must find a different calculator for test day. If it’s “Permitted with Modifications,” make sure you perform the required actions (e.g., remove paper tape, cover an infrared port) before you go to the testing center.

Key Factors That Affect ACT Calculator Eligibility
Several key factors determine whether you can bring your calculator to the ACT. Understanding these factors is essential for any student asking, “**can you use a calculator on the act**?”.
- Computer Algebra System (CAS): This is the most common reason a graphing calculator is prohibited. A CAS can perform symbolic algebra, like factoring `x^2 – 4` into `(x-2)(x+2)`. Prohibited models include the TI-89 and HP Prime.
- QWERTY Keyboard: Any calculator with a keyboard laid out like a computer’s is banned. This is to prevent the storage of notes.
- Communication Technology: Any device that can connect to the internet, other devices via Bluetooth, or even use infrared ports (unless covered) is strictly forbidden. This includes all smartphones, tablets, and smartwatches.
- Power Source: The calculator must be battery-operated and cannot require an external power cord during the test.
- Physical Modifications: Some older or specialized calculators are allowed only if modified. This includes removing paper tape, muting sounds, and covering infrared ports with opaque tape.
- Prohibited List: The ACT publishes an official, though not exhaustive, list of specifically banned calculator models. It’s always a good idea to check your model number against this list on the official ACT website. A good resource for this is the {related_keywords} list.
Frequently Asked Questions (FAQ)
1. Can I use a TI-84 Plus on the ACT?
Yes, the entire TI-84 Plus family (including the Plus, C Silver Edition, and CE) is permitted on the ACT because it does not have a Computer Algebra System (CAS). It is one of the most popular choices for students. You should still learn about our {related_keywords} guide.
2. Is the TI-Nspire allowed on the ACT?
It depends. The standard TI-Nspire and TI-Nspire CX (non-CAS models) are allowed. However, the TI-Nspire CAS and CX CAS models are explicitly prohibited. Make sure you know which version you have.
3. Can you use a calculator on the ACT Science section?
No. Calculators are only permitted for the Mathematics section of the ACT. You must put your calculator away for all other sections, including Reading, English, and Science.
4. What happens if I’m caught with a prohibited calculator?
If a proctor finds you are using a prohibited calculator, you may be dismissed from the test, and your score will be voided. It is not worth the risk.
5. Do I have to clear the memory on my calculator?
The ACT policy requires that you remove any programs with CAS functionality. Proctors may inspect your calculator, and it’s recommended to clear any stored programs or documents to be safe. Some proctors may require you to clear your calculator’s RAM.
6. Does the ACT provide a calculator?
For paper-based tests, the ACT does not provide calculators. For computer-based tests, an on-screen calculator (like Desmos) may be available, but you are still allowed to bring your own approved handheld calculator. Exploring different {related_keywords} can help you decide.
7. Can I share my calculator with a friend during the test?
No, sharing calculators is strictly prohibited under any circumstances. It is recommended to bring a backup calculator and extra batteries in case your primary one fails.
8. Is a basic four-function calculator good enough for the ACT?
Yes, it is permitted. Since all questions can be solved without a calculator, a four-function device is sufficient. However, a scientific or graphing calculator can solve problems involving trigonometry, logarithms, and complex graphs much faster. This makes understanding **can you use a calculator on the act** crucial for time management. See our comparison of {related_keywords}.
