An essential tool to check if your calculator model is permitted on test day.
ACT Calculator Policy Checker
Answer the questions below about your calculator’s features to determine if you can use your calculator on the ACT. The official policy prohibits devices with features that might provide an unfair advantage.
Understanding the ACT Calculator Policy
Navigating the rules for test day can be stressful. A frequent question students ask is, “can i use my calculator on the act?”. The answer is yes, but with important restrictions. The ACT allows a calculator on the Mathematics Test only to ensure fairness and test security. Understanding these rules is crucial to avoid having your calculator confiscated or being dismissed from the test.
What is the primary keyword?
The primary keyword for this topic is “can i use my calculator on the act“. This phrase represents the core user question. Students need to know if their specific calculator—be it a basic, scientific, or graphing model—is allowed. The ACT’s policy is designed to prevent unfair advantages, so any device that can store notes, access the internet, or perform symbolic algebra (through a Computer Algebra System) is generally banned.
This calculator and guide are for any student preparing for the ACT who wants to confirm if their device is compliant. Misunderstanding the rules can lead to significant issues on test day, so a final check is always a good idea.
The ACT Calculator Rules Explained
The calculation to determine if a calculator is permitted is not a mathematical formula but a checklist of prohibited features. The logic is simple: if the calculator has any of the explicitly banned features, it is not allowed. The question “can i use my calculator on the act?” is answered by evaluating these rules.
The core rule is: Any 4-function, scientific, or graphing calculator is permitted as long as it does NOT have any of the prohibited features listed below.
| Feature/Rule | Explanation | Is it Permitted? | Typical Range of Models |
|---|---|---|---|
| Part of another device | Calculators on phones, laptops, or tablets are banned. | No | Any smartphone or computer |
| QWERTY Keyboard | Typewriter-style keyboards are prohibited. | No | Older organizer-style calculators |
| Computer Algebra System (CAS) | Calculators that can solve algebra symbolically are banned. | No | TI-89, TI-92, TI-Nspire CAS, HP Prime |
| Wireless Communication | Devices with Wi-Fi, Bluetooth, or internet access are banned. | No | Modern smart devices |
| Needs External Power | Calculators that must be plugged in are not allowed. | No | Desktop printing calculators |
| Makes Noise | Allowed only if sound is disabled. | With Modification | Some talking calculators |
| Paper Tape | Allowed only if the paper roll is removed. | With Modification | Printing calculators |
Practical Examples
Example 1: Texas Instruments TI-84 Plus CE
A student has a TI-84 Plus CE and wants to know, “can i use my calculator on the act?”. They use the checker:
- Is it a phone/laptop? No.
- Has QWERTY keyboard? No.
- Has CAS? No. (This is the key difference from the banned TI-Nspire CAS).
- Has wireless? No.
Result: PERMITTED. The TI-84 Plus series is one of the most common and widely accepted calculators for the ACT.
Example 2: HP Prime
Another student has an HP Prime and asks the same question.
- Is it a phone/laptop? No.
- Has QWERTY keyboard? No.
- Has CAS? Yes. The HP Prime has a powerful Computer Algebra System.
Result: PROHIBITED. Due to its CAS functionality, the HP Prime is explicitly banned by the ACT. The student will need to acquire a different, non-CAS calculator. To find out more, check the {related_keywords}.

Key Factors That Affect Calculator Permission
When you ask “can i use my calculator on the act?”, several factors come into play. Here are the most critical ones:
- Computer Algebra System (CAS): This is the most common reason for a graphing calculator to be banned. CAS can perform symbolic manipulations (like solving for x), which the ACT wants students to do themselves.
- QWERTY Keyboard: Any calculator with a typewriter-style keyboard is forbidden, as it could potentially be used to store notes.
- Communication Technology: Internet, Wi-Fi, Bluetooth, or any wireless capability is an automatic disqualifier.
- Device Type: The calculator must be a standalone device. You cannot use an app on your phone, tablet, or smartwatch. Learn about {related_keywords}.
- Power Source: The device must be battery-operated. Anything requiring an external power cord is not allowed.
- Modifiable Features: Some features, like sound or a paper tape, are acceptable only if they are disabled or removed before the test begins.
Frequently Asked Questions (FAQ)
1. Can I use a TI-Nspire on the ACT?
It depends. The TI-Nspire (non-CAS) is permitted, but the TI-Nspire CAS is strictly prohibited. You must check your model carefully.
2. What if my calculator has games on it?
The ACT states that you may have to clear the memory of your calculator, including any programs. It’s best to remove all non-essential programs and games before test day to avoid any issues.
3. Is a scientific calculator good enough for the ACT?
Yes. All problems on the ACT Math Test can be solved without a calculator, but a good scientific calculator is sufficient for the calculations required. A graphing calculator is not a necessity.
4. What happens if I bring a prohibited calculator?
The testing staff will confiscate the calculator, and you will have to take the Math Test without it. In some cases, you could be dismissed from the test. Thinking about the “can i use my calculator on the act” question beforehand is vital. See our guide to {related_keywords}.
5. Can I share a calculator with a friend?
No. Sharing calculators is not permitted under any circumstances.
6. Does the ACT provide calculators?
No, you are responsible for bringing your own approved calculator. Test centers do not provide them.
7. Do I need to clear my calculator’s memory?
It is a strong recommendation. Proctors may inspect your calculator, and having programs or formulas stored could be considered cheating. It’s best to clear the memory to be safe.
8. Is the calculator policy the same for the SAT?
No, the SAT and ACT have different calculator policies. You should always check the specific rules for the test you are taking. For details, read about the {related_keywords}.
