ACT Calculator Policy Checker
Can you use your calculator on the ACT? This tool helps you quickly determine if your calculator model is permitted, prohibited, or requires modification for the test.
Enter the model name/number. E.g., for a TI-84 Plus, enter “84 Plus”.
Please enter a model name.
Check this if your calculator can solve algebraic equations symbolically (e.g., shows ‘x’ in the answer). Models with “CAS” in the name have this.

What is the ACT Calculator Policy?
The question “can you use a calculator on the ACT” is a critical one for test-day success. The ACT calculator policy is a set of rules designed to ensure fairness and test security for all students. While you are allowed to use a calculator on the Math section of the ACT, not all calculators are permitted. The policy explicitly prohibits devices with certain functionalities, such as those that can communicate wirelessly, have typewriter-style (QWERTY) keyboards, or contain a Computer Algebra System (CAS). Understanding these rules is essential, as using a prohibited device can lead to dismissal from the test. Every math problem on the ACT can be solved without a calculator, but using a familiar and approved one can significantly improve your speed and accuracy.
Understanding the ACT’s Calculator Rules
The core of the ACT’s calculator policy revolves around prohibiting devices that give an unfair advantage. The most significant restriction is on calculators with a Computer Algebra System (CAS). A CAS can perform symbolic manipulation, like solving algebraic equations, which is a skill the ACT is designed to test. Models like the TI-Nspire CAS, TI-89, and HP Prime are banned for this reason. Another major rule is the ban on calculators with QWERTY keyboards, like a computer. This guide will help you determine if you can use your calculator on the ACT.
To ensure you’re compliant, check your model against the official rules. Here’s a breakdown of key features and their status:
| Feature | Description | ACT Status | Typical Range/Example |
|---|---|---|---|
| Computer Algebra System (CAS) | Solves symbolic algebra (e.g., solves for x). | Prohibited | TI-89, TI-Nspire CAS, HP Prime. |
| QWERTY Keyboard | A typewriter-style keyboard. | Prohibited | Calculators built into phones or PDAs. |
| Graphing Capability | Plots equations on a coordinate plane. | Permitted | TI-84 Plus series, Casio fx-9750GII. |
| Scientific Functions | Performs trigonometric, log, and exponential functions. | Permitted | TI-30XS, Casio fx-300ES Plus. |
| Infrared Data Port | Allows wireless data transfer between calculators. | Modification Required | HP 38G/39G/48G series (must cover port with tape). |
| Makes Noise | Beeps or makes other sounds. | Modification Required | Must turn off the sound. |
| Paper Tape | Prints calculations on a roll of paper. | Modification Required | Must remove the tape. |
Practical Examples (Real-World Use Cases)
Example 1: The Most Common Calculator
A student wants to know if they can use a calculator on the ACT and they own a Texas Instruments TI-84 Plus CE. They use the checker:
- Inputs: Brand = Texas Instruments, Model = 84 Plus CE, CAS = No, QWERTY = No.
- Output: The calculator status is Permitted.
- Interpretation: The TI-84 Plus series is one of the most popular and widely approved graphing calculators for the ACT. It has no prohibited features.
Example 2: A Prohibited Calculator
Another student has a TI-Nspire CAS and needs to know if they can use it.
- Inputs: Brand = Texas Instruments, Model = Nspire CAS, CAS = Yes, QWERTY = No.
- Output: The calculator status is Prohibited.
- Interpretation: Even though the non-CAS version of the TI-Nspire is allowed, the presence of a Computer Algebra System (CAS) makes this specific model explicitly forbidden. This highlights how crucial the exact model name is when asking “can you use calculator on act“.
How to Use This ACT Calculator Policy Checker
This tool simplifies the official ACT calculator policy. Follow these steps to check your device:
- Select Brand: Choose your calculator’s brand from the dropdown list. If it’s not listed, select “Other”.
- Enter Model: Type the model number into the text field. You can usually find this on the front of the calculator (e.g., “TI-84 Plus CE”, “fx-9750GII”).
- Answer Feature Questions: Check the boxes if your calculator has a Computer Algebra System (CAS) or a QWERTY keyboard.
- Read the Results: The tool will instantly display one of three statuses:
- Permitted: You’re good to go! Your calculator is allowed.
- Prohibited: You cannot use this calculator on the ACT.
- Review/Modification Needed: Your calculator may have features that need to be disabled or removed (like sound or paper tape). The “Reasoning” will provide details.
Using this tool to confirm whether you can use your calculator on the ACT beforehand prevents stress and potential issues on test day.
Key Factors That Affect ACT Calculator Eligibility
Several key factors determine if a calculator is approved for the ACT. Familiarizing yourself with these can help you avoid surprises. The question of if you can use a calculator on the ACT often comes down to these six points.
- Computer Algebra System (CAS): This is the most common reason for a calculator to be banned. CAS functionality allows a calculator to perform symbolic algebra, which undermines the purpose of the Math test.
- QWERTY Keyboards: Any calculator with a typewriter-style keyboard is prohibited to prevent students from typing and storing notes.
- Communication Components: Devices with infrared ports, Wi-Fi, or Bluetooth are banned to prevent cheating. Some older models with infrared ports are allowed if the port is completely covered with opaque tape.
- External Devices or Power: Calculators needing an electrical outlet, or those that are part of a phone, tablet, or laptop, are strictly forbidden.
- Noise and Printing: Calculators that make noise must be muted, and those with paper tape must have the tape removed before the test begins.
- Stored Programs/Documents: Even on a permitted calculator like a TI-84, you must remove all programs that have CAS functionality and any stored documents or notes.
Frequently Asked Questions (FAQ)
1. Can you use a calculator on all sections of the ACT?
No, calculators are only permitted during the Mathematics section. Using one on the English, Reading, or Science sections is prohibited.
2. What happens if I bring a prohibited calculator to the test?
Testing staff will not permit you to use it. If you are found using one during the test, you may be dismissed and have your score voided. It is your responsibility to know if you can use your calculator on the ACT.
3. Is the TI-84 Plus approved for the ACT?
Yes, all versions of the TI-84 Plus, including the Plus CE and Python editions, are approved for the ACT. It’s one of the most recommended calculators.
4. Are scientific calculators allowed?
Yes, all standard scientific calculators are allowed and are a great choice for students who don’t need graphing functions.
5. Do I have to clear the memory on my calculator?
You must remove any programs that have CAS functionality, as well as any stored notes or documents. While a full memory clear is the easiest way to ensure compliance, it’s not strictly required if you manually remove prohibited items.
6. Can I use a calculator app on my phone or watch?
No. All phones, smartwatches, tablets, and laptops are strictly forbidden for use as a calculator.
7. What is the difference between a TI-Nspire and a TI-Nspire CAS?
The TI-Nspire (non-CAS) is a permitted graphing calculator. The TI-Nspire CAS has a Computer Algebra System, making it prohibited. This is a key distinction for anyone asking “can you use a calculator on the ACT“.
8. Can I share my calculator with another student?
No, sharing calculators during the test is not permitted under any circumstances.
