ACT Calculator Policy Checker
A quick and easy way to determine if you can use a calculator on the ACT.
Is Your Calculator Allowed?
Check your calculator’s features against the official ACT rules. This tool will help you determine if your device is permitted on test day.
Enter your model to check against the specifically prohibited list.
Understanding the ACT Calculator Policy
What does it mean to ask ‘can you use a calculator on the act’?
The question “can you use a calculator on the ACT” is a common one for students preparing for the exam. The simple answer is yes, but with significant restrictions. The ACT allows calculators only on the Mathematics section, and not all calculators are permitted. The policy is in place to ensure fairness and prevent any student from having an unfair advantage through technology. Understanding these rules before test day is critical to avoid having your calculator confiscated or, in worst-case scenarios, your test being invalidated.
How to Determine if Your Calculator is Allowed
The ACT’s “formula” for determining if a calculator is allowed is a set of rules based on its features and model number. A calculator is prohibited if it has features that can give a student an unfair advantage, such as solving algebraic equations symbolically or accessing the internet. The calculator above helps you apply these rules to your device.
| Variable / Feature | Meaning | ACT Policy Status |
|---|---|---|
| Computer Algebra System (CAS) | The ability to solve algebraic equations and manipulate variables symbolically (e.g., solve for x). | Prohibited |
| QWERTY Keyboard | A letter-key layout like a computer or smartphone. | Prohibited |
| Wireless Communication | Any feature like Bluetooth, Wi-Fi, or infrared ports. | Prohibited (or requires port to be covered) |
| External Power Requirement | A device that must be plugged into a wall outlet to work. | Prohibited |
| Part of Phone/Laptop | Using the calculator function on a smartphone, tablet, or computer. | Prohibited |
Practical Examples
Example 1: A Permitted Calculator
A student has a TI-84 Plus CE. They use the checker above, leaving all boxes unchecked. The model is not on the prohibited list. The result is “Permitted.” This is a standard graphing calculator without CAS functionality and is one of the most common calculators used for the ACT.
Example 2: A Prohibited Calculator
Another student has a TI-Nspire CX CAS. They check the “Computer Algebra System (CAS)” box. The result is immediately “Prohibited.” Even though it looks similar to other graphing calculators, its CAS functionality is explicitly banned by the ACT to ensure students solve algebra problems themselves.
How to Use This ‘can you use a calculator on the act’ Calculator
This tool simplifies the official ACT policy into a few easy steps:
- Enter Model (Optional): Type your calculator’s model name (e.g., TI-84 Plus, Casio fx-9750GII) into the first field. This helps check it against a list of specifically banned models.
- Check Prohibited Features: Read through the list of features and check the box next to any that your calculator has. Be honest—it’s better to find out now than on test day.
- Check Status: Click the “Check Status” button.
- Interpret the Results: The tool will give you a clear “Permitted” or “Prohibited” status and explain the reasoning based on your input.
Key Factors That Affect if You Can Use a Calculator on the ACT
- Computer Algebra System (CAS): This is the most common reason a graphing calculator is banned. CAS can perform symbolic algebra, which is against the rules.
- Specific Model Number: The ACT explicitly prohibits all models that start with TI-89 or TI-92, as well as the HP Prime and others.
- QWERTY Keypad: Calculators with a full keyboard are not allowed as they make it easier to type and store text.
- Communication Ability: Any device that can communicate wirelessly (Bluetooth, infrared) is prohibited.
- Power Source: Your calculator must be battery-powered. Devices that need to be plugged in are not allowed.
- Noise: Calculators that make noise must have the sound feature turned off.
Frequently Asked Questions (FAQ)
1. Can I use a TI-84 Plus on the ACT?
Yes, all versions of the TI-84 Plus (including the CE) are permitted as they do not have a Computer Algebra System (CAS).
2. What is a Computer Algebra System (CAS)?
A CAS is a feature that allows a calculator to manipulate mathematical expressions symbolically. For example, it can solve an equation like ‘3x – 9 = 0’ and provide the answer ‘x = 3’. This functionality is banned on the ACT.
3. What if my calculator is not on the prohibited list but has a banned feature?
If your calculator has a banned feature, like a QWERTY keyboard, it is prohibited even if the model name isn’t explicitly listed. The feature rules are the most important part of the policy.
4. Do I need to clear my calculator’s memory?
The ACT requires you to remove any programs that have computer algebra system functionality. It’s a good practice to clear any non-essential programs and data before the test.
5. Can I use my smartphone as a calculator?
No. All cell phones, tablets, smartwatches, and laptops are strictly prohibited from being used during the test.
6. What happens if I’m caught with a prohibited calculator?
The testing staff will likely confiscate the calculator, and you may be dismissed from the test center, and your test score will be voided.
7. Can I use a scientific calculator?
Yes, most standard scientific calculators (like the TI-30X series) are allowed. They are often a great choice as they are powerful enough for the ACT math section without the risk of being prohibited.
8. Where can I find the official policy?
The most up-to-date policy is always available on the official ACT website. You should always double-check the policy there before your test date.
