Understanding the ACT Calculator Policy
What are ACT Approved Calculators?
ACT approved calculators are specific handheld devices that students are permitted to use during the mathematics section of the ACT test. The ACT organization sets a detailed policy to ensure fairness, prevent academic dishonesty, and maintain a standardized testing environment. While most basic, scientific, and graphing calculators are allowed, there are critical exceptions and rules regarding prohibited features and models. Understanding the list of ACT approved calculators is crucial for any student preparing for the exam.
This policy is for all students taking the ACT who wish to use a calculator on the math test. Misunderstanding the rules can lead to a student being forced to take the test without a familiar tool or, in worst-case scenarios, dismissal from the test. A common misconception is that any graphing calculator is acceptable. However, models with a Computer Algebra System (CAS) are strictly forbidden, making it vital to check your specific model against the ACT’s official list of prohibited devices. Using our checker for ACT approved calculators can save you from a stressful test-day surprise.
ACT Calculator Policy and Rules Explanation
Unlike a mathematical formula, the policy for ACT approved calculators is a set of rules. The general rule is: any 4-function, scientific, or graphing calculator is allowed, as long as it is NOT on the prohibited list and is modified if required. The policy focuses on prohibiting devices that give an unfair advantage.
The core of the policy is the prohibited list. This list primarily targets calculators with advanced functionality like a Computer Algebra System (CAS), which can solve algebraic equations symbolically. Other banned features include wireless communication, QWERTY keyboards, and stylus input.
| Rule Category | Description | Status | Example |
|---|---|---|---|
| General Use | 4-function, scientific, and graphing calculators. | Permitted | TI-84 Plus, Casio fx-9750GII |
| Prohibited: CAS | Calculators with a Computer Algebra System (CAS). | Prohibited | TI-89, TI-Nspire CAS, HP Prime |
| Prohibited: QWERTY | Calculators with a typewriter-style (QWERTY) keyboard. | Prohibited | Older models with text input |
| Prohibited: Communication | Devices with wireless, Bluetooth, or internet access. | Prohibited | Smartphones, tablets, laptops |
| Modification: Noise | Calculators that make sounds. | Modification Required | Must turn off the sound feature. |
| Modification: Infrared Port | Calculators with an infrared data port. | Modification Required | Cover port with opaque tape (e.g., HP 38G/39G/48G series). |
Practical Examples (Real-World Use Cases)
Example 1: Checking a Prohibited Calculator
- Student’s Calculator: Texas Instruments TI-89 Titanium
- Checking Process: The student enters “TI-89 Titanium” into the ACT approved calculators checker. The system identifies “TI-89” as a root model name that is on the explicit prohibited list.
- Result: PROHIBITED. The tool explains that all calculators beginning with “TI-89” or “TI-92” are banned because they contain a Computer Algebra System (CAS). The student knows they must acquire a different calculator for the test.
Example 2: Checking an Approved Calculator
- Student’s Calculator: Casio fx-9750GII
- Checking Process: The student enters “Casio fx-9750GII”. The system checks this model against the prohibited and conditional lists. It is not found on either.
- Result: APPROVED. The tool confirms that this model does not have prohibited features like CAS and is one of the standard ACT approved calculators. The student can confidently bring it to the test.
How to Use This ACT Approved Calculators Calculator
This tool simplifies the process of verifying your device against the official ACT policy.
- Enter Model Name: Type the model name of your calculator (e.g., “TI-84 Plus”) into the input field. Be as specific as possible.
- Review the Result: The tool will instantly provide one of three statuses: Approved, Prohibited, or Conditional.
- Read the Details: The “Result Details” section explains why your calculator received that status and what action, if any, is required. For example, a conditional status might require you to cover an infrared port.
- Reset if Needed: Use the “Reset” button to clear the fields and check another model. This is helpful for comparing different ACT approved calculators.
Key Factors That Affect ACT Approved Calculators
Choosing from the many ACT approved calculators involves more than just picking one that’s allowed. Here are key factors to consider:
- 1. CAS Functionality: This is the most important factor. Any calculator with a Computer Algebra System is banned. Always verify your model is non-CAS.
- 2. Familiarity: The best calculator is one you know how to use. Don’t buy a complex new graphing calculator the week before the test. Practice with your chosen device for months.
- 3. Graphing vs. Scientific: A graphing calculator can be powerful for visualizing functions, but a scientific calculator is often faster for direct calculations. If you’re comfortable with graphing, it can be an advantage. Many successful students use a high-end scientific calculator.
- 4. Battery Life: A dead calculator is as bad as a prohibited one. Ensure your device has fresh batteries or is fully charged. Bring a backup if you’re concerned.
- 5. Physical Condition: Make sure your calculator doesn’t have features that require modification, like a paper tape that needs to be removed or a sound that needs to be muted.
- 6. Test Day Rules: Remember that even with ACT approved calculators, you cannot share them, and they are only allowed during the math portion of the exam.
Frequently Asked Questions (FAQ)
1. Is the TI-84 Plus CE one of the ACT approved calculators?
Yes, the TI-84 Plus CE is one of the most popular and widely accepted ACT approved calculators. It does not have a CAS.
2. What happens if I bring a prohibited calculator to the test?
The test proctor will not allow you to use it. You will either have to take the math section without a calculator or, if you are caught using it, you may be dismissed and your score canceled.
3. Why is the TI-Nspire CAS banned but the regular TI-Nspire is not?
The “CAS” stands for Computer Algebra System, which is the specific feature the ACT prohibits. The non-CAS version lacks this symbolic algebra functionality and is therefore allowed.
4. Can I use my smartphone’s calculator app?
No. All smartphones, tablets, smartwatches, and laptops are strictly prohibited from use during the test for any reason.
5. Do I need to clear the memory on my calculator?
The ACT policy states you must remove any programs that have computer algebra system functionality. While proctors may not check every calculator, it is your responsibility to ensure it complies. Clearing programs is the safest approach.
6. Is the calculator policy the same for the SAT?
No, the policies are similar but not identical. The SAT has its own list of approved calculators. You should always check the specific policy for the test you are taking. Our SAT calculator policy guide has more info.
7. What’s a good, affordable calculator for the ACT?
Scientific calculators like the TI-30XS MultiView are excellent, affordable options that are more than sufficient for the ACT. They are easy to use and fully compliant.
8. Do test centers provide ACT approved calculators?
No, you are responsible for bringing your own permitted calculator. None will be provided for you.
