ACT Calculator Policy Checker
An essential tool to determine if your calculator meets the official act calculator policy for test day.
Is Your Calculator Approved?
Enter your calculator model and check its features below to see if it’s allowed on the ACT test. The act calculator policy is strict, so confirming compliance is a critical step in your test preparation.
Entering your model helps with the summary, but the feature checklist below determines the result.
Select any features your calculator has. According to the act calculator policy, any of these will likely result in it being prohibited.
What is the ACT Calculator Policy?
The act calculator policy is a set of rules established by ACT, Inc. to ensure fairness and test security during the mathematics portion of the ACT test. While students are encouraged to use a familiar calculator, the policy explicitly prohibits devices with features that could provide an unfair advantage. All problems on the ACT can be solved without a calculator, but using an approved one efficiently can save valuable time. The responsibility falls on the student to bring a working, approved calculator. Test center staff will not provide them.
The ACT Calculator Policy Formula and Explanation
The “formula” for determining if a calculator is allowed isn’t mathematical but logical. It’s a series of checks against a list of prohibited features. The core principle of the act calculator policy is to ban any device that can perform symbolic algebraic manipulation (via a Computer Algebra System) or that can communicate with other devices. Our calculator uses this exact logic.
| Variable (Feature) | Meaning | Unit / Type | Test Day Status |
|---|---|---|---|
| Computer Algebra System (CAS) | Can solve algebraic equations symbolically. | Boolean | Prohibited |
| QWERTY Keyboard | A typewriter-style keyboard layout. | Boolean | Prohibited |
| Wireless Capability | Includes Wi-Fi, Bluetooth, or infrared ports. | Boolean | Prohibited (or must be covered) |
| External Power Requirement | Must be plugged into an outlet to function. | Boolean | Prohibited |
| Integrated Device | Part of a phone, tablet, or computer. | Boolean | Prohibited |
Practical Examples
Example 1: A Prohibited Calculator
A student wants to bring a TI-89 Titanium. Here are the inputs and results:
- Inputs: Calculator Model = “TI-89 Titanium”, “Computer Algebra System (CAS)” checkbox = checked.
- Reasoning: The TI-89 is explicitly banned because it contains a CAS, which violates the act calculator policy.
- Result: PROHIBITED
Example 2: A Permitted Calculator
A student wants to bring a TI-84 Plus CE. Check out this guide on {related_keywords} for more tips.
- Inputs: Calculator Model = “TI-84 Plus CE”, No prohibited features are checked.
- Reasoning: The TI-84 Plus series does not have a CAS, a QWERTY keyboard, or other banned features. It is one of the most common {related_keywords}.
- Result: PERMITTED
How to Use This ACT Calculator Policy Calculator
- Enter Your Model (Optional): Type your calculator’s model name. This helps identify it in the results summary.
- Check for Prohibited Features: Carefully review the checklist. If your calculator has any of these features (like a CAS or QWERTY keyboard), check the corresponding box.
- Analyze the Result: The tool will immediately display “PERMITTED” or “PROHIBITED”.
- Read the Reason: The output explains *why* your calculator is or isn’t allowed, based on the act calculator policy. This is crucial for your understanding.
- Reset if Needed: Use the “Reset” button to clear the form and check another calculator.
Key Factors That Affect the ACT Calculator Policy
The policy is designed to prevent cheating and ensure a level playing field. Understanding the factors that lead to a calculator being banned is key to achieving a great {related_keywords}.
- Computer Algebra System (CAS): This is the most significant factor. CAS can solve ‘x’ in algebraic equations, which the ACT requires students to do manually.
- Communication Ability: Any feature that allows communication (Bluetooth, Wi-Fi, infrared) is banned to prevent sharing answers.
- QWERTY Keypads: Calculators with typewriter-style keyboards are prohibited as they could be used to store notes.
- Device Integration: You cannot use the calculator on your phone, tablet, or laptop.
- Power Source: The calculator must be battery-powered. Devices that need an external power cord are not allowed.
- Noise and Printing: Calculators that make noise or have a paper tape must have these features disabled or removed. For more on test day rules, see our {related_keywords} guide.
Frequently Asked Questions (FAQ)
1. Can I use a graphing calculator on the ACT?
Yes, most graphing calculators are allowed, as long as they are not on the prohibited list. Popular permitted models include the TI-83, TI-84, and the non-CAS version of the TI-Nspire.
2. What is a Computer Algebra System (CAS)?
A CAS is a sophisticated program that can manipulate mathematical expressions in a symbolic way, much like a person would on paper. For example, it can solve for ‘x’ in ‘2x + 5 = 15’ instead of just crunching numbers. This is forbidden by the act calculator policy.
3. What if my calculator is not on the prohibited list but has a banned feature?
If it has a prohibited feature, like a QWERTY keyboard, it is not allowed, even if the specific model isn’t listed. The features are the deciding factor.
4. Do I have to clear my calculator’s memory?
The ACT requires you to remove any programs that have CAS functionality. While a full memory clear is the safest bet, the primary concern is removing prohibited programs. Stored numbers or simple programs are generally fine.
5. Can I use the calculator on my smartphone?
No. All phones, tablets, smartwatches, and laptops are strictly prohibited for use as a calculator.
6. What happens if I bring a prohibited calculator?
Testing staff will confiscate the calculator, and you may be dismissed from the test center and have your scores voided.
7. What is the difference between the TI-Nspire CAS and the regular TI-Nspire?
The TI-Nspire CAS is prohibited because it has a Computer Algebra System. The standard TI-Nspire (non-CAS) is permitted because it lacks this specific functionality. It’s crucial to check for the “CAS” designation on the calculator itself. Get ready for the exam with our {related_keywords} resources.
8. Are there any modifications that can make a prohibited calculator allowed?
In some limited cases, yes. For example, calculators with paper tape must have the tape removed. Those with infrared ports must have them covered with opaque tape. However, a feature like CAS cannot be “modified” away, so the calculator remains prohibited.
