What is the ACT Calculator Policy?
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 specifies which features are prohibited to prevent any student from having an unfair advantage. The rules target calculators with advanced communication features, computer algebra systems (CAS), or QWERTY keyboards.
This policy is for any student taking the ACT who plans to use a calculator. All problems on the ACT Math test can be solved without a calculator, but using a familiar and permitted device is highly encouraged for efficiency. A common misconception is that all graphing calculators are banned, which is untrue; many popular models like the TI-84 Plus series are perfectly acceptable. Understanding the specifics of the ACT calculator policy is a key part of test preparation.
The ACT Calculator Rules: A Formula for Acceptance
Think of the ACT calculator policy as a logical formula. A calculator is deemed “PROHIBITED” if it has one or more forbidden features. The core principle is that the calculator should be a tool for calculation, not for storing information, communicating, or solving algebraic equations symbolically.
The step-by-step logic is as follows:
- Check for CAS: Does the calculator have a Computer Algebra System? If yes, it’s prohibited.
- Check for Keyboard: Does it have a QWERTY-style keyboard? If yes, it’s prohibited.
- Check for Communication: Does it have wireless, Bluetooth, or infrared capabilities? If yes, it’s prohibited (or the port must be covered).
- Check for Device Type: Is it a phone, tablet, or laptop? If yes, it is strictly prohibited.
If the answer to all these questions is “No,” the calculator is generally permitted.
Variables of the Policy
| Variable | Meaning | Status if Present | Typical Range/Examples |
|---|---|---|---|
| CAS | Computer Algebra System | Prohibited | TI-Nspire CAS, HP Prime, TI-89 |
| QWERTY | Typewriter-style Keyboard | Prohibited | Older models with full keyboards |
| Wireless | Wi-Fi, Bluetooth, Cellular | Prohibited | Not applicable to standard calculators |
| External Device | Phone, Tablet, Laptop | Prohibited | Any smart device with a calculator app |
| Graphing | Ability to plot functions | Allowed | TI-84 Plus, Casio fx-9750GII |
Practical Examples of ACT Calculator Rulings
Let’s apply the ACT calculator policy to real-world scenarios.
Example 1: The TI-84 Plus CE
- Inputs: No QWERTY keyboard, no CAS, no wireless.
- Analysis: This popular graphing calculator is fully compliant with the ACT calculator policy because it lacks any prohibited features.
- Output: ALLOWED. It is one of the most recommended calculators for the test.
Example 2: The TI-Nspire CAS CX II
- Inputs: Has a Computer Algebra System (CAS).
- Analysis: The presence of a CAS, which can solve algebraic equations symbolically, is a direct violation of the policy. Even though its non-CAS counterpart is allowed, this specific model is not.
- Output: PROHIBITED. Bringing this calculator to the test would result in it being confiscated.
How to Use This ACT Calculator Policy Checker
Using this tool is straightforward and provides instant feedback on the ACT calculator policy.
- Enter Model (Optional): Type your calculator’s model name into the first field. Our tool checks it against a list of known prohibited models like the TI-89.
- Check Prohibited Features: For each question, check the box if your calculator has that specific feature. Be honest—this is to help you prepare.
- Read the Result: The large-print result at the top will immediately change to “ALLOWED” or “PROHIBITED” based on your inputs.
- Review the Reasons: Below the main result, the tool will list exactly which rules were violated.
- Analyze the Chart: The bar chart provides a quick visual reference for which prohibited features you’ve selected.
Making a decision is simple: if the result is PROHIBITED, do not bring that calculator. You will need to find a different, compliant calculator for the test. For more help, check out this guide on list of approved ACT calculators.
Key Factors That Affect Calculator Permissibility
Several key factors determine whether a calculator is allowed. Understanding these will help you comply with the ACT calculator policy.
- Computer Algebra System (CAS): This is the most common reason for a calculator to be banned. CAS can perform algebraic manipulations, which is considered an unfair advantage.
- QWERTY Keyboards: Any calculator with a keyboard layout like a computer (QWERTY) is forbidden.
- Communication Technology: Devices that can connect to the internet, other devices via Bluetooth, or have infrared ports are prohibited. Some older models with infrared ports are allowed only if the port is completely covered with opaque tape.
- External Power Source: Calculators that need to be plugged into a wall are not allowed.
- Noise and Printing: Calculators that make noise must be muted, and those with paper tape must have the tape removed.
- Programs and Documents: Even on an allowed calculator like a TI-84, you must remove any stored programs or documents. Proctors may inspect your calculator’s memory.
Frequently Asked Questions (FAQ)
1. Can I use a calculator on all sections of the ACT?
No, calculators are only permitted during the Mathematics section. They are not allowed on the English, Reading, or Science sections. Exploring effective ACT math strategies can help you use your calculator wisely.
2. What happens if I bring a prohibited calculator?
Testing staff will confiscate the calculator, and you may be dismissed from the test. Your score for that test date could be voided. It is your responsibility to know the ACT calculator policy.
3. Is the TI-Nspire allowed?
It depends. The TI-Nspire (non-CAS) model is allowed. However, the TI-Nspire CAS model is strictly prohibited. You must check your specific model.
4. Do I have to clear the memory on my calculator?
Yes, it is highly recommended. The policy forbids storing programs that have computer algebra system functionality. To be safe, clear all programs and stored documents before the test. To understand what’s at stake, see our article about what is a good score on the ACT.
5. Will the test center provide a calculator?
No, you are responsible for bringing your own approved calculator. Test centers do not provide them.
6. I saw ‘can we use calculator in act yahoo’ in a search. What does Yahoo have to do with it?
Absolutely nothing. This is a quirk of how search engines like Google and Bing combine popular search terms. “Can we use a calculator on the ACT” is a common question, and “Yahoo” is a popular website. The search engine simply mashed them together. The official ACT calculator policy is set by ACT, Inc. and has no connection to Yahoo.
7. What’s a better choice: a scientific or graphing calculator?
This depends on your comfort level. Both are allowed. A graphing calculator can be powerful if you know how to use it, but a scientific calculator is often faster for basic calculations. The important thing is to practice with the calculator you plan to use. This choice is part of a good how to study for the ACT plan.
8. Is the policy different for the SAT?
Yes, the policies are similar but have slight differences. You should always check the specific policy for the test you are taking. Our SAT vs ACT comparison guide can offer more insights.
