ACT Calculator Policy Checker
Is Your Calculator Allowed on the ACT?
Enter your calculator’s model and features to get a preliminary check against the ACT’s calculator policy. Always double-check the official ACT website for the most current rules and specific model restrictions for your test date.
Has a QWERTY (computer-style) keyboard?
Uses paper tape?
Makes noise or “talks”?
Needs an electrical outlet to function?
Has wireless, Bluetooth, or infrared communication?
Has Computer Algebra System (CAS) functionality? (e.g., solves algebraic equations symbolically)
What is the ACT Calculator Policy?
The ACT calculator policy outlines which calculators are permitted and which are prohibited during the ACT test, specifically the Mathematics section. The policy aims to ensure fairness and prevent students from having an unfair advantage through the use of overly sophisticated or unauthorized devices. While most graphing calculators are allowed, some with specific features or capabilities, particularly Computer Algebra Systems (CAS), are banned or restricted. Understanding the ACT calculator policy is crucial before test day.
Students should use this policy to verify their calculator is acceptable. Using a prohibited calculator can lead to dismissal from the test and cancellation of scores. Common misconceptions are that all graphing calculators are fine, or that if it was allowed on the SAT, it’s allowed on the ACT – this is not always the case. Always check the latest ACT calculator policy on the official ACT website.
ACT Calculator Rules and Prohibitions
The ACT does not have a “formula” for calculator allowance but a set of rules and lists. Here’s a breakdown:
Prohibited Features:
- Calculators with built-in or downloaded Computer Algebra Systems (CAS) are generally prohibited (though some exceptions exist if CAS is disabled, always check specific models).
- QWERTY (typewriter-like) keypads.
- Calculators that use paper tape, make noise, or “talk”.
- Calculators requiring an electrical outlet.
- Devices with wireless, Bluetooth, cellular, or infrared communication capabilities.
- Pocket organizers, handheld or laptop computers, and electronic writing pads or pen-input devices.
Specifically Prohibited Models (Examples – always check the current official list):
- Texas Instruments: All TI-89 and TI-92 models, TI-Nspire CAS (non-CAS Nspire may be allowed).
- Hewlett-Packard: HP 48GII, HP 49G, HP 50G, HP Prime.
- Casio: Algebra fx 2.0, ClassPad 300, ClassPad 330, and other CAS models.
Generally Permitted Calculators:
Most standard graphing calculators (like TI-83, TI-84 family, Casio fx-9750GII/GIII, Casio Prizm non-CAS) are allowed, as are scientific and basic four-function calculators, provided they don’t have prohibited features.
Prohibited Features Overview
| Feature/Capability | Reason for Prohibition | Typical Status |
|---|---|---|
| Computer Algebra System (CAS) | Can solve algebraic equations symbolically, giving an unfair advantage. | Prohibited (with few exceptions if disabled) |
| QWERTY Keyboard | Resembles a computer, potential for storing notes. | Prohibited |
| Wireless/Communication | Risk of external communication during the test. | Prohibited |
| Paper Tape/Noise | Distracting to other test-takers. | Prohibited |
| Needs External Power | Not practical in a testing environment. | Prohibited |
Practical Examples (Real-World Use Cases)
Example 1: TI-84 Plus CE
A student has a Texas Instruments TI-84 Plus CE. This model does NOT have CAS and is generally allowed on the ACT. Our checker would likely indicate “Allowed” as long as no prohibited features are checked and the model isn’t on a specific ban list for that year.
Example 2: TI-89 Titanium
A student has a Texas Instruments TI-89 Titanium. This calculator has a built-in CAS. It is explicitly prohibited by the ACT. Our checker would flag this as “Prohibited”.
Example 3: Casio Prizm fx-CG50 vs. fx-CG500
A student has a Casio Prizm. The fx-CG50 is generally allowed as it’s non-CAS. However, the fx-CG500 (or similar ClassPad models) often have CAS and are prohibited. The student needs to be very careful about the exact model number when checking the ACT calculator policy.
How to Use This ACT Calculator Policy Checker
- Enter Model: Type your calculator’s model name/number into the “Calculator Model” field. Be as specific as possible.
- Check Features: Mark the checkboxes for any features your calculator possesses that are listed. Be honest about CAS functionality.
- View Results: The “Primary Result” will give a preliminary indication: “Allowed,” “Prohibited,” or “Check Official List.” “Intermediate Results” will explain why.
- Check Official List: Regardless of the tool’s output, ALWAYS visit the official ACT website (www.act.org) to view the most up-to-date and definitive ACT calculator policy and the list of prohibited calculators for your test date. Policies can change.
- Reset: Use the “Reset” button to clear the fields and start over.
This tool provides guidance based on general rules and common models but is not a substitute for the official ACT policy.
Key Factors That Affect ACT Calculator Allowance
- Computer Algebra System (CAS): This is the most significant factor. Calculators that can perform symbolic algebra (manipulating variables and expressions) are usually banned.
- Specific Model Number: The ACT often lists specific models that are prohibited, even if they are similar to allowed ones.
- QWERTY Keypad: Any calculator with a typewriter-style keyboard is not allowed.
- Communication Features: Calculators with infrared, Bluetooth, or any wireless communication are banned.
- Power Source: Calculators needing an external power source are not permitted.
- Noise/Tape: Anything that makes noise or uses paper tape is prohibited to avoid disturbing others.
- Test Date Policy: The ACT can update its policy, so check the rules for your specific test date. What was allowed last year might not be this year.
Frequently Asked Questions (FAQ) about the ACT Calculator Policy
- Can I use a TI-84 Plus on the ACT?
- Yes, the TI-84 Plus family (including Plus, Silver Edition, C Silver Edition, CE) is generally permitted as it does not have CAS.
- Is the TI-Nspire allowed on the ACT?
- The TI-Nspire CX (non-CAS) is usually allowed, but the TI-Nspire CX CAS is prohibited. You must know which version you have.
- What if my calculator has CAS but it can be disabled?
- The ACT policy generally prohibits calculators with built-in CAS, even if it can be disabled. However, there have been exceptions or specific instructions for certain models in the past (like some TI-Nspire non-CAS models that can have CAS installed). Always check the official ACT list for your test date regarding models with disable-able CAS.
- What happens if I bring a prohibited calculator?
- If you are found using a prohibited calculator, you will likely be dismissed from the test, and your scores will be canceled. It’s not worth the risk.
- Can I use my phone’s calculator app?
- No, cell phones and any devices with communication capabilities are strictly prohibited during the test.
- Are scientific calculators allowed?
- Yes, most scientific calculators are allowed as long as they don’t have prohibited features.
- Do I need a graphing calculator for the ACT?
- While not strictly required (a scientific calculator can be used), a graphing calculator can be very helpful for certain problems, especially if you are familiar with its functions. Ensure you are comfortable with whichever calculator you bring and that it complies with the ACT calculator policy.
- Where do I find the official ACT calculator policy?
- On the official ACT website (www.act.org). Search for “calculator policy” within their site.
