ACT Calculator Permissibility Checker
Is Your Calculator Allowed on the ACT?
Answer the questions below based on your calculator’s features to see if it’s likely one of the calculators that can be used on the ACT.
How Permissibility is Determined:
The ACT prohibits calculators with certain features. This tool checks your answers against the common prohibited features: Computer Algebra Systems (CAS), QWERTY keyboards, pen/stylus input, noise, wireless communication, need for an outlet, and being part of a multi-purpose device like a phone or laptop. If any of these are present, the calculator is likely prohibited. The final decision rests with the test center staff based on the official ACT calculator policy.
What are Calculators That Can Be Used on the ACT?
Calculators that can be used on the ACT are those that meet the specific requirements outlined in the official ACT calculator policy. The ACT permits most four-function, scientific, or graphing calculators, as long as they do NOT have certain prohibited features. The policy aims to ensure fairness and prevent access to unauthorized information or capabilities during the test.
Students taking the ACT, particularly the mathematics section, should use one of the permitted calculators that can be used on the ACT to help with speed and accuracy on arithmetic, algebraic, and geometric calculations. However, it’s crucial to be familiar with your calculator’s functions *before* the test day.
Common misconceptions include believing all graphing calculators are allowed (some with CAS are not) or that any scientific calculator is fine (those with QWERTY keyboards are prohibited). Always check the latest ACT calculator policy on the official ACT website before your test date, as the list of calculators that can be used on the ACT and prohibited features can be updated.
ACT Calculator Policy: Key Rules and Prohibited Features
The ACT has a clear policy regarding which calculators are permitted and which are not. The fundamental rule is that the calculator must not give an unfair advantage. Here’s a breakdown:
- Prohibited Features:
- Computer Algebra Systems (CAS): Calculators that can solve algebraic equations symbolically (e.g., TI-89, TI-Nspire CAS) are not allowed. A TI-Nspire non-CAS is usually okay.
- QWERTY Keyboards: Calculators with typewriter-like keyboards are prohibited.
- Pen-Input or Stylus Devices: No devices requiring a pen or stylus are permitted.
- Communication: Calculators with wireless, Bluetooth, cellular, or internet capabilities are strictly forbidden.
- Noise: Devices that make noise must have the volume turned off (or are not allowed if it cannot be).
- Power Source: Calculators must be battery-operated; those needing an electrical outlet are not allowed.
- Part of Other Devices: You cannot use the calculator function on a phone, tablet, laptop, or any other general-purpose electronic device.
- Paper Tape: Calculators that print to a paper tape are not permitted.
- Permitted Calculators (Generally): Most four-function, scientific, and graphing calculators are allowed if they don’t have the prohibited features listed above. Many TI-83, TI-84, and non-CAS TI-Nspire models are among the calculators that can be used on the ACT.
- Calculators Requiring Modification: Some calculators might be allowed if features like infrared data ports are covered with heavy tape, or memory is cleared.
It is the student’s responsibility to bring an approved calculator. Test center staff will check, and you won’t be allowed to test with a prohibited device.
Examples of Permitted and Prohibited Calculators
| Model Series/Type | Generally Permitted? | Reason/Notes |
|---|---|---|
| TI-83, TI-84 Plus, TI-84 Plus CE | Yes | Most models in this series are fine as they lack CAS and QWERTY. |
| TI-89, TI-92 | No | These have CAS. |
| TI-Nspire CX CAS, CX II CAS | No | CAS versions are prohibited. |
| TI-Nspire CX, CX II (non-CAS) | Yes | Non-CAS versions are generally permitted. |
| Casio fx-9750GII, fx-9860GII | Yes | Generally permitted, lack prohibited features. |
| Casio ClassPad series | No | Often have CAS and/or stylus input. |
| HP Prime | No (with CAS), Yes (exam mode) | The HP Prime has CAS, but an exam mode might be acceptable if properly configured according to ACT’s specific guidelines for that model – check current policy. |
| Calculators on phones/laptops | No | Absolutely prohibited. |
How to Use This ACT Calculator Permissibility Checker
Using this checker is straightforward:
- Examine Your Calculator: Look at your calculator and its manual to identify its features.
- Answer the Questions: For each question about features like CAS, QWERTY keyboard, stylus, noise, wireless, power source, and device type, select “Yes” or “No” from the dropdown menus based on your calculator.
- Check Results: As you select options, the “Permissibility Status” and “Reasons” will update automatically, indicating whether your calculator is “Likely Permitted,” “Likely Not Permitted,” or “Prohibited” based on your answers.
- Enter Model (Optional): You can enter your calculator’s model name to include it in the results you might copy.
- Reset if Needed: Click “Reset” to clear your selections and start over.
- Copy Results: Click “Copy Results” to copy the permissibility status, reasons, and model name (if entered) to your clipboard for your records.
Decision-Making Guidance: If the checker indicates “Likely Not Permitted” or “Prohibited,” you should NOT bring that calculator to the ACT. Find an alternative from the list of calculators that can be used on the ACT and become familiar with it well before the test. If it says “Likely Permitted,” it’s still wise to double-check against the official ACT website’s most recent calculator policy.
Key Factors That Affect ACT Calculator Permissibility
Several factors determine whether a calculator is among the calculators that can be used on the ACT:
- Computer Algebra System (CAS): This is a major disqualifier. CAS can perform symbolic manipulation (like factoring, solving for variables in equations), which goes beyond the numerical calculations ACT allows.
- QWERTY Keyboard: Calculators with full alphabetic keyboards are banned to prevent the storage of notes or formulas disguised as text.
- Communication Features: Any ability to communicate wirelessly (infrared, Bluetooth, Wi-Fi, cellular) is strictly prohibited to prevent cheating or access to external information.
- Pen/Stylus Input: Devices using these are often more like small computers and are not allowed.
- Noise and Power: Calculators shouldn’t be disruptive (noise) or require external power sources.
- Integration with Other Devices: The calculator must be a standalone device, not an app on a phone, tablet, or laptop.
- Official ACT Policy Updates: The ACT organization periodically updates its calculator policy. What was allowed last year might not be this year, so always check the latest rules before your test. Understanding the current list of calculators that can be used on the ACT is vital.
