What is ACT Calculators Allowed Policy?
The act calculators allowed policy is a specific set of rules established by ACT, Inc. to ensure a level playing field for all test-takers. This policy determines which electronic devices can be used during the Mathematics portion of the exam. Understanding act calculators allowed criteria is vital because using a prohibited device can lead to immediate dismissal and the cancellation of your test scores.
Students should use this guide to verify their TI, Casio, or HP devices well before test day. Common misconceptions include the belief that all graphing calculators are banned; in reality, most standard graphing calculators like the TI-84 are act calculators allowed, provided they do not feature Computer Algebra Systems (CAS).
act calculators allowed Formula and Mathematical Logic
While not a traditional math formula, the act calculators allowed logic follows a strict Boolean derivation. If any prohibitive variable is true, the result is “Prohibited.”
| Variable | Requirement | Unit/Type | Allowed Range |
|---|---|---|---|
| CAS (Symbolic) | No Algebra Engine | Boolean | False |
| Keyboard | Non-QWERTY | Layout | ABC / Numeric |
| Connectivity | Standalone | Radio/Port | Offline Only |
| Display | Standard Screen | Media | No Photos/Video |
Practical Examples (Real-World Use Cases)
Example 1: The TI-84 Plus CE. A student brings a TI-84 Plus CE to the exam. Inputs: CAS=No, Keyboard=Numeric, Connectivity=Disabled. Output: act calculators allowed. Interpretation: This is the most popular choice and is fully compliant because it lacks a CAS engine.
Example 2: The TI-89 Titanium. A student attempts to use a TI-89. Inputs: CAS=Yes, Keyboard=Numeric, Connectivity=Disabled. Output: Prohibited. Interpretation: Despite having a standard keyboard, the TI-89 has a Computer Algebra System that can solve complex equations automatically, violating the act calculators allowed core rules.
How to Use This act calculators allowed Calculator
1. Identify your calculator model brand and series using the first dropdown menu.
2. Select whether your device features a “CAS” (Computer Algebra System). Check the physical casing; if it says “CAS,” it is likely prohibited under act calculators allowed rules.
3. Verify the keyboard layout. Ensure it is not a standard computer QWERTY layout.
4. Check for external features like wireless capability or a requirement for a power outlet.
5. Review the act calculators allowed status. If it says “Prohibited,” you must find a different device for test day.
Key Factors That Affect act calculators allowed Results
- CAS Functionality: This is the number one reason devices fail act calculators allowed checks. Systems that solve for variables (X+Y) symbolically are banned.
- Keyboard Configuration: QWERTY keyboards are viewed as data-entry tools, which are prohibited to prevent cheating or storage of long notes.
- Wireless Communication: Infrared, Bluetooth, and Wi-Fi are strictly prohibited to ensure students cannot communicate or access the internet.
- Display and Media: Any device capable of displaying photos or video is not considered one of the act calculators allowed.
- Power Requirements: You cannot plug your calculator into a wall outlet; it must be battery-operated (rechargeable internal batteries are okay if charged).
- Model Evolution: Newer versions of old models (like the TI-Nspire CAS vs TI-Nspire CX) have different statuses. Always check the exact suffix.
Frequently Asked Questions (FAQ)
Is the TI-Nspire CX II allowed?
Yes, the TI-Nspire CX II is part of the act calculators allowed list, but the TI-Nspire CX II CAS is prohibited.
Can I use a calculator with a touch screen?
Yes, touch screens are generally allowed as long as the device does not have CAS or a QWERTY keyboard.
Do I have to clear my memory?
ACT does not strictly require clearing memory, but they suggest it. Proctors may check for stored programs that mimic prohibited features.
What happens if I bring a prohibited calculator?
If you use a device that is not on the act calculators allowed list, you will be dismissed and your test will not be scored.
Can I share a calculator with a friend?
No, you cannot share calculators during the exam. Each student must have their own act calculators allowed device.
Is the Casio Prizm allowed?
Yes, the Casio FX-CG10 and FX-CG50 (Prizm) series are act calculators allowed.
Are “Watch” calculators allowed?
No, any calculator built into a watch or mobile phone is strictly prohibited under the act calculators allowed policy.
Can I bring a backup calculator?
Yes, but only one calculator can be on your desk at a time. Both must be act calculators allowed models.
