What are act permitted calculators?
The term act permitted calculators refers to the specific set of electronic calculating devices that the ACT (American College Testing) organization allows students to use during the Mathematics portion of the exam. Because the ACT is a standardized test designed to measure individual mathematical reasoning, certain high-powered features are restricted to ensure academic integrity.
Many students mistakenly believe that any graphing calculator is allowed. However, act permitted calculators must not have “Computer Algebra System” (CAS) functionality. A CAS allows a device to solve complex algebraic equations symbolically, which bypasses the core skills the ACT aims to test. Using a prohibited device can lead to immediate dismissal and voiding of your test scores.
act permitted calculators Logic and Rules
The logic behind whether a device falls under act permitted calculators is binary: if it possesses even one prohibited feature, the entire device is banned. The mathematical evaluation of compliance follows a strict “Zero-Tolerance” derivation.
| Variable | Meaning | Permitted Value | Impact |
|---|---|---|---|
| CAS | Symbolic Algebra Engine | No | Immediate Disqualification |
| COM | Wireless/Cellular/Bluetooth | No | Immediate Disqualification |
| KBD | QWERTY Keyboard | No | Restricted (Prohibited) |
| PWR | Wall Outlet Connection | No | Restricted (Prohibited) |
| TAPE | Paper Printing Component | No | Immediate Disqualification |
Practical Examples of act permitted calculators
Example 1: The TI-84 Plus CE
The TI-84 Plus CE is one of the most popular act permitted calculators. It features a high-resolution color screen and graphing capabilities but lacks a CAS engine and wireless communication.
Input: CAS=No, Wireless=No, Keyboard=Numeric.
Result: 100% Permitted.
Example 2: The TI-Nspire CX II CAS
While the non-CAS version is permitted, the “CAS” version of this model is strictly prohibited under the act permitted calculators policy because it can manipulate variables symbolically.
Input: CAS=Yes, Wireless=No, Keyboard=Numeric.
Result: Prohibited.
How to Use This act permitted calculators Checker
- Identify the specific model of your calculator (check the front casing or the “About” screen in the settings).
- Determine if it has CAS: Look for the letters “CAS” in the model name.
- Check the keyboard: If it looks like a computer keyboard (QWERTY), it is likely prohibited.
- Select the options in our tool above. The act permitted calculators status will update in real-time.
- Read the “Recommendation” to see if modifications (like removing the battery cover or clearing memory) are required.
Key Factors That Affect act permitted calculators Compliance
- Computer Algebra System (CAS): This is the most common reason for a device to be excluded from act permitted calculators. It allows for symbolic manipulation which is forbidden.
- Communication Features: To prevent cheating, any device that can transmit data via infrared, Bluetooth, or Wi-Fi is excluded.
- Input Hardware: Calculators with QWERTY keyboards are viewed as potential note-storage devices and are generally banned.
- Physical Form Factor: If your calculator requires a power cord or has a paper tape printer, it is not an act permitted calculator.
- Sound and Noise: Distracting other test-takers is a violation. Your device must be silent.
- Model Specificity: Even within a brand (like Texas Instruments), one model might be permitted (TI-Nspire CX) while another is banned (TI-Nspire CAS).
Frequently Asked Questions (FAQ)
1. Can I use the TI-89 for the ACT?
No. The TI-89 contains CAS and is never allowed among act permitted calculators.
2. Is the TI-Nspire allowed?
The TI-Nspire (non-CAS) is allowed, but the CAS version is not. Check your model label carefully.
3. Do I need to clear my calculator memory?
Yes, test proctors may require you to clear all programs and history before the exam starts.
4. Can I bring two act permitted calculators?
Yes, you can bring a backup act permitted calculator, but only one can be on your desk at a time.
5. Are Casio graphing calculators permitted?
Most Casio models (like the fx-9860GII) are allowed, provided they don’t have CAS features.
6. What happens if I use a prohibited calculator?
You will be removed from the testing center, and your scores for all sections will be canceled without a refund.
7. Are scientific calculators allowed?
Almost all scientific calculators are allowed as they lack the prohibited advanced graphing and CAS features.
8. Is there a list of specifically named prohibited models?
Yes, the ACT website explicitly bans models like the TI-89, TI-92, and HP Prime.
