What is the ACT Calculator Policy?
The ACT Calculator Policy is a set of rules established by ACT, Inc. to ensure fairness and test security during the administration of the ACT exam. The policy specifies which types of calculators are permitted, which are prohibited, and what modifications are required for certain models. The core principle is to allow students to use a helpful tool for the math section without giving anyone an unfair advantage through devices with advanced communication or symbolic manipulation capabilities. Understanding the ACT Calculator Policy is crucial for any student planning to take the test.
Who Should Use This Policy Checker?
This tool is designed for high school students, parents, and educators who need a quick and clear answer about whether a specific calculator is approved for the ACT. If you’re preparing for the test and are unsure about your calculator, this tool provides instant clarification based on the official ACT Calculator Policy.
Common Misconceptions
A common misconception is that all graphing calculators are banned. This is false; most graphing calculators, like the popular TI-84 Plus series, are perfectly acceptable. The ban focuses on calculators with specific functionalities like a Computer Algebra System (CAS), not the graphing capability itself. Another myth is that you need an expensive graphing calculator to succeed. In reality, every math problem on the ACT can be solved without a calculator, and a familiar scientific calculator is often more than sufficient.
ACT Calculator Policy: The Decision Logic Explained
Instead of a mathematical formula, the ACT Calculator Policy uses a rule-based decision logic to determine if a calculator is permitted. This logic can be broken down into a series of checks. If a calculator fails any of these critical checks, it is prohibited. This calculator automates this logical process for you.
The fundamental logic is: A calculator is **PERMITTED** if and only if it is NOT on the specific prohibited model list AND does NOT have any prohibited features (like CAS, QWERTY keyboard, wireless access, etc.).
Variables of the Policy
The “variables” in the ACT Calculator Policy are the features and characteristics of the calculator itself. The test administrators check these variables to make a decision.
| Variable (Feature) | Meaning | Permitted Value | Prohibited Value |
|---|---|---|---|
| Computer Algebra System (CAS) | Ability to solve algebra symbolically (e.g., solve for x). | No | Yes |
| Keyboard Type | The layout of lettered keys. | Alphabetic (ABCDE) | QWERTY |
| Communication | Ability to connect to other devices or the internet. | None | Infrared, Wi-Fi, Bluetooth |
| Power Source | How the calculator gets power. | Battery or Solar | External Power Cord |
| Platform | The physical nature of the device. | Dedicated Handheld Device | Phone, Tablet, or Laptop App |
| Specific Model Name | The model number printed on the calculator. | Not on banned list (e.g., TI-84) | On banned list (e.g., TI-89, HP Prime) |
Practical Examples (Real-World Use Cases)
Example 1: The Compliant Student (TI-84 Plus)
- Inputs: Model Name = “TI-84 Plus”, All feature checkboxes are unchecked.
- Logic Check: The model “TI-84 Plus” is not on the prohibited list. It does not have a CAS, a QWERTY keyboard, or any other forbidden features.
- Output: PERMITTED. This calculator is one of the most common and recommended models for the ACT.
- Interpretation: The student can confidently bring this calculator to the test center. It is fully compliant with the ACT Calculator Policy.
Example 2: The Prohibited Calculator (TI-89)
- Inputs: Model Name = “Texas Instruments TI-89”, The “Computer Algebra System (CAS)” box is checked.
- Logic Check: The model name contains “TI-89,” which is on the explicitly prohibited list. Furthermore, it has a CAS. This fails the check on two counts.
- Output: PROHIBITED. Reason: This model is explicitly banned and contains a Computer Algebra System (CAS).
- Interpretation: The student absolutely cannot use this calculator on the ACT. Doing so would risk dismissal from the test. They need to acquire a different, compliant calculator.
How to Use This ACT Calculator Policy Checker
- Enter Model Name: Start by typing the model name of your calculator (e.g., “TI-30XS”, “Casio fx-9750GII”) into the first input field. The policy check will begin instantly.
- Identify Prohibited Features: Read through the checklist of prohibited features. If your calculator has any of them, check the corresponding box. For example, if it’s a “TI-Nspire CAS,” you would check the CAS box.
- Review the Result: The tool will immediately display a primary result: “PERMITTED,” “PROHIBITED,” or “MODIFICATION REQUIRED.” A summary will explain the reasoning.
- Check the Chart: The bar chart at the bottom provides a quick visual of which rules your calculator violates. A tall red bar indicates a prohibited feature you have selected.
- Read the Details: For a full understanding, read the detailed article below the calculator to learn more about the nuances of the ACT Calculator Policy.
Key Factors That Affect the ACT Calculator Policy
Several key factors determine whether a calculator is allowed. Understanding these helps you see the “why” behind the ACT Calculator Policy.
- Computer Algebra System (CAS): This is the most common reason for a graphing calculator to be banned. CAS can perform symbolic algebra, which the ACT considers a form of cheating as it solves problems for the student. Models like the TI-89 and HP Prime are banned for this reason.
- QWERTY Keyboards: Calculators with a letter keyboard in the same layout as a computer (QWERTY) are prohibited. This is to prevent the use of devices with stored text or programs that are easily accessible.
- Communication Capabilities: Any device that can communicate with other devices or the internet is strictly forbidden. This includes calculators with infrared ports (which must be covered), Bluetooth, or Wi-Fi. This rule prevents cheating and protects test security.
- Power Source: Calculators that need to be plugged into a wall outlet are not allowed. Your calculator must be battery-operated to ensure it can be used at a testing desk without creating a hazard.
- Device Type: The calculator must be a standalone, handheld device. You cannot use a calculator app on a smartphone, tablet, smartwatch, or laptop. Using any of these devices will result in immediate dismissal.
- Noise and Printing: Calculators that make noise must be muted. Calculators that can print to a paper tape must have the tape removed before the test. This is to prevent disruptions in the testing room.
Frequently Asked Questions (FAQ)
1. Can I use a graphing calculator on the ACT?
Yes, most graphing calculators are permitted on the ACT, as long as they are not on the prohibited list and do not have a CAS. Popular models like the TI-84 Plus and Casio fx-9750GII are perfectly fine.
2. Is the TI-84 Plus allowed on the ACT?
Yes, all versions of the TI-84 Plus (including the Plus, Plus CE, and Plus CE Python) are allowed on the ACT. They are some of the most recommended calculators for the test.
3. What happens if I bring a banned calculator?
If you are caught using a prohibited calculator during the test, you will likely be dismissed from the testing center, and your score will be canceled. It is your responsibility to ensure your calculator is compliant with the ACT Calculator Policy.
4. Do I need to clear the memory on my calculator?
The ACT does not require you to clear your calculator’s memory before the test. However, you cannot store programs that have computer algebra system functionality. To be safe, it’s a good idea to remove any non-essential programs.
5. Can I use a calculator on all sections of the ACT?
No, calculators are only permitted during the 60-minute Mathematics Test. Using a calculator on any other section (English, Reading, Science) is prohibited and could lead to disqualification.
6. Can I share my calculator with another student?
No, sharing calculators is strictly forbidden. You must bring your own calculator. It is also recommended to bring a backup calculator or extra batteries in case your primary one fails.
7. What is a Computer Algebra System (CAS)?
A Computer Algebra System (CAS) is a software feature that allows a calculator to manipulate mathematical expressions in a symbolic way. For instance, it can solve an equation like ‘3x + 5 = 11’ to show ‘x = 2’ or simplify ‘x^2 * x^3’ to ‘x^5’. Because this automates algebra, CAS calculators are banned.
8. Are scientific calculators allowed?
Yes, all standard scientific calculators are allowed and are often a great choice for the ACT. Models like the TI-30XS MultiView are excellent because they are powerful enough for the test but less complex than a graphing calculator.
