What is the ACT Calculator Policy?
The ACT calculator policy is a set of rules designed to ensure fairness and test security for all students taking the ACT. While all math problems on the ACT can be solved without a calculator, using one is strongly recommended to save time on complex calculations. The core of the policy dictates which types of calculators are permitted and which are strictly prohibited. Understanding what calculators can you use for the ACT is a crucial part of test preparation. The policy ensures that no student has an unfair advantage by using a device with advanced functionalities that solve problems for them.
In general, you may use any 4-function, scientific, or graphing calculator, unless it is on the official prohibited list. The most common reason for a calculator to be banned is the inclusion of a Computer Algebra System (CAS). You are also not allowed to use calculators on your phone, tablet, or laptop.
Understanding the ACT’s Calculator Rules
The rules are not about specific brands but about functionality. The ACT explicitly prohibits any calculator that can solve algebraic equations symbolically, has a QWERTY keyboard, or can communicate wirelessly. The goal is to test your math skills, not your ability to operate a mini-computer. This section breaks down the “formula” for determining if a calculator is compliant.
| Feature | Meaning | Status on ACT | Typical Range/Example |
|---|---|---|---|
| Basic 4-Function | Performs arithmetic (+, -, *, /). | Permitted | Any standard basic calculator. |
| Scientific | Handles exponents, logs, trig functions. | Permitted | TI-30X, Casio fx-115ES |
| Graphing | Plots graphs of functions. | Permitted (if non-CAS) | TI-84 Plus, TI-Nspire (non-CAS) |
| Computer Algebra System (CAS) | Manipulates and solves algebraic expressions symbolically. | Prohibited | TI-89, TI-Nspire CAS, HP Prime |
| QWERTY Keyboard | A typewriter-style keyboard. | Prohibited | N/A (no modern calculators have this) |
| Wireless Communication | Infrared, WiFi, Bluetooth capabilities. | Prohibited | Phones, smartwatches, some older HP models |
Practical Examples (Real-World Use Cases)
Let’s apply the ACT calculator policy to two common scenarios.
Example 1: Student with a TI-84 Plus CE
A student brings a Texas Instruments TI-84 Plus CE to the test. They use our guide and check the boxes for “Math Section” and note that it has no CAS, QWERTY keyboard, or wireless features.
Inputs: Math Section = Yes, Prohibited Features = No.
Output: The calculator is PERMITTED.
Interpretation: The TI-84 Plus CE is one of the most popular and widely accepted graphing calculators for the ACT. It provides powerful graphing and calculation capabilities without violating the rules. This is a perfect example of what calculators can you use for the ACT.
Example 2: Student with a TI-89 Titanium
Another student has a Texas Instruments TI-89 Titanium. This calculator is known for its advanced features.
Inputs: Math Section = Yes, Prohibited Features = Yes (Has a CAS).
Output: The calculator is PROHIBITED.
Interpretation: The TI-89 is explicitly banned by the ACT because its built-in Computer Algebra System (CAS) can perform algebraic manipulations, giving the user an unfair advantage. The student must bring a different, non-CAS calculator.
How to Use This ACT Calculator Policy Guide
Using this interactive tool is a straightforward way to check what calculators can you use for the act. Follow these simple steps:
- Select the Test Section: Check the box corresponding to the ACT test section you are in. Remember, calculators are only allowed on the Math Test.
- Identify Prohibited Features: Review your calculator’s specifications. Check any boxes for features your calculator has, such as a Computer Algebra System (CAS) or a QWERTY keyboard.
- Review the Result: The tool will instantly display a primary result: PERMITTED, PROHIBITED, or a warning. The explanation below will provide context for the decision.
- Check Intermediate Values: The “Permitted Usage” and “Prohibited Features” cards give you more specific details based on your selections.
- Reset or Copy: Use the “Reset” button to start over or the “Copy Results” button to save a summary of the findings.
Key Factors That Affect ACT Calculator Compliance
Several factors determine whether your calculator will be allowed on test day. Paying attention to these details is essential. The core question for students is always, “what calculators can you use for the act?” and these factors provide the answer.
- Computer Algebra System (CAS): This is the most common reason for a calculator to be prohibited. A CAS can solve `x + 2 = 5` for `x`, which the ACT considers cheating.
- QWERTY Keyboards: Calculators with typewriter-like keyboards are banned to prevent the storage of notes.
- Communication Capabilities: Any device that can communicate wirelessly (Infrared, Bluetooth, Wi-Fi) is not allowed. This includes smartphones, smartwatches, and laptops.
- Power Source: Calculators needing an electrical outlet are not permitted. Ensure your calculator is battery-powered and bring extra batteries just in case.
- Noise and Printing: Calculators that make noise or print to paper tape are prohibited to avoid distracting other test-takers.
- Official Prohibited List: The ACT maintains an official, though not exhaustive, list of banned calculators. Always check the official ACT website for the latest updates on what calculators can you use for the act.
Frequently Asked Questions (FAQ)
No. All phones, tablets, smartwatches, and laptops are strictly prohibited from use during the test.
If a proctor identifies your calculator as prohibited, it will be confiscated for the duration of the test, and you may be dismissed from the testing site.
It depends on the model. The TI-Nspire (non-CAS) is permitted, but the TI-Nspire CAS is explicitly prohibited. You must ensure your model does not have “CAS” printed on it.
The ACT allows you to use programs and stored functions in your calculator’s memory. However, you cannot store documents or test materials. It’s good practice to know the rules to avoid any issues.
Yes, generally all scientific calculators are allowed as they do not contain prohibited features like CAS. They are a safe and effective choice for the ACT.
No. Sharing calculators during the test is not permitted under any circumstances. You must bring your own.
The “best” calculator is one you are comfortable with that is also permitted. Many students prefer the TI-84 Plus series because it balances powerful features with ease of use and is fully compliant with the ACT calculator policy. The ultimate answer to “what calculators can you use for the act” depends on your familiarity.
You are responsible for your own equipment. Proctors will not provide batteries. It is highly recommended to install fresh batteries before the test and/or bring a backup calculator that is also on the approved list.
