What Calculator Can You Use On Act

Is Your Calculator Allowed on the ACT?

Enter your calculator’s model number below to instantly check if it’s permitted on the ACT test. Our tool helps you understand **what calculator you can use on act** and avoid issues on test day.

What is the ACT Calculator Policy?

The ACT calculator policy defines the rules for **what calculator you can use on act** during the mathematics portion of the test. The policy is designed to ensure fairness and prevent any student from having an unfair advantage. While most calculators, including many graphing calculators, are permitted, certain types with advanced functionalities are strictly prohibited. Understanding these rules is crucial for a smooth test day experience.

This policy primarily targets calculators with features that can solve complex algebraic equations automatically (Computer Algebra Systems or CAS), have QWERTY keyboards, or possess communication capabilities. The goal is to test your mathematical reasoning skills, not your ability to operate a mini-computer. Anyone taking the ACT math test should familiarize themselves with this policy to ensure their device is compliant.

A common misconception is that all graphing calculators are banned. This is incorrect. Most standard graphing calculators, like the popular TI-84 series, are perfectly acceptable. The key is to check for specific prohibited features rather than the general type of calculator. Our checker above simplifies this process, giving you a clear answer on **what calculator you can use on act**.

ACT Calculator Policy Logic Explained

Unlike a mathematical formula, the ACT’s calculator policy is a set of rules and conditions. Our checker uses this logic to determine a calculator’s status. The process involves checking the model number against lists of known permitted and prohibited devices, and identifying features that disqualify a calculator.

The core logic revolves around identifying prohibited features. Here’s a step-by-step breakdown of how the policy is applied:

1. Check for Explicit Prohibition: The ACT explicitly bans calculators with Computer Algebra Systems (CAS). Our tool checks if the model name contains “CAS” or is on the known list of CAS calculators (e.g., TI-89, TI-Nspire CAS, HP Prime).
2. Check for QWERTY Keyboard: Any device with a typewriter-style keyboard is forbidden.
3. Check for Communication Features: Calculators with infrared, Bluetooth, or Wi-Fi capabilities are not allowed.
4. Check for Prohibited Device Types: The policy bans laptops, tablets, cell phones, and smartwatches.
5. Check for Permitted Status: If a calculator does not have any prohibited features and is a standard four-function, scientific, or non-CAS graphing calculator, it is generally permitted.

This rule-based system ensures that the focus remains on your problem-solving abilities. For more information on test preparation, you might find our guide on SAT vs. ACT scores helpful.

Summary of Prohibited vs. Permitted Calculator Features

Practical Examples

Example 1: A Common Graphing Calculator

• Student’s Calculator: Texas Instruments TI-84 Plus CE
• Checker Input: “TI-84 Plus CE”
• Result: Permitted
• Interpretation: The TI-84 Plus CE is one of the most common calculators used for the ACT. It has graphing capabilities but does not have a prohibited Computer Algebra System (CAS). It is fully compliant with the ACT calculator policy, and the student can use it on the test without any modifications. This is a clear example of **what calculator you can use on act**.

Example 2: A Prohibited CAS Calculator

• Student’s Calculator: HP Prime G2
• Checker Input: “HP Prime”
• Result: Prohibited
• Interpretation: The HP Prime is a powerful graphing calculator, but it includes a built-in Computer Algebra System (CAS). The CAS feature allows it to perform symbolic algebraic manipulations, which is explicitly forbidden by the ACT. The student must find an alternative, non-CAS calculator for test day. This highlights a key restriction when determining **what calculator you can use on act**.

Key Factors That Affect Calculator Eligibility

Several key features determine whether a calculator is allowed on the ACT. Understanding these factors is essential for choosing the right device. If you’re investing in a new calculator, consider its long-term value for college courses by reading about college savings plans.

1. Computer Algebra System (CAS): This is the most common reason for a calculator to be banned. A CAS can simplify expressions, solve equations, and perform calculus operations symbolically. The ACT prohibits these to ensure they are testing your skills, not the calculator’s.
2. QWERTY Keyboard: Calculators with a full, typewriter-style keyboard are prohibited. This is to prevent devices that could store notes or function like a computer.
3. Communication Technology: Any calculator that can communicate wirelessly (infrared, Bluetooth, Wi-Fi) is banned to prevent cheating.
4. Device Type: The policy is strict about the device itself. You cannot use the calculator function on a phone, tablet, laptop, or smartwatch, even if it’s in “airplane mode.”
5. Power Source: The calculator must be battery-powered. Devices that need to be plugged into an electrical outlet are not permitted in the testing room.
6. Physical Modifications: Some calculators, like the TI-Nspire, come in both CAS and non-CAS versions. Ensure you have the correct version. Some policies mention that features must be removed, but it’s safer and easier to simply use a compliant calculator from the start. Knowing **what calculator you can use on act** is the first step to success.
