What is the ACT Calculator Policy?

The ACT calculator policy outlines the rules for which calculators students can use during the mathematics portion of the ACT test. The policy is designed to ensure fairness for all test-takers and prevent any unfair advantages. While you can use a calculator, it’s important to know that every question on the ACT Math test can be solved without one. The main purpose of asking “can you use a calculator on the ACT” is to find a tool that helps you work efficiently and accurately under timed conditions. You are only allowed to use a calculator on the Math section of the test.

A common misconception is that all graphing calculators are banned, which is not true. Many popular graphing calculators, like the TI-83 and TI-84 series, are perfectly acceptable. The restrictions primarily target calculators with specific advanced functionalities like a Computer Algebra System (CAS).

ACT Calculator Rules and Mathematical Explanation

The core of the ACT’s policy isn’t about specific brands but about functionality. The guiding principle is to prohibit any device that can solve algebraic equations symbolically, has a QWERTY keyboard, or can communicate wirelessly. Understanding these rules is essential for anyone wondering, “can you use a calculator on the ACT”.

Prohibited vs. Permitted Features

The “formula” for determining if a calculator is allowed involves checking its features against the prohibited list. Here’s a breakdown of the key variables:

Variable (Feature) Meaning Status on ACT Typical Range/Example
Computer Algebra System (CAS) Can simplify, factor, and solve algebraic expressions symbolically. Prohibited TI-89, TI-Nspire CAS, HP Prime
QWERTY Keyboard A typewriter-style keyboard. Prohibited Calculators with letter keys in A-Z layout
Wireless/Infrared Communication Ability to connect to other devices or the internet. Prohibited (or must be disabled/covered) Bluetooth, Wi-Fi, or IR ports (like on HP 38G/39G/48G)
Graphing Capability Can plot equations on a coordinate plane. Permitted (if non-CAS) TI-84 Plus, TI-Nspire (non-CAS), Casio fx-9750GII
Scientific Functions Performs trigonometric, logarithmic, and exponential functions. Permitted TI-30XS, Casio fx-115ES
Paper Tape or Noise Prints results or makes sounds. Modification Required Must remove tape and mute sound

Practical Examples (Real-World Use Cases)

Example 1: The Compliant Student

A student has a TI-84 Plus CE. They use the calculator on this page and enter “TI-84 Plus CE”.

  • Input: TI-84 Plus CE
  • Output: PERMITTED
  • Interpretation: The TI-84 Plus series is one of the most common and widely approved calculators for the ACT. It has graphing capabilities but does not have a prohibited Computer Algebra System (CAS). This is a great choice for test day. The answer to “can you use calculator on act” for this model is a clear yes.

Example 2: The Prohibited Calculator

Another student owns a TI-89 Titanium. They are unsure about the rules.

  • Input: TI-89
  • Output: PROHIBITED
  • Interpretation: The TI-89 is explicitly banned by the ACT because it contains a Computer Algebra System (CAS). This feature allows it to perform algebraic manipulations that are not allowed, giving an unfair advantage. The student will need to acquire a permitted calculator before the test.

Key Factors That Affect Calculator Permissibility

Several key factors determine whether you can you use a calculator on the ACT. Understanding these will help you choose the right tool for test day.

1. QWERTY Keypad

Any calculator with a keyboard layout similar to a computer or phone (QWERTY, AZERTY, etc.) is strictly forbidden. This rule prevents students from being able to type and store notes easily.

2. Computer Algebra System (CAS)

CAS can perform symbolic manipulation (e.g., factoring polynomials, solving for variables). The ACT has a complex stance on this. Some CAS calculators are banned outright (like the TI-92), while others (like the TI-Nspire CAS) are allowed only if the CAS is disabled. This is a crucial factor in determining if you can you use a calculator on the ACT.

3. Wireless Communication

Any form of wireless communication (Wi-Fi, Bluetooth, infrared) is prohibited. This is to prevent any possibility of cheating by communicating with other devices or people during the test.

4. Power Source

Calculators must be battery-operated. Devices that require an external power source, like being plugged into a wall, are not allowed in the testing room.

5. Explicitly Prohibited List

The ACT maintains a list of specific models that are always banned, regardless of their features. This list includes models like the Texas Instruments TI-89 and TI-92 series, and the Hewlett-Packard HP 49G and HP 50G. Always check this list. Our ACT math section tips can help you practice with a permitted calculator.

6. Non-Calculator Functionality

If the device is primarily something other than a calculator (e.g., a smartphone, tablet, laptop, or smartwatch), it cannot be used, even if you are only using its calculator app. The device must be a dedicated calculator.

Frequently Asked Questions (FAQ)

1. Can I use a TI-89 on the ACT?
