Key Factors That Affect “Can a Calculator Be Used on the ACT” Results

The ACT’s calculator policy is designed to create a level playing field. Several key factors determine whether a calculator can be used on the ACT. Understanding these helps clarify why certain models are allowed while others are not.

  1. Computer Algebra System (CAS) Functionality: This is one of the most common reasons for prohibition. CAS calculators can perform symbolic manipulation, solving equations, differentiating, and integrating algebraically. This capability is deemed an unfair advantage, as the ACT math section tests a student’s ability to perform these operations manually or with basic numerical assistance.
  2. QWERTY Keyboard: Calculators with a full QWERTY (typewriter-style) keyboard are strictly prohibited. The ACT views these as too similar to computers or communication devices, which could potentially store notes or provide an unfair advantage.
  3. Wireless Communication Capabilities: Any calculator with Bluetooth, Wi-Fi, cellular, or other wireless communication features is forbidden. This prevents students from communicating with others or accessing external resources during the test.
  4. Internet Access: Directly related to wireless communication, any device that can connect to the internet is prohibited. This is to prevent access to online resources, study guides, or communication platforms.
  5. Stylus/Pen Input, Camera, or Phone Functionality: Devices that require a stylus for input, have a built-in camera, or can function as a phone are all prohibited. These features blur the line between a calculator and a general-purpose electronic device, raising concerns about cheating and test security.
  6. Paper Tape/Printing Capability: Calculators that print calculations on paper tape are not allowed. The paper output could be used to store information or disrupt the testing environment.
  7. Device Type (Handheld Computer, Tablet, etc.): The ACT explicitly prohibits handheld computers, laptops, tablets, smartwatches, and any other general-purpose computing devices. Only dedicated calculators that meet the specific criteria are permitted.
  8. External Power Source Requirement: Calculators that require an electrical outlet for operation are not allowed. Test centers typically do not provide power outlets for calculators.
