A) What is What Calculator Can I Use on the ACT?
The question “What calculator can I use on the ACT?” refers to the specific guidelines and restrictions set by ACT, Inc. regarding the use of calculators during the mathematics section of the ACT test. These rules are in place to ensure fairness, prevent cheating, and maintain the integrity of the standardized examination. Not all calculators are permitted, and bringing a prohibited device can lead to its confiscation or even dismissal from the test center.
This eligibility checker and guide are designed for anyone preparing for the ACT, especially students, parents, and educators. It helps clarify the often-confusing rules surrounding calculator usage. Understanding what calculator can I use on the ACT is crucial for test-day success, as a suitable calculator can be a valuable tool, while an unapproved one can cause significant stress and disruption.
Common Misconceptions about ACT Calculator Eligibility:
- “Any graphing calculator is fine.” This is false. While many graphing calculators are allowed, those with Computer Algebra Systems (CAS) or QWERTY keyboards are strictly prohibited.
- “My calculator is old, so it must be allowed.” Not necessarily. Even older models might have banned features like CAS.
- “I can use my phone’s calculator app.” Absolutely not. Cell phones and smart devices are never allowed as calculators on the ACT.
- “The proctor will tell me if my calculator is okay.” While proctors do check, it’s ultimately your responsibility to ensure your calculator complies. Don’t risk it on test day.
B) What Calculator Can I Use on the ACT? Formula and Mathematical Explanation
The “formula” for determining what calculator can I use on the ACT is not a mathematical equation in the traditional sense, but rather a set of logical rules based on the ACT’s official policy. It’s a decision tree that evaluates specific features and models against a list of prohibitions.
Step-by-Step Derivation of Eligibility:
- Check for Explicitly Banned Models: The ACT maintains a list of specific calculator models that are never allowed due to their advanced capabilities (e.g., CAS). If your calculator is on this list, it’s immediately “Not Allowed.”
- Check for QWERTY Keyboard: Does the calculator have a full QWERTY (typewriter-style) keyboard? If yes, it’s “Not Allowed.”
- Check for Computer Algebra System (CAS): Does the calculator have CAS functionality? If yes, it’s “Not Allowed.”
- Check for Internet/Wireless/Bluetooth: Does the calculator have any capability for internet access, wireless communication, or Bluetooth? If yes, it’s “Not Allowed.”
- Check for Camera/Scanning: Does the calculator have a camera or scanning function? If yes, it’s “Not Allowed.”
- Check for Paper Tape Output: Does the calculator print or produce paper tape? If yes, it’s “Not Allowed.”
- Check for Stylus Input: Does the calculator require a stylus for operation, or does it come with a removable stylus? If yes, it’s generally “Not Allowed” (unless the stylus is permanently attached and non-removable).
- Check for Phone/Communication Device: Is the device a cell phone, smartphone, or other communication device? If yes, it’s “Not Allowed.”
- Check for External Power Requirement: Does the calculator require an electrical outlet for power? If yes, it’s “Not Allowed” (must be battery-powered).
- Default to Allowed: If the calculator passes all the above checks (i.e., none of the prohibited features or models are present), then it is generally “Allowed.”

E) Key Factors That Affect What Calculator Can I Use on the ACT Results
Understanding the specific factors that influence ACT calculator eligibility is paramount. These factors are designed to maintain a level playing field and prevent unfair advantages.
- Computer Algebra System (CAS) Functionality: This is one of the most common reasons for a calculator to be banned. CAS calculators can perform symbolic manipulation (e.g., solving equations for variables, simplifying algebraic expressions), which the ACT considers an unfair advantage as it bypasses the need for manual algebraic skills.
- QWERTY Keyboards: Any calculator with a full QWERTY keyboard is strictly prohibited. The ACT views these as communication devices or tools for storing extensive notes, rather than purely mathematical instruments.
- Wireless Communication/Internet Access: Features like Wi-Fi, Bluetooth, or any form of internet connectivity are immediate disqualifiers. These capabilities could allow students to communicate with others or access external resources during the test, compromising test security.
- Camera or Scanning Capabilities: Devices that can capture images or scan documents are banned to prevent unauthorized recording or transmission of test content.
- Paper Tape Output: Calculators that print or produce a paper tape are not allowed. This is likely due to concerns about creating physical records of calculations that could be shared or used inappropriately.
- External Power Requirement: Calculators must be battery-powered. Test centers do not provide electrical outlets for calculators, and devices requiring an outlet are therefore prohibited.
- Specific Banned Models: The ACT explicitly bans certain models, such as the TI-89, TI-92, Voyage 200, HP 48GII, and Casio ClassPad series. These are typically high-end calculators with CAS or other advanced features that violate policy. Always check the official ACT website for the most current list.
- Stylus Input: While some touch-screen calculators are allowed, those that require a stylus for operation (unless the stylus is permanently attached and non-removable) are generally not permitted. This is to prevent the use of external devices that could potentially store information.
Being aware of these factors is crucial when deciding what calculator can I use on the ACT. It’s not just about having a powerful calculator, but having the *right* kind of calculator.
