Common Misconceptions about ACT Allowed Calculators
Many students hold incorrect beliefs about the ACT calculator policy:
- “All graphing calculators are allowed.” False. While many graphing calculators are permitted, models with Computer Algebra System (CAS) functionality (like the TI-89, TI-92, or HP 48GII/50g) are strictly prohibited.
- “My calculator is old, so it must be fine.” Not necessarily. The age of the calculator doesn’t determine its allowance; its features do.
- “I can use my phone’s calculator app.” Absolutely not. Electronic devices like phones, smartwatches, or tablets are never allowed.
- “I can bring two calculators just in case one dies.” While bringing a backup is a good idea, both calculators must individually comply with the ACT Allowed Calculators policy.
B) ACT Allowed Calculators Policy and Prohibited Features Explanation
The ACT’s policy on calculators is designed to ensure fairness and prevent any unfair advantage. Instead of a complex mathematical formula, the “formula” for ACT Allowed Calculators is a set of clear rules regarding prohibited features. If a calculator possesses any of these features, it is not allowed.
Step-by-Step Derivation of Allowance Logic:
- Initial Check: Is the device a standard calculator (graphing, scientific, or basic)? If it’s a phone, smartwatch, tablet, or laptop, it’s immediately disallowed.
- QWERTY Keyboard Check: Does the calculator have a QWERTY (typewriter-style) keyboard? If yes, it’s disallowed.
- Computer Algebra System (CAS) Check: Does the calculator have CAS functionality? This includes models like the TI-89, TI-92, TI-Nspire CAS, HP 48GII, HP 50g. If yes, it’s disallowed.
- Paper Tape/Noise Check: Does the calculator have paper tape output or make noise? If yes, it’s disallowed.
- Wireless Communication/Pen Input Check: Does the calculator have wireless communication capabilities, a pen input device, or a power cord that requires an electrical outlet? If yes, it’s disallowed.
- Memory Clearing: While not a disallowance criterion, test proctors may require you to clear the memory of any calculator with a large memory capacity.
- Final Determination: If none of the above prohibited features are present, the calculator is generally considered an ACT Allowed Calculator.

E) Key Factors That Affect ACT Allowed Calculators Results
The ACT’s strict policy on calculators is driven by the need for a fair and secure testing environment. Several key factors determine whether a calculator falls into the category of ACT Allowed Calculators or is prohibited.
- Computer Algebra System (CAS) Functionality: This is perhaps the most significant factor. Calculators with CAS can perform symbolic algebra, solve equations with variables, and simplify expressions, which could give an unfair advantage on certain math problems. Examples include the TI-89, TI-92, and HP 48GII.
- QWERTY Keyboard: Any calculator that resembles a mini-computer keyboard is disallowed. This is primarily to prevent devices that could be used for communication or storing extensive notes, compromising test security.
- Wireless Communication Capabilities: Features like Bluetooth, Wi-Fi, or infrared ports are strictly prohibited. The ACT aims to prevent any form of external communication or data transfer during the exam.
- Paper Tape Output or Noise: Calculators that print on paper tape or make any audible noise are not allowed. Noise can be distracting to other test-takers, and paper tape could be used to record or share information.
- External Power Source Requirement: Calculators that need to be plugged into an electrical outlet are prohibited. All ACT Allowed Calculators must be battery-operated and portable.
- Pen Input Devices: Calculators that require a stylus or pen for input are generally disallowed. This is often associated with more advanced, tablet-like devices that might have prohibited functionalities.
- Memory Capacity and Programmability: While many programmable calculators are allowed (e.g., TI-84 Plus CE), proctors may require students to clear the memory of their calculators before the test. This is to prevent pre-programmed formulas or notes from being used.
- Physical Size and Obtrusiveness: Extremely large or bulky calculators might be questioned, though this is less common. The general rule is that the calculator should be a standard, handheld device.
Understanding these factors is crucial for ensuring your calculator is an ACT Allowed Calculator and avoiding any issues on test day.
