Key Factors That Affect “Calculator You Can Use on ACT” Results
The ACT’s policy on what constitutes a “calculator you can use on ACT” is driven by several key factors, primarily focused on maintaining a level playing field and preventing academic dishonesty. Understanding these factors helps clarify why certain features are prohibited.
- QWERTY Keyboards: Calculators with QWERTY keyboards (like the TI-92 or Voyage 200) are banned because they resemble computer keyboards. The ACT fears these could be used for storing notes, communicating, or providing an unfair advantage in text-based problem-solving.
- Computer Algebra Systems (CAS): CAS functionality allows calculators to perform symbolic manipulation, solve equations with variables, and simplify complex algebraic expressions. This capability could allow students to bypass the algebraic steps required to solve problems, thus not accurately assessing their understanding. Examples include the TI-Nspire CX CAS and HP Prime. A “calculator you can use on ACT” must not have CAS.
- Wireless Communication Capabilities: Any calculator with Bluetooth, Wi-Fi, infrared, or other wireless communication features is strictly prohibited. This is a critical measure to prevent cheating, such as receiving answers or communicating with other test-takers or external sources during the exam.
- Paper Tape and Noise Production: Calculators that print paper tape or make audible sounds (beeps, clicks) are disallowed to prevent distractions to other test-takers. The testing environment must remain quiet and focused.
- External Power Sources: Calculators requiring an electrical outlet are prohibited for practical reasons (lack of outlets in testing rooms) and to prevent potential power issues or distractions. A “calculator you can use on ACT” must be battery-powered.
- Device Type (Smartphones, Tablets, etc.): This is perhaps the most obvious prohibition. Any device that functions as a phone, tablet, laptop, or smartwatch is strictly forbidden. These devices have extensive communication, storage, and internet access capabilities that would fundamentally compromise the integrity of the ACT.
- Memory and Storage: While not explicitly a “prohibited feature” in the same way as CAS, the ACT generally prohibits calculators with excessive memory that could be used to store large amounts of text, formulas, or programs that give an unfair advantage. Most standard graphing calculators (like the TI-84 Plus CE) have acceptable memory limits.
Each of these factors contributes to the ACT’s definition of what is and isn’t a “calculator you can use on ACT,” ensuring a fair and secure testing experience for all.
