What is the ACT Calculator Policy?
The ACT calculator policy outlines the specific types and features of calculators that are permitted during the ACT math section. This policy is crucial for all test-takers to understand, as bringing a prohibited calculator can lead to dismissal from the test center and invalidation of scores. The primary goal of the policy is to ensure fairness and prevent any student from having an unfair advantage due to advanced calculator capabilities or access to external information.
Who should use it: Every student planning to take the ACT exam should familiarize themselves with the ACT calculator policy. This includes high school students, homeschoolers, and anyone preparing for college admissions. Understanding what calculator can you use on the ACT is a fundamental step in test preparation.
Common misconceptions:
- “All graphing calculators are allowed.” This is false. While many popular graphing calculators (like the TI-83/84 series) are allowed, those with Computer Algebra Systems (CAS) or QWERTY keyboards are strictly prohibited.
- “My calculator is old, so it must be fine.” Age doesn’t guarantee compliance. Some older, very powerful calculators might still have prohibited features like CAS.
- “I can just use my phone’s calculator.” Absolutely not. All electronic devices with communication capabilities, including phones, smartwatches, and tablets, are strictly forbidden.
- “They won’t check that closely.” ACT proctors are trained to check calculators. Don’t risk your test day by bringing a non-compliant device.
ACT Calculator Policy Rules and Rationale
The ACT’s rules regarding what calculator can you use on the ACT are designed to create a standardized testing environment. Here’s a breakdown of the key rules and the reasoning behind them:
General Rules:
- Allowed Calculators: Most basic four-function, scientific, and approved graphing calculators are permitted.
- Prohibited Features: Calculators with certain advanced features are not allowed.
- Prohibited Devices: Any device that can communicate, record, or print is forbidden.
Specific Prohibitions:
- Calculators with Computer Algebra System (CAS): These calculators can perform symbolic manipulation, solving equations algebraically, differentiating, and integrating. The ACT wants to test your understanding of these concepts, not your calculator’s ability to do them for you. Examples: TI-89, TI-92, Voyage 200, HP 48GII, HP 50g, Casio ClassPad 300/330/400.

Key Factors That Determine ACT Calculator Eligibility
Understanding what calculator can you use on the ACT involves more than just knowing a list of models. Several key factors dictate whether a calculator meets the ACT’s strict requirements:
- Computer Algebra System (CAS) Functionality: This is perhaps the most significant factor. Calculators with CAS can solve equations symbolically, perform calculus operations, and simplify algebraic expressions. The ACT prohibits these because they bypass the need for students to demonstrate their own algebraic and calculus skills. Examples include the TI-89, TI-92, and HP 50g.
- QWERTY Keyboard Layout: Any calculator featuring a full QWERTY (typewriter-style) keyboard is disallowed. The ACT views these as too similar to computers, raising concerns about potential for storing notes or accessing unauthorized information. Even if the keyboard is small, if it’s QWERTY, it’s out.
- Wireless Communication Capabilities: Calculators or devices that can connect to the internet, communicate wirelessly (e.g., Bluetooth, Wi-Fi), or use cellular data are strictly prohibited. This rule is in place to prevent cheating by accessing external resources or communicating with others during the exam. This includes smartphones, smartwatches, and tablets.
- Audio/Video Recording and Playback: Devices with the ability to record or play back audio or video are not allowed. This prevents students from recording test questions or playing back pre-recorded study materials.
- Paper Tape/Printing Functionality: Calculators that print a record of calculations are forbidden. The ACT does not allow any external output from calculators during the test.
- Stylus/Pen Input: Calculators that require or allow input via a stylus or pen are generally not permitted, as these often accompany more advanced, prohibited features or could be used for unauthorized note-taking.
- Noise Production: Any calculator that makes noise (e.g., beeps, speaks) is not allowed, as it can disturb other test-takers. Ensure your calculator’s sound is turned off or disabled.
- External Power Source: While not a direct prohibition, calculators requiring an external power source (i.e., needing to be plugged into an outlet) are impractical and generally not allowed due to test center limitations. Battery-operated calculators are the standard.
Understanding these factors is crucial for selecting an appropriate calculator and ensuring compliance with the calculator restrictions ACT. Always aim for a calculator that enhances your calculation speed without providing an unfair advantage in problem-solving.
