What is ACT Calculator Policy?
The ACT calculator policy outlines the specific rules and guidelines regarding which calculators are permitted for use on the ACT Math Test. Understanding whether you are able to use a graphing calculator on ACT is crucial for test-takers, as bringing a prohibited calculator can lead to its confiscation or even dismissal from the test. The policy aims to ensure fairness and prevent any unfair advantage that certain advanced calculator features might provide.
The ACT allows most four-function, scientific, and graphing calculators, but it explicitly prohibits certain types and features. This includes calculators with computer algebra systems (CAS), QWERTY keyboards, wireless communication capabilities, cameras, or pen-input devices. The primary goal is to allow tools that aid in computation and graphing without providing solutions or excessive assistance that bypasses the mathematical reasoning being tested.
Who Should Understand the ACT Calculator Policy?
- All ACT Test-Takers: Every student planning to take the ACT, especially the Math section, must be familiar with these rules.
- Parents and Educators: To guide students in selecting appropriate calculators for test preparation and the actual exam.
- Test Center Staff: To enforce the rules consistently and fairly.
Common Misconceptions About Using a Graphing Calculator on ACT:
- “All graphing calculators are allowed.” This is false. While many popular graphing calculators like the TI-84 Plus CE are allowed, models with specific prohibited features (e.g., CAS, QWERTY) are not.
- “Only basic calculators are allowed.” Also false. Graphing calculators are generally permitted, provided they comply with the rules.
- “The ACT provides calculators.” The ACT does not provide calculators. Students are responsible for bringing their own approved calculator.
- “I can use my phone’s calculator app.” Absolutely not. Electronic devices like phones, smartwatches, or tablets are strictly prohibited.
ACT Calculator Policy Logic and Explanation
Determining if you are able to use a graphing calculator on ACT involves a logical evaluation of its features and model against the official ACT guidelines. There isn’t a mathematical “formula” in the traditional sense, but rather a decision-tree logic that prioritizes certain prohibitions. The core principle is that any feature that could give an unfair advantage by solving problems symbolically, communicating externally, or storing excessive information is disallowed.
Step-by-Step Derivation of Eligibility:
- Initial Check for Prohibited Features: The first and most critical step is to identify if the calculator possesses any explicitly prohibited features. These include:
- QWERTY (typewriter-style) keyboards
- Computer Algebra Systems (CAS)
- Wireless communication capabilities (Bluetooth, Wi-Fi, infrared, etc.)
- Cameras
- Pen-input or stylus functionality
If any of these features are present, the calculator is immediately deemed “Not Allowed,” regardless of its brand or model.
- Check for Explicitly Prohibited Models: Even if a calculator doesn’t appear to have the above features, certain models are explicitly listed as prohibited by the ACT due to their advanced capabilities or potential for misuse. Examples include the TI-89, TI-92, TI-Nspire CX CAS, and HP 48GII. If the calculator matches one of these models, it is “Not Allowed.”
- General Allowance: If a calculator passes both the prohibited features check and the explicitly prohibited models check, it is generally considered “Allowed.” This typically covers most standard graphing calculators like the TI-83, TI-84 series, and many Casio fx-series models.
This hierarchical logic ensures that the most critical prohibitions are addressed first, providing a clear and consistent method for determining eligibility.

Practical Examples (Real-World Use Cases)
To illustrate how to determine if you are able to use a graphing calculator on ACT, let’s look at a few common scenarios:
Example 1: Texas Instruments TI-84 Plus CE
- Calculator Brand: Texas Instruments (TI)
- Calculator Model: TI-84 Plus CE
- Has QWERTY Keyboard: No
- Has CAS: No
- Has Wireless: No
- Has Camera: No
- Has Pen-Input: No
Output: Your calculator is Allowed on the ACT Math Test.
Interpretation: The TI-84 Plus CE is one of the most popular and widely accepted graphing calculators for the ACT. It lacks all the prohibited features and is not on the explicitly prohibited models list. This makes it a safe and effective choice for the exam.
Example 2: Texas Instruments TI-Nspire CX CAS
- Calculator Brand: Texas Instruments (TI)
- Calculator Model: TI-Nspire CX CAS
- Has QWERTY Keyboard: No
- Has CAS: Yes
- Has Wireless: No
- Has Camera: No
- Has Pen-Input: No
Output: Your calculator is Not Allowed on the ACT Math Test.
Interpretation: Despite being a powerful graphing calculator, the “CAS” in its name indicates it has a Computer Algebra System. This feature is explicitly prohibited by the ACT, making this model ineligible. Even if it didn’t have CAS, the TI-Nspire CX CAS is also on the list of explicitly prohibited models.
Example 3: HP Prime (with CAS enabled)
- Calculator Brand: Hewlett-Packard (HP)
- Calculator Model: HP Prime
- Has QWERTY Keyboard: No
- Has CAS: Yes
- Has Wireless: No
- Has Camera: No
- Has Pen-Input: No
Output: Your calculator is Not Allowed on the ACT Math Test.
Interpretation: The HP Prime is a sophisticated graphing calculator that often includes CAS functionality. If the CAS is enabled or present, the calculator is prohibited. Some versions of the HP Prime might allow disabling CAS, but it’s safer to use a calculator without this feature to avoid any issues on test day.

Key Factors That Affect ACT Calculator Policy Results
When determining if you are able to use a graphing calculator on ACT, several key factors play a critical role. These factors are the primary reasons why certain calculators are prohibited, ensuring a level playing field for all test-takers.
- QWERTY Keyboards: Calculators equipped with a full QWERTY (typewriter-style) keyboard are strictly prohibited. The ACT views these as too similar to a computer keyboard, which could potentially be used for storing notes or communicating, thus violating test security.
- Computer Algebra Systems (CAS): CAS functionality allows calculators to perform symbolic manipulation, such as solving equations for variables, simplifying algebraic expressions, or performing calculus operations symbolically. Since the ACT Math test assesses these very skills, a CAS calculator would provide an unfair advantage by directly solving problems that students are expected to work through.
- Wireless Communication Capabilities: Any calculator with features like Bluetooth, Wi-Fi, infrared data transfer, or cellular connectivity is prohibited. These capabilities could be used to send or receive information during the test, compromising the integrity of the exam.
- Cameras: Calculators with built-in cameras are not allowed. A camera could be used to photograph test questions, which is a severe security breach.
- Pen-Input/Stylus: Calculators that require a stylus or pen for input are generally prohibited. This often correlates with more advanced, tablet-like devices that may have other disallowed features or could be used for note-taking in a way that circumvents rules.
- External Devices: Connecting your calculator to external devices like a phone, smartwatch, or any other electronic gadget is strictly forbidden. The calculator must operate independently and not serve as an interface for other prohibited technology.
- Specific Prohibited Models: Beyond general features, the ACT maintains a list of specific calculator models that are explicitly prohibited. These often include older, very powerful models or those known to have features that are difficult to monitor. Examples include the TI-89, TI-92, and HP 48GII. Even if you believe your calculator doesn’t have a prohibited feature, if it’s on this list, it’s not allowed.
Understanding these factors is essential for any student asking, “Am I able to use a graphing calculator on ACT?”
Frequently Asked Questions (FAQ)
Q: Can I use any graphing calculator on the ACT?
A: No, not all graphing calculators are allowed. While many popular models like the TI-84 Plus CE are permitted, calculators with specific prohibited features (e.g., QWERTY keyboards, CAS, wireless communication, cameras, pen-input) or explicitly prohibited models (e.g., TI-89, TI-Nspire CX CAS) are not allowed.
