ACT Graphing Calculator Policy Checker

Use this tool to determine if your graphing calculator meets the ACT’s requirements.

What is the ACT Graphing Calculator Policy?

The ACT, a standardized test widely used for college admissions in the United States, has specific rules regarding the types of calculators permitted during the exam. The primary goal of these regulations is to ensure a fair testing environment by preventing students from using devices that offer unfair advantages. This policy mainly targets calculators with advanced functionalities that go beyond basic mathematical computations, such as those with communication capabilities, extensive memory storage for unauthorized content, or features that mimic computer operations.

Understanding the ACT calculator policy is crucial for all test-takers, especially those who rely on graphing or scientific calculators for the Math and Science sections. Failure to comply can result in your calculator being confiscated or your test score being invalidated. This checker helps you navigate these rules by assessing whether your specific calculator model likely meets the ACT’s criteria.

Who should use this checker?

• Students preparing for the ACT.
• Anyone who owns a graphing or advanced scientific calculator and is unsure about its permissibility.
• Educators and parents seeking to guide students on ACT test day preparation.

Common Misunderstandings: A frequent misconception is that all graphing calculators are banned. While many advanced models are indeed prohibited, the ACT does permit a wide range of standard graphing and scientific calculators. The key is understanding the *specific features* that are disallowed, rather than the calculator type itself. For example, a TI-84 Plus is generally allowed, but if it’s been modified with unauthorized programs, it could be confiscated.

ACT Calculator Policy: Rules and Explanation

The ACT’s calculator policy can be summarized by a few key prohibitions. Calculators are generally permitted if they are standard 4-function, scientific, or graphing calculators that do not have any of the following features:

• QWERTY Keyboard: Calculators with a full or partial QWERTY (typewriter-style) keyboard are prohibited. This is to prevent their use as a text storage device.
• Wireless Connectivity: Devices that can communicate with other calculators or devices via wireless technology (e.g., Bluetooth, Wi-Fi, infrared) are banned.
• Bidirectional Communication: Calculators that allow two-way data transfer between devices are not allowed.
• Computer-Like Functions: Devices with capabilities such as typing text, storing and retrieving files (like PDFs or documents), or accessing the internet are prohibited.
• Stored Formulas or Programs: While standard scientific and graphing functions are permitted, storing unauthorized programs or complex formulas that could provide an unfair advantage is disallowed. ACT specifically mentions that calculators with any functions that the test center supervisor deems inappropriate are banned.

The ACT Calculator Policy Formula (Conceptual):

IsCalculatorAllowed = (Standard Functions Allowed) AND NOT (QWERTY Keyboard OR Wireless Connectivity OR Bidirectional Communication OR Computer-Like Functions OR Unauthorized Stored Programs)

ACT Calculator Policy Variables

Variable	Meaning	Unit / Type	Typical Range / Allowed Values

QWERTY Keyboard	Presence of a typewriter-style keyboard.	Boolean (Yes/No)	No
Wireless Connectivity	Ability to send/receive data wirelessly.	Boolean (Yes/No)	No
Bidirectional Communication	Ability to exchange data with other devices.	Boolean (Yes/No)	No
Computer-Like Functions	Advanced features beyond calculation (e.g., text editing, file storage).	Boolean (Yes/No)	No
Unauthorized Stored Programs	Pre-loaded or user-added programs giving an unfair advantage.	Boolean (Yes/No)	No

Note: The ACT website provides a list of approved and prohibited calculators. It’s always best to consult this official list.

Practical Examples of Calculator Eligibility

Let’s look at a couple of common scenarios to illustrate the ACT’s calculator policy:

Example 1: Texas Instruments TI-84 Plus

• Calculator Model: TI-84 Plus
• QWERTY Keyboard: No
• Wireless Connectivity: No (standard model)
• Bidirectional Communication: No (standard model, though some older versions might have had link ports, these are typically not considered wireless)
• Computer-Like Functions: No (standard functions only)
• Stored Formulas/Programs: No (standard functions, no unauthorized programs)
• Result: Likely Allowed. The TI-84 Plus is a widely accepted graphing calculator for the ACT, provided no unauthorized programs are loaded onto it.

Example 2: Casio PRIZM fx-CG50

• Calculator Model: Casio PRIZM fx-CG50
• QWERTY Keyboard: No
• Wireless Connectivity: No (standard model)
• Bidirectional Communication: No (standard model)
• Computer-Like Functions: No (standard functions, including graphing and basic programming)
• Stored Formulas/Programs: No (standard functions, no unauthorized programs)
• Result: Likely Allowed. This model offers advanced graphing capabilities but adheres to the ACT’s restrictions on prohibited features.

Example 3: HP Prime Graphing Calculator

• Calculator Model: HP Prime
• QWERTY Keyboard: No
• Wireless Connectivity: Yes (has Wi-Fi capability)
• Bidirectional Communication: No (standard model)
• Computer-Like Functions: No (standard functions)
• Stored Formulas/Programs: No (standard functions)
• Result: Prohibited due to Wi-Fi. Even though it’s a powerful graphing calculator, its wireless connectivity feature makes it ineligible for use on the ACT. The Wi-Fi must be disabled, or a different calculator should be used.

How to Use This ACT Graphing Calculator Checker

1. Identify Your Calculator Model: Find the exact name and model number of your calculator (e.g., “Texas Instruments TI-84 Plus CE”, “Casio fx-CG 20”).
2. Input Details: Enter the model name into the “Calculator Model/Name” field.
3. Answer Feature Questions: Carefully answer the questions about your calculator’s features:
   • Does it have a QWERTY keyboard?
   • Can it connect wirelessly (Wi-Fi, Bluetooth)?
   • Can it communicate bidirectionally with other calculators?
   • Does it have computer-like functions (internet, file storage, word processing)?
   • Does it store unauthorized programs or advanced formulas?

   Select “Yes” or “No” for each based on your calculator’s capabilities. For the “Model Allowed by Default” and “Stored Formulas/Programs”, use your best judgment. If unsure, assume “Yes” for features that might be borderline or prohibited.

Key Factors That Affect ACT Calculator Allowance

Beyond the core prohibitions, several nuances can influence whether a calculator is permitted on the ACT:

1. Firmware Updates: Manufacturers sometimes release firmware updates that can add or change features. An older version of a calculator might be allowed, while an updated version of the same model could become prohibited due to new features (e.g., added wireless capability).
2. Third-Party Software/Programs: Loading unauthorized applications, scripts, or advanced mathematical programs onto a calculator can render it ineligible, even if the base hardware is compliant. ACT aims to prevent any form of electronic assistance beyond basic computation.
3. Test Center Discretion: Ultimately, the ACT test center supervisor has the authority to disallow any calculator they deem inappropriate, regardless of official guidelines. This is a safety net to ensure fairness.
4. Model Variations: Sometimes, different versions or sub-models within a product line can have varying features. For example, a “Plus” version might be allowed, while a “Pro” or “Wireless” version of the same base model might not be.
5. Physical Modifications: Any physical alteration to the calculator, such as attempts to add hardware or remove components, would certainly make it ineligible.
6. Derivative Calculators: Calculators that are essentially data storage devices or that can be easily reprogrammed to store vast amounts of text or information are highly likely to be banned.

FAQ: ACT Calculator Policy

1. Q: Can I use my TI-89 on the ACT?
   A: The TI-89 is generally prohibited because it has advanced symbolic math capabilities and a design that leans towards computer-like functions. Always check the official ACT list, but expect it to be disallowed.
2. Q: Is a TI-Nspire CX CAS allowed?
   A: The TI-Nspire CX CAS (Computer Algebra System) version is typically prohibited due to its advanced CAS features. The non-CAS TI-Nspire models might be allowed, but it’s crucial to verify the specific model and ensure all prohibited features are disabled.
3. Q: What if my calculator has a USB port?
