Use this tool to determine if your calculator or a similar model is likely permitted on the ACT. Keep in mind official ACT guidelines are the final authority.

Eligibility Assessment

Calculation Logic: This assessment evaluates your calculator based on common ACT restrictions. ACT-approved calculators generally include standard, scientific, and most graphing calculators that do NOT have QWERTY keyboards, wireless communication, or advanced symbolic math capabilities. Devices like smartphones, tablets, and laptops are typically NOT allowed. The “Turns On?” and “Built-in Calculator App?” are crucial for basic verification.

What Calculator Can You Use on the ACT? A Comprehensive Guide

A) What is ACT Calculator Policy?

The ACT Calculator Policy dictates the types of electronic devices you can use during the ACT test. The goal is to ensure a fair testing environment by allowing tools that aid in computation but do not provide answers or unauthorized assistance. Understanding these rules is crucial for test-takers to avoid confiscation of devices or disqualification of scores. This guide breaks down the policy and helps you determine if your calculator is ACT-compliant.

Who Should Use This Guide: Any student preparing to take the ACT, especially those who rely on specific calculators or electronic devices for mathematical tasks. This includes students using basic, scientific, graphing, programmable, or even tablet/smartphone-like devices for practice.

Common Misunderstandings: A frequent confusion arises regarding the line between a “calculator” and a “computer.” While many graphing calculators have advanced features, they are generally permitted if they lack communication capabilities and full keyboards. Conversely, devices that can connect to the internet, store vast amounts of data, or run applications beyond basic math functions are typically prohibited.

B) ACT Calculator Policy Explained

The ACT allows most standard, scientific, and graphing calculators. However, there are strict limitations to prevent unfair advantages. The primary restrictions focus on communication, advanced features, and device type.

Core Restrictions:

• No Communication Devices: Calculators that can communicate with other devices (wirelessly or via cables) are banned. This includes calculators with infrared ports, Wi-Fi, Bluetooth, or cellular capabilities.
• No QWERTY Keyboards: Calculators with a full alphabetic (QWERTY) keyboard are not permitted.
• No Advanced Features: Devices with Computer Algebra System (CAS), symbolic math capabilities, equation solvers that can automatically generate answers, or other advanced features that can solve problems for you are prohibited.
• No Laptops, Tablets, or Smartphones: These devices are generally not allowed, even if they have calculator applications. Their functionality extends far beyond that of a permitted calculator.

What IS Generally Allowed:

• Four-function calculators
• Scientific calculators
• Graphing calculators (provided they meet the above restrictions)

Key Considerations:

• “Turning On” Rule: The ACT has a specific rule that if a calculator can turn on and perform a function, it must be cleared of all programs and data. It’s safest to assume any calculator you bring must be in its default, factory-reset state, or have all advanced functions disabled.
• Model Specifics: While the general rules are clear, specific calculator models can sometimes be borderline. It’s always best to check the official ACT website for the most up-to-date list of prohibited models and to consult the ACT if you are unsure about your specific device.

Formula/Logic Summary: The ACT calculator policy can be summarized as allowing computational aids that *assist* with calculations but do not *provide answers* or *facilitate communication*. The underlying logic is to level the playing field and test a student’s mathematical reasoning and problem-solving skills, not their ability to program a device or access external information.

C) Practical Examples

Let’s look at some common calculator scenarios for the ACT.

Example 1: Standard Scientific Calculator

• Inputs:
• Calculator Type: Scientific
• Numeric Keypad: Yes
• QWERTY Keyboard: No
• Power On: Yes
• Wireless Communication: No
• Built-in Calculator App: Yes (as a calculator function)
• Advanced Features: No (standard scientific functions like sin, cos, log)
• Result: Likely Permitted. This is a standard scientific calculator, which is generally allowed on the ACT.
• Reasoning: It has a numeric keypad, no QWERTY keyboard, no wireless communication, and lacks advanced CAS features.
• ACT Guidelines Key Points: Allowed, provided it’s cleared of programs if applicable.

Example 2: Smartphone

• Inputs:
• Calculator Type: Smartphone
• Numeric Keypad: Yes (on-screen)
• QWERTY Keyboard: Yes (on-screen)
• Power On: Yes
• Wireless Communication: Yes (Wi-Fi, Cellular)
• Built-in Calculator App: Yes
• Advanced Features: Yes (potentially, plus general computing power)
• Result: Not Permitted.
• Reasoning: Smartphones are explicitly banned due to their communication capabilities, QWERTY keyboard, and general-purpose computing nature, even if they have a calculator app.
• ACT Guidelines Key Points: Banned as a communication device and general-purpose computer.

Example 3: Graphing Calculator with USB Port

• Inputs:
• Calculator Type: Graphing Calculator
• Numeric Keypad: Yes
• QWERTY Keyboard: No
• Power On: Yes
• Wireless Communication: No (but has USB)
• Built-in Calculator App: Yes
• Advanced Features: No (standard graphing functions)
• Result: Likely Permitted (with caution).
• Reasoning: While it lacks wireless communication and QWERTY, the presence of a USB port could be interpreted as a communication capability by some proctors. ACT policy states “Calculators that have computer algebra system (CAS) or symbolic math features… are not permitted.” and “Calculators that have telephone or pager functions, or that have a speaker or an eraseable pilot light, or that wirelessly communicate with other calculators or electronic devices are not permitted.” If the USB port is solely for data transfer between the calculator and a computer (not direct communication during the test), it might be allowed. However, ACT advises against calculators with such ports if they can communicate. The safest bet is to use a model without one.
• ACT Guidelines Key Points: Ensure no communication features (even USB if interpreted as such) and no CAS.

E) Key Factors That Affect ACT Calculator Permissibility

1. Device Type: The fundamental classification (phone, tablet, laptop vs. dedicated calculator) is the first filter.
2. Communication Capabilities: Any form of wireless or wired communication is a primary disqualifier. This is the most significant restriction.
3. Keyboard Layout: The presence of a full QWERTY keyboard automatically disqualifies a device.
4. Advanced Mathematical Functions: Calculators with CAS, symbolic manipulation, or automatic equation solvers are prohibited. The ACT tests your ability to calculate, not to have an external system solve problems for you.
5. Programmability: While not explicitly banned in all cases, heavily programmable calculators can sometimes be flagged if their programs enable prohibited functions (like CAS). ACT advises clearing all programs.
6. Power On & Default State: The rule that any calculator must turn on and be cleared of programs means that even compliant models must be used responsibly. A malfunctioning calculator or one loaded with forbidden apps could still be an issue.
