What Calculators Can You Use For The Act

Use this tool to check if your calculator is likely permitted on the ACT based on the official ACT calculator policy. Find out what calculators you can use for the ACT.

Check Your Calculator’s ACT Eligibility

This checker uses the official ACT calculator policy guidelines. It checks for prohibited features like QWERTY keyboards, CAS (with exceptions), wireless communication, power requirements, and integration with other devices.

What is the ACT Calculator Policy?

The ACT calculator policy outlines the rules and regulations regarding the types of calculators students are permitted to use during the ACT test, particularly the mathematics section. The policy is designed to ensure fairness and prevent any student from having an unfair advantage through the use of unauthorized aids. Knowing what calculators you can use for the ACT is crucial for test day.

Students taking the ACT are generally allowed to use a calculator on the mathematics test, but not all calculators are permitted. The ACT calculator policy specifies features and models that are prohibited. It’s essential for students to check the latest policy on the official ACT website before test day, as it can be updated. Understanding what calculators you can use for the ACT helps you prepare adequately.

Who Should Understand the ACT Calculator Policy?

All students planning to take the ACT, their parents, and educators should be familiar with the ACT calculator policy. Familiarity ensures students bring an approved device and are not disadvantaged or disqualified on test day. Understanding what calculators you can use for the ACT is part of test preparation.

Common Misconceptions

• “All graphing calculators are allowed”: This is false. Many graphing calculators with Computer Algebra Systems (CAS) are prohibited.
• “You don’t need a calculator for the ACT math”: While the math test can be completed without a calculator, using an allowed calculator efficiently can save time and help with complex calculations.
• “The policy is the same every year”: The ACT can update its calculator policy, so always check the most current version.

ACT Calculator Policy Rules Explained

The ACT calculator policy is based on identifying and prohibiting calculators with features that could provide an unfair advantage. Here’s a breakdown:

• Prohibited Features:
  • Calculators with built-in or add-on QWERTY (typewriter-like) keypads.
  • Calculators that are part of cell phones, smartphones, tablets, laptops, or other electronic communication devices.
  • Calculators that use wireless, Bluetooth, or infrared communication.
  • Calculators that require an electrical outlet, make noise, or have a paper tape.
  • Calculators with a Computer Algebra System (CAS), unless specifically allowed with modifications (which is rare and complex for ACT). Models like TI-89, TI-92, and TI-Nspire CAS are usually prohibited.
• Allowed Calculators (Generally):
  • Basic four-function calculators.
  • Scientific calculators (without prohibited features).
  • Graphing calculators (without CAS or other prohibited features, e.g., TI-83, TI-84 series, TI-Nspire non-CAS).
• Memory and Programs: Calculators with memory that can store programs or documents are usually allowed, BUT you are responsible for clearing any prohibited content before the test. This includes test-specific programs or notes.

Always refer to the official ACT website for the definitive and most up-to-date ACT calculator policy and the list of what calculators you can use for the ACT.

Practical Examples (Real-World Use Cases)

Example 1: Checking a TI-84 Plus

A student has a TI-84 Plus graphing calculator.
Inputs to Checker:

• Type: Graphing
• QWERTY: No
• CAS: No (standard TI-84 Plus doesn’t have CAS)
• Outlet: No
• Wireless: No
• Noise/Print: No
• Device: No
• Memory: Yes (has program memory)

Result: Allowed with Modifications (Memory needs to be cleared of any non-permitted programs/data before the test).

Example 2: Checking a TI-Nspire CX CAS

A student has a TI-Nspire CX CAS.
Inputs to Checker:

• Type: Graphing with CAS
• QWERTY: No
• CAS: Yes
• Outlet: No
• Wireless: No
• Noise/Print: No
• Device: No
• Memory: Yes

Result: Prohibited (Due to the CAS feature, which is generally not allowed).

How to Use This ACT Calculator Policy Checker

1. Select Calculator Type: Choose the general category of your calculator from the dropdown.
2. Answer Feature Questions: Respond “Yes” or “No” to the questions about your calculator’s specific features (QWERTY, CAS, etc.).
3. Check Results: The tool will display “Allowed,” “Prohibited,” or “Allowed with Modifications” based on your inputs and the current ACT calculator policy guidelines.
4. Review Reasons: Look at the “Reasons / Considerations” list for details on why your calculator received that status.
5. Consult Official Policy: Always double-check with the latest official ACT calculator policy on the ACT website, especially for specific models or if you are unsure. Knowing what calculators you can use for the ACT is your responsibility.

Key Factors That Affect ACT Calculator Eligibility

• Computer Algebra System (CAS): Calculators with CAS can perform symbolic algebra, which is generally not allowed on the ACT. This is a major factor for prohibition.
• QWERTY Keyboard: Any calculator with a typewriter-like keyboard is strictly forbidden.
• Communication Capabilities: Wireless, Bluetooth, or infrared features are prohibited to prevent communication during the test.
• Power Source: Calculators must be battery-operated. Those needing an external power source are not allowed.
• Integration with Other Devices: Calculators built into phones, watches, or laptops are not permitted.
• Stored Content: While calculators with memory are allowed, programs or documents that give an unfair advantage must be cleared.
• Noise or Printing: Calculators that make noise or print are disruptive and not allowed.
• Official Prohibited List: The ACT website may list specific models that are prohibited, even if they don’t obviously fit the feature-based rules.

Frequently Asked Questions (FAQ)

1. Is the TI-84 Plus allowed on the ACT?

Yes, the TI-84 Plus and TI-84 Plus CE are generally allowed as they do not have CAS, but you must clear the memory of prohibited programs or data.

2. Is the TI-Nspire CX CAS allowed on the ACT?

No, the TI-Nspire CX CAS is generally prohibited because of its Computer Algebra System (CAS). The non-CAS version (TI-Nspire CX) is usually allowed.

3. What happens if I bring a prohibited calculator to the ACT?

If you are found with a prohibited calculator, it will be confiscated, and you may not be allowed to test, or your scores could be invalidated. It’s crucial to understand the ACT calculator policy.

4. Can I use my phone as a calculator?

No, phones, smartwatches, or any device with communication capabilities are strictly prohibited.

5. Do I need to clear the memory of my allowed calculator?

Yes, if your calculator can store programs or documents, you are responsible for removing any content that violates the ACT calculator policy before the test.

6. Where can I find the official ACT calculator policy?

You can find the most up-to-date policy on the official ACT website (act.org). Always check there before your test date for the latest information on what calculators you can use for the ACT.

7. Are there any calculators recommended for the ACT?

While the ACT does not endorse specific brands, many students use graphing calculators like the TI-84 series or scientific calculators. The best calculator is one you are familiar with and that complies with the ACT calculator policy.

8. What if my calculator has games on it?

Games, like other programs and documents not originally part of the calculator’s standard functionality or those providing an unfair advantage, must be removed before the test.
