What is the ACT Calculator Policy?

The ACT calculator policy outlines the rules regarding which calculators are permitted for use during the mathematics portion of the ACT exam. While all math problems on the ACT can be solved without a calculator, using an approved one can significantly improve speed and accuracy. The fundamental question for many students is, **can you use the calculator on the act**? The answer is yes, but only on the math section, and only if your device complies with a strict set of guidelines designed to ensure fairness and prevent academic dishonesty.

This policy is for all test-takers. It’s crucial to understand these rules because showing up with a prohibited device can lead to its confiscation or even dismissal from the test. Common misconceptions include thinking any graphing calculator is fine, or that the rules are the same as for the SAT. However, the ACT has its own specific list of banned devices and features.

How the ACT Determines Calculator Eligibility

The ACT’s “formula” for determining if a calculator is allowed is a logical process based on a series of feature checks. The goal is to eliminate any device that could provide an unfair advantage, such as by solving algebraic equations automatically (CAS), accessing the internet (wireless), or having a computer-like interface (QWERTY). Understanding if **can you use the calculator on the act** depends entirely on these features.

Table of Features and Their ACT Policy Status

Feature (Variable)	Meaning	Status on ACT	Typical Example
Device Type	Is the calculator a standalone device?	Only dedicated handheld calculators allowed.	Phones, tablets, laptops are PROHIBITED.
QWERTY Keyboard	A full keyboard layout like a computer.	PROHIBITED.	Calculators with letter keys for typing.
Computer Algebra System (CAS)	Can perform algebraic manipulations and solve variables.	PROHIBITED.	TI-89, TI-Nspire CAS, HP Prime.
Wireless Communication	Wi-Fi, Bluetooth, or any internet/data capability.	PROHIBITED.	Any device that can connect to other devices or networks.
External Power	Requires a wall outlet to function.	PROHIBITED.	Calculators with power cords.
Paper Tape / Printer	Ability to print calculations.	ALLOWED only if tape is removed.	Printing calculators.

Practical Examples (Real-World Use Cases)

Example 1: The Standard Permitted Calculator

• Calculator Model: Texas Instruments TI-84 Plus
• Feature Analysis: No QWERTY keyboard, no CAS, no wireless. It is a standard graphing calculator widely accepted.
• Verdict: PERMITTED. This is one of the most common and recommended calculators for the ACT.

Example 2: The Prohibited High-End Calculator

• Calculator Model: Texas Instruments TI-89 Titanium
• Feature Analysis: This calculator includes a built-in Computer Algebra System (CAS), which is explicitly banned.
• Verdict: PROHIBITED. The ability to solve algebraic equations makes it an unfair advantage according to the policy.

How to Use This ACT Calculator Policy Checker

Using this tool to determine if **can you use the calculator on the act** is straightforward:

1. Review Your Calculator: Look at your calculator and identify its features.
2. Check the Boxes: For each question in the calculator section above, check the box if your calculator has that specific feature.
3. Review the Result: The tool will instantly display “PERMITTED” or “PROHIBITED”. If prohibited, the “Key Reasons” section will list exactly which features violate the ACT policy.
4. Reset and Compare: Use the “Reset” button to clear the selections and test another calculator model.

Key Factors That Affect Calculator Permissibility

Several key factors determine whether you can use a calculator on the ACT. Being aware of these will ensure you arrive on test day with an approved device.

• Computer Algebra System (CAS): This is the most common reason for a graphing calculator to be banned. CAS can symbolically solve expressions, which is not allowed.
• QWERTY Keyboards: Any calculator with a keyboard layout like a computer’s is strictly forbidden.
• Communication Devices: Calculators built into phones, tablets, or any device with wireless capability are prohibited.
• Need for an Outlet: If your calculator needs to be plugged in, it’s not allowed. It must be battery-operated.
• Modifications Required: Some calculators are allowed only with modifications. For instance, those with infrared data ports must have the port covered with opaque tape. Calculators that make noise must be muted.
• Prohibited List: The ACT publishes a specific list of banned models, such as the TI-89, TI-92, and HP Prime series. It’s always best to check this list.

Frequently Asked Questions (FAQ)

1. Can I use a calculator on all sections of the ACT?

No, calculators are only permitted during the Mathematics section of the ACT. Use during the English, Reading, or Science sections is prohibited.

2. What happens if I’m caught with a prohibited calculator?

Test staff will likely confiscate the calculator, and you may be dismissed from the test, with your score being voided.

3. Is the TI-Nspire allowed?

The TI-Nspire (non-CAS) model is permitted. However, the TI-Nspire CAS model is strictly prohibited.

4. Do I need to clear my calculator’s memory?

You must remove any programs that have CAS functionality and any stored documents. Programs for solving specific math problems or games are also not recommended, as proctors may check.

5. Can I share my calculator with another student?

No, sharing calculators is not permitted under any circumstances.

6. What if my calculator’s batteries die during the test?

You are responsible for ensuring your calculator works. It’s highly recommended to install fresh batteries before the test. You can bring a backup calculator and extra batteries, but they must be kept away unless your primary one fails.

7. Are all scientific calculators allowed?

Generally, yes. Nearly all standard scientific calculators are permitted as they do not have the advanced prohibited features like CAS or QWERTY keyboards. Models like the TI-30XS are very safe choices.

8. Is knowing **can you use the calculator on the act** the most important thing?

While knowing the rules is critical, it is equally important to be familiar with the calculator you bring. Practice with your approved calculator so you can use it quickly and efficiently on test day.
