Do You Get A Calculator On The Act

An essential tool to verify your calculator’s compliance with the official ACT test day policy.

What is the ACT Calculator Policy?

The question, “do you get a calculator on the ACT,” is a critical one for test-takers. The simple answer is yes, but only on the Mathematics Test section, and only if your calculator is on the approved list. The ACT has a detailed policy to ensure fairness and test security. Not all calculators are created equal in the eyes of the test administrators. Calculators with certain features, like a Computer Algebra System (CAS), are strictly forbidden. You are responsible for bringing an approved device; testing centers will not provide one.

Understanding the nuances of what is and isn’t allowed is key to avoiding issues on test day. Even some permitted calculators require modifications, such as covering an infrared data port or removing paper tape. Familiarizing yourself with these rules is as important as your math preparation.

ACT Calculator Formula and Explanation

While there isn’t a mathematical formula to determine if a calculator is allowed, the decision process can be thought of as a logical check against a set of rules. The “formula” is a series of conditions your device must meet.

Primary Rule: The device must NOT be on the prohibited list and must NOT have prohibited functionality (like CAS or a QWERTY keyboard).

Prohibited vs. Permitted Features

Feature / Type	Status	Explanation
Computer Algebra System (CAS)	Prohibited	These systems can solve algebraic equations, which is not allowed. Models like the TI-89 and HP Prime are banned for this reason.
QWERTY Keyboard	Prohibited	Calculators with a lettered keyboard like a computer are not permitted.
Graphing Capabilities	Permitted	Most graphing calculators (like the TI-84 series) are allowed, as long as they don’t have CAS.
Scientific Calculator	Permitted	These are generally safe and provide all the necessary functions for the ACT.
Programs / Apps	Requires Check	You must remove any documents and any programs that add CAS functionality.
Infrared Port	Requires Modification	The port must be completely covered with opaque tape.

Practical Examples of Calculator Checks

Example 1: A Permitted Calculator

• Input: TI-84 Plus CE
• Analysis: This model is a standard graphing calculator and does not have a built-in CAS. It’s one of the most common and widely accepted calculators.
• Result: Allowed. The TI-84 Plus series is explicitly mentioned as a permitted line of calculators.

Example 2: A Prohibited Calculator

• Input: TI-89 Titanium
• Analysis: This model is well-known for its powerful Computer Algebra System (CAS), which is explicitly on the ACT’s prohibited features list.
• Result: Prohibited. All models that begin with TI-89 or TI-92 are banned.

How to Use This ACT Calculator Checker

Using this tool is straightforward and can save you from a major headache on test day. Follow these simple steps:

1. Find Your Calculator’s Model Name: Look at the front, back, or inside cover of your calculator. You should see a model name and number, such as “TI-30XS MultiView” or “HP 50G”.
2. Enter the Model Name: Type the full model name into the input field above.
3. Check the Result: Click the “Check My Calculator” button. The tool will analyze your input and provide one of three results: Allowed, Prohibited, or Check Details.
4. Read the Details: The result will give you a clear status and explain why your calculator is or isn’t allowed, referencing the official ACT policy.

Key Factors That Affect Calculator Legality

When determining if you get a calculator on the ACT, several factors come into play. Understanding them helps you choose the right tool.

• Computer Algebra System (CAS): This is the number one feature that gets a calculator banned. It automates solving complex algebra.
• Communication Ability: Any device that can communicate wirelessly (e.g., via Wi-Fi, Bluetooth, or infrared) is prohibited or requires modification.
• Power Source: Calculators needing an electrical outlet are not allowed. Your device must be battery-powered.
• Keyboard Style: A QWERTY keyboard is an immediate disqualifier.
• Noise and Printing: Calculators that make noise must be muted, and those with a paper tape must have the tape removed.
• Stored Information: While you can have programs, you cannot have saved documents or notes on your calculator. Proctors may check and clear your device’s memory.

Frequently Asked Questions (FAQ)

Do you get a calculator on the act for all sections?

No. Calculators are only permitted for the Mathematics Test. You cannot use a calculator on the English, Reading, or Science sections.

What happens if I bring a prohibited calculator?

If testing staff find you with a prohibited calculator, you may be dismissed from the test, and your score will be voided.

Is the TI-Nspire allowed on the ACT?

It depends. The standard TI-Nspire and TI-Nspire CX models are allowed. However, the TI-Nspire CAS and TI-Nspire CX II-T CAS models are strictly prohibited. You must check that your version does not have “CAS” in its name.

Do I need a graphing calculator for the ACT?

No, all math problems on the ACT can be solved without a calculator. However, a familiar graphing or scientific calculator can be a powerful tool to save time and verify answers. A basic 4-function calculator is generally not sufficient.

Can I share my calculator with a friend?

No. Sharing calculators during the test is not permitted under any circumstances.

Should I bring a backup calculator?

Yes, it’s a great idea. Bringing a backup calculator and extra batteries is recommended in case your primary one fails.

Are calculator apps on phones or smartwatches allowed?

Absolutely not. Cell phones, smartwatches, laptops, and any other personal electronic devices with communication capabilities are banned from the testing room.

What does ‘modifying’ a calculator mean?

For certain older but powerful calculators, like some HP models with infrared ports, you must cover the port with opaque tape. If your calculator can print, you must remove the paper roll.
