ACT® Calculator Policy Tool
Check Your Calculator’s ACT® Eligibility
Enter your calculator’s model name to check if it’s likely permitted on the ACT. This tool checks your input against the official ACT calculator policy. For a definitive answer, always consult the official ACT website.
Figuring out **what calculator is allowed on the ACT** is a critical step in your test day preparation. The ACT has a specific calculator policy designed to ensure fairness and prevent academic dishonesty. Using a prohibited device can lead to your scores being canceled. This guide provides a detailed overview of the rules and includes a helpful calculator to check your model. Knowing the policy helps you choose the right tool so you can focus on the math section with confidence.
What is the ACT Calculator Policy?
The ACT calculator policy outlines which calculators are permitted and which are prohibited for use on the mathematics portion of the ACT test. You are allowed to use a calculator only on the math test. All problems can be solved without a calculator, but using a familiar and permitted calculator can significantly improve your speed and accuracy. The core of the policy is to ban devices with functionalities that give an unfair advantage, such as Computer Algebra Systems (CAS), wireless communication, or QWERTY keyboards. Understanding **what calculator is allowed on the ACT** is the student’s responsibility, not the testing staff’s.
This policy is crucial for maintaining a standardized testing environment. Any four-function, scientific, or graphing calculator is generally allowed as long as it’s not on the prohibited list. However, some calculators may require modifications, like covering an infrared port. The question of **what calculator is allowed on the ACT** is therefore not just about specific models, but also about specific features.
The ACT’s Evaluation Logic: Prohibited Features
The ACT doesn’t approve specific calculators; instead, it prohibits specific features. If your calculator has any of the following, it is NOT allowed. This logic is central to determining **what calculator is allowed on the ACT**. The most significant prohibited feature is a Computer Algebra System (CAS).
| Feature/Category | Description | Examples of Prohibited Models | Required Action |
|---|---|---|---|
| Computer Algebra System (CAS) | Calculators that can solve algebraic equations symbolically. | TI-89, TI-92, TI-Nspire CAS, HP Prime, Casio ClassPad series. | Cannot be used, even if CAS is disabled. |
| QWERTY Keyboard | Calculators with a lettered keyboard in the typical typewriter layout. | Devices with built-in keyboards. | Cannot be used. |
| Communication Devices | Calculators with wireless, Bluetooth, or cellular capability. Phones, tablets, and laptops. | All smart devices. | Cannot be used. |
| Infrared Data Port | Ability to transfer data wirelessly via infrared. | HP 38G Series, HP 39G Series, HP 48G. | Must be completely covered with opaque tape. |
| Paper Tape or Noise | Calculators that print to a paper roll or make sounds. | Various printing or talking calculators. | Remove tape; turn off sound. |
ACT Calculator Decision Flowchart
Practical Examples
Let’s look at two common scenarios to clarify **what calculator is allowed on the ACT**.
Example 1: Texas Instruments TI-84 Plus CE
A student wants to use their TI-84 Plus CE. They enter “TI-84 Plus CE” into the checker. The tool recognizes this is not on the prohibited list and does not have a CAS. The result is “Allowed.” The student knows they can bring this popular graphing calculator to the test.
Example 2: Texas Instruments TI-89 Titanium
Another student has a TI-89 Titanium, a powerful calculator. They enter “TI-89” into the checker. The tool immediately flags this model because all calculators beginning with “TI-89” are explicitly banned due to their built-in CAS. The result is “Prohibited,” and the student knows they need to find an alternative calculator for the exam.
How to Use This ACT Calculator Checker
Using this tool to determine **what calculator is allowed on the ACT** is simple:
- Enter Model Name: Type the model of your calculator into the input field. Be as specific as possible.
- Check Eligibility: Click the “Check Eligibility” button.
- Review Results: The tool will provide one of three results: Allowed, Prohibited, or Check Details (for models that may require modification).
- Read the Details: The sections below the main result give you the reason for the status and any actions you need to take.
Key Factors That Affect What Calculator is Allowed on the ACT
Several factors determine a calculator’s eligibility. Understanding these is key to knowing **what calculator is allowed on the ACT** for your test day.
- Computer Algebra System (CAS): This is the most common reason for a calculator being prohibited. CAS-equipped calculators can perform symbolic manipulation, which is a banned function.
- QWERTY Keyboard: Any device with a typewriter-style keyboard is not allowed.
- Communication Technology: Calculators cannot have any form of wireless communication (e.g., Wi-Fi, Bluetooth, Infrared). If an infrared port is present, it must be covered.
- Power Source: Calculators needing an electrical outlet are not allowed. Bring fresh batteries or a backup.
- Programs and Documents: While many graphing calculators can store programs, any programs that have CAS functionality must be removed. It’s safest to clear the memory before the test.
- Physical Modifications: Some calculators are only allowed if modified. This includes removing paper tape, muting sound, and covering data ports.
Frequently Asked Questions (FAQ)
Yes, most graphing calculators are allowed, provided they do not have a Computer Algebra System (CAS). Models like the TI-84 Plus and TI-Nspire (non-CAS) are perfectly acceptable.
The TI-Nspire (non-CAS) model is allowed. However, the TI-Nspire CAS model is strictly prohibited. You must check which version you have.
If you are found using a prohibited calculator during the test, you may be dismissed from the testing center, and your test will be voided. This is why checking **what calculator is allowed on the ACT** beforehand is so important.
The ACT requires that you remove any documents and programs that have CAS functionality. To be safe, it is highly recommended to clear your calculator’s memory before the test.
No, sharing calculators is not permitted during the test under any circumstances.
The “best” calculator is one you are familiar and comfortable with. A powerful graphing calculator is useless if you don’t know how to operate it. Many students succeed with a reliable scientific calculator like the TI-30XS.
Yes, all standard scientific calculators are allowed. They are a great choice for students who don’t need graphing capabilities.
Absolutely not. Cell phones, tablets, smartwatches, or any other communication devices are banned from the testing room.
