Calculators You Can Use On The Act In Nevada

Determine if your calculator is one of the calculators you can use on the ACT in Nevada based on the official 2025-2026 test year rules.

Check Your Calculator’s Eligibility

Status: N/A

Reasoning: N/A

General Policy: The ACT allows most 4-function, scientific, and graphing calculators that are not on the prohibited list.

What are the calculators you can use on the ACT in Nevada?

The policy for calculators you can use on the ACT in Nevada is identical to the national ACT calculator policy. There are no state-specific rules for Nevada. [2] The ACT organization sets forth guidelines to ensure fairness and test security for all students. You are allowed to use a calculator only on the Mathematics Test section. [2] It’s crucial to understand these rules because using a prohibited device can lead to dismissal from the test center and cancellation of your scores. [4]

Essentially, any 4-function, scientific, or graphing calculator is permitted as long as it’s not on the official prohibited list and doesn’t have forbidden features like a Computer Algebra System (CAS). [5] Students are responsible for bringing their own approved calculator; testing staff will not provide them. This guide and calculator checker are designed to help you determine if your device is one of the approved calculators you can use on the ACT in Nevada.

Common Misconceptions

A frequent misconception is that more expensive or powerful calculators are always better for the test. However, many high-end calculators (like the TI-89 or HP Prime) are banned specifically because they have CAS functionality. [5] Another error is assuming the rules for the SAT and ACT are the same; they are not. [5] Always check the specific ACT policy. Lastly, remember that while a calculator is a useful tool, every problem on the ACT Math Test can be solved without one. [3]

ACT Calculator Rules and Logic Explained

The “formula” for determining if a calculator is allowed isn’t a mathematical equation but a set of logical rules. The policy explicitly prohibits certain models and features. The most critical prohibited feature is a Computer Algebra System (CAS), which can solve algebraic equations symbolically. This is why models like the TI-Nspire CAS are banned, while the non-CAS version of the TI-Nspire is allowed. [3]

Prohibited Features and Rules Table

Key Prohibited Features for ACT Calculators

Feature/Rule	Meaning	Status	Typical Range / Common Examples
Computer Algebra System (CAS)	System that can manipulate and solve algebraic expressions symbolically.	Prohibited	TI-89, TI-92, TI-Nspire CAS, HP Prime, HP 48GII, Casio ClassPad series [5]
QWERTY Keyboard	A keyboard with keys in the standard typewriter layout.	Prohibited	Calculators that look like a small computer or phone.
Wireless Communication	Infrared, Bluetooth, Wi-Fi, or any data transfer capability.	Prohibited	Some older HP models have infrared ports that must be taped over. [3]
Pen-Input / Stylus	Devices operated with a stylus or electronic writing pad.	Prohibited	Tablets, PDAs (Note: Sharp EL-9600 is an exception and is permitted). [2]
External Power	Calculators that need to be plugged into an electrical outlet.	Prohibited	Must be battery-operated. [2]
Makes Noise or Prints	Calculators with audible key tones or a paper tape printer.	Requires Modification	Sound must be turned off; paper tape must be removed. [3]

Practical Examples (Real-World Use Cases)

Example 1: The Standard Graphing Calculator

• Input (Model): TI-84 Plus CE
• Analysis: The TI-84 Plus series is explicitly allowed. It is a graphing calculator but does not have a built-in Computer Algebra System (CAS). It does not have a QWERTY keyboard or any communication features.
• Output (Result): Permitted. This is one of the most common and recommended calculators you can use on the ACT in Nevada.

Example 2: The Prohibited Advanced Calculator

• Input (Model): TI-89 Titanium
• Analysis: The model number “TI-89” is on the ACT’s official prohibited list. This is because the calculator includes a powerful Computer Algebra System (CAS), giving a student an unfair advantage by solving complex algebra for them.
• Output (Result): Prohibited. Despite being a powerful tool, it is not one of the calculators you can use on the ACT in Nevada. You must bring a different device.

How to Use This ACT Calculator Policy Calculator

Using this tool to check for calculators you can use on the ACT in Nevada is straightforward. Follow these steps:

1. Select the Brand: Choose your calculator’s brand (e.g., Texas Instruments, Casio) from the dropdown menu.
2. Enter the Model: Type the model number exactly as it appears on the front of your calculator into the text field.
3. Review the Result: The tool will instantly provide a status: Permitted, Prohibited, or Requires Modification.
4. Read the Details: The intermediate values will give you the reasoning behind the status, helping you understand which specific rule applies to your device.

This process provides a quick and reliable check, giving you peace of mind before test day. For more test day tips, see our guide to your complete ACT test day checklist.

Key Factors That Affect Calculator Eligibility

Understanding these factors is key to knowing which calculators you can use on the ACT in Nevada.

1. Computer Algebra System (CAS):

This is the number one disqualifier. A CAS can perform symbolic algebra, like factoring polynomials or solving for variables. This is considered an unfair advantage. If you’re considering a prep course, our ACT prep course reviews can help you master the concepts yourself.

2. QWERTY-style Keyboard:

Any calculator with a keyboard like a computer’s is banned to prevent the use of devices with text-saving capabilities. [2]

3. Communication Capabilities:

Calculators with infrared ports, Bluetooth, or Wi-Fi are strictly forbidden to prevent cheating. Some older models are allowed if the port is completely covered with opaque tape. [3]

4. Physical Modifications Required:

Some devices are only allowed if modified. This includes removing paper tape, silencing any noise features, or covering an infrared data port. [4]

5. Power Source:

Calculators needing a power cord are not allowed. You must use a battery-powered device and it is wise to bring extra batteries. [4]

6. Digital vs. Paper Test Format:

For the digital ACT, a built-in Desmos calculator is provided on-screen. However, you are still permitted to bring your own approved handheld calculator if you prefer. [6] Understanding the changes in the digital ACT format is crucial.

Frequently Asked Questions (FAQ)

1. Are there specific calculator rules just for Nevada?

No, the ACT has a single, national policy that applies to all states, including Nevada. The rules for calculators you can use on the ACT in Nevada are the same as in any other state. [2]

2. What happens if I bring a prohibited calculator?

Test proctors will check calculators. If you are found with a prohibited device, you will be dismissed from the test, and your scores will be voided. It is a serious violation. [4]

3. Can I use a calculator on all ACT sections?

No. Calculators are only permitted for the Mathematics Test. Use during any other section (English, Reading, Science) is prohibited. [4]

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

Yes, all versions of the TI-84 Plus (including Plus, CE) are explicitly allowed and are very popular choices for the test. [7] They are a safe bet for students looking for approved calculators you can use on the ACT in Nevada.

5. Is the TI-Nspire allowed?

This is a common point of confusion. The standard TI-Nspire (non-CAS) model is permitted. The TI-Nspire CAS model is prohibited. You must check your device carefully for the “CAS” designation. [5]

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

Yes, it is highly recommended. You must remove any programs or documents that have CAS functionality or store notes. Clearing the memory is the safest way to ensure you comply. [7] Learn more about effective study habits with our ACT study schedule guide.

7. What is the best calculator for the ACT?

The “best” calculator is one you are familiar and comfortable with. The TI-84 Plus is an excellent and popular choice because it’s powerful enough for all necessary calculations without being on the prohibited list. There’s no need to buy a brand new, complex calculator just for the test. Knowing how to use your permitted calculator efficiently is a key part of any ACT math strategy.

8. Can I share my calculator with another student?

No. Sharing of calculators during the test is strictly forbidden and can lead to disqualification for both students. [3]
