SAT Approved Calculators Checker

Instantly verify if your calculator is permitted on the SAT exam based on the latest College Board policy.

Check Your Calculator’s Status

Policy Basis: The result is based on the official College Board list of prohibited features. Key restrictions include devices with QWERTY keyboards, Computer Algebra Systems (CAS), wireless communication, or those that require a power outlet.

What Are SAT Approved Calculators?

SAT approved calculators are specific handheld electronic devices that the College Board permits students to use on the Math section of the SAT exam. The policy is designed to ensure fairness and prevent any student from having an unfair advantage. While a calculator is not required to solve any question, using a familiar and permitted device can help you work more efficiently. The list of SAT approved calculators includes most graphing calculators, scientific calculators, and four-function calculators, but certain features are strictly prohibited.

Anyone preparing for the SAT should familiarize themselves with the official calculator policy. Misunderstanding the rules could lead to your calculator being confiscated on test day. Common misconceptions include believing all graphing calculators are allowed, or that the newest, most advanced model is always the best choice. In fact, some advanced models with features like a Computer Algebra System (CAS) are explicitly banned.

SAT Calculator Policy and Rules Explained

The “formula” for determining if a calculator is approved isn’t a single mathematical equation, but a set of rules and restrictions defined by the College Board. The core principle is to allow tools for calculation without providing access to features that could solve problems symbolically or give access to outside information. Understanding these rules is essential for selecting from the list of SAT approved calculators.

Feature Restrictions for SAT Approved Calculators

Feature / Rule	Status	Reasoning	Typical Range of Compliance
Computer Algebra System (CAS)	Prohibited	Can perform symbolic algebra (e.g., factor, solve for variables), which is considered an unfair advantage.	Models with “CAS” in their name are banned (e.g., TI-Nspire CX II CAS).
QWERTY-style Keyboard	Prohibited	These keyboards are for text input and resemble a computer, which is not allowed.	Any device with a typewriter-like keyboard layout is banned.
Wireless/Internet Access	Prohibited	Prevents any form of communication or access to external information during the exam.	No Wi-Fi, Bluetooth, or cellular capabilities.
Requires Electrical Outlet	Prohibited	Calculators must be battery-powered to ensure they can be used at any testing center.	Must operate on batteries (check them before the test!).
Makes Noise or Prints	Prohibited	To avoid distracting other test-takers. Calculators with paper tape are banned.	Any calculator that makes sounds or has a printing function is not allowed.

Practical Examples of SAT Approved Calculators

Example 1: The Popular Choice

A student has a Texas Instruments TI-84 Plus CE. They enter the brand and model into the calculator. The result is APPROVED. The TI-84 series is one of the most common and recommended models for the SAT. It provides powerful graphing capabilities without having a prohibited CAS. This is a perfect example of a compliant and effective tool for the exam.

Example 2: A Prohibited Model

Another student has an HP Prime graphing calculator. When they check this model, the result is PROHIBITED. The HP Prime includes a powerful Computer Algebra System (CAS), which is explicitly banned by the College Board. While an excellent calculator for advanced math classes, it is not one of the SAT approved calculators and cannot be used on the test.

How to Use This SAT Approved Calculators Calculator

Using this tool is straightforward. Follow these steps to determine if your device is one of the SAT approved calculators:

1. Select the Brand: Choose your calculator’s brand from the dropdown menu (e.g., Texas Instruments, Casio, HP).
2. Enter the Model: Type the model number into the text field. Be as precise as possible.
3. Review the Result: The tool will instantly provide a status: APPROVED, PROHIBITED, or UNKNOWN.
4. Check the Details: The feature checklist gives you an idea of why a certain model might be prohibited, focusing on key restrictions like CAS and QWERTY keyboards.

Use the result to make an informed decision. If your calculator is prohibited, you will need to acquire an approved model for test day. For more test prep advice, see our guide on PSAT requirements.

Key Factors That Affect SAT Calculator Approval

Several key features determine whether a device is included in the list of SAT approved calculators. Understanding these will help you choose the right tool.

• Computer Algebra System (CAS): This is the most significant factor. CAS functionality allows a calculator to manipulate algebraic expressions symbolically. The College Board has banned all CAS calculators to ensure a level playing field.
• QWERTY Keyboard: Calculators with a full (QWERTY) keyboard are prohibited as they are considered computing devices.
• Internet and Communication: Any device with the ability to communicate wirelessly (Wi-Fi, Bluetooth) is strictly forbidden.
• Power Source: The device must be battery-operated. Calculators that need to be plugged into an electrical outlet are not allowed.
• Physical Size and Display: Calculators with very large or raised displays might lead to special seating arrangements to prevent others from seeing your screen.
• Prohibited Peripherals: Styluses for touch screens are generally not permitted. Likewise, devices that make noise or print to paper tape are banned.

Frequently Asked Questions (FAQ)

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

Yes, the TI-84 Plus, including the CE version, is one of the most popular and universally SAT approved calculators. It has all the necessary graphing functions without a prohibited CAS.

2. What happens if I bring a banned calculator to the test?

If a proctor identifies your calculator as a prohibited model, you will not be allowed to use it. They will not provide a replacement, so you would have to take the math section without a calculator.

3. Can I use the calculator on all sections of the SAT?

No, calculator use is only permitted on the Math with Calculator section. You cannot use it on the Reading and Writing section or the Math No-Calculator section.

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

The College Board requires you to remove any stored programs or documents that have algebra functionality, like equation solvers. It’s best practice to clear your RAM before the test.

5. Are scientific calculators allowed?

Yes, all standard scientific calculators are allowed. They are a good option if you don’t need graphing capabilities. Our guide to scientific calculators can help you choose.

6. What is the difference between a CAS and a non-CAS calculator?

A non-CAS calculator gives numerical answers (e.g., 2.5). A CAS-enabled calculator can give symbolic answers (e.g., 5/2 or x+y). This symbolic manipulation is what makes CAS calculators prohibited on the SAT.

7. Should I buy a new calculator for the SAT?

Not necessarily. The best calculator is one you are familiar with. If your current school calculator is on the list of SAT approved calculators, it’s better to use that than to learn a new one right before the exam.

8. Is the built-in Desmos calculator on the digital SAT good enough?

Yes, the embedded Desmos calculator is very powerful and is sufficient for all questions. If you are comfortable using it with a mouse/trackpad, you may not need to bring a handheld calculator at all. Check our digital SAT tips for more info.
