What is the SAT Calculator Policy?
The SAT Calculator Policy is a set of rules from the College Board that defines which calculators are acceptable for use on the SAT test. The policy ensures fairness by preventing students from gaining an unfair advantage through advanced computational tools. While the digital SAT, administered on the Bluebook™ application, includes a built-in Desmos-powered graphing calculator, students are still permitted to bring their own approved handheld devices. Knowing whether your device is one of the acceptable calculators for the sat is critical to avoid issues on test day.
SAT Calculator Rules Explained
There isn’t a single formula for what’s allowed, but a series of guidelines. The core principle is that calculators are tools for computation, not for storing information or providing symbolic algebraic manipulation. The College Board prohibits any device that can communicate wirelessly, has a QWERTY keyboard, or requires an external power source. A key recent change is the prohibition of calculators with a Computer Algebra System (CAS).
| Rule Category | Explanation | Status |
|---|---|---|
| General Type | All scientific, most graphing, and all four-function calculators are allowed. | Permitted |
| Computer Algebra System (CAS) | Calculators that can perform symbolic algebra (e.g., factor x²+2x+1) are banned. Models with “CAS” in their name are prohibited. | Prohibited |
| Keyboard | Devices with a typewriter-style (QWERTY) keyboard are not allowed. | Prohibited |
| Connectivity | Calculators with wireless, Bluetooth, or internet capabilities are banned. | Prohibited |
| Power Source | Only battery-operated calculators are permitted. No devices that need to be plugged into an electrical outlet. | Permitted |
| Other Devices | Laptops, tablets, smartwatches, and cell phones are strictly forbidden. | Prohibited |
Practical Examples
Example 1: A Permitted Calculator
- Input Model: TI-84 Plus
- Analysis: The TI-84 Plus is a standard graphing calculator. It does not have a QWERTY keyboard, internet access, or a CAS. It is widely listed as an approved model.
- Result: Acceptable for use on the SAT.
Example 2: A Prohibited Calculator
- Input Model: TI-89 Titanium
- Analysis: The TI-89 series includes a built-in Computer Algebra System (CAS), which is explicitly banned by the College Board.
- Result: Not Acceptable for use on the SAT.
How to Use This SAT Calculator Checker
Using our tool is simple and designed to give you a quick, clear answer about acceptable calculators for the sat.
- Enter the Model: Type the full model name of your calculator (e.g., “Casio fx-991EX”) into the input field above. The model is usually printed on the front of the device.
- Click “Check”: Press the “Check My Calculator” button to run the verification.
- Review the Result: The tool will instantly tell you if your calculator is likely ‘Acceptable’, ‘Not Acceptable’, or if the model isn’t in our database. It will also provide a brief explanation for the result. For more help with your test, check out our test day checklist.
Key Factors That Affect SAT Calculator Acceptance
- CAS (Computer Algebra System): This is the most significant factor. If your calculator can solve algebraic equations symbolically, it’s banned.
- QWERTY Keyboard: Any calculator with a computer-style keyboard is prohibited.
- Wireless Capability: Any form of internet, Bluetooth, or infrared communication is forbidden.
- Stylus/Pen Input: Models requiring a stylus, like the Casio ClassPad, are not allowed.
- Power Source: The calculator must be battery-powered. Ensure you have fresh batteries for test day!
- Physical Size & Noise: Devices that are oversized, make noise, or have a paper tape printer are generally not allowed.

Frequently Asked Questions (FAQ)
1. Can I use a TI-84 Plus on the SAT?
Yes, all versions of the TI-84 Plus (including Plus, C Silver Edition, and CE) are acceptable calculators for the SAT as they do not have a CAS.
2. Is the TI-Nspire allowed on the SAT?
It depends on the model. The standard TI-Nspire CX and CX II are allowed. However, the TI-Nspire CX CAS and CX II CAS versions are explicitly prohibited.
3. What happens if I bring a banned calculator?
Test center staff will not allow you to use a prohibited calculator. You may have to take the math section without a calculator, which is a significant disadvantage.
4. Do I need a graphing calculator for the SAT?
While not strictly required, a graphing calculator is highly recommended. It can save time on questions involving functions and graphs. All scientific calculators are also permitted. For a detailed comparison, see our graphing calculator guide.
5. Are all scientific calculators allowed?
Yes, all scientific calculators are allowed, provided they don’t have any prohibited features like a QWERTY keyboard or wireless capabilities.
6. What is a Computer Algebra System (CAS)?
A CAS is a sophisticated program that can manipulate mathematical expressions in a symbolic way, much like a human would. For example, it can factor polynomials, solve for variables in terms of other variables, and find symbolic derivatives. This capability is considered an unfair advantage and is why CAS calculators are banned.
7. Does the digital SAT have a built-in calculator?
Yes, the digital SAT provided through the Bluebook app includes an embedded Desmos graphing calculator that you can use for the entire math section. However, you are still allowed to bring your own approved handheld calculator.
8. Where can I find the official list of acceptable calculators for the SAT?
The College Board no longer publishes a comprehensive list of *approved* models. Instead, they maintain a list of explicitly *prohibited* calculators and features. Our tool uses these rules to help you check your model. You can also explore our digital sat guide for more information.
