What is the SAT Calculator Policy?

The SAT Calculator Policy is a set of rules established by the College Board to ensure fairness and test integrity for all students taking the SAT. This policy specifies which calculators are permitted for use on the Math with Calculator section and which are forbidden. The goal is to prevent any student from having an unfair technological advantage. While all math problems on the SAT can be solved without a calculator, using an approved one can significantly improve speed and accuracy. Students must bring their own approved, battery-powered calculator; they are not provided at the test center.

A common misconception is that all graphing calculators are allowed. This is not true. While most are, models with specific features like a Computer Algebra System (CAS) or a QWERTY keyboard are strictly prohibited. Understanding the nuances of the SAT Calculator Policy is crucial for test day success. You can check the Digital SAT Guide for official rules.

The Logic Behind the SAT Calculator Policy

Instead of a mathematical formula, the SAT Calculator Policy operates on a set of logical rules based on calculator features. The College Board’s primary aim is to permit tools that assist with calculation, not those that solve problems conceptually or provide access to external information. The “formula” for acceptance can be understood by evaluating a calculator’s features against the prohibited list.

Key variables evaluated under the SAT Calculator Policy.

Variable (Feature)	Meaning	Permitted Value	Typical Range
has_cas	Computer Algebra System	False	True / False
has_qwerty	QWERTY-style keyboard	False	True / False
is_wireless	Internet/Bluetooth capability	False	True / False
uses_stylus	Requires a stylus for operation	False	True / False
is_part_of_device	Is a phone, laptop, or tablet	False	True / False

Practical Examples

Example 1: A Permitted Calculator

A student has a Texas Instruments TI-84 Plus CE. They use the checker tool above.

Input: “TI-84 Plus CE”

Output: ALLOWED.

Interpretation: This calculator is one of the most common and recommended models. It has graphing capabilities but does not have a prohibited CAS or QWERTY keyboard. It is fully compliant with the SAT Calculator Policy. For more details, see our ACT vs SAT comparison.

Example 2: A Prohibited Calculator

A student has a Texas Instruments TI-Nspire CX II CAS.

Input: “TI-Nspire CX II CAS”

Output: NOT ALLOWED.

Interpretation: The “CAS” (Computer Algebra System) in the model name immediately disqualifies it. CAS calculators can solve algebraic equations symbolically, which provides an unfair advantage according to the College Board’s rules. The student must acquire a non-CAS model for the test.

How to Use This SAT Calculator Policy Checker

Using this tool is straightforward and designed to give you a clear answer in seconds. Follow these steps:

1. Enter Calculator Model: Type the model name of your calculator into the input field. Be as specific as possible (e.g., “TI-84 Plus” instead of just “TI”).
2. Check Status: Click the “Check Status” button.
3. Review the Result: The tool will display one of three outcomes:
   • ALLOWED: Your calculator is on the approved list.
   • NOT ALLOWED: Your calculator is on the prohibited list. The reason will be provided.
   • CHECK MANUALLY: The model was not found in our database. This means you should carefully check its features against the prohibited list below or consult the official SAT guide.
4. Reset: Click the “Reset” button to clear the inputs and results for a new search.

Key Factors That Affect SAT Calculator Approval

Several key features determine whether a calculator is compliant with the SAT Calculator Policy. Understanding these will help you choose the right tool for test day.

• Computer Algebra System (CAS): This is the most critical factor. CAS-enabled calculators (like the TI-Nspire CAS or HP Prime) can manipulate variables and solve equations symbolically. They are strictly forbidden as of 2025.
• QWERTY Keyboard: Any calculator with a keyboard laid out like a computer’s is not allowed. This prevents students from storing notes.
• Connectivity: Devices with Wi-Fi, Bluetooth, or any cellular connection are banned to prevent communication. This includes smartphones and smartwatches.
• Power Source: Calculators requiring an electrical outlet are not permitted. Your device must be battery-operated.
• Stylus/Pen Input: Devices that use a stylus, like the Casio ClassPad series, are prohibited.
• Noise and Printing: Calculators that make noise or print to paper tape are not allowed as they can distract other test-takers.

Frequently Asked Questions (FAQ)

1. Can you use a graphing calculator on the SAT?
Yes, most graphing calculators are allowed, provided they do not have prohibited features like a Computer Algebra System (CAS). Models like the TI-84 Plus series are very popular and fully approved.

2. Is the TI-Nspire allowed on the SAT?
It depends. The non-CAS versions (like the TI-Nspire CX and CX II) are allowed. However, the models with “CAS” in their name (TI-Nspire CX CAS, TI-Nspire CX II CAS) are strictly prohibited.

3. What happens if I bring a prohibited calculator?
If a proctor identifies your calculator as prohibited, you will not be allowed to use it. In the worst-case scenario, you could be dismissed from the test and have your score canceled.

4. Do I have to clear my calculator’s memory?
The College Board requires you to remove any stored documents and programs that have algebra functionality (e.g., equation solvers). It’s best practice to clear the memory before test day.

5. Are scientific calculators allowed on the SAT?
Yes, all scientific calculators are permitted for use on the SAT Math with Calculator section.

6. Can I use the Desmos calculator on the digital SAT?
Yes, the digital SAT, administered via the Bluebook app, has a built-in Desmos graphing calculator that all students can use. You are still allowed to bring your own approved handheld calculator as well.

7. What’s the difference between a CAS and a non-CAS calculator?
A non-CAS calculator gives numerical answers (e.g., 2.5). A CAS calculator can give symbolic answers (e.g., 5/2 or x = 2y). This symbolic manipulation capability is what makes CAS calculators prohibited on the SAT.

8. Is the TI-89 allowed on the SAT?
No. The TI-89 and TI-89 Titanium both have CAS functionality and are explicitly on the prohibited list for the SAT Calculator Policy.
