SAT Calculator & Program Policy Checker

An easy-to-use tool to determine: can I use calculator programs on the SAT?

Is Your Calculator Allowed?

Check the features of your handheld calculator below. This tool will tell you if it’s permitted based on the official SAT calculator policy.

Your result will be displayed here.

What is the SAT Calculator Policy?

The SAT calculator policy outlines which calculators are permitted for use on the math section of the exam. The goal is to ensure fairness and prevent any student from having an unfair advantage. While you can use the built-in Desmos graphing calculator provided in the testing software, you are also allowed to bring your own handheld calculator. This policy covers everything from the physical features of the calculator (like keyboards and power sources) to its software capabilities, such as whether it has a Computer Algebra System (CAS). The question, “can I use calculator programs on the SAT?“, is a common one, and the answer depends on whether the calculator itself is allowed and what the programs do.

The SAT Calculator “Formula”: Rules for Acceptance

Think of the SAT calculator policy as a formula with several variables. If any prohibited variable is “true,” the calculator is not allowed. The core rule is that the device’s primary purpose must be as a calculator, and it cannot have features that could compromise test security.

SAT Calculator Feature Rules

Feature/Variable	Meaning	Status	Typical Range (Example)
QWERTY Keyboard	A typewriter-style keyboard.	Prohibited	Any device with this feature.
Wireless Connectivity	Internet, Bluetooth, cellular, infrared ports.	Prohibited	Smartphones, smartwatches, advanced calculators.
External Power	Requires an electrical outlet to function.	Prohibited	Laptops, non-handheld devices.
CAS (Computer Algebra System)	Manipulates symbolic algebraic equations.	Prohibited (Effective Aug 2025)	TI-89, TI-Nspire CAS.
Calculator Programs	User-added programs to perform calculations.	Allowed*	Quadratic formula solvers, unit converters.

*Allowed, provided the programs do not add prohibited functionality (like CAS features) and the calculator itself is on the approved list.

Practical Examples

Example 1: The Standard Graphing Calculator

• Device: TI-84 Plus CE.
• Inputs: No QWERTY, no wireless, no CAS. Has programs for solving quadratic equations.
• Result: Allowed. The TI-84 Plus is a standard approved calculator. Simple programs that save steps or perform calculations are permitted. Many students ask if they can use calculator programs on the SAT, and for this type of device, the answer is yes.

Example 2: The Prohibited CAS Calculator

• Device: TI-89 Titanium.
• Inputs: Has a powerful built-in Computer Algebra System (CAS) that solves equations symbolically.
• Result: Prohibited. Even though it has no QWERTY keyboard, its CAS functionality gives an unfair advantage and is banned.

How to Use This SAT Calculator Policy Checker

1. Review Your Calculator: Look at your physical calculator and identify its features.
2. Check the Boxes: In the tool above, check the box for each feature your calculator has. If you’ve loaded programs onto it, be sure to check the “Have you added programs?” box.
3. Click “Check Permissibility”: The tool will instantly apply the SAT calculator policy rules.
4. Interpret the Result: The output will tell you if the calculator is “Allowed” or “Prohibited” and provide the specific reason based on your selections. This directly answers the question, “can I use calculator programs on the SAT” for your specific device.

Key Factors That Affect if a Calculator is Allowed

Understanding these factors is crucial for test day. The policy is designed to prevent cheating and ensure a level playing field.

• Communication Ability: Any feature that can be used to communicate with other devices is strictly forbidden. This includes Bluetooth, Wi-Fi, and infrared ports.
• Computer-like Features: A QWERTY keyboard is the most obvious prohibited feature, as it makes the device too much like a computer.
• Power Source: The calculator must be battery-powered. Devices needing an outlet are not allowed.
• Symbolic Manipulation (CAS): This is a major factor. A CAS can solve `x + 2y = 4` for `x`, while a normal calculator cannot. This feature is now banned.
• Physical Distractions: Calculators that make noise or print on a paper tape are banned to avoid distracting other test-takers.
• General Purpose Devices: You cannot use a smartphone, tablet, or laptop, even if you are only using its calculator function.

Frequently Asked Questions (FAQ) About SAT Calculator Programs

1. So, can I use calculator programs on the SAT definitively?

Yes, you can, as long as the calculator itself is an approved model and the programs don’t violate any rules. Programs designed to save time (e.g., solving the quadratic formula) or store scientific formulas are generally fine. You must remove any programs that add CAS functionality.

2. What if my calculator has games on it?

While the policy doesn’t explicitly mention games, proctors can confiscate any device they deem suspicious. It is highly recommended to remove all non-essential programs, including games, to avoid any issues on test day.

3. How do I know if my calculator has a CAS?

Calculators with a Computer Algebra System often have “CAS” in their model name (e.g., TI-Nspire CX II CAS). A key test is to see if it can solve an algebraic equation and give you a variable answer (like `x = 2y-4`) instead of just a number. If it can, it’s a CAS calculator and is prohibited.

4. Do I need to clear my calculator’s memory before the test?

The College Board requires you to remove any programs that have CAS-like functionality or stored documents. While you don’t need to wipe all programs, it’s a good practice to clean up your calculator and only keep essential, permitted programs.

5. Is the built-in Desmos calculator good enough?

Yes, for most students, the Desmos calculator provided in the Bluebook testing app is powerful enough for the entire math section. It’s a full-featured graphing calculator. If you plan to use it, practice with the online version beforehand.

6. What happens if I’m caught with a prohibited calculator?

If you are found using a prohibited calculator, you will be dismissed from the test, and your scores will be canceled. It is your responsibility to ensure your calculator is compliant.

7. Can I use a TI-84 Plus or TI-Nspire CX II on the SAT?

Yes, the TI-84 Plus family is fully approved. The non-CAS version of the TI-Nspire CX II is also approved. However, the TI-Nspire CX II CAS model is prohibited.

8. Does this policy apply to the digital SAT?

Yes, these rules apply to all administrations of the SAT, including the digital version. You can either use your own approved handheld calculator or the integrated Desmos calculator. Familiarize yourself with our Digital SAT Guide for more details.
