Key Intermediate Values
This checker uses the official College Board guidelines for calculators allowed in SAT. The key factors determining a calculator’s status are:
- Computer Algebra System (CAS): Is the calculator a CAS model? CAS functionality is BANNED.
- QWERTY Keyboard: Does it have a computer-style keyboard? This is BANNED.
- Wireless/Internet: Does it have Wi-Fi, Bluetooth, or cellular capabilities? This is BANNED.
- Official Approved List: Is the model explicitly listed as approved by the College Board?
Calculator Approval by Manufacturer
What is the SAT Calculator Policy?
The calculators allowed in SAT are governed by a strict policy set by the College Board to ensure fairness and prevent any student from having an unfair advantage. For the digital SAT, a calculator is permitted on the entire Math section. While the testing application (Bluebook) has a built-in Desmos graphing calculator, students are allowed and encouraged to bring their own familiar, approved device.
This policy is for everyone taking the SAT. Understanding the rules for calculators allowed in SAT is crucial to avoid issues on test day. A common misconception is that all graphing calculators are fine, but certain advanced models, especially those with a Computer Algebra System (CAS), are explicitly prohibited.
Official Rules and Guidelines
There isn’t a single mathematical formula for determining if a calculator is allowed. Instead, the College Board provides a list of rules and prohibited features. The most significant rule is the ban on calculators with Computer Algebra System (CAS) functionality. These systems can solve algebraic equations symbolically, which is considered an unfair advantage. Here’s a breakdown of the key rules governing calculators allowed in SAT.
Prohibited Feature Reference Table
| Feature/Rule | Meaning | Example of Prohibited Model | Typical Range |
|---|---|---|---|
| Computer Algebra System (CAS) | Manipulates symbolic expressions (e.g., factors x²+2x+1). | TI-Nspire CX II CAS, HP Prime | Any model with “CAS” in its name. |
| QWERTY Keyboard | Has a computer-style keyboard for typing text. | Devices with slide-out keyboards. | Any text-entry device. |
| Wireless/Internet | Connects via Wi-Fi, Bluetooth, or cellular data. | Smartphones, tablets, smartwatches. | Any device with communication ability. |
| External Power | Needs to be plugged into an electrical outlet. | Laptops, some older printing calculators. | Must be battery-operated only. |
| Stylus/Pen Input | Uses a stylus for input on a touchscreen. | Casio ClassPad series. | Some specific models like FX-CG500 are allowed but the stylus use is forbidden. |

Practical Examples
Example 1: A Clearly Allowed Calculator
A student has a TI-84 Plus CE. They enter “TI-84 Plus CE” into the checker.
- Input: TI-84 Plus CE
- Analysis: This model does not have CAS, a QWERTY keyboard, or wireless capabilities. It is one of the most common calculators allowed in SAT and appears on all official approval lists.
- Output: The calculator status is ALLOWED.
Example 2: A Clearly Prohibited Calculator
A student has a TI-89 Titanium. They enter “TI-89 Titanium” into the checker.
- Input: TI-89 Titanium
- Analysis: The TI-89 series is explicitly banned by the College Board because it includes a powerful Computer Algebra System (CAS).
- Output: The calculator status is NOT ALLOWED.
Compare this with the ACT calculator policy which has similar but distinct rules.
How to Use This SAT Calculator Checker
This tool helps you quickly determine if your device is on the list of calculators allowed in SAT. Follow these simple steps:
- Find Your Model Number: Look at the top of your calculator to find the exact model name (e.g., Casio fx-9750GII).
- Enter the Model: Type the full model name into the input field above.
- Review the Result: The tool will instantly provide one of three results:
- ALLOWED: Your calculator is approved for use on the SAT.
- NOT ALLOWED: Your calculator has a prohibited feature (like CAS) and cannot be used.
- UNCERTAIN: The model was not found in our lists. You MUST check the official College Board website to confirm its status.
- Reset: Click the “Reset” button to clear the fields and start over.
Key Factors That Affect Calculator Approval
Several factors determine the status of calculators allowed in SAT. Understanding them helps you choose the right tool.
- Computer Algebra System (CAS): This is the most critical factor. CAS can perform symbolic algebra, giving a significant advantage. Calculators with CAS are banned.
- QWERTY Keyboards: Any device with a typewriter-style keyboard is prohibited to prevent text storage and communication.
- Connectivity: Calculators with any form of wireless or internet connection (Bluetooth, Wi-Fi, etc.) are strictly forbidden.
- Power Source: The calculator must be battery-powered. Devices that require an electrical outlet are not allowed.
- Stylus and Touchscreens: Most devices requiring a stylus are banned. While some touchscreen calculators are allowed, the stylus functionality is prohibited.
- Noise and Printing: Calculators that make noise or print to paper tape are not permitted in the testing room.
Practicing with an approved calculator is a key part of effective Digital SAT prep.
Frequently Asked Questions (FAQ)
What is the best calculator for the SAT?
The “best” calculator is one you are comfortable with. However, the TI-84 Plus series is widely recommended due to its balance of functionality and user-friendliness. The TI-Nspire CX (non-CAS) is also a powerful and popular choice.
Can I use my phone as a calculator?
No. Smartphones, smartwatches, laptops, and tablets are strictly prohibited from being used as calculators.
What happens if I bring a banned calculator?
If a proctor discovers you have a prohibited device, you may be dismissed from the test, and your scores will be canceled. It is your responsibility to ensure your device is on the list of calculators allowed in SAT.
Do I need to clear my calculator’s memory?
Yes, test proctors may require you to clear your calculator’s memory before the test begins to ensure no unfair information is stored.
Are all scientific calculators allowed on the SAT?
Yes, generally all scientific calculators are permitted as they do not have the advanced prohibited features like CAS or graphing.
What if my calculator is not on the approved list?
If your calculator model doesn’t appear on any official list, it’s safest to assume it might not be allowed. You should acquire an explicitly approved model for test day to avoid any risk. Check our guide on choosing a graphing calculator for tips.
Is there a “no calculator” section on the digital SAT?
No, for the digital SAT, a calculator is allowed on the entire Math section. The paper-based SAT previously had a “no calculator” portion.
Can I share my calculator with another student?
No, sharing calculators is strictly forbidden during the exam. Each student must have their own approved calculator.
