What are Calculators Permitted on SAT?
The term “calculators permitted on sat” refers to the specific set of rules and approved device lists published by the College Board for use during the mathematics section of the SAT exam. This policy is designed to ensure fairness and prevent any student from having an unfair advantage due to superior calculator technology. While students can use the built-in Desmos graphing calculator in the Bluebook testing app, many prefer to bring their own familiar device. Understanding which calculators are permitted is a critical part of test preparation. Generally, most scientific and graphing calculators are allowed, provided they don’t have prohibited features.
Common misconceptions often arise regarding the policy for calculators permitted on sat. Some students believe any graphing calculator is acceptable, but models with Computer Algebra Systems (CAS) are strictly forbidden. Another mistake is thinking a four-function calculator is sufficient; while allowed, it’s highly disadvantaged for the complexity of SAT math.
The Logic Behind the SAT Calculator Policy
There isn’t a single mathematical formula for determining if a calculator is allowed. Instead, the College Board uses a rule-based system that checks for specific prohibited features. The core principle is to allow tools for calculation but to forbid devices that can perform symbolic algebraic manipulation or communicate wirelessly. Knowing the list of calculators permitted on sat is essential for every test-taker.
The evaluation can be broken down into a decision-making process based on the calculator’s capabilities. Below is a table that explains the “variables” in this evaluation.
| Feature (Variable) | Meaning | Status on SAT | Example |
|---|---|---|---|
| Computer Algebra System (CAS) | Ability to manipulate algebraic expressions symbolically (e.g., factor, solve for x). | Prohibited | TI-Nspire CAS, HP Prime |
| QWERTY Keyboard | A full, typewriter-style keyboard. | Prohibited | TI-92 Plus |
| Wireless/Internet | Any feature for communication (Bluetooth, Wi-Fi, infrared). | Prohibited | Smartphones, Smartwatches |
| Stylus or Pen-Input | Touchscreen devices that use a stylus. | Prohibited | Casio ClassPad series |
| External Power | Requires a power cord to operate. | Prohibited | N/A (must be battery-operated) |
| Graphing Capability | Can plot equations on a coordinate plane. | Permitted (if non-CAS) | TI-84 Plus CE |
Practical Examples (Real-World Use Cases)
Example 1: The Standard Graphing Calculator
A student wants to know if their TI-84 Plus CE is on the list of calculators permitted on sat. They enter the model into the checker.
- Input: TI-84 Plus CE
- Analysis: The model does not contain “CAS”, “QWERTY”, or any other prohibited keyword. It is a widely recognized and accepted model.
- Output: PERMITTED. This is a standard and recommended graphing calculator for the SAT.
Example 2: The Prohibited CAS Calculator
Another student has a TI-Nspire CX II CAS. This is a powerful calculator, but they need to verify if it’s an approved device.
- Input: TI-Nspire CX II CAS
- Analysis: The model name explicitly contains “CAS”, which stands for Computer Algebra System. This feature is strictly prohibited.
- Output: NOT PERMITTED. The ‘CAS’ designation makes this calculator ineligible for the SAT.
How to Use This SAT Calculator Checker
Using this tool is straightforward and provides instant clarity on the status of your device. Following these steps ensures you are prepared on test day.
- Enter Your Calculator Model: Type the full model name of your calculator (e.g., “Casio fx-9750GII”) into the input field.
- Review the Instant Result: The primary result box will immediately update to show “PERMITTED”, “NOT PERMITTED”, or “CHECK FEATURES”.
- Analyze the Details: Check the intermediate results to see which, if any, prohibited features were detected and read the final recommendation.
- Check the Chart: The bar chart provides a visual representation of the calculator’s compliance status.
This tool helps you avoid the stress of being told on test day that your device is not one of the calculators permitted on sat. For more information, check out our guide to SAT prep.
Key Factors That Affect SAT Calculator Approval
Several critical factors determine whether a calculator is allowed. Understanding these rules is more important than memorizing a specific list, as new models are released regularly. The policy for calculators permitted on sat is very strict.
- Computer Algebra System (CAS): This is the most common reason for a graphing calculator to be banned. CAS can solve equations symbolically, which the College Board views as an unfair advantage.
- QWERTY Keyboards: Any calculator with a typewriter-style keyboard is prohibited as it facilitates text entry and storage.
- Communication Technology: Devices with Wi-Fi, Bluetooth, or any other wireless capability are strictly forbidden. This rule disqualifies phones, tablets, and smartwatches.
- Stylus/Pen Input: Calculators that use a stylus for input are not allowed, as they are considered computer-like devices.
- Power Requirements: Calculators must be battery-powered. Devices that need an electrical outlet are not permitted in the testing room.
- Noise and Printing: Any calculator that makes noise or has a paper tape printer is prohibited to avoid disturbing other test-takers.

Frequently Asked Questions (FAQ)
Yes, all versions of the TI-84 Plus (including Plus, Silver Edition, C Silver Edition, and CE) are among the most common and recommended calculators permitted on sat.
It depends. The standard TI-Nspire CX and CX II models are permitted. However, any model with “CAS” in its name (e.g., TI-Nspire CX II CAS) is strictly prohibited.
No, a calculator is not required. You can use the one built into the testing software (Bluebook) or no calculator at all. However, using a familiar, approved calculator is highly recommended for efficiency. More tips can be found on our SAT tips page.
The proctor will not allow you to use it. You will have to take the math section without a calculator or use the built-in one, potentially putting you at a disadvantage.
Yes, all scientific calculators are permitted. They are a good option if you are comfortable with their functions and do not need graphing capabilities. For a list of models, see our approved calculator list.
No. Phones, smartwatches, tablets, and laptops are never allowed to be used as calculators during the exam.
The College Board recommends but does not always require it. Some test centers may ask you to clear the memory on your device before the test begins. It’s a good practice to do so.
Yes, a major recent change is that calculators with CAS functionality are no longer permitted on the SAT, aligning the policy more closely with the ACT. It’s crucial to check the latest rules for calculators permitted on sat.
