SAT Calculator Policy Guide
SAT Calculator Eligibility Checker
Answer the questions below to determine if your calculator is likely allowed for the SAT exam based on the official policy.
This is a major prohibited feature.
Stylus-operated devices are not permitted.
No wireless communication of any kind is allowed.
Only battery-operated calculators are allowed.
Calculators must be silent and cannot print.
These devices are strictly forbidden.
CAS calculators are prohibited for SAT tests. This feature can symbolically solve equations.
Understanding the SAT Calculator Policy
Navigating the rules for what calculators are allowed for the SAT can be confusing. The College Board sets specific guidelines to ensure fairness and prevent any academic dishonesty during the exam. This article breaks down the policy, provides examples, and helps you confirm your device is test-day ready.
What is the SAT Calculator Policy?
The SAT calculator policy defines which calculators are permitted and which are prohibited during the math portion of the test. You can’t use a calculator on the Reading and Writing section. While most graphing, scientific, and four-function calculators are allowed, specific features will disqualify a device. The goal is to allow a tool for computation without giving some students an unfair advantage through advanced functionalities. Bringing your own approved, battery-operated calculator is your responsibility, as test centers do not provide them.
The “Formula” for an Allowed Calculator
The decision isn’t based on a mathematical formula but a logical one. A calculator is generally allowed if it does NOT have any of the features listed in our checker. The core rule is: If a feature allows for communication, symbolic manipulation, or resembles a computer, it’s likely banned.
| Feature/Variable | Meaning | SAT Status | Typical Range (for this tool) |
|---|---|---|---|
| QWERTY Keyboard | A computer-style keyboard. | Prohibited | Yes/No |
| Wireless Capability | Internet, Bluetooth, Infrared. | Prohibited | Yes/No |
| External Power | Requires an electrical outlet. | Prohibited | Yes/No |
| Computer Algebra System (CAS) | Solves algebra symbolically, factors expressions. | Prohibited | Yes/No |
| Stylus/Pen Input | Using a stylus or pen for input. | Prohibited | Yes/No |
| Phone/Laptop/Tablet | Is it a multi-purpose computing device? | Prohibited | Yes/No |
Practical Examples
Example 1: A Texas Instruments TI-84 Plus
This is one of the most common and recommended calculators.
- Inputs: Does it have a QWERTY keyboard? (No), Wireless? (No), CAS? (No, the standard model doesn’t), Is it a phone? (No).
- Result: Likely Allowed. The TI-84 Plus family is a standard and fully approved for the exam.
Example 2: A Phone’s Calculator App
- Inputs: Is it a phone? (Yes), Does it have wireless capability? (Yes).
- Result: Not Allowed. Smartphones, tablets, and laptops are explicitly banned for use as calculators during the SAT.
Example 3: An HP Prime with CAS
- Inputs: Does it have a Computer Algebra System (CAS)? (Yes).
- Result: Not Allowed. The College Board has prohibited calculators with CAS functionality.
How to Use This SAT Calculator Eligibility Checker
This tool simplifies the official policy. Follow these steps:
- Examine your calculator for the features listed.
- For each question, check the box if your calculator has that feature.
- The result will update in real-time. A “Not Allowed” result will specify exactly which prohibited feature was selected.
- If all boxes remain unchecked, your calculator is likely compliant with the SAT calculator policy.
- Use the ‘Reset’ button to clear your selections and start over.

Key Factors That Affect Calculator Approval
Understanding these factors is crucial for knowing what calculators are allowed for the sat.
- Computer Algebra System (CAS): This is a major change. Calculators that can solve algebraic equations symbolically (like the TI-89 or TI-Nspire CAS) are prohibited.
- QWERTY Keyboard: Any device with a typewriter-like keyboard is banned.
- Communication: Any form of wireless or wired communication (Bluetooth, Wi-Fi, Infrared) is strictly forbidden.
- Power Source: Only battery-powered devices are allowed. No power cords.
- Peripherals: Calculators that use a stylus, print, or make noise are not allowed.
- Device Type: It must be a dedicated calculator, not a feature on a phone, tablet, or laptop.

Frequently Asked Questions (FAQ)
1. Is the TI-84 Plus allowed on the SAT?
Yes, the Texas Instruments TI-84 Plus series (including Plus, Plus CE, etc.) is one of the most popular and widely accepted graphing calculators for the SAT.
2. Are Computer Algebra System (CAS) calculators allowed?
No. As of recent policy updates, calculators with CAS functionality are explicitly prohibited on the SAT. You must ensure your calculator is a non-CAS model.
3. What if my calculator has games on it?
While the College Board doesn’t have a specific rule against games, they do require you to clear any stored programs that can perform algebraic manipulations. It is best practice to clear the memory before the test.
4. Do I have to clear my calculator’s memory?
Yes, you must remove any programs or documents, especially those with algebra functionality. Proctors may inspect your calculator.
5. Can I use the calculator on the entire SAT Math section?
Yes, the calculator is permitted for the entire Math section on the digital SAT. However, you cannot use it on the Reading and Writing section.
6. What happens if I bring a prohibited calculator?
You will not be allowed to use it. If you are caught using a prohibited device during the test, you will be dismissed, and your scores will be canceled.
7. Where can I find the official, most up-to-date list?
The College Board’s official website is the definitive source for the sat calculator policy. They no longer maintain a list of approved models, but rather a list of prohibited features and specific banned models.
8. Can I share my calculator with another student?
No. Sharing calculators is strictly forbidden during the exam. Each student must have their own device.
