What is the SAT Calculator Policy?
The SAT calculator policy outlines the rules regarding which calculators you can use on the SAT. The College Board, the organization that administers the SAT, sets these rules to ensure fairness and test security. While you are allowed to use a calculator on the Math section, not all devices are permitted. The policy specifies which types (graphing, scientific, four-function) are acceptable and which features (like Wi-Fi, QWERTY keyboards, or a Computer Algebra System) are strictly prohibited. Understanding these rules is critical for every student preparing for the test.
This policy primarily applies to students who plan to bring their own device to the test center. For students taking the digital SAT, there is also an embedded Desmos graphing calculator available within the testing application, Bluebookâ˘. Knowing the policy on external calculators you can use on the SAT ensures you won’t face any issues on test day.
Understanding the SAT Calculator Policy: The Rules
The core of the policy is to allow tools that perform calculations without giving an unfair advantage. The rules are not based on brand or price, but on functionality. A key recent update is the prohibition of all calculators with Computer Algebra System (CAS) functionality. A CAS can manipulate algebraic expressions symbolically, which the College Board now considers a distinct advantage.
Here is a breakdown of the key features and rules that determine which calculators you can use on the SAT.
| Feature/Rule | Meaning | Why it’s Prohibited | Status |
|---|---|---|---|
| Computer Algebra System (CAS) | Can solve equations symbolically (e.g., factor x^2-4 into (x-2)(x+2)). | Provides an unfair advantage in solving algebra problems. | PROHIBITED |
| QWERTY Keyboard | A typewriter-style keyboard. | Resembles a computer, potential for storing notes. | PROHIBITED |
| Wireless/Internet Access | Features like Wi-Fi, Bluetooth, or cellular data. | Risk of external communication and cheating. | PROHIBITED |
| Stylus or Pen Input | Touchscreen devices that require a stylus. | Often part of PDA-like devices with prohibited features. | PROHIBITED |
| Power Cords | Calculators that must be plugged into an outlet. | Only battery-operated devices are allowed for portability and safety. | PROHIBITED |
| Sharing Calculators | Giving your calculator to another student. | Each student must have their own approved device. | PROHIBITED |
Practical Examples (Real-World Use Cases)
Let’s look at two common scenarios to understand how the policy on calculators you can use on the SAT works in practice.
Example 1: The Student with a TI-Nspire CX II-T CAS
- Calculator Model: TI-Nspire CX II-T CAS
- Analysis: This is a powerful graphing calculator. The key issue is the “CAS” in its name, which stands for Computer Algebra System. The College Board explicitly prohibits calculators with CAS functionality.
- Result: PROHIBITED. This student would need to get a different, non-CAS calculator for the exam, such as a model from the TI-84 on SAT series.
Example 2: The Student with a TI-84 Plus
- Calculator Model: TI-84 Plus
- Analysis: This is one of the most common graphing calculators used by high school students. It does not have a CAS, a QWERTY keyboard, or any wireless capabilities. It falls squarely within the approved guidelines.
- Result: ALLOWED. This is a perfect example of one of the many graphing calculators you can use on the SAT. The student can confidently bring this device to the test.
How to Use This SAT Calculator Eligibility Calculator
Our tool simplifies the process of checking your calculator. Follow these steps:
- Find Your Model Name: Look at the front of your calculator. The model is usually printed at the top (e.g., “TI-84 Plus CE”, “Casio fx-9750GII”).
- Enter the Model: Type the model name into the input field above. You don’t need to be exact with capitalization or spacing.
- Review the Results: The tool will instantly give you one of three results:
- ALLOWED: Your calculator is permitted.
- PROHIBITED: Your calculator is not allowed.
- CHECK: Your model might be allowed, but you need to verify it doesn’t have specific features (like CAS). This often applies to models with similar names but different capabilities.
- Check Key Details: The “intermediate values” section provides more context, explaining the calculator’s category and CAS status, helping you understand why it received that specific ruling. This is vital when considering which calculators you can use on the SAT.

Key Factors That Affect SAT Calculator Rules
The policy on calculators you can use on the SAT is influenced by several factors, all aimed at maintaining a fair and standardized testing environment. Understanding these can provide deeper insight into the SAT calculator policy.
1. Computer Algebra System (CAS)
This is the most significant factor. A CAS can automate complex algebraic steps, which tests skills the SAT is designed to measure directly. Banning them ensures all students solve problems with their own abilities.
2. Communication Features
Any feature that allows communication with other devices or the internet (Wi-Fi, Bluetooth) is banned. This prevents any possibility of receiving outside help during the exam.
3. Computer-like Features
Features like QWERTY keyboards, stylus input, or the ability to store large documents blur the line between a calculator and a computer. To keep the focus on mathematical computation, these are prohibited.
4. Power Source
Only battery-operated calculators are allowed. This rule avoids the logistical and safety issues of having power cords running through a test center.
5. Physical Size and Display
Calculators with very large or raised displays might require special seating to prevent other test-takers from seeing your screen. This is at the discretion of the test proctor.
6. Test Section
It’s crucial to remember that calculators are only permitted during the Math-Calculator section. Using one on the Reading and Writing section will lead to dismissal. This is a core part of the rules for calculators you can use on the SAT.
Frequently Asked Questions (FAQ)
1. Can I use the calculator on my phone or smartwatch?
No. All smart devices, including phones, smartwatches, and tablets, are strictly prohibited. You must use a separate, approved handheld calculator.
2. What is the difference between a scientific and a graphing calculator?
A scientific calculator handles trigonometric functions, logarithms, and exponents. A graphing calculator does all that plus it can plot equations on a coordinate plane. Most graphing calculators (without CAS) and all scientific calculators are among the calculators you can use on the SAT.
3. Is the TI-84 Plus CE allowed on the SAT?
Yes, the TI-84 Plus CE is one of the most popular and fully approved calculators for the SAT. It does not have CAS functionality. Check out our guide on using the TI-84 on SAT.
4. What happens if I bring a prohibited calculator to the test?
You will not be allowed to use it. The test proctor will confiscate it for the duration of the test, and you will have to take the math section without a calculator. It is your responsibility to bring an approved device.
5. Do I have to clear the memory on my calculator?
The College Board requires that you remove any stored programs or documents that have algebra functionality. It’s a good practice to clear your calculator’s RAM before the test.
6. Should I buy a new calculator for the SAT?
Not necessarily. The best calculator is one you are familiar with. If you already own an approved model, practice with it. If you need to buy one, choose a standard, approved model and spend time learning its functions before test day. The best calculator for SAT math is the one you know how to use efficiently.
7. Can two students share a calculator?
No. Sharing calculators is explicitly forbidden under the SAT graphing calculator rules. Each student must bring their own.
8. Are there any prohibited SAT calculators I should definitely avoid?
Yes. Avoid any model with “CAS” in the name (like TI-Nspire CX CAS, HP Prime), models with QWERTY keyboards, and older models like the TI-89 or TI-92.
