SAT Calculator Policy & Approved Model Checker
Instantly verify if your calculator is permitted on the SAT. This tool checks your model against the official College Board SAT Calculator Policy to help you prepare for test day.
Understanding the Official SAT Calculator Policy
The College Board maintains a strict SAT Calculator Policy to ensure fairness and test integrity. Not all calculators are created equal, and some models with advanced functionalities could provide an unfair advantage. Using a prohibited device, even accidentally, can lead to dismissal from the test and cancellation of your scores. This guide and our checker tool are designed to help you navigate the official SAT Calculator Policy and arrive on test day confident and prepared.
| Calculator Type | Permitted? | Common Examples |
|---|---|---|
| Most Graphing Calculators | Yes | TI-84 Plus, TI-Nspire (non-CAS), Casio FX-9750GII |
| All Scientific Calculators | Yes | TI-30X, Casio FX-115ES |
| Basic Four-Function | Yes | Any basic calculator (not recommended) |
| Calculators with CAS | No | TI-89, TI-Nspire CAS, HP Prime |
| Calculators with QWERTY keyboard | No | TI-92, Casio ClassPad |
| Phones, Tablets, Laptops | No | iPhone, Android devices, computers |
What is the SAT Calculator Policy?
The SAT Calculator Policy is a set of rules specifying which calculators are allowed for use on the math section of the SAT. The primary goal is to prevent any student from having a technological advantage. The policy explicitly bans devices with features like a Computer Algebra System (CAS), internet access, or a typewriter-style (QWERTY) keyboard. While you can bring your own approved calculator, the digital SAT also includes a built-in Desmos graphing calculator, which is always compliant with the SAT Calculator Policy.
Prohibited Features and a Breakdown of the Rules
Instead of listing every allowed model, the College Board defines the SAT Calculator Policy by listing prohibited features. If your calculator has any of the following, it is NOT allowed:
| Prohibited Feature | Explanation | Reasoning |
|---|---|---|
| Computer Algebra System (CAS) | Can solve algebraic equations symbolically (e.g., solve ‘x + 2y = 4’ for ‘x’). | Automates algebra, which is a skill being tested. |
| QWERTY Keyboard | A typewriter-style keyboard. | Poses a security risk for storing notes. |
| Wireless / Internet / Bluetooth | Any feature that allows communication with other devices. | Prevents cheating and unauthorized access to information. |
| Requires Power Cord | Must be plugged into an electrical outlet to function. | Test centers are not equipped to provide power to students. |
| Makes Noise / Prints | Calculators with sound or paper tape features. | Distracts other test-takers. |
| Stylus / Pen-Input | Devices that use a stylus for operation. | Considered a security risk similar to a QWERTY keyboard. |
Practical Examples (Real-World Use Cases)
Example 1: A Student with a TI-84 Plus
A student enters “TI-84 Plus” into the calculator checker. The tool’s logic identifies this model. It does not contain “CAS,” “89,” or “92.” It has no QWERTY keyboard. The result is “Approved.” The student can be confident bringing this popular and fully compliant calculator to the test, knowing it adheres to the SAT Calculator Policy.
Example 2: A Student with a TI-Nspire CX II CAS
Another student types “TI-Nspire CX II CAS.” The logic immediately flags the “CAS” in the name. The tool returns a “Prohibited” result, explaining that calculators with a Computer Algebra System are not allowed under the SAT Calculator Policy. This student now knows they must find a different, non-CAS calculator for the exam.
How to Use This SAT Calculator Policy Checker
Using this tool is straightforward and designed for quick verification.
- Find Your Model Number: Look at the top of your calculator. The model number is usually printed clearly (e.g., “TI-84 Plus CE”).
- Enter the Model: Type the full model name into the input field above.
- Review the Result: The tool will instantly provide a status: Approved, Prohibited, or Warning. The result is based on the known rules of the SAT Calculator Policy.
- Read the Explanation: The result card will explain *why* your calculator received that status, referencing specific prohibited features if applicable.
Key Factors That Affect Your Calculator Choice
Choosing the right calculator involves more than just checking a list. Here are six factors to consider beyond simple compliance with the SAT Calculator Policy.
- Familiarity: The best calculator is the one you know how to use. Don’t switch to a new, complicated model right before the test. Wasting time trying to find a function is a common mistake.
- Graphing vs. Scientific: Graphing calculators are powerful for visualizing functions and solving equations graphically. Scientific calculators are sufficient but may require more steps. The SAT Calculator Policy allows both.
- Built-in Desmos Calculator: The digital SAT includes a fantastic Desmos graphing calculator. It’s powerful and always available. Practicing with the Desmos tool can eliminate the need to bring your own device.
- Battery Life: Your calculator must be battery-powered. Make sure you have fresh batteries before test day. Power cords are not allowed.
- Test Center Discretion: Proctors have the final say. A calculator with a large, raised display might cause you to be reseated. Ensure your device is standard and inconspicuous.
- Cost vs. Benefit: You do not need the most expensive calculator. A mid-range scientific or graphing calculator that you are comfortable with is far more valuable than a high-end model you don’t understand.
Frequently Asked Questions (FAQ)
No. Phones, smartwatches, and any device with communication capabilities are strictly forbidden under the SAT Calculator Policy. They must be put away and turned off.
You will have to continue the test without it. Test centers do not provide batteries. It is your responsibility to ensure your calculator is fully functional. Bringing a backup calculator (that is also on the approved list) is a good idea.
It depends. The standard “TI-Nspire” and “TI-Nspire CX” models are allowed. However, any model with “CAS” in the name (like the “TI-Nspire CX CAS”) is prohibited. This is a critical distinction in the SAT Calculator Policy.
No, but it is highly recommended. All questions can be solved without a calculator, but a graphing calculator can solve certain problems (like finding intersections of functions) much faster. A scientific calculator is also a valid option.
The SAT Calculator Policy is the same, but the digital SAT includes a built-in Desmos graphing calculator. You can use the built-in tool, your own approved calculator, or both.
The proctor will likely confiscate the device, and you will be dismissed from the test. Your scores for that test date will be canceled.
Yes, you are allowed to bring a backup calculator. However, it must also adhere to the SAT Calculator Policy, and you must store it under your desk when not in use.
The College Board website maintains the definitive SAT Calculator Policy. Our tool is based on this policy, but you should always consider the official source as the final authority.
