Visual Guide to SAT Calculator Policy
| Calculator Status | Example Models | Key Reason |
|---|---|---|
| ✅ Allowed | TI-84 Plus, TI-Nspire (Non-CAS), Casio fx-9750GII | Standard graphing/scientific functionality, no CAS. |
| ❌ Prohibited | TI-89 Titanium, TI-Nspire CX II CAS, HP Prime | Contains a Computer Algebra System (CAS). |
| ❌ Prohibited | Laptops, Mobile Phones, Smartwatches | Has wireless communication, QWERTY keyboard, or is not a dedicated calculator. |
This table shows common examples of allowed and prohibited calculators. The primary restriction relates to Computer Algebra Systems (CAS). This is a core part of the policy for calculators allowed on the SAT.

Understanding the Policy for Calculators Allowed on the SAT
What is the SAT Calculator Policy?
The SAT calculator policy is a set of rules established by the College Board that dictates which types of calculators are permitted for use during the Math section of the SAT exam. The primary goal of this policy is to ensure fairness and prevent any student from having an unfair technological advantage. It defines the features, models, and types of calculators allowed on the SAT, as well as those that are strictly forbidden. Understanding these rules is critical for test-day success and avoiding disqualification.
This policy applies to all students taking the SAT. Common misconceptions are that any graphing calculator is fine, or that the most expensive calculator is the best. In reality, some advanced calculators with Computer Algebra Systems (CAS) are banned. For information on the digital SAT calculator rules, students should know a Desmos calculator is built into the testing software.
SAT Calculator Rules and Mathematical Explanation
There isn’t a mathematical “formula” for determining if a calculator is allowed, but rather a set of clear, logical rules. The decision is based on the calculator’s built-in functionality. The most important rule is the prohibition of calculators with a Computer Algebra System (CAS). A CAS can perform symbolic manipulation (like factoring x²-4 into (x-2)(x+2)), which goes beyond the numerical calculations the SAT intends to test.
Here’s a breakdown of the key rules that determine which calculators are allowed on the SAT:
| Feature / Rule | Meaning | Status on SAT | Typical Range/Example |
|---|---|---|---|
| Computer Algebra System (CAS) | Ability to manipulate symbolic algebraic expressions. | Prohibited | TI-89, HP Prime, TI-Nspire CAS |
| QWERTY Keyboard | A computer-style keyboard. | Prohibited | Any device with a text keyboard. |
| Wireless/Internet Access | Bluetooth, Wi-Fi, or cellular connectivity. | Prohibited | Smartphones, smartwatches, tablets. |
| Stylus/Pen Input | Requires a stylus for operation. | Prohibited | Casio ClassPad series. |
| Needs External Power | Must be plugged into an outlet to work. | Prohibited | Desktop computers, laptops. |
| Graphing Capability | Can plot functions and analyze graphs. | Allowed (if non-CAS) | TI-84 Plus, Casio fx-9750GII |
Practical Examples (Real-World Use Cases)
Let’s look at two common scenarios students face when checking the list of calculators allowed on the SAT.
Example 1: Student with a TI-84 Plus CE
- Input: The student enters “TI-84 Plus CE” into the calculator checker.
- Logic: The tool recognizes this model. It is a very popular, non-CAS graphing calculator. It is on the approved list.
- Output: The result is “Allowed”. The interpretation is that this calculator is perfectly acceptable for the SAT Math section. The student can and should practice with this device. It is one of the most common SAT math calculator models.
Example 2: Student with a TI-89 Titanium
- Input: The student enters “TI-89 Titanium”.
- Logic: The tool identifies this model as having a Computer Algebra System (CAS). The College Board explicitly prohibits calculators with CAS.
- Output: The result is “Prohibited”. The student is advised that they cannot bring this calculator to the test center. They will need to acquire an approved model, like one from the TI-83/84 series or a comparable non-CAS device.
How to Use This Calculator Checker
This tool makes it simple to determine if you have one of the calculators allowed on the SAT. Follow these steps:
- Find Your Model Number: Look at the top of your calculator to find the exact model (e.g., “TI-83 Plus”, “Casio fx-991EX”).
- Enter the Model: Type the model name into the input field above.
- Check the Result: Click the “Check Eligibility” button. The tool will instantly provide one of three results: Allowed, Prohibited, or Check Manually.
- Read the Details: The results area will explain why your calculator received that status, often referencing the specific rule (e.g., “This model has a Computer Algebra System”).
- Make a Decision: If your calculator is prohibited, you must find an alternative. Refer to the College Board’s official list or our examples of approved SAT calculators for guidance.
Key Factors That Affect Calculator Acceptance
Several features determine whether a calculator is approved. Understanding these factors is key to knowing the policy for calculators allowed on the SAT.
- Computer Algebra System (CAS): This is the most significant factor. CAS functionality is banned because it solves algebraic problems symbolically, which is considered an unfair advantage.
- Internet/Wireless Connectivity: Any device that can communicate with other devices or the internet is strictly forbidden to prevent cheating. This includes phones, tablets, and smartwatches.
- Keyboard Type: Calculators with QWERTY (computer-style) keyboards are not allowed.
- Power Source: The calculator must be battery-operated. Devices that need to be plugged into an electrical outlet are prohibited.
- Stylus or Touch Screen: Calculators that require a pen or stylus for input are generally not allowed.
- Audio/Video/Camera Functions: Any device capable of recording or playing audio or video is banned. This is another reason why your phone can’t be your calculator.
Staying informed about the official College Board calculator policy ensures you are well-prepared for test day.
Frequently Asked Questions (FAQ)
It depends. The TI-Nspire CX (non-CAS) and TI-Nspire CX II (non-CAS) are allowed. However, the TI-Nspire CAS and TI-Nspire CX II CAS are prohibited. Check the top of your calculator; if it says “CAS”, it’s not allowed.
Yes, generally all scientific calculators are permitted as they do not have the advanced prohibited features like CAS or graphing capabilities that are scrutinized.
If a proctor identifies your calculator as a prohibited model, you will not be allowed to use it. You may have to take the math section without a calculator, or your test could be invalidated.
Yes, proctors may ask you to clear the memory on your calculator before the test begins to ensure no notes or formulas are stored. Familiarize yourself with how to do this on your specific model.
Absolutely. The entire TI-84 series (Plus, CE, etc.) remains one of the most popular and universally accepted choices for the SAT.
No. Phones, smartwatches, tablets, and laptops are explicitly banned for use as calculators during the exam. Your device must be a dedicated, handheld calculator.
For the Digital SAT, an amazing graphing calculator (Desmos) is built directly into the testing application (Bluebook). You can still bring your own approved handheld calculator if you prefer. The list of calculators allowed on the SAT remains the same.
Yes, they are allowed, but they are not recommended. They lack scientific functions like exponents and logs which can be very helpful on the SAT Math section. For more info see the what calculators are not allowed on the SAT list.
