|---|---|---|
| Texas Instruments | TI-83 Plus, TI-84 Plus (all versions), TI-Nspire CX | TI-89, TI-92, TI-Nspire CAS (all versions) |
| Casio | fx-9750GIII, fx-9860GII, fx-CG50 | ClassPad series (300, 330, 400, II), Algebra fx 2.0 |
| HP | HP 39gII, HP 50g (without CAS) | HP Prime, HP 48GII |
| General Features | Scientific, Four-Function, Graphing | QWERTY keyboard, wireless, requires power outlet, paper tape |
Calculator Types Allowed on the SAT
What is the SAT Calculator Policy?
The SAT calculator policy is a set of rules established by the College Board to ensure fairness and test security during the SAT exam. This policy specifies which calculators are permitted for use on the Math section of the test and which are prohibited. The primary goal is to prevent any student from having an unfair advantage through the use of advanced computational tools. The rules apply to all students taking the SAT, whether it’s the digital version with its built-in calculator or those bringing their own device.
The core of the calculators allowed in sat policy revolves around prohibiting devices with a Computer Algebra System (CAS). CAS functionality allows calculators to manipulate algebraic expressions symbolically, solve equations with exact answers, and perform other advanced calculus operations that go beyond the scope of what the SAT is designed to assess. Familiarity with the SAT calculator policy is crucial for a smooth test day experience.
Who Should Use This Policy?
Any student preparing to take the SAT or a PSAT-related assessment must be familiar with this policy. It is your responsibility to bring an approved calculator to the test center; proctors will not provide them. Understanding which calculators are allowed can save you from having your device confiscated or, in worst-case scenarios, your scores canceled. This guide and checker are designed to help students, parents, and educators quickly verify if a specific calculator meets the current requirements.
Common Misconceptions
A frequent misconception is that all graphing calculators are banned. This is incorrect. Most graphing calculators are perfectly acceptable, provided they do not have CAS functionality. Another myth is that you need the most expensive calculator. A basic scientific calculator or a familiar graphing calculator like the TI-84 Plus is more than sufficient. You are also allowed to use the built-in Desmos graphing calculator provided in the digital SAT platform, which is an excellent and fully compliant tool.
Understanding the SAT Calculator Rules
Instead of a single mathematical formula, the SAT calculator policy is a logical framework based on calculator features. The decision to allow or prohibit a device is determined by its capabilities. Understanding this logic is key to ensuring your device is compliant with the regulations for calculators allowed in sat.
The central rule is the prohibition of calculators with a Computer Algebra System (CAS). A CAS can perform symbolic manipulation, which is a significant advantage not available to all test-takers. The College Board has updated its policy to explicitly ban all CAS calculators to maintain a level playing field.
Key Feature Evaluation Table
| Feature / Capability | Meaning | Status | Typical Models |
|---|---|---|---|
| Computer Algebra System (CAS) | Can manipulate symbolic expressions (e.g., factor `x^2-1`). | PROHIBITED | TI-Nspire CAS, HP Prime, TI-89 |
| Graphing | Can plot functions and analyze graphs. | ALLOWED | TI-84 Plus, Casio fx-9750GIII, TI-Nspire CX (non-CAS) |
| Scientific Functions | Has trigonometric (sin, cos, tan) and logarithmic (log) functions. | ALLOWED | TI-30X, Casio fx-115ES |
| QWERTY Keyboard | A typewriter-style keyboard for text input. | PROHIBITED | Some older Sharp models, PDA-like devices |
| Wireless Communication | Includes Wi-Fi, Bluetooth, or infrared data ports. | PROHIBITED | Smartphones, tablets, smartwatches |
| External Power | Requires a power cord to operate. | PROHIBITED | Laptops, desktop calculators |
Practical Examples of the SAT Calculator Policy
Example 1: The Compliant Student
Scenario: Maria owns a TI-84 Plus CE. She enters “TI-84 Plus CE” into the calculator checker.
Inputs & Outputs:
- Input Model: TI-84 Plus CE
- Result: ALLOWED
- Explanation: The TI-84 Plus series is one of the most common graphing calculators and is explicitly allowed because it does not have a CAS. It is a powerful tool for the SAT Math section.
Interpretation: Maria can confidently bring her calculator to the test. She should ensure it has fresh batteries as power cords are not permitted.
Example 2: The Prohibited Calculator
Scenario: David has a TI-Nspire CX II CAS from his calculus class. He checks its eligibility.
Inputs & Outputs:
- Input Model: TI-Nspire CX II CAS
- Result: NOT ALLOWED
- Explanation: This calculator is prohibited because the “CAS” in its name stands for Computer Algebra System. The SAT calculator policy strictly forbids all CAS models.
Interpretation: David cannot use this calculator. He must find a non-CAS alternative, such as a TI-84 or a scientific calculator, or plan to use the built-in Desmos calculator during the digital exam.
How to Use This SAT Calculator Policy Checker
Using this tool to determine if your device is one of the calculators allowed in sat is simple and fast. Follow these steps to get an immediate and accurate result based on the current College Board guidelines.

Key Factors That Affect SAT Calculator Policy Results
Several critical factors determine whether a calculator is permitted. Understanding these will help you navigate the SAT calculator policy effectively.
1. Computer Algebra System (CAS)
This is the most important factor. Calculators that can perform symbolic algebra are banned. This is because they provide a significant advantage in solving complex algebraic problems, which is against the principle of a standardized test. Always check if your calculator model name contains “CAS”.
2. QWERTY Keyboard
Any device with a typewriter-style (QWERTY) keyboard is prohibited. This rule prevents the use of devices that could store notes or be used for communication.
3. Wireless and Internet Connectivity
Calculators with any form of wireless communication, including Bluetooth, Wi-Fi, or infrared, are strictly forbidden to maintain test security and prevent cheating. This includes smartphones, tablets, and smartwatches.
4. Power Source
Only battery-operated calculators are allowed. Devices that require an electrical outlet are not permitted in the testing room. Ensure your calculator has fresh batteries before test day.
5. Noise and Printing
Calculators that make noise or print to paper tape are banned as they can be disruptive to other test-takers.
6. Display Type
Calculators with oversized characters (1 inch or larger) or a raised display that might be visible to others may lead to you being moved to a different seat at the proctor’s discretion.
Frequently Asked Questions (FAQ) about the SAT Calculator Policy
No. While most graphing calculators are allowed, any model with a Computer Algebra System (CAS) is strictly prohibited. For example, the TI-Nspire CX is allowed, but the TI-Nspire CX CAS is not.
The test proctor will not allow you to use it. You will have to take the Math section without a calculator or use the built-in digital one if available. In some cases, bringing a prohibited device could lead to dismissal.
No, it is not required. A scientific calculator is sufficient for the test. However, a graphing calculator can be a very helpful tool for certain problems if you know how to use it efficiently. The digital SAT also provides a powerful built-in Desmos graphing calculator.
Yes, all versions of the TI-84 Plus (including Plus, Silver Edition, CE) are explicitly allowed as they are non-CAS graphing calculators. This is one of the most popular choices for the SAT.
No. Phones, smartwatches, and any other device with communication capabilities are strictly prohibited. Using one will result in immediate dismissal and cancellation of your scores.
A non-CAS calculator gives numerical answers (e.g., 2.5). A CAS calculator can give symbolic answers (e.g., 5/2) and manipulate variables and expressions, like factoring `x^2 – 4` into `(x-2)(x+2)`.
Yes, the policy was updated to explicitly ban all calculators with CAS functionality to ensure fairness as this technology became more widespread.
No. Sharing calculators is not allowed. Each student must bring their own approved calculator.
