Commonly Prohibited Calculator Features
The College Board prohibits any calculator with the following features. Ensure your device does not have any of these before test day.
| Feature | Description | Reason for Prohibition |
|---|---|---|
| QWERTY Keyboard | A typewriter-style keyboard (e.g., TI-92, HP-49G+). | Prevents storing notes or communication. |
| Computer Algebra System (CAS) | Software that manipulates algebraic expressions symbolically (e.g., TI-Nspire CAS). | Provides an unfair advantage by solving algebra problems automatically. |
| Wireless/Internet/Bluetooth | Any feature that allows communication with other devices. | Prevents cheating and accessing outside information. |
| Stylus or Pen Input | Touch-screen devices that use a stylus (e.g., Palm Pilots). | Considered a mini-computer with note-taking ability. |
| Needs Electrical Outlet | Calculators that are not battery-operated. | Logistical and safety issues in testing rooms. |
| Makes Noise | Any audible sounds from key presses or alerts. | Distracts other test-takers. |
What is the SAT Calculator Policy?
The SAT Calculator Policy outlines the rules for using calculators during the SAT exam. Understanding this policy is crucial for a smooth test day experience. While the digital SAT, taken on the Bluebook⢠app, includes an embedded Desmos graphing calculator for the entire Math section, students are still permitted to bring their own approved calculator. The primary goal of the policy is to ensure fairness and prevent any student from having an unfair advantage through technology. This means that while most graphing and scientific calculators are allowed, any device with features that can solve algebraic equations symbolically (CAS), communicate wirelessly, or function like a computer are strictly forbidden. Knowing if your device complies with the SAT Calculator Policy is a key part of your test preparation.
Who Should Use the Calculator?
Every student taking the SAT Math section should be prepared to use a calculator. For the digital SAT, you have the choice between the powerful built-in Desmos calculator or your own handheld device. If you’ve trained extensively with a specific calculator like a TI-84 Plus, it’s often best to use that familiar tool. The SAT Calculator Policy is designed to give you options, not to restrict you. Familiarity can save precious seconds on test day. However, it’s wise to also practice with the Desmos tool as a backup, in case your personal calculator malfunctions.
Common Misconceptions
A major misconception is that you *need* the most expensive graphing calculator to succeed. This is false. Every question on the SAT can be solved without a calculator. A calculator is a tool to save time and reduce calculation errors, not a substitute for understanding mathematical concepts. Another myth is that all graphing calculators are allowed. This is dangerously incorrect; calculators with CAS functionality are explicitly banned under the SAT Calculator Policy. Always check your model against the official list or use our policy checker above.
SAT Calculator Policy Formula and Explanation
While not a mathematical formula, the logic for determining calculator eligibility can be expressed as a decision-making process. The SAT Calculator Policy is based on a series of checks. The core principle is: a calculator is a tool for computation, not for solving problems or storing information.
The evaluation can be broken down into these steps:
- Section Check: Is the current test section the Math section? If no, the calculator is not allowed.
- Feature Check: Does the calculator have any prohibited features (CAS, QWERTY, Wi-Fi, etc.)? If yes, it is not allowed.
- Model Check: Is the calculator model on the explicitly prohibited list? If yes, it is not allowed.
- Approval: If the calculator passes all the above checks, it is permitted for use.
Variables Table
| Variable | Meaning | Permitted Values | Typical Range |
|---|---|---|---|
| Test Section | The section of the SAT being taken. | Math, Reading, Writing | Only ‘Math’ allows calculators. |
| Calculator Type | The category of the calculator. | Graphing, Scientific, 4-Function | Most graphing and scientific are okay. |
| CAS Functionality | Computer Algebra System presence. | Yes / No | Must be ‘No’. |
| QWERTY Keyboard | Presence of a typewriter-style keyboard. | Yes / No | Must be ‘No’. |
Practical Examples (Real-World Use Cases)
Example 1: Student with a TI-84 Plus
- Inputs: Test Section = Math (Calculator), Calculator Model = “TI-84 Plus”
- Analysis: The TI-84 Plus is a standard graphing calculator. It does NOT have a QWERTY keyboard and it is a non-CAS model. It is one of the most common and widely accepted calculators.
- Output: The calculator is ALLOWED. This device is fully compliant with the SAT Calculator Policy for the Math section.
Example 2: Student with a TI-Nspire CX II CAS
- Inputs: Test Section = Math (Calculator), Calculator Model = “TI-Nspire CX II CAS”
- Analysis: The model name explicitly contains “CAS,” which stands for Computer Algebra System. This feature is explicitly banned by the College Board.
- Output: The calculator is NOT ALLOWED. Even though it’s a graphing calculator, the CAS functionality violates the SAT Calculator Policy.

Key Factors That Affect SAT Calculator Policy Results
Several critical factors determine whether a calculator is compliant with the SAT Calculator Policy. Understanding these will help you choose the right tool for test day.
- Computer Algebra System (CAS): This is the most significant factor. CAS-enabled calculators can perform symbolic algebra, giving a clear advantage. They are always banned. Models like the TI-89, TI-Nspire CAS, and HP Prime are prohibited for this reason.
- QWERTY Keyboards: Any calculator with a typewriter-like keyboard is forbidden. This rule prevents students from storing text notes.
- Communication Capabilities: Devices with Wi-Fi, Bluetooth, or infrared ports are not allowed. This is a core tenet of the SAT Calculator Policy to prevent cheating.
- Power Source: Calculators must be battery-powered. Devices that need to be plugged into an electrical outlet are not permitted.
- Physical Size and Noise: Calculators with oversized displays (characters one inch or larger) or that make noise may lead to you being moved or your device being disallowed to prevent distracting others.
- Digital SAT vs. Paper SAT: For the digital SAT, a powerful Desmos calculator is built into the testing software for the entire math section. This reduces the dependency on a handheld device but doesn’t change the rules for bringing your own. For the paper SAT, there are distinct “calculator” and “no-calculator” math sections.
Frequently Asked Questions (FAQ)
