What is what kinds of calculators can be used on the sat?
Understanding what kinds of calculators can be used on the sat is one of the most critical aspects of test preparation. The College Board has strict guidelines to ensure fairness across all test centers. Generally, all scientific calculators and most graphing calculators are permitted, while devices with communication capabilities or QWERTY keyboards are strictly forbidden.
Who should use this information? Every student planning to take the SAT should verify their device months in advance. A common misconception is that you don’t need a calculator because the test is “calculator optional.” However, while you *can* solve everything by hand, knowing what kinds of calculators can be used on the sat and bringing a high-performance graphing calculator can save you up to 30% of the time on the Math section.
Another myth is that “more expensive means better.” While a TI-Nspire CX II CAS is powerful, if a student doesn’t know how to navigate its menus, a simpler TI-84 Plus might actually lead to a higher score.
what kinds of calculators can be used on the sat Formula and Mathematical Explanation
The “formula” for calculator approval is binary: either it meets the hardware constraints or it does not. The mathematical efficiency of your device on the SAT is calculated based on its ability to process complex functions, visualize graphs, and solve systems of equations numerically.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Graphing Capability | Ability to plot functions | Binary (0 or 1) | 0 – 1 |
| Processing Speed | Equation solving speed | MIPS | 1 – 100 |
| Screen Resolution | Clarity of data plots | Pixels | 96×64 – 320×240 |
| Allowed Features | No QWERTY/Wireless | Pass/Fail | Standardized |

Practical Examples (Real-World Use Cases)
Example 1: The TI-84 Plus User
A student brings a TI-84 Plus. According to the rules of what kinds of calculators can be used on the sat, this graphing calculator is permitted. On a question involving a system of three linear equations, the student uses the ‘Matrix’ function.
Input: Equation coefficients.
Output: Instant solution.
Interpretation: The student saved 90 seconds compared to substitution by hand.
Example 2: The Forbidden Device
A student brings a tablet with a calculator app. Since it has wireless capabilities and a touchscreen interface, it violates the what kinds of calculators can be used on the sat policy.
Input: Tablet device.
Output: Prohibited.
Interpretation: The student must take the test without a calculator or use the built-in Desmos calculator (if taking the Digital SAT).
How to Use This what kinds of calculators can be used on the sat Calculator
- Select your calculator brand from the dropdown menu.
- Choose the category: Graphing, Scientific, or Four-Function.
- Check any boxes that apply to your device (e.g., if it has a QWERTY keyboard).
- Input your proficiency level (how well you know the buttons!).
- Review the Status Result: “Permitted” means you are good to go; “Banned” means you need a new device.
- Check the Efficiency Rating to see how much of a competitive edge your device provides.
Key Factors That Affect what kinds of calculators can be used on the sat Results
- Keyboard Layout: Devices with “typewriter-like” QWERTY keyboards are strictly prohibited. This is to prevent students from typing out notes or long-form formulas.
- Communication Capabilities: Any device that can access the internet, has Bluetooth, or cellular data is banned to prevent cheating and external communication.
- Power Source: Calculators must be battery-operated. You cannot plug your calculator into a wall outlet during the exam, so what kinds of calculators can be used on the sat must be self-powered.
- Screen Technology: While most screens are fine, those requiring a stylus are generally not allowed as they often signify a PDA or tablet-style device.
- Graphing Functions: Graphing calculators are the “Gold Standard” for what kinds of calculators can be used on the sat because they allow for visual verification of intersections and zeros.
- Internal Memory: While you can have programs, they cannot be used to store test questions. Proctors may clear your memory, so always have your essential formulas memorized.
Frequently Asked Questions (FAQ)
1. Can I use the TI-Nspire CAS on the SAT?
Yes, the TI-Nspire CAS and CX CAS are permitted. Unlike the ACT, the SAT allows Computer Algebra System (CAS) calculators.
2. What kinds of calculators can be used on the sat if I am taking the Digital SAT?
On the Digital SAT, a version of the Desmos graphing calculator is built directly into the testing interface, but you are still allowed to bring your own approved handheld device.
3. Can I bring two calculators?
Yes, you can bring a backup. However, only one may be on your desk at a time.
4. Are scientific calculators enough for a high score?
While sufficient, scientific calculators lack the visual plotting of what kinds of calculators can be used on the sat that help catch errors in geometry and algebra.
5. Is the TI-89 allowed?
Yes, the TI-89 is on the approved list despite its advanced features.
6. Can I use a calculator with a stylus?
Generally, no. Devices that *require* a stylus are prohibited.
7. Does the proctor check the calculator model?
Yes, proctors are trained to identify what kinds of calculators can be used on the sat and will inspect devices before the test begins.
8. What happens if my calculator dies?
Test centers do not provide batteries or chargers. If your device dies, you must complete the test by hand or use the built-in digital tool.
