SAT Calculator Policy Checker
Can I Use My Calculator on the SAT?
The College Board has specific rules about which calculators are permitted. Use this tool to check if your calculator’s features are allowed on the SAT Math section.
Like a computer keyboard (e.g., TI-92 Plus).
Calculators that can manipulate variables and equations (e.g., TI-Nspire CAS, HP Prime).
Any feature that can connect to the internet or other devices.
General-purpose computing devices are not allowed.
Calculators must be battery-operated.
Any audible or printing features must be disabled or are prohibited.
Use of a stylus is not permitted (e.g., Sharp EL-9600).
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 integrity during the exam. The core question for students is often, “can i use my calculator on the sat?” The answer is yes, but only if it’s an approved device. The policy dictates which types of calculators (graphing, scientific, four-function) are allowed and, more importantly, which features are strictly prohibited. These rules prevent any student from having an unfair advantage through access to features like symbolic equation solving (CAS), internet connectivity, or text-storage capabilities. Understanding this policy is a critical part of preparing for test day.
SAT Calculator Rules: The Official Logic
The “formula” for whether you can use your calculator on the SAT is a logic-based assessment of its features. A calculator is generally permitted if it is a standard scientific or graphing calculator. However, it is immediately disqualified if it has certain prohibited features. The logic is a series of checks: if any prohibited feature is present, the device is not allowed.
| Variable (Feature) | Meaning | Unit | Typical Range |
|---|---|---|---|
| Computer Algebra System (CAS) | Ability to manipulate algebraic expressions symbolically. | Boolean (Yes/No) | No (Prohibited) |
| QWERTY Keyboard | A text-based keyboard layout. | Boolean (Yes/No) | No (Prohibited) |
| Wireless Capability | Wi-Fi, Bluetooth, Cellular, or Infrared data ports. | Boolean (Yes/No) | No (Prohibited) |
| External Power | Requirement of an electrical outlet to function. | Boolean (Yes/No) | No (Prohibited) |
| Computing Device | Is a phone, tablet, laptop, or smartwatch. | Boolean (Yes/No) | No (Prohibited) |
| Noise/Printing | Makes audible sounds or has a paper tape. | Boolean (Yes/No) | No (Prohibited) |
Practical Examples (Real-World Use Cases)
Example 1: The Standard Graphing Calculator (TI-84 Plus)
A student has a Texas Instruments TI-84 Plus. They use the checker and select ‘No’ for all prohibited features. The result is “Permitted.” The TI-84 Plus is a perfect example of a powerful graphing calculator that is allowed because it lacks a CAS, QWERTY keyboard, or wireless functions. It is one of the most common and recommended calculators for the SAT.
Example 2: The Prohibited Device (A Smartphone)
A student wants to know if they can use the calculator app on their smartphone. They check the box for “Is it a phone, tablet, laptop, or smartwatch?” and “Does it have wireless, Bluetooth, or cellular capability?”. The result is immediately “Not Permitted.” This is because smartphones are general-purpose computing devices with internet access, which is strictly forbidden by the SAT policy to prevent cheating.
How to Use This SAT Calculator Policy Checker
This tool simplifies the process of figuring out if you can use your calculator on the SAT. Follow these simple steps:
- Inspect Your Calculator: Look at your calculator for the features listed above.
- Check the Boxes: For each feature your calculator possesses, click the corresponding checkbox.
- Review the Result: The tool provides an instant result: “Permitted” or “Not Permitted.”
- Understand the Details: The secondary results section will list exactly which prohibited features were detected, so you know the specific reason for the decision. For more help with test day, check out this guide on the SAT test day checklist.
Key Factors That Affect SAT Calculator Approval
- Computer Algebra System (CAS): This is a major disqualifier. CAS calculators can solve equations symbolically (e.g., show ‘x=2y’ instead of a decimal), which is considered an unfair advantage. The College Board officially banned CAS calculators starting in 2025.
- QWERTY Keyboards: Any device with a typewriter-style keyboard is prohibited to prevent the storage and use of notes.
- Communication Technology: Any calculator that can communicate with other devices (via Wi-Fi, Bluetooth, etc.) is banned.
- Power Source: Calculators must be battery-powered. Those that require an electrical outlet are not allowed in the testing room.
- Device Type: The device must be a dedicated calculator. Laptops, tablets, smartwatches, and phones are never allowed. The digital SAT includes a built-in Desmos graphing calculator, which you can learn about with these graphing calculator tips.
- Physical Attributes: Calculators that make noise, print on paper tape, or have oversized displays may be prohibited or require special seating arrangements.
Frequently Asked Questions (FAQ)
1. Can I use a TI-84 on the SAT?
Yes, all versions of the TI-84 Plus (including the CE) are explicitly allowed as they do not have a Computer Algebra System (CAS). It is one of the most recommended calculators.
2. What happens if I bring a prohibited calculator?
You will not be allowed to use it. If you are caught using a prohibited device during the test, you may be dismissed, and your scores will be canceled.
3. Are scientific calculators allowed on the SAT?
Yes, all standard scientific calculators are allowed on the SAT.
4. Do I have to clear my calculator’s memory?
Yes, the rules state that you may be asked to clear all saved formulas or programs before the test begins.
5. Can I use the calculator on all sections of the SAT?
For the digital SAT, you are allowed to use a calculator on the entire Math section. You cannot use it on the Reading and Writing section.
6. Is the built-in Bluebook calculator good enough?
The digital SAT provides an excellent built-in graphing calculator (a version of Desmos). It is very powerful; however, if you are more comfortable and faster with your own approved handheld calculator, it is a good idea to bring it. Explore some SAT math help strategies to decide what’s best for you.
7. What is a Computer Algebra System (CAS) and why is it banned?
A CAS can manipulate mathematical expressions symbolically—for example, factoring `x^2-1` into `(x-1)(x+1)`. This provides a significant advantage over calculators that only produce numerical answers. To ensure fairness, the College Board banned these devices.
8. My calculator has a stylus. Can I use it?
No, calculator models that use a stylus or pen-input system are allowed, but the use of the stylus itself is prohibited during the test.
