SAT Approved Calculator Checker
Is Your Calculator on the Official SAT Approved List?
Enter your calculator model name below to instantly check if it is one of the approved calculators for the SAT. The digital SAT has a built-in Desmos graphing calculator, but you are still permitted to bring your own device. Ensure your device complies with the College Board’s official policy to avoid issues on test day.
What Are Approved Calculators for the SAT?
Approved calculators for the SAT are specific handheld electronic devices that the College Board, the organization that administers the SAT, permits students to use during the Math section of the exam. While the digital SAT includes an integrated Desmos graphing calculator, students often prefer using a physical device they are familiar with. The policy is in place to ensure fairness and prevent any student from having an unfair advantage through technology.
This policy primarily targets devices with features that could compromise test integrity, such as internet connectivity, computer algebra systems (CAS), or QWERTY keyboards. Any student preparing for the SAT should verify their device against the official list of approved calculators for the SAT to ensure a smooth and stress-free test day experience.
SAT Calculator Policy and Rules Explanation
The College Board’s policy isn’t a mathematical formula but a set of rules and restrictions. The core principle is that calculators are tools for computation, not for storing information or performing symbolic algebraic manipulation. Understanding these rules is essential for anyone using our checker for approved calculators for the SAT.
The main restriction is on calculators with a Computer Algebra System (CAS). CAS functionality allows a calculator to manipulate algebraic expressions symbolically, which provides a distinct advantage not related to a student’s mathematical reasoning skills. For instance, a CAS calculator can solve for ‘x’ in an equation or factor a complex polynomial automatically.
| Rule / Feature | Status | Explanation | Typical Range / Example |
|---|---|---|---|
| Computer Algebra System (CAS) | Prohibited | Device cannot perform symbolic algebra (e.g., factor, expand, solve equations symbolically). | Models with “CAS” in the name like TI-Nspire CX II CAS are banned. |
| Graphing Capability | Permitted | Device can plot functions and analyze graphs. | Most TI-84, TI-Nspire (non-CAS), and Casio FX-9860 models. |
| Scientific Functions | Permitted | Device can compute trigonometric, logarithmic, and exponential functions. | All scientific calculators are allowed. |
| QWERTY Keyboard | Prohibited | Calculators with a typewriter-style keyboard are not allowed. | Any device that looks like a small computer. |
| Wireless/Internet | Prohibited | Device cannot have any wireless communication (Bluetooth, Wi-Fi, infrared). | Smartphones, tablets, and smartwatches. |
| Power Source | Battery Only | Calculators cannot use an electrical outlet. | Must be battery-operated (no power cords). |

Practical Examples (Real-World Use Cases)
Example 1: Checking a Common Graphing Calculator
- Student’s Situation: Maria has a TI-84 Plus CE that she has used throughout her high school math classes. She wants to confirm it’s an approved calculator for the SAT.
- Using the Checker: She types “TI-84 Plus CE” into the calculator.
- Result: The tool shows “APPROVED“. The intermediate values show its type as “Graphing” and confirms it has no CAS functionality. The explanation notes that the entire TI-83 and TI-84 series are among the most popular approved calculators for the SAT.
Example 2: Checking a Prohibited Calculator
- Student’s Situation: David received a TI-Nspire CX II CAS as a gift. It’s a powerful calculator, and he’s unsure if the “CAS” part matters.
- Using the Checker: He enters “TI-Nspire CX II CAS” into the checker.
- Result: The tool immediately returns “PROHIBITED“. The explanation clearly states that all calculators with “CAS” in their name are explicitly banned by the College Board due to their computer algebra system capabilities. David now knows he needs to find an alternative, like a non-CAS TI-Nspire CX II or a different model from the list of approved calculators for the SAT.
How to Use This Approved Calculators for the SAT Checker
- Enter the Model Name: Type the full model name of your calculator into the input field. For best results, include series information (e.g., “Plus CE”, “GIII”).
- Review the Instant Result: As you type, the tool will search its database. The primary result will show “APPROVED”, “PROHIBITED”, or “NOT FOUND”.
- Analyze the Details: The section below the main result provides key details: the calculator’s status, its general type (Graphing, Scientific), and whether it has CAS. This helps you understand why your device is or isn’t an approved calculators for the sat.
- Reset or Copy: Use the “Reset” button to clear the fields for a new search. If you want to save the result, click “Copy Results” to copy a summary to your clipboard. For more information, please see our SAT prep guide.
Key Factors That Affect Calculator Approval
The College Board’s decision to approve or prohibit a calculator is based on several factors designed to maintain a level playing field. Understanding these is crucial for selecting from the many approved calculators for the SAT.
- Computer Algebra System (CAS): This is the most significant factor. CAS can solve equations and perform symbolic algebra, which tests a calculator’s power rather than a student’s skill. This is why they are banned.
- QWERTY Keyboard: Devices with a full keyboard are prohibited because they resemble computers and could be used for storing notes.
- Wireless Communication: Any device with Wi-Fi, Bluetooth, or cellular capabilities is strictly forbidden to prevent communication during the exam. Explore our test day checklist for more tips.
- Stylus or Pen-Input: Calculators that require a stylus or have pen-input functionality are not allowed, as this feature is often associated with models that have prohibited functions.
- Power Source: Calculators that need to be plugged into an electrical outlet are banned. All approved calculators for the SAT must be battery-operated.
- Noise and Printing: Any device that makes noise or has a paper tape printer is not allowed to avoid distracting other test-takers.
Frequently Asked Questions (FAQ)
1. Are all scientific calculators approved for the SAT?
Yes, virtually all standard scientific calculators are approved calculators for the SAT. They perform the necessary trigonometric and logarithmic functions without having the prohibited CAS or communication features.
2. What’s the difference between a TI-Nspire CX II and a TI-Nspire CX II CAS?
The TI-Nspire CX II is an approved calculator for the SAT. The “CAS” model is prohibited. The only difference is the Computer Algebra System. The non-CAS version is a powerful graphing calculator, while the CAS version adds symbolic algebra features that are banned. Check our graphing calculator comparison for details.
3. Can I use my phone’s calculator app?
No. All phones, tablets, smartwatches, and laptops are strictly prohibited from being used during the test.
4. What if my calculator is not on the approved list but isn’t on the prohibited list either?
If our checker returns “Not Found,” your calculator is likely obscure or very new. In this case, you should err on the side of caution. Review its features against the prohibited list (CAS, QWERTY, etc.). If it has any of those, do not bring it. When in doubt, choose a model that is explicitly listed as one of the approved calculators for the SAT.
5. Do I have to bring a calculator for the digital SAT?
No, it’s not required. The digital SAT testing application (Bluebook) has a built-in Desmos graphing calculator that is available for the entire Math section. However, many students perform better with the physical calculator they’ve practiced with. Our guide to the digital SAT format has more information.
6. What happens if I bring a prohibited calculator?
The test proctor will not allow you to use it. You may be forced to take the Math section without a calculator, or in a worst-case scenario, you could be dismissed from the test and have your scores canceled. It is critical to ensure you only bring approved calculators for the SAT.
7. Are four-function calculators allowed?
Yes, they are allowed, but they are not recommended. A four-function calculator lacks the scientific and graphing capabilities that are very helpful for solving SAT Math problems efficiently. While it is technically an approved calculators for the sat, you would be at a disadvantage.
8. Can I share my calculator with another student?
No. Sharing calculators is strictly forbidden during the exam. Each student must have their own approved device. Read more on our SAT rules overview page.
