SAT Approved Calculator Checker
Instantly verify if your calculator is permitted for use on the SAT exam. This tool and guide reflect the latest College Board SAT calculator policy to help you prepare.
Check Your Calculator’s Status
What is an SAT Approved Calculator?
An SAT Approved Calculator is a handheld, battery-operated device that meets the specific policy requirements set by the College Board for use during the Math section of the SAT exam. While a calculator is not required for all questions, having a familiar and permissible tool is a significant advantage. The policy is designed to ensure fairness and prevent any student from having an unfair advantage through technology. Generally, most scientific calculators and non-CAS graphing calculators are acceptable. Common misconceptions include thinking any graphing calculator is fine, or that the most expensive model is the best. In reality, the rules are very specific, and familiarity with your own SAT Approved Calculator is more important than its price tag.
SAT Approved Calculator Rules: The “Formula” Explained
The “formula” for determining if a calculator is an SAT Approved Calculator isn’t a mathematical equation, but a set of rules based on device features. The College Board explicitly prohibits certain types of devices and features to maintain a level playing field. Any calculator that has features on the prohibited list will not be allowed in the test room. Understanding these rules is crucial for test day.
| Feature/Rule | Meaning | Allowed Status | Reasoning |
|---|---|---|---|
| Computer Algebra System (CAS) | Ability to manipulate symbolic equations (e.g., factor, solve for variables). | No | Provides an unfair advantage by solving algebraic problems automatically. |
| QWERTY Keyboard | A typewriter-style keyboard. | No | Resembles a communication device and is banned. |
| Wireless/Internet | Bluetooth, Wi-Fi, cellular, or any internet connectivity. | No | Prevents any possibility of external communication or data access. |
| Needs Electrical Outlet | Requires a power cord to operate. | No | All calculators must be battery-operated only. |
| Makes Noise or Prints | Calculators with sound or a paper tape printer. | No | Prevents disruption to other test-takers. |
| Stylus/Pen-Input | Devices like the Casio ClassPad. | No | These are considered computer-like devices and are prohibited. |
Practical Examples of Using the SAT Approved Calculator Checker
Example 1: A Permitted Calculator
- Input Model: TI-84 Plus
- Checker Result: Acceptable
- Interpretation: The TI-84 Plus is one of the most common and reliable choices. It is a powerful graphing calculator without CAS functionality, making it a perfect SAT Approved Calculator. It is fully compliant with all College Board rules.
Example 2: A Prohibited Calculator
- Input Model: TI-89 Titanium
- Checker Result: Not Acceptable
- Interpretation: The TI-89 Titanium has a Computer Algebra System (CAS), which is explicitly banned by the College Board. Even though it’s a powerful calculator, this feature disqualifies it for SAT use. Students with this calculator would need to get a non-CAS model like the TI-Nspire CX or TI-84 Plus.
How to Use This SAT Approved Calculator Checker
Using this tool is straightforward and designed to give you a quick, clear answer.
- Enter the Model: Type the full model name of your calculator into the input field above. For example, “Casio fx-9750GII”.
- Review the Status: As you type, the tool will instantly show a result: “Acceptable”, “Not Acceptable”, or “Check Details”.
- Check the Details: The checklist below the main result breaks down the reasoning, showing you how your calculator fares against key rules like CAS, QWERTY, and power source. This helps you understand *why* your device is or isn’t an SAT Approved Calculator.
- Decision-Making: If your calculator is “Not Acceptable,” you know you need to find an alternative for test day. The table below provides a list of generally accepted models. Remember, you can always use the built-in Desmos calculator provided in the Bluebook testing application.
Key Factors That Affect SAT Calculator Acceptability
Several key factors determine whether a device qualifies as an SAT Approved Calculator. It’s not just about the brand; it’s about the functionality.
- Computer Algebra System (CAS): This is the most significant factor. CAS calculators can perform symbolic algebra, which gives a distinct advantage. As a result, they are banned. You must ensure your calculator is a non-CAS model.
- QWERTY Keyboard: Any device with a typewriter-style keyboard is prohibited as it resembles a communication or text-storage device.
- Connectivity: Any form of wireless communication, including Bluetooth, infrared, or Wi-Fi, is strictly forbidden to prevent cheating. Your device must be completely offline.
- Power Source: The calculator must be battery-powered. Devices that need to be plugged into an electrical outlet are not allowed in the testing center.
- Physical and Peripheral Prohibitions: Calculators that make noise, have a paper tape, or use a stylus are not permitted. This ensures a quiet and fair testing environment.
- Digital Platform Availability: For the digital SAT, a powerful Desmos graphing calculator is built into the testing software (Bluebook). This means even if you don’t have a physical SAT Approved Calculator, you have a very capable tool available.
| Brand | Generally ACCEPTABLE Models (Non-CAS) | Generally UNACCEPTABLE Models |
|---|---|---|
| Texas Instruments | TI-83 Plus, TI-84 Plus series, TI-Nspire CX (non-CAS). | TI-89, TI-92, TI-Nspire CX CAS series. |
| Casio | fx-9750GII, fx-9860GII, FX-CG50. | ClassPad series, Algebra fx 2.0, models with CFX-9970G. |
| HP | HP 39gs, HP 50g (must remove CAS programs). | HP Prime, HP 48GII. |
Frequently Asked Questions (FAQ)
Yes, the TI-84 Plus, including the CE version, is one of the most widely used and recommended SAT Approved Calculator models. It does not have CAS functionality.
It depends on the model. The TI-Nspire CX (non-CAS) is allowed, but the TI-Nspire CX CAS and CX II CAS are prohibited. You must check that “CAS” is not in the model name.
If you bring a prohibited calculator, the test proctor will not allow you to use it. You will have to take the math section without it or rely solely on the built-in Desmos calculator.
Yes, all scientific calculators are allowed as long as they do not have any of the prohibited features like CAS or wireless communication.
The College Board requires that you remove any stored programs that have algebra functionality or any stored documents from your calculator before the test.
No, sharing calculators with other test-takers is strictly prohibited. You must bring your own device.
You are responsible for ensuring your calculator works on test day, including having fresh batteries. The test center will not provide replacements. You can, however, use the embedded Desmos calculator in the testing application.
While allowed, a four-function calculator is not recommended. It lacks the advanced functions (graphing, trigonometry) needed to solve many problems efficiently, putting you at a disadvantage.
