What is an SAT Approved Calculator?
An SAT approved calculator is any handheld, battery-operated calculator that meets the specific guidelines set by the College Board for use on the Math section of the SAT. The policy is designed to ensure fairness and prevent any student from having an unfair technological advantage. Not all calculators are allowed; devices with features like internet connectivity, QWERTY keyboards, or Computer Algebra Systems (CAS) are strictly prohibited. Understanding whether your device is an SAT approved calculator is critical before test day.
This policy applies to students taking the digital SAT, who can either use their own qualifying handheld device or the built-in Desmos graphing calculator provided in the Bluebook testing app. The main types of allowed calculators are graphing calculators, scientific calculators, and four-function calculators, although the latter is not recommended due to its limited functionality for complex problems.
Common Misconceptions
A frequent misconception is that any graphing calculator is acceptable. However, many advanced graphing calculators include a Computer Algebra System (CAS), which can perform symbolic algebra, and these are explicitly banned. Another incorrect belief is that the most expensive calculator is the best. In reality, familiarity and speed with a mid-range, compliant SAT approved calculator are far more valuable than a high-end, prohibited one. Finally, devices like smartphones, tablets, or laptops are never allowed as a substitute.
SAT Approved Calculator: Rules and Criteria
There is no mathematical “formula” to determine if a calculator is an SAT approved calculator. Instead, it’s a process of checking your device against a list of rules and prohibited features. The College Board’s policy is based on what a calculator *cannot* do.
The step-by-step process for checking your calculator is as follows:
- Check for a QWERTY Keyboard: Look at the keypad. If it resembles a computer keyboard, it’s prohibited.
- Verify it is Battery-Powered: The calculator must run on batteries. Devices that need to be plugged into an electrical outlet are not allowed.
- Check for Communication Technology: Any calculator with internet, Wi-Fi, Bluetooth, or cellular capabilities is banned.
- Identify Prohibited Peripherals: Calculators that use a stylus, make noise, or have a paper tape printer are not permitted.
- Check for a Computer Algebra System (CAS): This is a critical rule. A CAS can solve algebraic equations symbolically. Look for “CAS” in the model name (e.g., TI-Nspire CX II CAS) or check if it can factor expressions like (x^2-4) into (x-2)(x+2). If it has CAS, it is not an SAT approved calculator.

Practical Examples of SAT Calculator Checks
Example 1: The Compliant Student
A student has a TI-84 Plus CE. They use our calculator checker. The model name does not contain “CAS” and is on the widely approved list. They check the boxes for prohibited features, and none apply. The tool correctly identifies it as an SAT approved calculator. The student can confidently bring this device to the test, knowing it meets all College Board requirements.
- Input Model: TI-84 Plus CE
- Prohibited Features: None
- Result: Approved
- Interpretation: This is a standard and highly recommended SAT approved calculator.
Example 2: The Student with a Prohibited Device
Another student has a TI-89 Titanium. This is a powerful calculator, but they notice it has a CAS. When they enter the model, the checker flags it as “Prohibited” because models starting with “TI-89” are explicitly banned by the College Board. This warning prevents the student from bringing a non-compliant device and facing potential disqualification. This is not an SAT approved calculator.
- Input Model: TI-89 Titanium
- Prohibited Features: Computer Algebra System (CAS)
- Result: Prohibited
- Interpretation: This calculator is banned due to its CAS functionality, which offers an unfair advantage. The student must find an alternative. For more details, see our section on {related_keywords}.

Key Factors That Affect SAT Calculator Approval
Several key factors determine whether a device is a valid SAT approved calculator. Ignoring these can lead to issues on test day.
- Computer Algebra System (CAS): This is the most significant factor. CAS functionality is banned because it automates complex algebra, which is a skill the SAT is designed to test.
- QWERTY Keyboards: Any calculator with a computer-style keyboard is prohibited to prevent storing notes or communicating.
- Connectivity (Internet, Bluetooth): A core rule is that the calculator cannot communicate with any other device or the internet. This maintains the integrity of the exam.
- Power Source: The policy strictly requires battery-operated calculators. This prevents logistical issues with power cords and ensures all students use similar handheld technology.
- Stylus and Touchscreens: Devices requiring a stylus or pen are generally prohibited, as they often have advanced functionalities beyond that of a standard calculator.
- Physical Form Factor: The device must be a dedicated calculator. Laptops, tablets, smartwatches, and mobile phones are explicitly forbidden, even if they have a calculator app. You can learn more about test day readiness in our article about {related_keywords}.
