SAT Calculator Policy Checker
You are only permitted to use a calculator on the designated Math section.
According to official SAT policy, devices with these features are strictly prohibited.
What is the SAT Calculator Policy?
The SAT calculator policy defines the rules for using a calculator during the exam. While a calculator is not required to solve any question, it can be a valuable tool on the Math with Calculator section. The core of the policy is to ensure fairness and prevent any student from having an unfair advantage. Therefore, a common question students have is, “can i use a calculator on the sat?” The answer is yes, but only on the designated section and only with an approved device.
You are responsible for bringing your own approved calculator. Test centers will not provide them, and sharing calculators is strictly forbidden. The policy distinguishes between approved calculators (most scientific and graphing calculators) and prohibited ones, such as those with computer algebra systems (CAS), internet access, or QWERTY keyboards. Understanding if you can use a calculator on the SAT involves checking your device against the official guidelines.
SAT Calculator Rules Explained
To clarify whether you can use a calculator on the SAT, the College Board outlines specific features that are allowed and disallowed. The main distinction is between standard calculators and devices that can perform advanced symbolic manipulation or communicate externally. The following table breaks down the key rules.
| Feature / Rule | Status & Explanation |
|---|---|
| Test Section | Permitted on “Math with Calculator” section ONLY. Prohibited on Reading, Writing, and the “Math – No Calculator” section. |
| Calculator Types | Most graphing, scientific, and four-function calculators are allowed. The built-in Desmos calculator is also available on the digital SAT. |
| Computer Algebra System (CAS) | PROHIBITED. Calculators that can symbolically solve equations, factor, or expand expressions (e.g., TI-Nspire CAS, HP Prime) are not allowed. |
| QWERTY Keyboards | PROHIBITED. Any device with a computer-style keyboard is not allowed. |
| Connectivity | PROHIBITED. Devices with internet, cellular, Bluetooth, or infrared communication capabilities are not allowed. |
| Power Source | Must be battery-operated. Calculators that require an electrical outlet are prohibited. |
| Other Prohibited Devices | Laptops, mobile phones, smartphones, tablets, and smartwatches are never allowed as calculators. |
Practical Examples of Allowed and Prohibited Calculators
Example 1: Approved Calculator (TI-84 Plus)
The Texas Instruments TI-84 Plus is one of the most common and widely approved calculators for the SAT. It is a graphing calculator without a CAS, it’s battery-operated, and it has no prohibited features like a QWERTY keyboard or wireless capabilities. When a student asks, “can i use a calculator on the sat,” the TI-84 Plus is a textbook example of a “yes.” It’s perfect for graphing functions, analyzing statistical data, and performing complex calculations allowed on the exam.
Example 2: Prohibited Calculator (TI-Nspire CX II CAS)
The Texas Instruments TI-Nspire CX II CAS is a powerful calculator, but it is **not allowed** on the SAT. The “CAS” in its name stands for Computer Algebra System, which is the primary disqualifying feature. This system can solve algebraic equations symbolically, giving it capabilities that the College Board deems an unfair advantage. Despite its non-CAS counterpart (the TI-Nspire CX II) being allowed, the CAS version is explicitly prohibited. This highlights the importance of checking the exact model number.

How to Use This SAT Calculator Policy Checker
This tool is designed to quickly answer the question, “can i use a calculator on the sat?” for your specific device. Follow these simple steps:
- Select the Test Section: Choose the part of the SAT you’re asking about. Remember, calculators are only allowed on the Math with Calculator section.
- Identify Prohibited Features: Look at your calculator and check the box for any feature it has from the list. Be honest and thorough—even one prohibited feature will disqualify your device.
- Review the Result: The tool will instantly display “Allowed” or “Not Allowed” based on your inputs.
- A green “Allowed” means your device appears to comply with the rules for the selected test section.
- A red “Not Allowed” means your device is prohibited, and the reasons will be listed below.
- Use the Details: The intermediate results explain exactly why a calculator is not allowed, helping you understand the specific rule you’ve violated.
Key Factors That Affect Calculator Approval
Several key factors determine if a calculator is approved for the SAT. Understanding these will help you make the right choice and avoid issues on test day.
- Computer Algebra System (CAS): This is the most critical factor. A CAS can perform symbolic algebra, which is forbidden. Models with “CAS” in their name are an immediate red flag.
- Keyboard Style: A standard numeric keypad is fine, but a QWERTY keyboard is not. This rule prevents devices that are more like computers.
- Communication Technology: Any form of wireless communication (Wi-Fi, Bluetooth) or a physical data port for connecting to other devices can be a disqualifier.
- Power Source: The device must be portable and battery-powered. You cannot plug it into a wall. This is a simple but strict rule.
- Ancillary Functions: Features like cameras, audio recorders, or printers are strictly forbidden. A calculator should only be a calculator.
- Physical Size and Display: Calculators with very large digits (over one inch) or a raised display might lead to special seating arrangements to prevent others from seeing your screen. For a full checklist, see our guide on what to bring to the SAT.
Frequently Asked Questions (FAQ)
1. Can I use a calculator on the entire SAT?
No. Calculators are only permitted on the “Math with Calculator” section. They are strictly forbidden during the Reading, Writing, and “Math – No Calculator” sections.
2. What happens if I bring a prohibited calculator?
You will not be allowed to use it. The test proctor will likely ask you to put it away, and you will have to take the math section without a calculator. It is your responsibility to bring an approved device.
3. Is the TI-89 allowed on the SAT?
No. The TI-89 and TI-92 series are prohibited because they contain a built-in Computer Algebra System (CAS).
4. Are scientific calculators allowed on the SAT?
Yes, all standard scientific calculators are allowed. They are often a good choice as they handle all the necessary functions without the risk of being a prohibited model. Our SAT math section tips can help you decide what functions are most useful.
5. Do I have to clear my calculator’s memory?
Yes, you must remove any stored programs or documents. Test centers may inspect your calculator, and having stored information could lead to dismissal.
6. Can I use my phone as a calculator?
Absolutely not. Phones, tablets, and any other general-purpose electronic devices are strictly prohibited from being used as a calculator.
7. Is a four-function calculator good enough for the SAT?
While technically allowed, a four-function calculator is not recommended. It lacks functions for trigonometry, exponents, and logarithms, which can be very helpful for solving problems more quickly.
8. Where can I find the official list of banned calculators?
The College Board website maintains the most current SAT calculator policy, including examples of prohibited models. It’s the best source to consult before test day. Exploring digital SAT practice tests can also help you get used to the built-in Desmos tool.
