Can I Use My Calculator on the SAT?

SAT Calculator Eligibility Checker

Answer the following questions about your calculator to see if you can use it on the SAT. This checker reflects the latest College Board policies.

Does it have a QWERTY (computer-style) keyboard?
No

Is it part of a phone, tablet, laptop, or smartwatch?
No

Does it have wireless, Bluetooth, or internet capability?
No

Does it need to be plugged into an electrical outlet to work?
No

Does it have a Computer Algebra System (CAS)?
No

CAS calculators can solve equations symbolically (e.g., factor x^2-1). Many models with “CAS” in their name are prohibited.

Does it make noise, print paper tape, or use a stylus/pen?
No

Calculators that make noise, have paper tape, or use a stylus are not allowed.

What is the SAT Calculator Policy?

The SAT calculator policy outlines the rules for which types of calculators students can and cannot use during the math portion of the SAT exam. The purpose of this policy is to ensure fairness and prevent any student from having an unfair advantage due to superior calculator technology. While most scientific and graphing calculators are permitted, there are strict prohibitions against devices with features that could compromise test security, such as internet access or computer-style keyboards. Understanding if you can i use my calculator on the sat is a critical part of test preparation.

For the digital SAT, an on-screen graphing calculator (Desmos) is built into the testing application, Bluebook. However, students are still permitted to bring their own approved handheld calculator if they prefer. You cannot share a calculator with another student during the exam.

SAT Calculator Policy Explained: The Rules

Determining if you can i use my calculator on the sat is not based on a mathematical formula, but on a clear set of rules from the College Board. The logic is simple: if your calculator has any prohibited features, it is not allowed. All four-function, scientific, and most non-CAS graphing calculators are acceptable.

Prohibited Feature Checklist
Prohibited Feature	Explanation	Why it’s banned
Computer Algebra System (CAS)	Performs symbolic algebra (e.g., factoring, solving for variables).	Solves problems without requiring the student’s own algebraic skill.
QWERTY Keyboard	A typewriter-style keyboard.	Could be used to store notes or for communication.
Wireless/Internet Access	Any Bluetooth, Wi-Fi, or cellular capability.	Prevents accessing outside information during the test.
External Power	Requires an electrical outlet to function.	Testing centers do not provide power outlets for calculators.
Noise or Paper Tape	Calculators that make sounds or print results.	Could distract other test-takers.
Part of a Smart Device	Is a function of a phone, tablet, or computer.	These devices have broad capabilities that are not allowed.

Practical Examples: Allowed vs. Prohibited

Let’s look at two real-world examples to clarify if you can i use my calculator on the sat.

Example 1: The Texas Instruments TI-84 Plus

The TI-84 Plus is one of the most common graphing calculators used by students. It is fully permitted on the SAT.

Features Check: No QWERTY keyboard, no CAS, no wireless, battery-powered.
Result: ALLOWED. It meets all the criteria set by the College Board.

Example 2: The Texas Instruments TI-Nspire CX II-T CAS

This is a powerful calculator, but its advanced features make it prohibited.

Features Check: Contains a Computer Algebra System (CAS) as indicated by the “CAS” in its name.
Result: NOT ALLOWED. The presence of a CAS feature is an explicit violation of the SAT calculator policy.

How to Use This SAT Calculator Checker

This tool simplifies the process of checking your calculator’s eligibility. Follow these steps to determine if you can i use my calculator on the sat:

Review Your Calculator: Look at your calculator and identify its features. Look for labels like “CAS,” a full QWERTY keyboard, or symbols for Wi-Fi/Bluetooth.
Answer the Questions: For each question in the checker above, select ‘Yes’ if your calculator has the prohibited feature by un-checking the box.
View the Result: The tool will instantly provide a result: “ALLOWED” or “NOT ALLOWED”.
Check the Reasons: If your calculator is not allowed, the “Key Reasons for Decision” section will explain exactly which rule it violates.
Reset if Needed: Click the “Reset” button to clear your selections and check another calculator.

Key Factors That Affect SAT Calculator Eligibility

Several key factors determine whether you can i use my calculator on the sat. The College Board’s primary concern is maintaining a fair and secure testing environment.

Computer Algebra System (CAS): This is a major disqualifier. CAS can perform symbolic manipulations, which the SAT wants students to do by hand. As of recent policy changes, CAS calculators are explicitly banned.
Communication Features: Any form of wireless communication (Wi-Fi, Bluetooth) is strictly forbidden to prevent access to external information.
Keyboard Style: Calculators with typewriter-style (QWERTY) keyboards are prohibited as they could be used to store text.
Power Source: Your calculator must be battery-operated. Devices that need an electrical outlet are not allowed.
Output Methods: Any calculator that makes noise or prints to a paper tape is banned to avoid distracting others.
Associated Devices: You cannot use the calculator function on a smartphone, tablet, or laptop. The device must be a standalone calculator.

Frequently Asked Questions (FAQ)

1. What happens if I bring a prohibited calculator to the test?: The test proctor will not allow you to use it. You will have to take the math section without a calculator or use the built-in Desmos calculator on the digital SAT.
2. Are all graphing calculators allowed on the SAT?: No. Most are, but any graphing calculator with a prohibited feature like CAS or a QWERTY keyboard is not allowed.
3. Can I use a TI-84 Plus on the SAT?: Yes, all versions of the TI-84 Plus (including Plus CE) are explicitly allowed and are a popular choice for test-takers.
4. Is the TI-Nspire CX II (non-CAS version) allowed?: Yes. The non-CAS version of the TI-Nspire CX II is permitted. Only the models with “CAS” in the name are banned.
5. Do I need to clear my calculator’s memory?: The College Board requires that you remove any stored programs or documents from your calculator before the test.
6. Can I use my phone’s calculator if my main one breaks?: No. Phones and other smart devices are strictly prohibited from use during the test. It’s recommended to bring a backup calculator if you are concerned about malfunction.
7. Is a scientific calculator good enough for the SAT?: Yes, all scientific calculators are allowed and can handle most of the calculations on the SAT. However, a graphing calculator can solve some problems more quickly.
8. For the digital SAT, do I need to bring a calculator?: It is not required, as a powerful Desmos graphing calculator is built into the test software. However, you are still allowed to bring your own approved calculator if you are more comfortable with it.
