Are You Allowed A Calculator On The Sat

Is Your Calculator Allowed on the SAT?

Find out instantly if you can bring your calculator on test day. The rules depend on the test section and the type of calculator you have.

Are You Allowed a Calculator on the SAT? The Official Policy

Navigating the rules for what you can and cannot bring to the SAT can be stressful, especially concerning calculators. The College Board has a specific SAT calculator policy to ensure fairness and prevent academic dishonesty. Understanding this policy is crucial for test day success. The answer to “are you allowed a calculator on the sat” depends on two key things: the test section and the calculator’s features.

For the paper-and-pencil SAT, the Math test is split into two parts: a “No-Calculator” section and a “Calculator” section. As the names imply, you cannot use a calculator on the former, but you can on the latter. For the newer Digital SAT, the policy is simpler: you can use an approved calculator on the entire Math section. The Digital SAT also includes a built-in Desmos-powered graphing calculator that you can use.

How the SAT Calculator Policy Checker Works

This interactive tool simplifies the official College Board rules. It acts as a decision-making calculator based on the established policies. The logic is as follows:

1. Test Section: First, it confirms you are asking about the correct section. Calculators are strictly forbidden during the Reading & Writing section. If you select the “Math Test – No-Calculator” section, the tool will immediately tell you a calculator is not allowed.
2. Calculator Type: If you select the “Math Test – Calculator” section, the tool then asks for your calculator’s type. It checks your selection against the list of prohibited features.
3. The Verdict: Based on your inputs, it delivers a clear result: Allowed, Not Allowed, or a warning for specific cases (like Computer Algebra System (CAS) models which were recently banned).

What Calculators Are Permitted on the SAT?

Generally, most graphing calculators and all scientific and four-function calculators are permitted. However, there are critical exceptions. The main takeaway from the SAT calculator rules is to avoid devices with features that can give an unfair advantage. For more details, explore our digital SAT guide.

Allowed vs. Prohibited Calculator Features

This table summarizes the key features that determine if your calculator is acceptable.

Summary of SAT Calculator Feature Policies

Feature	Status	Reasoning & Notes
Scientific & Four-Function	Allowed	All standard scientific and four-function calculators are acceptable.
Most Graphing Calculators	Allowed	Most models like the TI-84 Plus series are allowed and widely used.
Computer Algebra System (CAS)	Not Allowed	Calculators that can symbolically solve algebra (e.g., factor, expand) are banned. This includes the TI-Nspire CAS and HP Prime.
QWERTY Keyboard	Not Allowed	Any calculator with a typewriter-style keyboard (like the TI-92) is prohibited.
Wireless, Bluetooth, or Internet	Not Allowed	Devices that can communicate externally are strictly forbidden.
Phones, Tablets, Laptops	Not Allowed	You cannot use general-purpose computing devices as your calculator.
Requires Electrical Outlet	Not Allowed	Calculators must be battery-operated.

Practical Examples

Let’s see how the policy applies to common scenarios.

Example 1: Student with a TI-84 Plus

• Inputs: Section = “Math Test – Calculator”, Type = “Graphing Calculator (no CAS)”
• Units: This is a policy check, so it’s unitless.
• Result: ALLOWED. The TI-84 Plus is one of the most common and perfectly acceptable calculators for the SAT.

Example 2: Student with a TI-Nspire CX II CAS

• Inputs: Section = “Math Test – Calculator”, Type = “Graphing Calculator with CAS”
• Units: Unitless.
• Result: NOT ALLOWED. Because this calculator has a Computer Algebra System (CAS), it is prohibited from use on the SAT. Knowing the approved SAT calculators is vital.

How to Use This SAT Calculator Policy Checker

Using this tool is a simple, three-step process to determine if you are allowed a calculator on the SAT.

1. Select the Test Section: Choose the part of the SAT you’re asking about from the first dropdown. Remember, calculators are only a consideration for the Math section.
2. Specify Your Calculator Type: In the second dropdown, select the category that best describes your device. If you’re unsure, check your calculator for a “CAS” label or a QWERTY keyboard.
3. Check and Interpret the Result: Click “Check Now”. The result box will appear with a clear, color-coded answer explaining the policy as it applies to your situation. Use the “Reset” button to start over.

Key Factors That Affect Calculator Approval

Several factors determine if a calculator is permitted. The question “are you allowed a calculator on the sat” is more complex than a simple yes or no.

• 1. Computer Algebra System (CAS): This is a major disqualifier. CAS can solve algebraic equations symbolically, which the College Board deems an unfair advantage.
• 2. QWERTY Keyboard: Any calculator with a non-numeric, full keyboard is banned to prevent storing text.
• 3. Communication Capability: Devices with Wi-Fi, Bluetooth, or cellular access are prohibited.
• 4. Power Source: The calculator must be battery-powered. No plug-in devices are allowed.
• 5. Noise and Distractions: Devices that make noise, have a paper tape, or feature a very large/raised display may be prohibited or require special seating.
• 6. Test Format (Paper vs. Digital): While the list of approved physical calculators is the same, the Digital SAT uniquely offers a powerful built-in graphing calculator for all students. You can compare test formats in our ACT vs SAT comparison.

Frequently Asked Questions (FAQ)

1. Can I use a TI-84 on the SAT?

Yes, all versions of the Texas Instruments TI-84 (Plus, CE, etc.) are allowed on the SAT as they do not have a prohibited CAS. They are among the most recommended models.

2. Are scientific calculators allowed on the SAT?

Yes, all standard scientific calculators are allowed on the SAT.

3. What happens if I bring a banned calculator?

If you bring a prohibited calculator, the test proctor will not allow you to use it. You would have to take the math section without it, putting you at a significant disadvantage.

4. Do I have to use the built-in Desmos calculator on the Digital SAT?

No, you are not required to use it. You may bring your own approved handheld calculator in addition to having access to the on-screen one.

5. Are there any changes to the SAT calculator rules for 2026?

The major recent change was the banning of all CAS calculators. This policy is in effect for 2026. Always check the official College Board website for the latest updates before your test.

6. Can I share my calculator with a friend?

No. Sharing calculators is strictly forbidden during the exam. You must bring your own.

7. Do I need to clear my calculator’s memory?

Yes, proctors may ask you to clear your calculator’s memory of any stored programs or documents before the test begins to ensure no unfair information is stored.

8. Is a four-function calculator good enough for the SAT?

While technically allowed, a four-function calculator is not recommended. It lacks the functions needed for more complex problems, such as trigonometry or exponents, which can slow you down significantly.
