Instantly check the official College Board policy for the Digital SAT. Select the test section to see if a calculator is permitted and view the specific rules.

SAT Calculator Policy Overview

Summary of calculator rules for the Digital SAT.

Test Section	Calculator Use Permitted?	Key Rules & Information
Math Section	Yes	A calculator is available for the entire Math section. You can use the built-in Desmos graphing calculator or bring your own approved device.
Reading & Writing Section	No	Calculators are strictly prohibited during the Reading and Writing section. You must put your calculator away.

What is the SAT Calculator Policy?

The SAT calculator policy refers to the set of rules defined by the College Board that dictates when and how students can use a calculator during the exam. Understanding if you can use calculators on the SAT is crucial for test day success. For the Digital SAT, the policy is straightforward: calculators are an integral tool for the Math section but are forbidden during the Reading and Writing section. This policy ensures fairness and tests a range of mathematical skills—some that benefit from a calculator and others that rely on mental math and problem-solving.

Anyone taking the Digital SAT should be familiar with these rules. This includes knowing that you have two options for the Math section: use the powerful, built-in graphing calculator (powered by Desmos) provided within the testing application, or bring your own approved handheld calculator. A common misconception is that you *must* use the built-in tool; however, you are free to use your own familiar device, as long as it meets the College Board’s criteria.

SAT Calculator Rules Explained

The fundamental “formula” for determining if you can use calculators on the SAT depends entirely on the test section. There is no longer a “No-Calculator” subsection within the Math test as there was with the paper-based test. The rule is now binary based on the main subject.

Step-by-step Policy Breakdown:

1. Identify the Test Section: Are you in a Math module or a Reading & Writing module?
2. Math Section Rule: If you are in the Math section, the answer is YES. You have access to a calculator for every single question. You can either use the integrated Desmos calculator or your own approved handheld device.
3. Reading & Writing Section Rule: If you are in the Reading & Writing section, the answer is NO. Calculators must be put away and cannot be on your desk. Using one in this section is a violation of test rules.

Policy Components Table

Detailed breakdown of SAT calculator policy components.

Component	Meaning	Applies to	Typical Guideline
Built-in Calculator	The Desmos-powered graphing calculator within the testing software.	Math Section	Available for all students on all math questions.
Personal Calculator	A handheld, battery-operated calculator you bring to the test center.	Math Section	Must be an approved model (most graphing and scientific are okay).
Prohibited Calculators	Devices not allowed, such as those with CAS, QWERTY keyboards, or internet.	All Sections	Use leads to dismissal. Includes phones, smartwatches, etc.
Calculator Sharing	Giving your calculator to or borrowing one from another student.	All Sections	Strictly forbidden.

Practical Examples

Example 1: Student in the Math Section

• Scenario: Maria is on question 15 of the first Math module. The question involves solving a system of linear equations.
• Action: She has two choices. She can click the calculator icon on her screen to open the built-in Desmos graphing calculator, where she can graph both lines to find the intersection point. Alternatively, she can use her personal, approved TI-84 Plus calculator to use its matrix solver or graphing functions.
• Outcome: By using the calculator, she quickly and accurately finds the solution, saving time and reducing the chance of a manual calculation error. Her choice to use a calculator here is a correct application of the policy.

Example 2: Student in the Reading & Writing Section

• Scenario: David is working on a question in the Reading & Writing section. He has his personal calculator on his desk from the previous Math module.
• Action: A proctor sees the calculator on the desk. The proctor will instruct him to put it away immediately.
• Outcome: Even if he wasn’t using it, having a calculator out during a non-calculator section is a violation. It’s critical to store the device properly between sections. The question of can you use calculators on the SAT has a clear “no” for this part of the exam.

How to Use This Calculator Policy Checker

This tool simplifies the official rules about whether you can use calculators on the SAT into a quick and easy check.

1. Select the Section: Use the dropdown menu at the top of the page. Choose the part of the Digital SAT you’re curious about (“Math Section” or “Reading & Writing Section”).
2. View the Result: The tool will instantly update. A large “YES” in a green box means a calculator is allowed, while a “NO” in a red box means it is prohibited.
3. Read the Details: Below the main result, the tool provides key details, including what types of calculators are allowed (built-in vs. personal) and a list of prohibited actions.
4. Consult the Flowchart: The dynamic flowchart visually confirms the policy, highlighting the path from your selection to the correct outcome.

Key Factors That Affect Calculator Use

Several factors determine the policy around whether you can use calculators on the SAT. Being aware of them is essential for a smooth test day experience.

• 1. Test Section: This is the most important factor. As this tool shows, calculators are permitted only in the Math section.
• 2. Calculator Type (No CAS): The College Board has banned calculators with Computer Algebra Systems (CAS). A CAS can perform symbolic algebra, like factoring `x^2-4` into `(x-2)(x+2)`. You must ensure your calculator is a non-CAS model.
• 3. Prohibited Features: Devices with internet connectivity, QWERTY (typewriter-style) keyboards, paper tape, or that need a power cord are not allowed. This rule also bans using smartphones, tablets, or laptops as calculators.
• 4. The Digital SAT’s Built-in Tool: The presence of the Desmos calculator in the Bluebook testing app is a major factor. It provides a powerful, free, and universally available graphing calculator to all test-takers, leveling the playing field.
• 5. Battery and Condition: You are responsible for your own calculator. It must be battery-operated and in good working order. Test centers will not provide batteries or backup calculators.
• 6. No Sharing: The policy strictly prohibits sharing calculators. Bringing a backup calculator is a wise strategy, but you must keep it under your seat unless you get permission to swap.

Frequently Asked Questions (FAQ)

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

Yes, the TI-84 Plus, including the CE version, is one of the most popular and widely approved graphing calculators for the SAT. It does not have a prohibited CAS feature.

2. Is the built-in Desmos calculator good enough for the SAT?

Absolutely. The integrated Desmos calculator is a full-featured graphing calculator that is powerful enough for any question on the SAT. Many students find it more intuitive than handheld calculators for graphing functions.

3. Do I have to use the built-in calculator?

No, you are not required to use the built-in Desmos calculator. You can choose to use your own approved handheld calculator for the entire Math section if you are more comfortable with it.

4. What happens if I use a calculator on the Reading & Writing section?

Using a calculator during the Reading & Writing section is a prohibited action. You would likely be warned by the proctor, and in serious cases, you could be dismissed from the test and have your scores canceled.

5. Are scientific calculators allowed on the SAT?

Yes, all standard scientific calculators are allowed. This provides a good option if you don’t need graphing capabilities but want more functions than a basic four-function calculator.

6. What is a Computer Algebra System (CAS) and why is it banned?

A CAS is a feature that allows a calculator to manipulate algebraic expressions symbolically (e.g., factor, expand, or solve for variables). The College Board banned these calculators to ensure the test assesses the student’s mathematical skills, not the calculator’s power.

7. Can I bring a backup calculator?

Yes, you can bring a backup calculator. However, it must be stored under your desk. You need to get permission from the proctor before you can swap it with the one you are using.

8. Is the question of can you use calculators on the SAT different for the Digital SAT vs. the old paper test?

Yes. The old paper test had a Math section split into two parts: a “No-Calculator” section and a “Calculator” section. The new Digital SAT simplifies this: the entire Math section permits calculator use.
