SAT Calculator Policy Checker

Instantly determine if your calculator model meets the official College Board guidelines for the SAT exam.

Is Your Calculator Allowed?

Answer the following questions about your calculator’s features to check its eligibility for the SAT.

What is the SAT Calculator Policy?

The SAT calculator policy outlines which calculators are permitted and prohibited during the math portion of the exam. The goal is to ensure fairness and prevent any student from having an unfair advantage. While you can bring your own calculator, it must adhere to a strict set of rules. The Digital SAT also includes an embedded Desmos graphing calculator, which all students can use.

Generally, most graphing calculators and all scientific and four-function calculators are allowed. However, devices with features that could compromise the test’s integrity are strictly forbidden. This includes any device that can connect to the internet, communicate with other devices, or has a computer-like keyboard.

Determining if Your Calculator is Allowed: The Core Logic

Our checker simplifies the official College Board rules into a series of questions. The policy isn’t based on a mathematical formula but on a checklist of prohibited features. A calculator is deemed unacceptable if it has one or more of these forbidden characteristics. The table below outlines these “variables.”

SAT Calculator Feature Checklist

Feature (Variable)	Meaning	Status if “Yes”	Typical Range of this Feature
QWERTY Keyboard	A keyboard layout like a computer.	Prohibited	Found on laptops, tablets, and some organizer-type calculators.
Wireless Capability	Any function that allows it to connect to the internet or other devices (Wi-Fi, Bluetooth).	Prohibited	Smartphones, smartwatches, tablets.
External Power	Requires an electrical outlet to work. Battery power is acceptable.	Prohibited	Printing calculators or very old models.
Stylus / Pen Input	Uses a stylus for input on the screen.	Prohibited	Some advanced models like the Casio ClassPad.
Noise / Printing	Makes sounds that are not disabled or has a paper tape printer.	Prohibited	Some older desktop calculators.
Computer Algebra System (CAS)	Can perform symbolic algebra (e.g., factor polynomials).	Prohibited	High-end models like TI-89, HP Prime, and TI-Nspire CAS versions.

Practical Examples

Example 1: A Texas Instruments TI-84 Plus

• Inputs: QWERTY (No), Wireless (No), Power Cord (No), Stylus (No), Noise (No), CAS (No).
• Result: Likely Allowed.
• Reasoning: The TI-84 Plus is a standard graphing calculator and one of the most common models used for the SAT. It has none of the features explicitly prohibited by the College Board.

Example 2: A Smartphone’s Calculator App

• Inputs: QWERTY (Yes, virtual), Wireless (Yes), Power Cord (No), Stylus (Sometimes), Noise (Can be muted), CAS (Sometimes).
• Result: Not Allowed.
• Reasoning: Smartphones are prohibited because they have wireless communication capabilities, which is a major violation of test security rules.

How to Use This SAT Calculator Policy Checker

Using this tool is straightforward:

1. Read each question carefully. Each question corresponds to a rule from the official College Board policy.
2. Select “Yes” or “No” based on your calculator’s features. If you are unsure about a feature, it’s best to check the manufacturer’s website or the official SAT calculator policy.
3. Click the “Check Eligibility” button.
4. The result will instantly appear, telling you if your calculator is “Likely Allowed” or “Not Allowed” and providing a brief explanation.

Key Factors That Affect Calculator Approval

• Test Security: The primary factor is preventing cheating. Any feature that allows for communication or storing large amounts of text is banned.
• Fairness: Rules are in place to ensure no student has an unfair advantage from a vastly superior machine. The ban on CAS calculators is a key part of this.
• Distraction: Features like noise and paper tape are prohibited to maintain a quiet and focused testing environment for all students.
• Hardware Type: Only handheld, battery-operated devices are permitted. This excludes laptops, tablets, and phones.
• Input Method: QWERTY keyboards and styluses are not allowed as they resemble computer-like functionality.
• Familiarity: Even with an approved calculator, your familiarity with it is crucial. It’s recommended to practice with the same calculator you’ll use on test day.

Frequently Asked Questions (FAQ)

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

Yes, all versions of the TI-84 Plus are allowed and are very popular for the SAT.

2. What if my calculator has programs on it?

The College Board requires that you remove any programs that have algebra functionality or stored documents.

3. Can I share my calculator with a friend?

No. Sharing calculators during the exam is strictly prohibited.

4. Do I have to bring my own calculator?

Yes, you must bring your own approved calculator. However, the digital SAT has a built-in Desmos calculator you can use as an alternative or in conjunction with your own.

5. Are all scientific calculators allowed?

Yes, the policy states that all scientific calculators are permitted.

6. What happens if I bring a prohibited calculator?

You will not be allowed to use it. In the worst-case scenario, if you are caught using a prohibited device during the exam, you could be dismissed and have your scores canceled.

7. Can I use the calculator on all sections of the SAT?

No, the calculator is only permitted on the Math section. You must put it away during the Reading and Writing section.

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

A CAS can manipulate mathematical expressions symbolically (e.g., factor ‘x^2 – 4’ into ‘(x-2)(x+2)’). They are banned to ensure students demonstrate their own algebra skills, not just the calculator’s.
