SAT Calculator Allowance Checker

An essential tool to determine if you are allowed to use a calculator during SAT tests based on the official 2025-2026 College Board policy.

Check Your Calculator’s Status

What is the SAT Calculator Policy?

The SAT calculator policy outlines the rules regarding which calculators are permitted for use during the exam. The College Board, which administers the SAT, has specific guidelines to ensure fairness and test security. Generally, most graphing calculators and all scientific calculators are acceptable. However, devices with prohibited features like a Computer Algebra System (CAS), QWERTY keyboard, internet access, or stylus are not allowed. For the Digital SAT, students can use an approved handheld calculator or the powerful Desmos graphing calculator built directly into the testing application.

The SAT Calculator Allowance Formula (Rule-Based Logic)

This checker doesn’t use a mathematical formula but a logical one based on the College Board’s rules. The primary determination is whether a calculator has features that are explicitly banned.

The logic follows these steps:

1. Is the section correct? Calculators are only permitted on the Math section. They are forbidden on the Reading and Writing section.
2. Does the model have a prohibited name? The tool checks for keywords that indicate a banned model (e.g., “CAS”, “TI-89”, “HP Prime”).
3. Does the model have prohibited features? It checks for terms indicating banned functionality like “QWERTY”, “phone”, “stylus”, or “wireless”.

Key Variables in Determining Calculator Allowance

Variable	Meaning	Unit/Type	Typical Values
Test Section	The part of the SAT being taken.	Categorical	Math, Reading, Writing
CAS Functionality	Computer Algebra System, which can solve algebra symbolically.	Boolean (Yes/No)	Prohibited. Models with “CAS” in the name are banned.
QWERTY Keyboard	A computer-style keyboard.	Boolean (Yes/No)	Prohibited.
Connectivity	Features like Wi-Fi, Bluetooth, or cellular access.	Boolean (Yes/No)	Prohibited.

Practical Examples

Example 1: A Permitted Calculator

• Input (Section): Math (Calculator Section)
• Input (Model): TI-84 Plus CE
• Result: ALLOWED
• Reasoning: The TI-84 Plus CE is a standard graphing calculator without CAS functionality and is widely accepted for the SAT.

Example 2: A Prohibited Calculator

• Input (Section): Math (Calculator Section)
• Input (Model): TI-Nspire CX II CAS
• Result: NOT ALLOWED
• Reasoning: The “CAS” in the model name indicates it has a Computer Algebra System, which is explicitly prohibited by the College Board starting in 2025.

How to Use This “Are You Allowed to Use a Calculator During SAT Tests” Checker

Using this tool is straightforward. Follow these steps to determine if your calculator is SAT-approved:

1. Select the Test Section: Choose the part of the SAT you are checking for from the first dropdown menu. Remember, calculators are never allowed on the Reading and Writing section.
2. Enter Your Calculator Model: In the text box, carefully type the model name and number of your calculator. For example, “TI-83 Plus” or “Casio fx-9750GII”.
3. Check Allowance: Click the “Check Allowance” button.
4. Interpret the Results: The tool will display a clear “ALLOWED” or “NOT ALLOWED” message, along with a brief explanation based on the official SAT calculator policy. For more details on the policy, you might want to read about the best SAT approved calculators.

Key Factors That Affect SAT Calculator Allowance

• Computer Algebra System (CAS): This is the most significant factor. Calculators with CAS can perform symbolic algebra, which is considered an unfair advantage. As of recent policy updates, all CAS calculators are banned.
• QWERTY Keyboards: Any calculator with a typewriter-style keyboard is prohibited.
• Wireless Communication: Calculators with Wi-Fi, Bluetooth, or any other form of wireless communication are not allowed to prevent cheating.
• Power Cords: Calculators must be battery-operated. Models that require a power cord are not permitted in the testing room.
• Noise and Printing: Devices that make noise or have a paper tape printer are banned.
• Stylus/Pen-Input: Calculators that use a stylus for operation are generally prohibited (e.g., Casio ClassPad).

Frequently Asked Questions (FAQ)

1. Can I use a calculator on the whole SAT?

No. You are only allowed to use a calculator on the Math section. It must be put away during the Reading and Writing section.

2. What if my calculator is not on the approved list?

The College Board no longer maintains a specific list of approved models. Instead, they provide a list of prohibited features and models. If your calculator does not have any prohibited features (like CAS), it is likely allowed. This tool helps you make that determination.

3. Are all scientific calculators allowed on the SAT?

Yes, all standard scientific calculators are permitted. They are a good choice if you are familiar with them.

4. What is a CAS calculator?

A CAS (Computer Algebra System) calculator can manipulate algebraic expressions symbolically. For example, it can solve an equation like ‘x + 2y = 4’ for ‘x’ to give ‘x = 4 – 2y’. Non-CAS calculators can only return a numerical answer. You can learn more about SAT CAS policies online.

5. Do I have to bring my own calculator?

While you should bring a calculator you are familiar with, the digital SAT includes an embedded Desmos graphing calculator that you can use. Test centers will not provide calculators.

6. Can I share my calculator with a friend?

No. Sharing calculators during the exam is strictly prohibited and can lead to score cancellation.

7. Is the TI-89 allowed on the SAT?

No. The TI-89 and TI-89 Titanium models are prohibited because they contain a Computer Algebra System (CAS).

8. What about the TI-Nspire?

It depends on the model. The standard TI-Nspire CX and CX II are allowed. However, the TI-Nspire CX CAS and CX II CAS models are banned. Check the name carefully!
