What Are SAT Acceptable Calculators?

SAT acceptable calculators are handheld, battery-operated devices approved by the College Board for use on the Math with Calculator section of the SAT. The policy is designed to ensure fairness and prevent any student from having an unfair advantage. While most graphing calculators and all scientific calculators are allowed, there are critical restrictions on features like internet connectivity, QWERTY keyboards, and, importantly, Computer Algebra Systems (CAS). Knowing if your device is one of the many sat acceptable calculators is crucial before test day.

SAT Calculator Policy and Rules

The College Board has a detailed policy that outlines which features are permitted and which are strictly forbidden. The primary rule is that the calculator cannot offer an unfair advantage. This means no devices that can communicate with other devices, access the internet, or perform symbolic algebraic manipulation.

Key Prohibited Features

To maintain a fair testing environment, the following types of devices and features are strictly prohibited:

• Laptops, tablets, smartwatches, or any wearable technology
• Calculators with a QWERTY (typewriter-style) keyboard
• Devices that can access the internet, have Bluetooth, or any wireless capability
• Calculators that have a pen-input, stylus, or touch-screen input (with some specific exceptions)
• Calculators that make noise or use an electrical outlet
• Models with a built-in Computer Algebra System (CAS). This is a significant rule, as CAS can solve algebraic equations symbolically.

For more details, consider reviewing a SAT prep course to understand all test-day rules.

Practical Examples of Calculator Status

Let’s look at how different models are classified under the sat acceptable calculators policy.

Example 1: Clearly Approved

• Input: TI-84 Plus
• Result: APPROVED. This is one of the most common and widely accepted graphing calculators for the SAT.

Example 2: Clearly Prohibited

• Input: TI-89 Titanium
• Result: PROHIBITED. This calculator has a built-in Computer Algebra System (CAS), which is explicitly banned by the College Board.

Example 3: Non-CAS Model is OK

• Input: TI-Nspire CX
• Result: APPROVED. This model is fine.
• Input: TI-Nspire CX II CAS
• Result: PROHIBITED. The “CAS” designation makes this model unacceptable for the exam.

How to Use This SAT Acceptable Calculators Checker

Using this tool is simple. Follow these steps to determine your calculator’s status:

1. Find the Model Name: Look at the front of your calculator. The model is usually printed at the top (e.g., “TI-84 Plus CE”, “Casio fx-9750GII”).
2. Enter the Model: Type the model name into the input field above. You don’t need to be exact with capitalization or dashes.
3. Check the Status: Click the “Check Status” button.
4. Interpret the Result: The tool will display one of three results: APPROVED, PROHIBITED, or CHECK MANUALLY. If it’s prohibited, the tool will state why (e.g., has CAS, QWERTY keyboard).

Understanding these results is a key part of your test preparation, much like using a college admissions calculator is for planning your applications.

Key Factors That Affect SAT Calculator Approval

Several factors determine if a calculator is approved. Here are the six most important ones to be aware of:

1. Computer Algebra System (CAS): This is the biggest disqualifier. CAS can manipulate variables and solve equations symbolically, which is a prohibited advantage.
2. QWERTY Keyboard: Any calculator with a typewriter-style keyboard is banned.
3. Connectivity: No internet, Bluetooth, cellular, or any other wireless communication is allowed.
4. Power Source: Calculators must be battery-powered. Devices that need to be plugged into an outlet are not permitted.
5. Stylus or Pen-Input: Most devices requiring a stylus are not allowed.
6. Noise/Printing: Calculators that make noise or print to a paper tape are forbidden.

A good ACT vs SAT guide will often highlight the differences in calculator policies between the two tests.

SAT Calculator Models: Approved vs. Prohibited

Here is a summary table of common calculator series and their general status. Always check your specific model, as variations exist.

This table provides a general guide. Status can change and specific models within a series may differ.

Brand & Series	General Status	Reasoning / Notes
Texas Instruments TI-83, TI-84	Approved	Standard graphing calculators without CAS. The TI-84 is a highly recommended model.
Texas Instruments TI-89, TI-92	Prohibited	These models all contain a Computer Algebra System (CAS).
Texas Instruments TI-Nspire (Non-CAS)	Approved	Models like the TI-Nspire CX and TI-Nspire CX II are allowed.
Texas Instruments TI-Nspire (CAS)	Prohibited	Any TI-Nspire model with “CAS” in its name is banned.
Casio fx-9750, fx-9860 series	Approved	These are popular and compliant graphing calculators.
Casio ClassPad Series	Prohibited	These have a large touch screen, stylus, and CAS functionality.
HP Prime	Prohibited	This model includes a CAS.
All Scientific Calculators	Approved	All standard scientific calculators are permitted.

Frequently Asked Questions (FAQ)

What happens if I bring a prohibited calculator?

The test proctor will not allow you to use it. You will have to take the math section without a calculator, putting you at a significant disadvantage. They will not provide a replacement. For help with math concepts, see our guide on SAT math topics.

Can I use a TI-Nspire CX II CAS?

No. Any calculator with “CAS” in its name is explicitly prohibited by the College Board’s policy. The non-CAS version, the TI-Nspire CX II, is allowed.

Are all scientific calculators allowed on the SAT?

Yes, all scientific calculators are acceptable for the SAT. They do not have the advanced graphing or CAS features that are restricted.

Do I have to clear my calculator’s memory?

While the ACT has rules about this, the College Board does not require you to clear your calculator’s memory for the SAT. However, you cannot use stored programs that solve problems for you.

Can I use my phone as a calculator?

Absolutely not. Mobile phones, smartwatches, and any similar electronic devices are strictly banned during the entire test.

Is the calculator on the digital SAT any good?

The digital SAT includes a built-in Desmos graphing calculator, which is very powerful. It’s recommended to practice with it before the test, but you are still allowed to bring your own handheld sat acceptable calculators. Learn more about the test format in our digital SAT overview.

What if my calculator model isn’t on any list?

If your calculator is not explicitly listed as prohibited and does not have any banned features (QWERTY keyboard, CAS, internet), it is likely allowed. This tool includes a comprehensive list, but the final authority is the feature set of the device.

Can I bring a backup calculator?

Yes, you can bring a backup calculator. It must also be an approved model. You have to keep it under your desk and must get permission from the proctor before swapping it.
