What are SAT Approved Calculators?
SAT Approved Calculators are specific handheld devices that the College Board permits students to use during the Math section of the SAT exam. The purpose of the SAT calculator policy is to ensure fairness and prevent any student from having an unfair advantage through technology. While the digital SAT provides a built-in Desmos calculator, many students prefer using a physical, familiar device. Understanding which devices are SAT approved calculators helps you prepare effectively and avoid issues on test day.
This policy applies to everyone taking the SAT, whether you’re a high school student aiming for college admission or an adult learner. The core idea is that the test should measure your math skills, not your ability to operate a mini-computer. A common misconception is that all graphing calculators are fine, but certain features, especially Computer Algebra Systems (CAS), are strictly forbidden. Using one of the many SAT approved calculators you’ve practiced with is a key testing strategy.
SAT Calculator Policy Explained
The SAT calculator policy is not a simple list of models but a set of rules based on features. The primary rule is that calculators with a Computer Algebra System (CAS) are prohibited. Additionally, devices with features like wireless communication, QWERTY keyboards, or those that need an electrical outlet are not allowed. Below is a breakdown of the feature-based rules that determine which devices are considered SAT approved calculators.
| Feature / Rule | Meaning | SAT Policy Status | Typical Example |
|---|---|---|---|
| No Computer Algebra System (CAS) | Cannot symbolically solve equations (e.g., factor x²-1 into (x-1)(x+1)). | Strictly Prohibited | TI-Nspire CX II CAS, HP Prime |
| No QWERTY Keyboard | Must not have a typewriter-style lettered keyboard. | Strictly Prohibited | Any calculator with a full alphabet keyboard |
| No Wireless/Internet | Cannot connect to the internet, Bluetooth, or other networks. | Strictly Prohibited | Smartphones, smartwatches, tablets |
| Battery Operated Only | Must run on batteries; cannot be plugged into an outlet. | Required | Most handheld calculators |
| No Stylus / Pen-Input | Must not use a stylus for operation. | Strictly Prohibited | Some older PDA-style devices |
| Graphing Capability | Can plot equations on a coordinate plane. | Allowed (if non-CAS) | TI-84 Plus, Casio fx-9750GIII |
Practical Examples
Understanding the rules is easier with concrete examples. Here’s how the SAT calculator policy applies to some popular models, determining if they are SAT approved calculators.
Example 1: The Standard Graphing Calculator
- Calculator Model: Texas Instruments TI-84 Plus CE
- Inputs: No CAS, no QWERTY keyboard, no wireless.
- Result: Allowed. This is one of the most common SAT approved calculators. Its graphing capabilities are permitted, and it lacks any prohibited features.
- Interpretation: This calculator is a safe and powerful choice for the SAT. Students should practice with it to become efficient at graphing and calculations.
Example 2: The Banned High-End Calculator
- Calculator Model: Texas Instruments TI-Nspire CX II CAS
- Inputs: Contains a Computer Algebra System (CAS). The “CAS” in the name is a major red flag.
- Result: Not Allowed. Despite its powerful features, the CAS functionality violates the core SAT calculator policy.
- Interpretation: Even though the non-CAS version (TI-Nspire CX II) is allowed, this specific model is banned. This highlights the importance of checking the exact model name. Before you make a purchase, check out our guide to the best calculators for college to ensure it aligns with testing rules.
How to Use This SAT Approved Calculators Checker
This tool simplifies checking your device against the SAT calculator policy. Follow these steps:
- Enter Model: Type your calculator’s model name into the input field. Be as precise as possible.
- Check Eligibility: Click the “Check Eligibility” button to run the analysis.
- Review Results: The tool will provide a clear status: “Allowed,” “Not Allowed,” or “Check Features.” It will also list the reasons for the decision, helping you understand the specific rule that applies to your device. This makes it easy to confirm if you have one of the many SAT approved calculators.
- Decision-Making: If your calculator is not allowed, you will need to acquire a different one for test day. The built-in Desmos calculator on the digital SAT is always an option, but practicing with your own SAT math formulas on a physical, approved device is highly recommended.
Key Factors That Affect Calculator Eligibility
Several critical features can disqualify a calculator. Understanding these factors is essential for choosing from the list of SAT approved calculators and avoiding problems on test day.
- Computer Algebra System (CAS): This is the most common reason for a powerful calculator to be banned. A CAS can perform algebraic manipulations, which the College Board considers an unfair advantage.
- QWERTY Keyboard: Any calculator with a typewriter-style keyboard is prohibited. This is to prevent the storing of notes or other unauthorized assistance.
- Wireless Connectivity: Devices with Wi-Fi, Bluetooth, or any cellular connection are strictly forbidden. This rule prevents any form of communication during the test.
- Power Source: Calculators requiring an electrical outlet are not allowed. Your device must be battery-powered. Be sure to bring fresh batteries!
- Stylus or Pen-Based Input: Devices that use a stylus are not permitted, as they often resemble PDAs or other computer-like devices.
- Audible Output or Printing: Calculators that make noise or print to a paper tape cannot be used.

Frequently Asked Questions (FAQ)
1. Can I use a TI-84 Plus on the SAT?
Yes, the entire TI-84 Plus family (including the Plus, C Silver Edition, and CE) are SAT approved calculators. They are some of the most popular and recommended choices for the exam.
2. Is the TI-Nspire allowed on the SAT?
It depends. The standard TI-Nspire CX and CX II (non-CAS models) are allowed. However, the TI-Nspire CX CAS and CX II CAS models are strictly prohibited due to their Computer Algebra System. Always check for “CAS” in the model name.
3. What if I forget my calculator on test day?
For the digital SAT, you are in luck. A powerful graphing calculator (Desmos) is built directly into the testing application (Bluebook), so you will not be left without one. However, it’s always best to bring a physical calculator you are familiar with.
4. Are scientific calculators allowed on the SAT?
Yes, all standard scientific calculators are allowed. Models like the TI-30X series are perfectly acceptable SAT approved calculators, though they lack the graphing capabilities of more advanced models.
5. Can I share my calculator with a friend during the test?
No. Sharing calculators is strictly prohibited under the official SAT calculator policy. Each student must have their own approved device.
6. Do I need to clear my calculator’s memory?
Yes, the policy requires that you remove any stored programs or documents. While proctors may not inspect every calculator, it is your responsibility to comply with this rule.
7. Can I bring a backup calculator?
Yes, you can bring a backup calculator. During the test, it must be kept under your chair. You must get permission from the proctor before swapping calculators. This is a good strategy in case your primary one fails.
8. Why are CAS calculators banned?
CAS (Computer Algebra System) calculators are banned because they can solve algebraic equations symbolically, factor expressions, and perform other advanced manipulations that the SAT is designed to test. Allowing them would create an unfair advantage.
