What is the SAT Calculator Policy?
The SAT Calculator Policy is a set of rules established by the College Board to ensure fairness and prevent academic dishonesty during the SAT exam. This policy dictates which calculators are permitted for use on the Math with Calculator section of the test. While students can use the built-in Desmos graphing calculator provided in the Bluebook testing app, many prefer to bring their own familiar handheld device. The core idea is to allow tools that aid in calculation without giving some students an unfair advantage through advanced symbolic manipulation or communication features. Understanding this policy is a key part of successful test preparation.
Generally, most graphing calculators and all scientific calculators are allowed. However, the main restriction is that calculators with a Computer Algebra System (CAS) are prohibited. Additionally, any device that can connect to the internet, has a QWERTY keyboard, or functions as a communication device (like a phone or tablet) is strictly forbidden.
The SAT Calculator “Formula”: How Eligibility is Determined
The “formula” for the SAT Calculator Policy is not a mathematical equation, but a decision-making process based on a device’s features. A calculator’s eligibility is determined by checking it against a list of prohibited attributes. The primary disqualifying feature is the presence of a Computer Algebra System (CAS). A CAS can manipulate algebraic expressions symbolically, for example, by factoring `x^2-1` into `(x-1)(x+1)`, which is considered an unfair advantage.
| Variable (Feature) | Meaning | Status | Typical Example |
|---|---|---|---|
| CAS Functionality | Ability to perform symbolic algebra (factor, solve for variables). | Prohibited | TI-Nspire CX II CAS, HP Prime |
| QWERTY Keyboard | A computer-style keyboard for typing text. | Prohibited | Old models with text input |
| Wireless Communication | Wi-Fi, Bluetooth, or any cellular connectivity. | Prohibited | Smartphones, tablets |
| External Power Source | Device requires a power cord to operate. | Prohibited | Laptops |
| Stylus or Pen Input | Touchscreen that uses a stylus. | Prohibited | Casio ClassPad series |
| Standard Graphing | Ability to graph equations and find numerical solutions. | Allowed | TI-84 Plus, Casio fx-9750GII |
Practical Examples (Real-World Use Cases)
Example 1: The Compliant Student (TI-84 Plus)
- Calculator Model: Texas Instruments TI-84 Plus
- Analysis: This model is on the College Board’s approved list. It does not have a CAS, a QWERTY keyboard, or any wireless capabilities. It is battery-operated.
- Result: ALLOWED. The student can confidently bring this calculator to the test.
Example 2: The Prohibited Calculator (TI-Nspire CX CAS)
- Calculator Model: Texas Instruments TI-Nspire CX CAS
- Analysis: The “CAS” in the model name explicitly indicates it has a Computer Algebra System. While there is a non-CAS version of the TI-Nspire CX that *is* allowed, this specific model is prohibited.
- Result: NOT ALLOWED. The student must find an alternative, non-CAS calculator for the exam.
How to Use This SAT Calculator Policy Checker
Using this tool is a simple way to verify your device against the official SAT Calculator Policy. Follow these steps:
- Enter Model Name: Type the full model name of your calculator into the input field. For instance, “TI-84 Plus CE”.
- Identify Prohibited Features: Look at your calculator. Does it have a QWERTY keyboard, a stylus, or wireless capabilities? Check the corresponding boxes.
- Click “Check My Calculator”: The tool will instantly analyze your inputs based on the known rules.
- Review the Results: The primary result will give you a clear “ALLOWED,” “NOT ALLOWED,” or “UNCERTAIN” status. The details below explain exactly *why* that decision was reached, referencing the specific rules from the policy.

Key Factors That Affect SAT Calculator Eligibility
- Computer Algebra System (CAS): This is the most critical factor. A calculator with CAS is automatically banned. You can often tell if a calculator has CAS if it can solve equations with variables or if “CAS” is in the model name.
- QWERTY Keyboard: Any calculator with a computer-style keyboard is not allowed.
- Connectivity: Any form of wireless communication (internet, Bluetooth) is forbidden to prevent cheating.
- Power Source: Calculators must be battery-powered. Devices that need to be plugged in are not permitted.
- Stylus/Pen Input: Devices that use a stylus for input are generally prohibited.
- Physical Size and Noise: Exceptionally large displays or calculators that make noise may result in you being moved to a different seat by the proctor.
These rules ensure that the SAT Calculator Policy maintains a level playing field for all test-takers.
Frequently Asked Questions (FAQ)
No. While most graphing calculators are allowed, those with a Computer Algebra System (CAS) are explicitly prohibited. Always check your specific model.
If a proctor identifies your calculator as prohibited, you will not be allowed to use it. You would have to take the math section without a calculator, which is a significant disadvantage.
Yes, all versions of the TI-84 Plus (including Plus, Silver Edition, C, CE) are approved as they are non-CAS models.
No. Phones, tablets, laptops, and smartwatches are strictly forbidden for use as calculators.
A scientific calculator handles numbers (trigonometry, logs, exponents). A CAS calculator can manipulate symbolic expressions (variables, algebra), which is why it’s banned under the SAT Calculator Policy.
Yes, the College Board requires you to remove any stored programs or documents from your calculator before the test.
If your calculator is not on a known approved or prohibited list, check it against the feature rules. As long as it doesn’t have CAS, a QWERTY keyboard, wireless, etc., it is likely allowed. Using our checker can help you make this determination.
Yes, the Desmos calculator provided in the Bluebook app is a powerful graphing calculator that is more than sufficient for the SAT. Many students find it very effective. It’s a good idea to practice with the public version of Desmos before the test.
