SAT Calculator Permissibility Checker
An essential tool for students preparing for the SAT. Find out if your device is one of the calculators permitted on sat with our easy-to-use checker and comprehensive policy guide.
Is Your Calculator Allowed on the SAT?
What Are Calculators Permitted on SAT?
The term “calculators permitted on sat” refers to the specific set of rules and approved device lists published by the College Board for use during the Math Test – Calculator portion of the SAT. Not all calculators are allowed; the policy is designed to ensure fairness and prevent any student from having an unfair advantage through technology. Understanding these rules is crucial for test day success. Generally, most graphing calculators and all scientific calculators are acceptable. However, devices with features like a computer algebra system (CAS), wireless communication, or a QWERTY keyboard are strictly prohibited.
This policy applies to both the traditional paper SAT and the Digital SAT. For the Digital SAT, an embedded Desmos graphing calculator is available within the testing application (Bluebook™), but students are still allowed to bring their own approved handheld device. Familiarity with either the built-in tool or your own device is a key part of an effective SAT strategy.
The “Formula” for a Permitted Calculator
There isn’t a mathematical formula, but rather a logical one based on a set of criteria. The permissibility of a calculator is determined by its features. You can think of the rule as:
Permitted = (Is a Graphing OR Scientific OR 4-Function Calculator) AND (NOT has a Computer Algebra System (CAS)) AND (NOT has a QWERTY keyboard) AND (NOT has wireless/internet access) AND (NOT has a stylus/pen input) AND (NOT a phone, tablet, or laptop)
Key Variables in the Permissibility Decision
| Variable / Factor | Meaning | Typical Status |
|---|---|---|
| Calculator Type | The category of the calculator (Graphing, Scientific, etc.). | Graphing & Scientific are generally OK. |
| CAS Functionality | Computer Algebra System, which can solve algebra symbolically. | Strictly PROHIBITED. Models with “CAS” in the name are banned. |
| QWERTY Keyboard | A computer-style keyboard. | Strictly PROHIBITED (e.g., TI-92 models). |
| Connectivity | Features like Wi-Fi, Bluetooth, or cellular data. | Strictly PROHIBITED. |
| Power Source | How the calculator is powered. | Must be battery-operated. No power cords allowed. |
Practical Examples of SAT Calculator Checks
Example 1: The Standard Graphing Calculator
- Student’s Calculator: Texas Instruments TI-84 Plus
- Analysis: This is a very common graphing calculator. It does not have a CAS, a QWERTY keyboard, or any wireless capabilities.
- Result: PERMITTED. This is a classic example of one of the most widely used calculators permitted on sat.
Example 2: The Prohibited CAS Calculator
- Student’s Calculator: Texas Instruments TI-Nspire CX II CAS
- Analysis: While the non-CAS version (TI-Nspire CX II) is allowed, this model explicitly includes “CAS” in its name, which stands for Computer Algebra System.
- Result: PROHIBITED. The CAS functionality gives an unfair advantage and is banned by the College Board.
How to Use This Permissibility Calculator
- Enter Model Name: Type the full model name of your calculator into the input field above. For example, “Casio fx-9750GII”.
- Check Status: Click the “Check Status” button. The tool will compare your input against the official list of rules for calculators permitted on sat.
- Review Results: The tool will display a clear status: PERMITTED, PROHIBITED, or CHECK DETAILS for models that require special attention (e.g., some features must be disabled).
- Understand the Details: The intermediate results section explains *why* your calculator has a certain status, referencing its features against the SAT policy.

Key Factors That Affect Permissibility
Understanding the nuances of the policy on calculators permitted on sat can prevent test-day surprises. Here are the most critical factors:
- Computer Algebra System (CAS): This is the number one disqualifier. CAS can perform symbolic manipulation (e.g., factor x²-1 into (x-1)(x+1)), which is forbidden. Models like the TI-89, TI-Nspire CAS, and HP Prime are prohibited for this reason.
- QWERTY Keypad: Any device with a computer-style keyboard is not allowed. This is to prevent students from typing notes. This rule makes models like the TI-92 Plus and Voyage 200 unacceptable.
- Wireless Communication: Calculators with infrared, Bluetooth, or Wi-Fi capabilities are strictly banned to prevent communication between test-takers.
- Stylus or Pen-Based Input: Devices that require a stylus, like some older Casio ClassPad models, are not permitted.
- Hardware Type: The device must be a dedicated calculator. Phones, tablets, smartwatches, and laptops are never allowed, even if you are only using their calculator app.
- Power Source: Only battery-operated calculators are allowed. Devices that need to be plugged into an electrical outlet are prohibited.
Frequently Asked Questions (FAQ)
1. Can I use my TI-84 Plus on the SAT?
Yes, the TI-84 Plus (including the CE version) is one of the most popular and fully approved calculators permitted on sat. It does not have CAS functionality.
2. Is the TI-Nspire allowed?
It depends. The standard TI-Nspire CX and CX II models are permitted. However, the TI-Nspire CX CAS and CX II CAS models are strictly prohibited due to their Computer Algebra System.
3. What happens if I bring a prohibited calculator?
The test proctor will not allow you to use it. You will have to take the calculator section of the math test without a calculator, which could be a significant disadvantage. You will not be dismissed for simply bringing it, but you cannot use it.
4. Do I have to clear the memory on my calculator?
The College Board requires that you remove any stored programs or documents that have algebra functionality. It’s best practice to clear your calculator’s RAM before the test to be safe.
5. Is a scientific calculator good enough for the SAT?
Yes, a scientific calculator is sufficient. While a graphing calculator can be faster for some problems (like finding intersections of graphs), no question on the SAT requires a graphing calculator to be solved. Using a familiar scientific calculator is a valid strategy.
6. Can I use the calculator on all sections of the SAT?
No. Calculator use is only permitted on the “Math Test – Calculator” section. For the Digital SAT, the calculator is available for the entire Math section. You cannot use it on the Reading and Writing section.
7. Are all Casio calculators permitted on the SAT?
Not all. Most Casio scientific calculators (like the fx-115ES PLUS) and many graphing calculators (like the fx-9750GIII) are fine. However, Casio models with CAS, like the ClassPad series, are prohibited.
8. Can I share my calculator with another student?
No. Sharing calculators is strictly forbidden during the exam. Each student must bring their own approved calculator.
