Can I Use My Graphing Calculator on the SAT?
Instantly check if your calculator is permitted on the digital SAT based on the latest College Board policy.
Rule Analysis
What is the SAT Calculator Policy?
The question “can i use my graphing calculator on the sat” is a critical one for test-day success. The College Board has a detailed SAT calculator policy that specifies which devices are allowed. For the digital SAT, you have two options: use the powerful built-in graphing calculator (provided by Desmos) or bring your own approved handheld calculator. While all math questions can be solved without a calculator, using a familiar device can boost speed and confidence. Calculators are only permitted on the Math section; they must be put away during the Reading and Writing section.
The core rule is that calculators must not provide an unfair advantage. This means devices with features like internet access, cameras, or computer-style (QWERTY) keyboards are strictly forbidden. Understanding the approved SAT calculators list is essential before your test date.
SAT Calculator Rules Explained
The eligibility of a calculator isn’t just about the model name; it’s about its features. The College Board’s rules are designed to prevent access to stored information or symbolic calculations that go beyond numerical computation. A key recent change is the ban on Computer Algebra Systems (CAS). Here are the core rules:
| Variable (Feature) | Meaning (What to Look For) | Unit (Status) | Typical Range (Impact) |
|---|---|---|---|
| Keyboard Style | Does it have a QWERTY (typewriter-style) keyboard? | Prohibited | Models like the TI-92 or Voyage 200 are banned for this reason. |
| CAS | Can it solve algebraic equations symbolically (e.g., factor x^2-1 into (x-1)(x+1))? Look for “CAS” in the model name. | Prohibited | As of 2025, all calculators with CAS are banned. This includes the TI-Nspire CX CAS and HP Prime. |
| Connectivity | Does it have Wi-Fi, Bluetooth, or any wireless communication capability? | Prohibited | No device that can communicate with other devices is allowed. |
| Power Source | Does it need to be plugged into an electrical outlet to work? | Prohibited | Only battery-operated calculators are permitted. |
| External Media | Does it use stylus pens, tapes, or have ports for external memory cards? | Prohibited | Devices like the Casio ClassPad series are not allowed due to their stylus input. |
Practical Examples
Let’s see how these rules apply to two common scenarios.
Example 1: Student with a TI-84 Plus
- Input: Calculator Model = TI-84 Plus
- Analysis: This model is a standard graphing calculator. It does not have a QWERTY keyboard, does not have a CAS, and has no wireless capabilities. It is battery-operated.
- Result: Permitted. This is one of the most common and widely accepted calculators for the SAT. For more info, check our SAT prep courses.
Example 2: Student with a TI-89 Titanium
- Input: Calculator Model = TI-89 Titanium
- Analysis: This model contains a Computer Algebra System (CAS), which allows it to perform symbolic algebra manipulations.
- Result: Not Permitted. Due to the updated SAT calculator policy, all calculators with CAS functionality are prohibited from use on the test.

Using this tool is simple and provides instant clarity on whether you can use your graphing calculator on the SAT.
- Select Your Model: Click the dropdown menu and find your calculator’s brand and model. The list includes the most common devices from Texas Instruments, Casio, and HP.
- View the Result: As soon as you select a model, the calculator will instantly display the result: “Permitted” or “Not Permitted”.
- Read the Explanation: The result includes a detailed reason based on the specific features of your selected model and the official College Board rules. This helps you understand the ‘why’ behind the decision.
- Reset and Compare: You can use the “Reset” button to clear the selection and check another model, allowing you to compare different calculators, which is useful when deciding on what calculators are allowed on the SAT.
Key Factors That Affect SAT Calculator Eligibility
Several critical factors determine if a calculator is approved. Being aware of these will help you avoid issues on test day.
- Computer Algebra System (CAS): This is a major disqualifier. CAS calculators can perform symbolic manipulation, which is considered an unfair advantage.
- QWERTY Keypad: Any calculator with a typewriter-style keyboard is banned.
- Wireless Communication: Devices with Bluetooth, infrared, or Wi-Fi are strictly prohibited. You must cover any infrared data ports with tape.
- Power Requirements: The calculator must be battery-powered. No devices that require an electrical outlet are allowed.
- Noise and Printing: Calculators that make noise or can print to paper are not permitted.
- External Devices: Laptops, mobile phones, smartwatches, and tablets are never allowed as a substitute for a calculator. Exploring math strategies for the SAT can help you rely less on complex functions.
Frequently Asked Questions (FAQ)
Yes, the entire TI-84 Plus family (including the CE and Python editions) is fully permitted. It is a standard graphing calculator without any prohibited features like CAS.
No. As of recent policy updates, calculators with a Computer Algebra System (CAS) are no longer allowed. You can use the non-CAS version, the TI-Nspire CX or CX II.
No. Mobile phones, smartwatches, laptops, or any device with communication capabilities are strictly forbidden. Using one will result in dismissal from the test.
The College Board requires that you remove any stored documents from your calculator. While proctors may not always check, it’s best practice to clear programs and data to comply with the rules.
You will not be allowed to use it during the test. If you don’t have an approved backup, you will have to take the Math section without a calculator or use the built-in digital one.
Yes, the policy for handheld calculators is the same. The main difference is that the digital SAT provides a built-in Desmos-powered graphing calculator for all students. You can choose to use that, your own, or both.
No. Calculator use is restricted to the Math section only. You must put your calculator away during all other sections of the test. This is a key difference in our ACT vs SAT comparison.
The most up-to-date rules are always on the official College Board website. It is highly recommended to check their page for the definitive SAT calculator policy before your test.
