What is the SAT Calculator Policy?
A common question students ask is, “can you use a graphing calculator on the SAT?“. The answer is yes, but with important restrictions. The College Board, which administers the SAT Suite of Assessments (including the Digital SAT, PSAT/NMSQT, PSAT 10, and PSAT 8/9), has a detailed calculator policy to ensure fairness and test security. For the Digital SAT, every student has access to a powerful built-in graphing calculator (powered by Desmos) for the entire Math section. However, students are also permitted to bring their own handheld calculator. Understanding whether your device is compliant is crucial. The fundamental rule is that your calculator must be a dedicated calculating device without features common to smartphones or computers. This policy exists so that no student has an unfair advantage. Therefore, knowing if you can use a graphing calculator on the SAT depends entirely on its specific features.
How the College Board Determines Calculator Approval
The College Board doesn’t approve specific models one-by-one. Instead, it provides a list of prohibited features. Any calculator with one or more of these features is banned. This “feature-based” policy simplifies the question of whether you can use a graphing calculator on the SAT. The logic is straightforward: if your calculator has a feature on the “no” list, it’s not allowed. The most significant recent change is the ban on calculators with a Computer Algebra System (CAS).
| Variable / Feature | Meaning | Status | Typical Range / Example |
|---|---|---|---|
| Internet/Wireless | Any form of wireless communication (Wi-Fi, Bluetooth). | Prohibited | Any device that can connect to the web. |
| QWERTY Keyboard | A computer-style keyboard. | Prohibited | Models like the TI-92 Plus. |
| CAS Functionality | Computer Algebra System, which can solve algebra symbolically. | Prohibited | TI-Nspire CX II CAS, HP Prime. |
| Stylus / Pen Input | Touch-screen models that use a stylus. | Prohibited | Casio ClassPad series. |
| Power Source | Device must be battery-operated. | Mains Power Prohibited | Calculators with power cords are not allowed. |
| Device Type | Must be a dedicated calculator. | Phones/Laptops Prohibited | You cannot use a smartphone, tablet, or laptop. |
Practical Examples
Example 1: A Compliant Calculator (TI-84 Plus)
A student has a Texas Instruments TI-84 Plus. They use the checker and confirm it has none of the prohibited features: no QWERTY keyboard, no internet, no CAS, no stylus. The calculator is battery-powered.
Inputs: All prohibited feature boxes are unchecked.
Output: The result is “Allowed.” The student can confidently bring this calculator to the test. This is a classic example that answers “yes” to “can you use a graphing calculator on the SAT“.
Example 2: A Prohibited Calculator (HP Prime with CAS)
Another student has an HP Prime calculator. While it’s a powerful graphing calculator, this model includes a Computer Algebra System (CAS).
Inputs: The student checks the “Does it have a Computer Algebra System (CAS)?” box.
Output: The result is “Not Allowed.” The reason provided is the presence of CAS functionality. This student will need to use the built-in Desmos calculator or find a different, non-CAS handheld calculator.
How to Use This SAT Calculator Policy Checker
- Select Your Test: Choose the test you are taking from the dropdown. The policy is the same for all tests in the Digital SAT Suite.
- Check for Prohibited Features: Go through the list of checkboxes. For each question, inspect your physical calculator. If it has the described feature (like a QWERTY keyboard or internet access), check the box.
- Review Your Results: As soon as you check a box, the result will update in real-time. If the status changes to “Not Allowed,” the tool will list the specific reason(s) why.
- Reset if Needed: If you want to start over or check another calculator, simply click the “Reset” button.
- Make a Decision: If your calculator is allowed, you are all set! If not, you should plan to use the integrated Desmos calculator available in the Bluebook testing app or acquire a compliant model. Knowing if you can use a graphing calculator on the SAT before test day prevents unnecessary stress.
Key Factors That Affect Calculator Approval
- Computer Algebra System (CAS): This is a major disqualifier. CAS can perform symbolic algebraic manipulation (like factoring x²-4 into (x-2)(x+2)), which the College Board now considers an unfair advantage.
- QWERTY Keypad: Calculators with computer-style keyboards are not permitted as they could potentially be used to store notes. This has been a long-standing rule.
- Internet & Wireless Connectivity: Any device that can communicate wirelessly (Bluetooth, Wi-Fi, cellular) is strictly forbidden to prevent any possibility of cheating.
- Power Source: Calculators must be battery-powered. You cannot use a device that needs to be plugged into an outlet during the test.
- Stylus and Touchscreens: Pen-input or stylus-operated devices are not allowed. This is to maintain a standardized hardware environment.
- Device Type: The device must be a dedicated calculator. You cannot use a laptop, mobile phone, smartwatch, or tablet in place of a calculator.
Ultimately, the core principle behind whether you can use a graphing calculator on the SAT is ensuring test fairness and security.
Frequently Asked Questions (FAQ)
Yes, the entire TI-84 Plus series (including Plus, C Silver Edition, CE) is allowed because it does not have any of the prohibited features like CAS or a QWERTY keyboard. It is one of the most popular choices for students.
It depends on the model. The TI-Nspire CX (non-CAS) is generally allowed. However, the TI-Nspire CX CAS and CX II CAS are not allowed due to their Computer Algebra System. You must check your model carefully.
No, it’s not required. The Digital SAT testing application (Bluebook) has a built-in Desmos graphing calculator that is available for every question in the Math section. Many students find it powerful and sufficient. However, if you are more comfortable with your own handheld calculator, you are allowed to bring an approved one.
Yes, the College Board states that all scientific calculators are permitted, as they do not have the advanced, prohibited functionalities of some graphing calculators. However, they are less powerful than graphing calculators.
No. Using a mobile phone, smartwatch, tablet, or any other general-purpose computing device as a calculator is strictly prohibited.
If the proctor identifies your calculator as prohibited, you will not be allowed to use it. You would have to take the Math section using only the built-in calculator. It’s crucial to check your device beforehand.
While allowed, four-function calculators are very limited. They often lack functions for trigonometry (sin, cos, tan), exponents, and roots, which can be very helpful for some SAT Math questions.
The College Board no longer publishes a comprehensive “approved list.” Instead, they list prohibited features. The best approach is to check their official SAT Calculator Policy page and use a checker tool like this one to confirm if you can use a graphing calculator on the SAT.
