| Smartphone / iPhone / Android device | Prohibited | Has wireless capabilities, QWERTY keyboard, and is a general-purpose computer. |
What is the SAT Calculator Policy?
The SAT calculator policy outlines the rules for using a calculator on the SAT Math with Calculator section. The purpose is to ensure fairness and prevent any student from having an unfair advantage. While you can use a calculator, not all devices are allowed. The College Board, which administers the SAT, specifies that calculators cannot have features that could compromise the integrity of the test. For the digital SAT, a graphing calculator (Desmos) is built into the testing application, but you are still permitted to bring your own approved device.
The most critical rule is that your calculator must be a dedicated, battery-operated device. Prohibited items include laptops, tablets, smartwatches, and mobile phones. The policy primarily targets features like internet access, computer algebra systems (CAS), and QWERTY keyboards. Understanding whether you can use a graphing calculator on the SAT depends entirely on its specific features.
The SAT Permissibility “Formula”
Think of the SAT calculator policy not as a math formula, but as a logical checklist. For a calculator to be permitted, it must pass through several checks. If it fails any single check, it is prohibited.
The core logic is:
Permitted = (Is NOT on Prohibited List) AND (Has NO Prohibited Features)
The “variables” in this formula are the features of the calculator itself. Before the test, you must verify each of these for your device.
| Variable / Feature | Meaning | Status if Present | Typical Range |
|---|---|---|---|
| Computer Algebra System (CAS) | The ability to manipulate algebraic expressions symbolically (e.g., factor `x^2-4` into `(x-2)(x+2)`). | Prohibited | Found in models like TI-89, TI-Nspire CAS, HP Prime. |
| QWERTY Keyboard | A full typewriter-style keyboard for typing text. | Prohibited | Found on older models like the TI-92. |
| Wireless Capability | Features like Bluetooth, Wi-Fi, or any form of internet/network access. | Prohibited | All smartphones, tablets, and smartwatches. |
| External Power | A need for an electrical outlet to function. | Prohibited | Laptops and some very old printing calculators. Must be battery-operated. |
| Noise or Printing | Calculators that make audible sounds or print to a paper tape. | Prohibited | Mainly older, office-style calculators. |

Practical Examples
Let’s see how the policy applies to common scenarios for students wondering if they can use a graphing calculator on the SAT.
Example 1: The Standard Approved Calculator
- Input Model: TI-84 Plus CE
- Feature Check: No QWERTY, no CAS, no wireless, battery-operated.
- Result: Permitted. This is one of the most common and recommended calculators for the SAT.
Example 2: The Prohibited CAS Calculator
- Input Model: TI-Nspire CX II CAS
- Feature Check: The “CAS” in the name stands for Computer Algebra System. This is an explicitly prohibited feature.
- Result: Prohibited. Even though the non-CAS version is allowed, the presence of CAS makes this model banned.
Example 3: The Ambiguous Older Model
- Input Model: HP-48G
- Feature Check: This model is older and might not be familiar. A check of the official College Board list is necessary. Some HP models like the HP Prime are banned due to CAS.
- Result: Requires Verification. It’s crucial to check the official SAT Calculator Policy list. Ambiguity can lead to problems on test day.
How to Use This SAT Calculator Checker
This tool helps you quickly determine if your graphing calculator is likely to be allowed on the SAT. Follow these simple steps:
- Enter Your Calculator’s Model: Type the model name (e.g., “Casio fx-9750GIII”) into the first input field. This helps the tool check against a list of known models.
- Answer the Feature Questions: Go through the list of checkboxes. For each question, check the box if your calculator has that specific feature. Be honest—this is key to getting an accurate assessment.
- Check the Status: Click the “Check Status” button. The tool will evaluate your inputs based on the College Board’s rules.
- Review the Result: The result box will appear, color-coded for clarity:
- Green (Permitted): Your calculator appears to meet all requirements.
- Red (Prohibited): Your calculator has a feature that is explicitly banned by the SAT calculator policy.
- Yellow (Potentially Permitted/Check Official List): The model wasn’t recognized, but no prohibited features were selected. You MUST double-check with the official College Board list.
- Reset for a New Check: Click the “Reset” button to clear the form and check another calculator. For further reading, see SAT Prep Courses.
Key Factors That Affect SAT Calculator Permissibility
Several key factors determine whether you can use a graphing calculator on the SAT. Understanding them is crucial for test day.
- 1. Computer Algebra System (CAS): This is the most significant factor. CAS functionality can solve algebraic equations symbolically, which the College Board deems an unfair advantage. As of recent policy updates, all CAS calculators are banned.
- 2. QWERTY Keyboards: Any calculator with a typewriter-style keyboard is strictly prohibited to prevent the storage of notes.
- 3. Connectivity: Calculators with any form of wireless communication (Bluetooth, Wi-Fi, infrared) are banned. This is why smartphones and tablets are not allowed.
- 4. Power Source: The device must be battery-powered. Calculators that require an external power source, like a laptop, are not permitted.
- 5. Physical Attributes: Devices that make noise, print, have a stylus (with few exceptions), or are oversized may be prohibited or lead to special seating arrangements.
- 6. Official Lists: The College Board maintains an official, though not exhaustive, list of approved and prohibited calculators. Always refer to this as the final source of truth. See our guide to College Application Advice for more resources.
Frequently Asked Questions (FAQ)
1. Can I use a TI-84 Plus on the SAT?
Yes, the entire TI-84 Plus family (including CE, Plus, Silver Edition) is permitted on the SAT as they do not have a Computer Algebra System (CAS). It’s one of the most recommended calculators.
2. Is the TI-Nspire CAS allowed on the SAT?
No. Any calculator with “CAS” in its name, including the TI-Nspire CAS and TI-89, is explicitly prohibited from the SAT.
3. What happens if I bring a prohibited calculator?
If a proctor identifies your calculator as prohibited, you may be forced to take the test without it, or in more serious cases, you could be dismissed from the test and have your scores canceled.
4. Do I need to use a graphing calculator on the SAT?
No, it is not required. All questions can be solved without a calculator. Additionally, the digital SAT includes an on-screen Desmos graphing calculator. However, being proficient with your own approved calculator can be faster and more comfortable. Explore Free SAT Practice materials to see how it works.
5. Can I use a scientific calculator on the SAT?
Yes, all scientific calculators are permitted, as long as they don’t have any of the prohibited features (like wireless connectivity).
6. Can I use my phone as a calculator?
No. Phones, tablets, laptops, and any device with communication capabilities are strictly forbidden.
7. Where can I find the official College Board calculator policy?
You can find the most up-to-date and official policy on the SAT Suite of Assessments website, usually under a section titled “What to Bring” or “Calculator Policy.”
8. Do I need to clear my calculator’s memory?
While proctors may not always check, the official policy requires that you remove any stored documents or programs. It is a good practice to clear the memory before test day to avoid any potential issues.
