SAT Calculator Policy Checker
An interactive tool to determine if your calculator is permitted on the SAT, based on the official can you use scientific calculator sat rules.
Is Your Calculator SAT-Approved?
Check the features of your calculator below. According to the official SAT calculator policy, devices with certain features are prohibited. This tool helps you check your device against these rules.
Calculators with typewriter-like keyboards are not allowed.
Any device with wireless communication capabilities is banned.
CAS performs symbolic algebra (e.g., factoring `x^2-1`). These are now banned.
Only battery-operated calculators are permitted.
Pen-input devices are generally prohibited.
Calculators that make sounds are not allowed.
Calculators with a paper tape are banned.
Visualizing Calculator Compliance

What is the SAT Calculator Policy?
The SAT calculator policy is a set of rules established by the College Board that dictates which calculators are acceptable for use during the SAT exam. The primary goal of this policy is to ensure fairness and prevent any student from having an unfair technological advantage. It specifies that while most scientific calculators and many graphing calculators are allowed, any device with features like a computer algebra system (CAS), internet connectivity, or a QWERTY keyboard is strictly prohibited. Understanding the nuances of the can you use scientific calculator sat rules is critical for test-day success.
Many students mistakenly believe any scientific calculator is automatically fine, but that’s not always the case. The policy focuses on functionality, not just the “scientific” label. A device is judged by its features. Therefore, knowing the specific capabilities of your calculator is more important than its brand or model name. This is a core component of preparing for the SAT math section.
SAT Calculator Policy Formula and Mathematical Explanation
The “formula” for determining if a calculator is allowed isn’t mathematical but logical. It’s a series of conditional checks. A calculator is deemed “Prohibited” if it possesses any single feature from the banned list. The logic can be expressed as:
IF (Has_QWERTY OR Has_Internet OR Has_CAS OR Needs_Power OR Has_Stylus OR ...) THEN Status = "Prohibited" ELSE Status = "Likely Allowed"
This simple binary logic ensures a level playing field. Below is a breakdown of the “variables” in this equation, which are the features the SAT calculator policy scrutinizes.
| Variable (Feature) | Meaning | Status | Typical Range (Yes/No) |
|---|---|---|---|
| Computer Algebra System (CAS) | Can manipulate algebraic expressions symbolically. | Prohibited | No |
| Internet/Wireless | Can connect to Wi-Fi, Bluetooth, or cellular networks. | Prohibited | No |
| QWERTY Keyboard | A typewriter-style keyboard. | Prohibited | No |
| External Power Requirement | Needs to be plugged into an outlet to function. | Prohibited | No |
| Scientific Functions | Performs trig, log, and exponential functions. | Allowed | Yes |
| Graphing Functions | Can plot coordinates and graph equations. | Allowed (if non-CAS) | Yes |
Practical Examples (Real-World Use Cases)
Let’s apply the SAT calculator policy to a few real-world examples to see how the rules work.
Example 1: Texas Instruments TI-84 Plus CE
- Inputs: No QWERTY, No Internet, No CAS, Battery-powered.
- Analysis: This popular graphing calculator is on the College Board’s approved list. It has graphing capabilities but lacks the prohibited CAS feature. It meets all requirements.
- Output: Allowed. It is a perfect example of an acceptable graphing calculator for the SAT.
Example 2: A Standard Smartphone Calculator App
- Inputs: Has a touch screen (stylus-capable), has internet, often has a QWERTY keyboard for other apps.
- Analysis: A smartphone fails on multiple counts. Its ability to connect to the internet is an automatic disqualification. This is a clear violation of the can you use scientific calculator sat rules.
- Output: Prohibited. No phones are allowed as calculators.
How to Use This SAT Calculator Policy Checker
Using this calculator is a straightforward process to ensure your device complies with the SAT calculator policy.
- Inspect Your Calculator: Carefully examine your calculator for each feature listed in the checker above.
- Check the Boxes: For each feature your calculator possesses, click the corresponding checkbox.
- Review the Result: The tool will instantly provide a result: “Likely Allowed” or “Prohibited”.
- Read the Details: The intermediate results section will explain exactly which feature caused the “Prohibited” status, giving you a clear understanding of the violation.
- Make a Decision: If your calculator is prohibited, you must acquire an approved one for test day. Refer to the {related_keywords} for a list of accepted models.
Key Factors That Affect SAT Calculator Eligibility
Several key factors determine whether your calculator is allowed. Understanding these is vital for complying with the SAT calculator policy.
- Computer Algebra System (CAS): This is the most significant recent change. As of 2025, calculators with CAS are banned because they can solve algebraic equations symbolically, providing an unfair advantage.
- Wireless Connectivity: Any device that can communicate wirelessly is banned. This prevents any possibility of receiving outside help during the exam.
- QWERTY Keyboards: These keyboards make it possible to store notes, which is why they are on the prohibited list. The policy is strict on this point.
- Power Source: Calculators must be battery-operated. This ensures the test environment is free of cables and potential electrical issues.
- Physical Size and Display: Devices with very large, raised displays might require special seating to prevent other test-takers from seeing your work.
- Making Noise: Any audible feature must be disabled. A noisy calculator can distract other students, compromising the testing environment.
Frequently Asked Questions (FAQ)
Yes, the entire TI-84 Plus series (including the CE) is allowed because it does not have a Computer Algebra System (CAS). It is one of the most common and recommended calculators.
It depends. The TI-Nspire CX (non-CAS) is allowed, but the TI-Nspire CX II CAS is explicitly prohibited due to its CAS functionality. You must check the model name carefully.
Your proctor will not allow you to use it. You will have to take the math section without a calculator or use the built-in one on the digital SAT, which might be unfamiliar to you.
No. All mobile phones are banned from the testing room, regardless of their mode. This is a strict rule in the SAT calculator policy.
While most are, it’s not a guarantee. A scientific calculator could theoretically have a prohibited feature. The key is to check its functions against the can you use scientific calculator sat rules, not just its name.
Yes, proctors may ask you to clear the memory on your calculator before the test begins to ensure no notes or formulas are stored.
If it’s not on a prohibited list and doesn’t have any banned features (like CAS, Wi-Fi, etc.), it is likely allowed. Use our checker above to be sure. When in doubt, have a backup from the approved {related_keywords} list.
No. Calculator use is restricted to the Math section only. You must put it away during all other sections of the test.
