SAT Calculator Policy Checker
A quick and easy tool to determine if you can use a calculator on the SAT math sections based on the latest College Board rules.
Is Your Calculator Allowed?
Enter your calculator’s model and check any features it has. Our tool will assess its compliance with the SAT’s official policy.
SAT Math Section Breakdown
The Digital SAT, which has replaced the paper version, allows a calculator on the entire Math section. The test consists of two Math “modules.” You are permitted to use an approved calculator for both of them. There is no longer a “No-Calculator” section.
What is the SAT Calculator Policy?
The SAT calculator policy is a set of rules established by the College Board to ensure fairness and prevent any unfair advantages during the test. While you can use a calculator on the SAT math test, not all calculators are permitted. The primary goal is to standardize the testing environment, meaning the tool should assist with calculations, not provide algebraic solutions or external information. Knowing whether you can use your calculator on the SAT Math section is critical for test day success.
Prohibited Features and Rules
The core of the policy isn’t a list of “allowed” models, but rather a list of “prohibited” features. If your calculator has any of the following, you cannot use it on the SAT:
- Devices that can connect to the internet, have Bluetooth, or any other form of wireless communication.
- Calculators with a QWERTY (computer-style) keyboard.
- Calculators that are part of a phone, tablet, or computer.
- Models that use a stylus, are touchscreen (with some exceptions), or make noise.
- Devices that need to be plugged into an electrical outlet.
- Starting in 2025, calculators with a Computer Algebra System (CAS) are banned.
Calculator Status Formula Explained
This tool determines your calculator’s status using the following logic:
IF (IsPhone OR HasQwerty OR HasWireless OR HasStylus OR NeedsPower OR HasCAS OR IsProhibitedModel) THEN Status = PROHIBITED, ELSE Status = PERMITTED.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| IsProhibitedModel | The calculator model name is on the official banned list. | Text Match | e.g., “TI-92”, “HP Prime” |
| HasCAS | The calculator has Computer Algebra System functionality. | Boolean (Yes/No) | Yes or No |
| HasQwerty | The calculator has a computer-style keyboard. | Boolean (Yes/No) | Yes or No |
| HasWireless | The calculator can communicate wirelessly (WiFi, Bluetooth). | Boolean (Yes/No) | Yes or No |
Practical Examples
Example 1: A Permitted Calculator
- Inputs: Model: “TI-84 Plus”, No prohibited features checked.
- Units: N/A. The check is based on features.
- Result: PERMITTED. The TI-84 Plus does not have any of the prohibited features. It is a standard graphing calculator widely used for the SAT.
Example 2: A Prohibited Calculator
- Inputs: Has a QWERTY keyboard? = YES.
- Units: N/A.
- Result: PROHIBITED. Calculators with computer-style keyboards are not allowed as they can be used for text entry.
How to Use This SAT Calculator Checker
- Enter Your Model: Type your calculator’s model name into the first field. This helps identify models that are explicitly banned.
- Check for Features: Carefully review the list of prohibited features. Check the box next to any feature your calculator has. Be honest—it’s better to know now than on test day.
- Analyze the Results: Click “Check My Calculator”. The result will tell you if your device is likely permitted or prohibited and why. For more information, check out these SAT Prep Tips.
- Interpret the Outcome: A “PROHIBITED” result means you need to get a different calculator for the test. A “PERMITTED” result means you are likely safe, but always double-check the official College Board SAT calculator policy.
Key Factors That Affect Calculator Choice for the SAT
- Familiarity: The best calculator is one you already know how to use. Don’t buy a new, complex calculator right before the exam.
- Functionality: A good graphing calculator can be a powerful tool. It can graph functions, find intersections, and solve systems of equations, which can be faster than doing it by hand.
- Battery Life: Your calculator must be battery-operated. Make sure you have fresh batteries before test day. Proctors will not supply them.
- CAS vs. Non-CAS: This is now a critical distinction. A CAS (Computer Algebra System) can manipulate expressions symbolically (e.g., factor `x^2-1`). This is a powerful advantage and is why CAS calculators are being banned. Explore our guide on Best SAT Calculators.
- Built-in Desmos: The digital SAT includes a built-in Desmos graphing calculator. It is very powerful, so it’s a good idea to practice with it even if you bring your own.
- Portability and Condition: Make sure your calculator is in good working order and easy to transport.
Frequently Asked Questions (FAQ)
1. Can you use a calculator on the whole SAT math section?
Yes, for the Digital SAT, you are allowed to use an approved calculator on the entire Math section.
2. What happens if I bring a prohibited calculator?
You will not be allowed to use it. In the worst-case scenario, you could be dismissed from the test and your scores canceled.
3. Is my TI-89 or TI-Nspire CAS allowed?
No. Both the TI-89 and TI-Nspire CAS models are explicitly prohibited because they have a Computer Algebra System (CAS).
4. Do I have to clear my calculator’s memory?
It’s a good practice. The rules state you must remove any programs or documents with algebra functionality. Some test centers may require you to clear the memory. To learn more, see our article about SAT Math Strategies.
5. Are scientific calculators allowed?
Yes, all standard scientific calculators are allowed.
6. Can I use the calculator on my phone?
No. Phones, smartwatches, tablets, and laptops are strictly forbidden for use as calculators.
7. What’s the difference between a CAS and a regular graphing calculator?
A regular graphing calculator works with numbers (e.g., it can find the value of `sin(45)`). A CAS calculator works with symbols (e.g., it can simplify `(x+y)^2` to `x^2 + 2xy + y^2`). This symbolic manipulation gives an unfair advantage, which is why CAS is banned. Learn more from our Math Tutoring Services.
8. Should I bring my own calculator or just use the built-in one?
It’s highly recommended to bring a physical calculator you are familiar with, even though the built-in Desmos calculator is excellent. You might be faster with your own device. This is a key part of any good Online SAT Course.
