Allowed Sat Calculators

Verify if your device meets College Board requirements for the Digital SAT.

What are Allowed SAT Calculators?

Allowed sat calculators refer to the specific list of electronic computing devices permitted by the College Board for use during the Math section of the SAT exam. Since the transition to the Digital SAT (DSAT), every student has access to a built-in Desmos graphing calculator directly within the Bluebook™ testing application. However, many students prefer to bring their own handheld allowed sat calculators to maintain familiarity and speed.

The core philosophy behind allowed sat calculators is to ensure fairness while allowing students to utilize technology to solve complex problems. Whether you use a TI-84 Plus, a Casio Prizm, or a simple scientific model, the device must not have features that compromise test security, such as wireless communication or QWERTY keyboards.

Common misconceptions include the idea that “CAS” (Computer Algebra System) calculators are banned—they are actually permitted on the SAT, unlike the ACT. Another myth is that you cannot bring a backup; in reality, you can bring extra allowed sat calculators, though only one may be on your desk at a time.

Allowed SAT Calculators Formula and Compliance Logic

There is no mathematical “formula” for compliance, but rather a set of logical filters that a device must pass to be considered among allowed sat calculators. We can represent this as a Boolean logic gate:

Compliance = (Not Prohibited Model) AND (No QWERTY) AND (No Internet) AND (Battery Powered) AND (No Stylus)

Variable	Meaning	Requirement	Allowed Range
Keyboard Type	Layout of keys	Non-QWERTY	Standard Numeric/Alpha
Connectivity	Data transfer capability	Offline only	No WiFi, Bluetooth, or Cell
Power Source	How the device runs	Internal Power	Battery or Solar
Display	Screen type	Non-Ink/Non-Paper	LCD, LED, OLED
Input Device	Method of interaction	Button/Finger	No Stylus/Electronic Pen

Practical Examples (Real-World Use Cases)

Example 1: The TI-84 Plus CE User

A student brings a Texas Instruments TI-84 Plus CE to the testing center. They check the allowed sat calculators requirements.
Input: Graphing capability, no QWERTY, battery-powered.
Result: Fully compliant. This device is highly recommended for the SAT because its color screen helps differentiate between multiple graphed functions, potentially saving 10-15 seconds per question compared to a scientific model.

Example 2: The Prohibited Device Scenario

A student attempts to use a TI-92 which features a full QWERTY keyboard.
Input: Graphing capability, QWERTY keyboard present.
Result: Prohibited. Even though it is a powerful calculator, the keyboard makes it a “computer-like” device, disqualifying it from the list of allowed sat calculators.

How to Use This Allowed SAT Calculators Checker

1. Select your calculator brand from the dropdown menu (e.g., Texas Instruments, Casio).
2. Type in your specific model number. This is crucial as specific versions (like CAS vs non-CAS) might have different hardware.
3. Tick the boxes for any special features your device has. If you check “QWERTY Keyboard,” the tool will immediately flag the device as prohibited.
4. Review the “Device Capability Score.” A higher score (80-100%) indicates a graphing calculator that provides maximum advantage for the allowed sat calculators policy.
5. Click “Copy Compliance Report” to save your results for your test-day checklist.

Key Factors That Affect Allowed SAT Calculators Results

• Keyboard Configuration: Devices with letter keys in a QWERTY layout are strictly forbidden because they facilitate unauthorized note-taking.
• Wireless Communication: Any device capable of accessing the internet via WiFi or cellular data is not among allowed sat calculators due to cheating risks.
• Stylus Usage: Calculators that require a pen or stylus for operation are generally banned because they are classified as personal digital assistants (PDAs).
• Screen Technology: While standard screens are fine, any device with a printer or paper tape is prohibited in the testing room.
• Power Requirements: You cannot plug your device into a wall outlet. Allowed sat calculators must be battery-operated or solar-powered.
• Model Exclusions: Specific old models (like the HP-95LX) are explicitly named as prohibited by the College Board regardless of their features.

Frequently Asked Questions (FAQ)

1. Is the TI-Nspire CAS an allowed sat calculator?

Yes! Unlike the ACT, the SAT allows all models of the TI-Nspire, including the CAS (Computer Algebra System) versions.

2. Can I use my phone’s calculator app?

No. Mobile phones, tablets, and smartwatches are strictly prohibited, even if you are using a calculator app.

3. What happens if my calculator dies during the test?

Proctors are not required to provide batteries or backup calculators. You should bring extra batteries or a second backup from the allowed sat calculators list.

4. Is Desmos better than a handheld calculator?

The built-in Desmos is extremely powerful for the Digital SAT. However, many students prefer a physical device for tactile speed and avoiding toggling between screens.

5. Do I need to clear my calculator memory?

While the College Board allows allowed sat calculators to have programs, some proctors may ask you to clear RAM or show that no prohibited notes are stored.

6. Are “Scientific” calculators always allowed?

Yes, as long as they don’t have wireless capabilities or a QWERTY keyboard. All standard scientific calculators are allowed sat calculators.

7. Can I bring a calculator with a touch screen?

Only if it does not require a stylus. The Casio ClassPad series is often problematic if it relies on a stylus for input.

8. Does the proctor check the model number?

Yes, proctors are trained to identify prohibited models. Using a non-allowed device can result in your scores being canceled.
