What Are Calculators That Are Allowed on the SAT?
The term “calculators that are allowed on the sat” refers to the specific set of handheld electronic devices approved by the College Board for use on the Math section of the SAT. To ensure fairness, not all calculators are permitted. The policy generally allows most graphing calculators, all scientific calculators, and all four-function calculators. However, devices with features that could provide an unfair advantage, such as internet access or a computer-style (QWERTY) keyboard, are strictly forbidden.
Students should use this policy to verify their device is compliant before test day. While the Digital SAT includes a built-in graphing calculator (Desmos), students are still permitted and often encouraged to bring a familiar, approved handheld device. Understanding the list of calculators that are allowed on the sat is a critical step in test preparation.
SAT Calculator Rules and Logic
The College Board’s rules for calculators are not arbitrary; they are designed to prevent cheating and ensure a level playing field. The logic behind the restrictions is based on specific functionalities. Here’s a breakdown of the core principles determining which calculators are allowed on the SAT.
| Feature/Rule | Reasoning for Restriction | Status |
|---|---|---|
| No QWERTY Keyboard | Prevents typing and storing of notes or formulas. | Prohibited |
| No Wireless/Internet/Bluetooth | Prevents communication and access to external information. | Prohibited |
| No Stylus or Pen-Input | These devices often have computer-like functions beyond calculation. | Prohibited |
| No Electrical Outlet Required | Ensures logistical feasibility and fairness in all testing centers. Calculators must be battery-powered. | Prohibited |
| No Noise or Paper Tape | Prevents disruption to other test-takers. | Prohibited |
| Computer Algebra System (CAS) | As of August 2025, CAS is prohibited as it can perform symbolic algebra, which is seen as an unfair advantage. | Prohibited (Post-Aug 2025) |
| Graphing Capability | Generally permitted as it is a standard tool for advanced math. | Allowed |
Practical Examples
Let’s see how our SAT Approved Calculator Checker works with real-world examples.
Example 1: Checking a Prohibited Calculator
- Input: User types “TI-92 Plus” into the calculator.
- Output Status: NOT ALLOWED
- Interpretation: The tool identifies “TI-92” as a model with a QWERTY keyboard, which is explicitly banned. The student is advised to find an alternative from the list of calculators that are allowed on the sat.
Example 2: Checking an Approved Calculator
- Input: User types “TI-84 Plus CE” into the calculator.
- Output Status: ALLOWED
- Interpretation: The tool recognizes this as a standard, widely-used graphing calculator that fully complies with College Board policies. This is one of the most popular calculators that are allowed on the sat.
How to Use This SAT Approved Calculator Checker
Follow these simple steps to determine if your device is one of the calculators that are allowed on the sat.
- Enter Your Model: Type the complete model name of your calculator (e.g., “Casio fx-9750GII”) into the input field above.
- Review the Result: The tool will instantly provide one of three results: “Allowed,” “Not Allowed,” or “Check Manually.”
- Read the Details: The result will include a reason for the status, such as identifying a prohibited feature or confirming its compliance. For “Check Manually” results, you’ll be prompted to verify it against the key rules (no QWERTY, no internet, etc.).
- Plan Accordingly: If your calculator is not allowed, you must acquire an approved model before your test date. Refer to our guide on choosing a graphing calculator for help.
Key Factors That Affect SAT Calculator Approval
Understanding these six factors is crucial for ensuring you bring one of the approved calculators that are allowed on the sat to your exam.
| Factor | Allowed Models | Prohibited Models |
|---|---|---|
| Keyboard Type | Standard numeric keypad (e.g., TI-84 Plus, all scientific calculators) | QWERTY (keyboard-like) layouts (e.g., TI-92 Plus, Voyage 200) |
| Connectivity | No wireless capabilities | Anything with Wi-Fi, Bluetooth, or cellular access |
| Input Method | Physical buttons | Stylus, pen-input, or touch-screen (e.g., Casio ClassPad) |
| Power Source | Battery operated (AAA, solar, or rechargeable) | Devices requiring an external power cord |
| Advanced Functions (CAS) | Standard graphing (non-CAS). Note: Pre-August 2025, some CAS was allowed. | Calculators with a Computer Algebra System (CAS) like the TI-Nspire CX II CAS are banned from August 2025 onwards. |
| Form Factor | Handheld devices | Laptops, mobile phones, tablets, or smartwatches |
Frequently Asked Questions (FAQ)
1. Is the TI-Nspire CX II CAS allowed on the SAT?
No. Beginning with the August 2025 SAT, calculators with Computer Algebra System (CAS) functionality are prohibited. You should use the non-CAS version, the TI-Nspire CX II. This is a significant update to the list of calculators that are allowed on the sat.
2. Do I need to bring a calculator for the Digital SAT?
While the Digital SAT provides a powerful built-in Desmos graphing calculator, you are still allowed to bring your own approved device. Many students prefer using a physical calculator they are already familiar with. Check the Digital SAT changes for more info.
3. Are all scientific calculators allowed on the SAT?
Yes, as a category, all standard scientific calculators are permitted. They do not have the advanced prohibited features like QWERTY keyboards or internet connectivity.
4. What happens if I bring a banned calculator to the test?
You will not be allowed to use it. If you are caught using a prohibited device during the test, you will be dismissed, and your scores will be canceled. It is your responsibility to ensure you have one of the calculators that are allowed on the sat.
5. Can I use my phone’s calculator?
No. Mobile phones, smartwatches, laptops, and any device with communication capabilities are strictly prohibited.
6. Is the TI-89 Titanium allowed?
The TI-89 has a CAS. Under the new policy effective August 2025, it will be prohibited. Before that date, it was allowed. Always check the official College Board calculator rules for the most current policy.
7. Do I need to clear my calculator’s memory?
The College Board policy states you do not need to clear the memory, but you must remove any programs that have CAS-like functionality or stored documents.
8. Is a four-function calculator good enough for the SAT?
While it is technically on the list of calculators that are allowed on the sat, it is not recommended. Many questions on the Math section are solved much more efficiently with a graphing or scientific calculator.
