SAT Calculator Policy Explained
| Feature Type | Status | Explanation |
|---|---|---|
| Graphing Capability | Allowed | Most graphing calculators are permitted. They are useful for visualizing functions. |
| Scientific Functions | Allowed | All standard scientific calculators are allowed for the exam. |
| Computer Algebra System (CAS) | Prohibited | Calculators that can perform symbolic manipulation (e.g., factor, solve for variables) are NOT allowed. |
| QWERTY Keyboard | Prohibited | Any device with a computer-style keyboard is not permitted. |
| Wireless/Internet Access | Prohibited | Calculators that can connect to the internet or other devices are strictly forbidden. |
| Stylus or Pen Input | Prohibited | Calculators requiring a stylus or pen for input are not allowed. |
| Makes Noise or Prints | Prohibited | Devices that make noise or have a paper tape printer cannot be used. |
What is the SAT Calculator Policy?
The SAT calculator policy refers to the set of rules established by the College Board that dictates what calculators can be used on the SAT. The primary goal of this policy is to ensure fairness and equity among all test-takers, preventing anyone from gaining an unfair advantage through superior technology. It defines which types of calculators (four-function, scientific, graphing) are acceptable and explicitly lists features that are prohibited, such as wireless communication, QWERTY keyboards, and Computer Algebra Systems (CAS). Understanding what calculators can be used on the SAT is crucial for test day preparation.
This policy should be reviewed by every student planning to take the SAT. While the digital SAT includes a built-in Desmos graphing calculator, students are still permitted and often encouraged to bring their own familiar device. Common misconceptions include believing that the most expensive calculator is necessary for a high score or that all graphing calculators are automatically allowed. The rules on what calculators can be used on the SAT are specific, and knowing them prevents test-day surprises.
SAT Calculator Policy Rules and Guidelines
Instead of a mathematical formula, the question of what calculators can be used on the SAT is governed by a logical framework of rules. The College Board outlines permitted devices and prohibited features. The core principle is that the calculator should be a tool for computation, not for storing information or performing symbolic algebraic manipulation.
Key Rule Variables
Here’s a breakdown of the “variables” that determine a calculator’s eligibility:
| Variable (Feature) | Meaning | Allowed Range | Typical Status |
|---|---|---|---|
| Calculator Type | The device’s primary function. | Graphing, Scientific, Four-Function | Most models are allowed. |
| CAS | Computer Algebra System. | Must be ‘No’. | Prohibited. Many advanced models have this. |
| Keyboard Style | The layout for text input. | Numeric keypad only. | QWERTY keyboards are prohibited. |
| Connectivity | Ability to communicate externally. | None (No Wi-Fi, Bluetooth, Infrared). | Prohibited. |
| Power Source | How the calculator is powered. | Battery only. | Devices requiring an electrical outlet are prohibited. |
Practical Examples (Real-World Use Cases)
Example 1: A Standard Graphing Calculator
- Input: TI-84 Plus CE
- Output: Allowed
- Interpretation: This is one of the most common and recommended calculators. It has graphing capabilities but does not have a prohibited CAS or a QWERTY keyboard, making it a perfect example of what calculators can be used on the SAT.
Example 2: A Calculator with a Prohibited Feature
- Input: TI-Nspire CX II CAS
- Output: Not Allowed
- Interpretation: Although it’s a powerful calculator, the “CAS” in its name stands for Computer Algebra System. As of recent policy updates, CAS functionality is explicitly prohibited, making this model ineligible for the SAT. This highlights the importance of checking the exact model name.
Example 3: A Smartphone
- Input: iPhone with Calculator App
- Output: Not Allowed
- Interpretation: Smartphones are strictly prohibited. They have wireless connectivity, cameras, QWERTY keyboards, and access to other applications, all of which are forbidden under the SAT calculator policy.
How to Use This SAT Calculator Eligibility Checker
This tool simplifies the process of determining what calculators can be used on the SAT. Follow these steps:
- Enter Your Calculator Model: Type the full model name found on your calculator (e.g., “Casio fx-9750GII”) into the input field.
- Review the Instant Result: The tool will immediately display one of three statuses: “Allowed,” “Not Allowed,” or “Check Features.”
- Read the Details: The intermediate results provide context, such as the calculator’s category and any specific notes related to its eligibility.
- Make Your Decision: If your calculator is allowed, you’re all set! If not, you will need to acquire an approved model for test day. If the status is “Check Features,” you must manually verify it against the prohibited features list.
Key Factors That Affect Calculator Eligibility
Several critical factors determine what calculators can be used on the SAT. A deviation in any of these can render a calculator ineligible.
- Computer Algebra System (CAS): This is the most significant factor. A CAS can solve equations symbolically, which the College Board deems an unfair advantage. All CAS calculators are banned.
- QWERTY Keyboard: Calculators with a typewriter-style keyboard are not allowed as they could potentially be used to store notes.
- Wireless Communication: Any feature that allows communication with other devices, such as Bluetooth, infrared, or Wi-Fi, is strictly forbidden to prevent cheating.
- Power Source: Only battery-operated calculators are permitted. Devices that need to be plugged into an electrical outlet are not allowed in the test center.
- Stylus/Touch Screen: Calculators that use a stylus for input are generally prohibited. Some touch screen models without stylus input may be allowed, but it’s a gray area that requires careful checking.
- Hardware Peripherals: You cannot connect any external devices to your calculator, such as printers, cables, or storage drives.
Frequently Asked Questions (FAQ)
If your calculator model is not explicitly listed, it is your responsibility to ensure it does not have any prohibited features. As long as it’s a standard scientific or graphing calculator without CAS, a QWERTY keyboard, or wireless capabilities, it is likely allowed.
Test proctors may ask you to clear your calculator’s memory. You should be prepared to do so. It is against the rules to store formulas or notes on your device.
Yes, all scientific calculators are allowed and are sufficient for the SAT. While a graphing calculator can make some problems faster to solve, it is not a requirement for a top score.
The College Board banned CAS calculators to ensure fairness, as these devices provide a significant advantage in solving complex algebra problems symbolically, which moves beyond the intended scope of a calculation aid.
No. Smartwatches and any other wearable technology are strictly prohibited.
The “best” calculator is one you are comfortable and familiar with. The TI-84 Plus series is extremely popular and widely recommended because it balances powerful features with SAT compliance.
Yes, you can bring a backup calculator. However, you can only have one calculator on your desk at a time.
Yes, the digital SAT testing application (Bluebook) includes an embedded Desmos graphing calculator that you can use on the entire math section.
