What is the SAT Calculator Policy?
The SAT calculator policy refers to the set of rules established by the College Board that dictates whether a student can use a calculator for the SAT, and if so, what types and under what conditions. The primary rule is that calculators are only permitted during the Math section of the exam. They are strictly forbidden during the Reading and Writing section. The policy is designed to ensure fairness and prevent any student from having an unfair technological advantage. Understanding if you can use a calculator for the SAT is crucial for test day readiness. For the digital SAT, an advanced graphing calculator (Desmos) is built directly into the testing application, available for all students during the Math section. However, students are still permitted to bring their own approved device.
SAT Calculator Rules Explained
There isn’t a mathematical formula to determine if you can use a calculator for the SAT, but a logical decision process based on official rules. The determination depends on two main factors: the test section and the calculator’s features. Calculators are never allowed on the Reading and Writing section. On the Math section, most graphing, scientific, and four-function calculators are allowed, provided they do not have any prohibited features. The most significant disqualifying feature is a Computer Algebra System (CAS).
Decision Factors
| Variable | Meaning | Allowable State (Math Section) | Typical Range |
|---|---|---|---|
| Test Section | The part of the SAT being taken. | Must be ‘Math Section’ | Math, Reading & Writing |
| CAS Functionality | Ability to manipulate algebraic expressions symbolically. | Must be ‘No’ | Yes / No |
| QWERTY Keyboard | A computer-style keyboard. | Must be ‘No’ | Yes / No |
| External Power | Requires an electrical outlet. | Must be ‘No’ (Battery only) | Battery / Power Cord |
| Connectivity | Wi-Fi, Bluetooth, Cellular, etc. | Must be ‘No’ | Yes / No |
Practical Examples (Real-World Use Cases)
Example 1: Student with a TI-84 Plus
- Inputs: Section = Math, Prohibited Features = None checked.
- Output: ALLOWED.
- Interpretation: The Texas Instruments TI-84 Plus is a standard graphing calculator without CAS functionality. It is one of the most common and recommended calculators and is fully compliant with the SAT calculator policy for the Math section.
Example 2: Student with a TI-89 Titanium
- Inputs: Section = Math, Prohibited Features = “Has a Computer Algebra System (CAS)” is checked.
- Output: NOT ALLOWED.
- Interpretation: The TI-89 has a powerful CAS, which is explicitly banned by the College Board. A student trying to use this device would be in violation of the rules, even on the Math section. Knowing whether you can use a calculator for the SAT depends heavily on this CAS rule.
How to Use This SAT Calculator Policy Checker
This tool simplifies the process of checking if you can use a calculator for the SAT.
- Select the Section: Choose whether you are in the “Math Section” or “Reading & Writing Section” of the SAT.
- Identify Prohibited Features: Review the list of checkboxes. If your calculator has any of these features (like a QWERTY keyboard or CAS), check the corresponding box.
- Review the Result: The tool will instantly display “ALLOWED” or “NOT ALLOWED” with an explanation based on your selections and the official College Board rules.
- Reset if Needed: Click the “Reset” button to clear the inputs and start over with a different calculator or scenario.
Key Factors That Affect Calculator Approval
- Computer Algebra System (CAS): This is the most critical factor. Calculators with CAS, like the TI-Nspire CAS, are explicitly prohibited. You must ensure your device is a non-CAS model.
- QWERTY Keyboards: Any device with a typewriter-style keyboard is not allowed. This prevents the use of devices that are essentially small computers.
- Connectivity: Calculators with Wi-Fi, Bluetooth, infrared, or any other wireless communication capability are banned to prevent cheating.
- Power Source: The device must be battery-powered. Calculators that need to be plugged into an electrical outlet are not permitted in the testing room.
- Device Type: Laptops, tablets, smartphones, and smartwatches are not calculators and are strictly forbidden.
- Stylus / Pen Input: Models that require a stylus or pen for operation are generally not allowed.
Frequently Asked Questions (FAQ)
Yes, a powerful graphing calculator provided by Desmos is integrated directly into the Bluebook testing app for the digital SAT. You can use it for the entire Math section.
Yes, even with the built-in Desmos calculator, you are still allowed to bring your own approved handheld calculator. Many students prefer using a physical device they are more familiar with.
The model name often includes “CAS” (e.g., TI-Nspire CX II CAS). If it can solve algebraic equations with variables (like solving x + 2y = 4 for x) rather than just numbers, it likely has CAS.
Yes, all standard scientific calculators are allowed on the Math section. They are a good option if you don’t need graphing capabilities.
Using a banned device or using a calculator on the wrong section can lead to your dismissal from the test and the cancellation of your scores.
While not always enforced, the policy states you should remove any stored programs or documents. It is a good practice to reset your calculator before the test.
No. Sharing calculators is strictly forbidden. Each student must have their own device.
While allowed, a four-function calculator is not recommended. The SAT Math section contains problems where a scientific or graphing calculator is highly advantageous.
