SAT® Calculator Policy Checker
An interactive tool to help determine if your calculator, including solar-powered models, is permitted for use on the SAT® exam.
Is Your Calculator SAT-Approved?
Answer the following questions about your calculator’s features to check its compliance with the current SAT policy.
The SAT only permits battery-operated, handheld calculators. Solar calculators are generally acceptable as they are battery-powered.
As of recent updates, calculators with CAS functionality are prohibited. This is a critical rule.
Calculators with typewriter-like keyboards are not allowed.
Any device that can communicate wirelessly is strictly forbidden. Infrared ports must be covered.
Only dedicated handheld calculators are permitted.
Calculators must be silent. All audio features must be turned off.

What is the SAT Calculator Policy?
The SAT calculator policy outlines the rules for which types of calculators students can use during the Math section of the exam. The goal is to ensure fairness and prevent any student from having an unfair advantage. While you can bring your own calculator, it must meet specific guidelines set by the College Board. The question, “can solar calculators be used on the sat,” is common because these devices are reliable and environmentally friendly. The short answer is yes, provided they meet all other criteria. The SAT requires calculators to be battery-operated, and solar power is considered a form of battery operation.
However, the power source is just one factor. Prohibited features include Computer Algebra Systems (CAS), QWERTY keyboards, wireless connectivity, and being part of another device like a phone or tablet. Understanding these rules is crucial for a smooth test day experience. Our SAT Calculator Policy Checker above can help you quickly verify your device.
SAT Calculator Rules and Explanation
To determine if a calculator is allowed, you must check its features against a list of prohibited items. There isn’t a single “formula,” but rather a checklist of compliance points. A failure on any single point means the calculator is not allowed. This is especially true for the ban on Computer Algebra Systems (CAS), which is a major policy point.
| Feature / Rule | Meaning | Status | Typical Range / Value |
|---|---|---|---|
| Power Source | How the calculator is powered. | Allowed | Battery or Solar |
| Power Cord | Requires plugging into an outlet. | Prohibited | N/A |
| Computer Algebra System (CAS) | Can manipulate algebraic expressions symbolically. | Prohibited | e.g., TI-Nspire CX II CAS |
| QWERTY Keyboard | A typewriter-style keyboard layout. | Prohibited | e.g., TI-92 Plus |
| Wireless Capability | Bluetooth, Wi-Fi, or other wireless tech. | Prohibited | Any |
| Part of Another Device | Is a feature of a phone, tablet, etc. | Prohibited | e.g., Phone Calculator App |
Practical Examples
Example 1: A Compliant Solar Calculator
A student wants to bring a basic Texas Instruments TI-108 solar-powered calculator. Let’s check its compliance.
- Inputs: Power Source (Solar), No CAS, No QWERTY, No Wireless, Standalone Device, No Noise.
- Result: Allowed. This calculator meets all the criteria. It’s a simple, non-programmable, battery-operated device perfect for the SAT.
Example 2: A Prohibited Graphing Calculator
A student has an HP Prime graphing calculator.
- Inputs: Power Source (Battery), Yes CAS, No QWERTY, No Wireless, Standalone Device, No Noise.
- Result: Not Allowed. Although it meets most criteria, the presence of a Computer Algebra System (CAS) makes this calculator prohibited on the SAT. This is a critical detail many students miss. For more on this, see our guide on advanced SAT math prep.

- Review the Result: The tool will instantly provide a result: “Allowed” or “Not Allowed.”
- Understand the Explanation: The result includes a brief explanation detailing which specific rule your calculator passed or failed. This helps you understand the official SAT policy better.
- Reset if Needed: If you want to check another calculator, simply press the “Reset” button to clear the inputs. You can find more details in our Test Day Checklist.
Key Factors That Affect SAT Calculator Approval
When asking “can solar calculators be used on the sat,” several factors beyond the power source come into play. Understanding these is key to avoiding issues on test day.
- CAS Functionality: This is the most significant recent change. Calculators that can solve algebraic equations symbolically are banned.
- Keyboard Layout: Any calculator with a QWERTY keyboard is prohibited to prevent students from typing notes.
- Connectivity: No device with internet, Bluetooth, or infrared capabilities is allowed. It must be a completely offline device.
- Device Type: The device must be a dedicated calculator. Phones, smartwatches, and tablets are not permitted, even if you only use the calculator app.
- Physical Characteristics: Calculators that make noise or have large, raised displays may lead to seating adjustments by the proctor. All sounds must be off.
- Power Source: It must be battery or solar-powered. Devices requiring an external power source are not allowed. For tips on what to bring, check our guide on what to bring to the SAT.
Frequently Asked Questions (FAQ)
1. Are all solar calculators allowed on the SAT?
No. A solar calculator is only allowed if it meets all other SAT requirements, such as having no CAS, no QWERTY keyboard, and no wireless capabilities. The solar power source itself is acceptable.
2. What is a Computer Algebra System (CAS) and why is it banned?
A CAS is a sophisticated program that can perform symbolic math, like factoring polynomials or solving for variables. It was banned to ensure the test assesses a student’s mathematical reasoning, not their ability to use a powerful tool.
3. Can I use the calculator on the entire SAT?
No. Calculator use is only permitted on the designated Math with Calculator section. For the digital SAT, an on-screen calculator (Desmos) is also available.
4. What if my calculator has an infrared port?
The College Board requires you to cover any infrared data ports with opaque tape to prevent any possibility of communication.
5. Is a graphing calculator better than a scientific calculator for the SAT?
Not necessarily. While a graphing calculator can be helpful for visualizing functions, all questions on the SAT can be solved without one. A familiar scientific calculator is often sufficient. Consider our graphing calculator guide for more info.
6. What happens if I bring a prohibited calculator?
If you are found with a prohibited calculator, you may be dismissed from the test, and your scores could be canceled. It’s crucial to check your calculator beforehand.
7. Can I bring a backup calculator?
Yes, you can bring a backup calculator. However, it also must be an approved model. You must keep it under your desk when not in use.
8. Where can I find the official list of approved calculators?
The College Board website maintains the most current SAT calculator policy and lists of example allowed and disallowed models. It’s the ultimate source of truth. Check out our page of official SAT resources.
