SAT Calculator Policy Checker
Check Your Calculator’s Eligibility
Unsure if you can use your graphing calculator on the SAT? This tool helps you check your device against the official SAT Calculator Policy. Select its features to see if it’s likely to be permitted.
Providing a model helps identify specifically banned calculators like the TI-92.
Your calculator’s eligibility status will be shown here based on the selected features.
This chart visualizes which features are prohibited by the SAT Calculator Policy. Red bars indicate banned features.
What is the SAT Calculator Policy?
The **SAT Calculator Policy** is a set of rules established by the College Board to ensure fairness and test security during the SAT Suite of Assessments. This policy dictates which calculators are allowed and which are prohibited in the Math section of the test. While students can bring their own approved calculator, for the digital SAT, there is also a powerful graphing calculator built directly into the testing application (Bluebook™). The primary goal of the **SAT Calculator Policy** is to prevent any student from having an unfair advantage through devices with advanced communication, note-taking, or symbolic algebra capabilities. Understanding these rules is critical for a smooth test day experience.
Most graphing calculators, scientific calculators, and four-function calculators are permitted. However, devices with features like a QWERTY keyboard, internet access, or a Computer Algebra System (CAS) are strictly forbidden. The policy ensures that the test measures a student’s mathematical reasoning skills, not their ability to operate a mini-computer. Following the **SAT Approved Calculators** list is non-negotiable.
SAT Calculator Rules and Prohibited Features Explained
The logic behind the **SAT Calculator Policy** is straightforward: prevent access to unauthorized information and capabilities. The rules specifically target features that go beyond numerical calculation. Here’s a step-by-step breakdown of why certain features are banned.
The following table outlines the key variables (prohibited features) that determine a calculator’s eligibility.
| Feature (Variable) | Meaning | Status | Typical Range/Example |
|---|---|---|---|
| QWERTY Keyboard | A typewriter-style keyboard for entering text. | Prohibited | TI-92, HP-95LX |
| Computer Algebra System (CAS) | Software that manipulates mathematical expressions symbolically. | Prohibited | TI-Nspire CAS, HP Prime |
| Wireless/Internet | Any feature that can communicate externally (Bluetooth, Wi-Fi, cellular). | Prohibited | Smartphones, tablets |
| Requires Power Cord | Device cannot operate solely on batteries. | Prohibited | Laptops, plug-in devices |
| Stylus/Pen-Input | Touch-screen devices that use a stylus for input. | Prohibited | Casio ClassPad series |
| Makes Noise / Prints | Calculators that have audio features or a paper tape printer. | Prohibited | Printing calculators |

Practical Examples (Real-World Use Cases)
Let’s apply the **SAT Calculator Policy** to two popular calculator models to determine their eligibility.
Example 1: Texas Instruments TI-84 Plus
- Inputs: No QWERTY keyboard, no CAS, no wireless, battery-operated, no stylus.
- Analysis: The TI-84 Plus is a standard graphing calculator. It lacks all the major prohibited features. It has a long history of being one of the most common **SAT approved calculators**.
- Output: ✅ Allowed. This calculator is a safe and reliable choice for the SAT math section.
Example 2: Texas Instruments TI-Nspire CX II CAS
- Inputs: Has a Computer Algebra System (CAS) as indicated by its name.
- Analysis: The College Board explicitly prohibits calculators with CAS functionality. Although the non-CAS version (TI-Nspire CX II) is allowed, the CAS model’s ability to solve algebraic equations symbolically gives it an unfair advantage according to the **College Board calculator rules**.
- Output: ❌ Not Allowed. Due to the CAS feature, this specific model is banned from use on the SAT.
How to Use This SAT Calculator Policy Checker
This tool simplifies the process of checking your device against the official **SAT Calculator Policy**. Follow these steps:
- Enter Model (Optional): Type your calculator’s model name. The tool can identify some explicitly banned models.
- Check Prohibited Features: Go through the list of checkboxes. For each question, check the box if your calculator has that feature.
- Review the Result: The tool will instantly update the status. “Allowed” (green) means it appears to comply, while “Not Allowed” (red) means it has a prohibited feature.
- Understand the Explanation: The text below the result tells you exactly which rule your calculator violates. Check out our digital SAT guide for more test-day tips.
- Analyze the Chart: The bar chart provides a quick visual reference of all prohibited features, helping you better understand the overall **SAT Calculator Policy**.
Key Factors That Affect SAT Calculator Eligibility
Several key factors determine whether you can use a graphing calculator on the SAT. Being aware of these will help you choose the right tool for the **SAT math section**.
- Computer Algebra System (CAS): This is the most critical factor. A CAS can perform symbolic algebra, which is a tested skill. The policy requires you to solve these problems yourself. Therefore, any calculator with CAS is banned.
- QWERTY Keyboard: Devices with typewriter-style keyboards are prohibited because they can be used to store notes or formulas, compromising test security.
- Communication Technology: Any calculator that can connect to the internet, cellular networks, or other devices via Bluetooth or infrared is strictly forbidden to prevent cheating. This is a cornerstone of the **SAT Calculator Policy**.
- Power Source: Calculators must be battery-operated. Devices that require an external power source, like a wall outlet, are not allowed in the testing room.
- Physical Form Factor: The policy prohibits devices that are essentially mini-computers, such as laptops, tablets, and smartphones, regardless of their “calculator mode.”
- Stylus or Pen Input: Devices that require a stylus are generally banned as they often have advanced functionalities beyond the scope of a standard calculator, such as handwriting recognition. Getting familiar with the right tools is part of effective SAT prep courses.
Frequently Asked Questions (FAQ)
1. Can I use a TI-84 Plus on the SAT?
Yes, the entire TI-84 Plus family (including the CE version) is permitted as it does not have a CAS. It is one of the most popular and recommended **SAT approved calculators**.
2. Is the calculator policy the same for the digital SAT?
Yes, the policy for bringing your own calculator is the same. However, the digital SAT also includes a built-in Desmos graphing calculator in the testing app, which you can use instead of or alongside your own. Understanding the **calculator on SAT** options is key.
3. What happens if I bring a banned calculator?
The proctor will not allow you to use it. You may have to take the math section without a calculator, or your scores could be canceled. It is your responsibility to ensure your device complies with the **SAT Calculator Policy**.
4. Do I have to clear my calculator’s memory before the test?
Yes, the College Board requires you to remove any stored programs or documents that have algebra functionality. While proctors may not inspect every calculator, it is a firm rule. A guide to **prohibited calculators for SAT** can be found on the official site.
5. Are four-function calculators allowed?
Yes, but they are not recommended. The SAT math section contains problems where a scientific or graphing calculator is highly beneficial. Relying on a four-function calculator could put you at a significant time disadvantage. For more insights, see our article on SAT math strategies.
6. Can I share my calculator with another student?
No. Sharing calculators is strictly prohibited during the test.
7. What are the rules for calculators with large displays?
If your calculator has characters one inch or larger, or a raised display that might be visible to others, the proctor may seat you in a specific location to maintain test security. This detail is part of the official **College Board calculator rules**.
8. Is a TI-89 allowed on the SAT?
No. The TI-89 and TI-92 models are explicitly banned because they contain a Computer Algebra System (CAS). When considering a **graphing calculator SAT**, always check for the CAS feature.
