SAT Calculator Policy Checker: Can You Use Wexford Calculators on the SAT?
A tool to help you determine if your Wexford calculator model likely meets the College Board’s rules for use on the SAT exam.
Eligibility Checker
Answer the following questions about your calculator’s features to see if it’s likely permitted.
Entering the model name helps with record-keeping but does not change the logic.
Check the box if your calculator has any of these features.
What is the Official SAT Calculator Policy?
The College Board, which administers the SAT, has a specific policy regarding calculators to ensure fairness. While students are encouraged to bring a calculator they are familiar with, it must comply with the rules. The digital SAT even includes a built-in Desmos graphing calculator. Generally, most graphing calculators, all scientific calculators, and all four-function calculators are permitted. However, the key is that they must not be on the prohibited list.
A calculator is prohibited if it has features like wireless communication, a computer-style (QWERTY) keyboard, or requires an external power source. As of recent updates, calculators with a Computer Algebra System (CAS) are also banned because they provide an unfair advantage by solving algebraic expressions symbolically.
Wexford Calculators and the SAT
So, can you use Wexford calculators on the SAT? The answer is: most likely, yes.
“Wexford” is a brand name, often for basic or scientific calculators, rather than a single model. These types of calculators are almost always allowed on the SAT. Basic four-function and scientific calculators sold under the Wexford brand typically do not have the complex features that the College Board prohibits, such as QWERTY keyboards or internet connectivity.
However, you are responsible for confirming your specific model is compliant. The best way to be sure is to use the eligibility checker above and compare your calculator’s features against the official SAT prohibited features list.
Formula and Explanation
The “formula” for determining if a calculator is allowed isn’t mathematical, but logical. A calculator is permitted if, and only if, it meets two conditions:
- It is a recognized type (Graphing, Scientific, or 4-Function).
- It does NOT possess any prohibited features.
Our checker automates this logical process. If any prohibited feature is present, the result is “Not Permitted.”
| Feature | Status | Reasoning |
|---|---|---|
| Basic Arithmetic (+, -, *, /) | Permitted | Standard on all calculators. |
| Scientific Functions (sin, log, ^) | Permitted | All scientific calculators are allowed. |
| Graphing Functions | Permitted | Most graphing calculators are allowed. |
| QWERTY Keyboard | Not Permitted | Resembles a computer, which is banned. |
| Internet/Bluetooth Access | Not Permitted | Can be used to access outside information. |
| Computer Algebra System (CAS) | Not Permitted | Solves equations symbolically, giving an unfair advantage. |
| Requires Electrical Outlet | Not Permitted | Calculators must be battery-operated. |
Practical Examples
Example 1: A Standard Wexford Scientific Calculator
- Inputs: A student has a “Wexford Scientific Calculator”. They run through the checklist.
- Feature Check: It does not have a QWERTY keyboard, internet, CAS, or any other prohibited feature.
- Result: The eligibility checker shows Likely Permitted. The student can bring it to the test with confidence.
Example 2: A Hypothetical Prohibited Calculator
- Inputs: A student finds a calculator that has “CAS” in its model name.
- Feature Check: They check the box for “Does it have a Computer Algebra System (CAS)?”.
- Result: The eligibility checker immediately shows Not Permitted. This calculator cannot be used on the SAT.
How to Use This SAT Calculator Policy Checker
- Inspect Your Calculator: Carefully look at your Wexford calculator. Check the keypad layout and look for any symbols indicating wireless connectivity.
- Answer the Questions: Use the checklist in the calculator above. Check the box for each feature your calculator has.
- Review the Result: The tool will instantly provide a result: “Likely Permitted” or “Not Permitted.”
- Read the Explanation: The text below the result will explain why your calculator received that status, based directly on the official SAT rules.
Key Factors That Affect Calculator Eligibility
Understanding these factors is crucial for making sure you’re prepared on test day.
- Computer Algebra System (CAS): This is a major disqualifier. These systems can manipulate algebraic expressions and solve equations symbolically, which is not allowed.
- QWERTY Keypad: Any calculator with a typewriter-like keyboard is banned.
- Connectivity: Any form of wireless communication (internet, Bluetooth, cellular) is strictly forbidden.
- Power Source: Calculators must be battery-operated. Models that require an electrical outlet are not permitted.
- Device Type: You cannot use a calculator that is part of a phone, tablet, or computer. You must use the built-in Desmos calculator or a separate, handheld device.
- Stylus/Pen-Input: Calculators that use a stylus are generally not permitted.
Frequently Asked Questions (FAQ)
- 1. What if I bring a prohibited calculator to the SAT?
- The test proctor will not allow you to use it. You would have to take the math section without a calculator or use the built-in one.
- 2. Are all scientific calculators allowed on the SAT?
- Yes, the College Board states that all scientific calculators are acceptable, provided they do not have any prohibited features like CAS.
- 3. Do I need a graphing calculator for the SAT?
- It is not required, but often recommended. The digital SAT provides a built-in Desmos graphing calculator for all students.
- 4. Is a basic Wexford 8-digit calculator good enough for the SAT?
- While a four-function calculator is permitted, it is not recommended as it lacks functions like exponents and logarithms which might be useful. A scientific calculator is a better choice.
- 5. Where can I find the official list of approved calculators?
- The College Board does not provide a comprehensive list of every single approved model. Instead, they provide a list of prohibited features. If your calculator does not have any prohibited features, it is allowed.
- 6. Can I share my calculator with another student?
- No. Sharing calculators is strictly forbidden and can lead to dismissal from the test.
- 7. What is a Computer Algebra System (CAS)?
- It’s a feature on high-end calculators that can solve and simplify algebraic equations symbolically (e.g., turning `(x+1)(x-1)` into `x^2-1`). This is banned on the SAT.
- 8. Do I need to clear my calculator’s memory?
- Yes, it’s a good practice to clear the memory of your calculator before the test, as storing programs or notes is not allowed.
