B) “Can You Use Your Own Calculator on the SAT?” Policy Logic and Explanation

Unlike a traditional mathematical formula, determining “can you use your own calculator on the SAT” involves a logical evaluation against a set of predefined rules and criteria established by the College Board. The “formula” here is a decision-making process that assesses a calculator’s type, model, and features for compliance.

Step-by-Step Derivation of Policy Check:

1. Initial Allowance Check: Most standard four-function, scientific, and graphing calculators are generally allowed as a baseline.
2. Prohibited Features Scan: The policy then checks for specific features that are universally disallowed, regardless of the calculator’s type or model. These include QWERTY keyboards, wireless communication, audio/video recording/playback, paper tape, and requiring an electrical outlet. The presence of any of these immediately renders the calculator prohibited.
3. Model-Specific Restrictions: Certain advanced graphing calculators, particularly those with Computer Algebra Systems (CAS), are often restricted. Examples include the TI-89 Titanium and the original TI-Nspire CAS. Even if a calculator is a “graphing calculator,” this specific functionality can lead to disqualification.
4. “Other” Category Review: If a calculator falls into an “Other” or unknown category, it triggers a recommendation for the student to double-check with the College Board directly, as its status is not immediately clear.
5. Final Determination: Based on the absence of prohibited features and adherence to model-specific guidelines, a final “Allowed” or “Disallowed” status is determined.

Variable Explanations:

The “variables” in this policy check are the characteristics of your calculator that are evaluated.
