Quick answers
Calculator policy questions, answered before test day.
These summaries are for orientation. Each model-specific verdict links to the current official source used for that exam and shows the date it was last checked.
Q.01What calculators are allowed on the SAT?
The SAT permits graphing, scientific, and 4-function calculators subject to College Board restrictions. Start with the SAT hub or an exact model verdict, then confirm the current College Board policy before test day.
Q.02How do I check whether a calculator is allowed on the ACT?
Use the ACT exam hub or search for the exact printed model name. ACT rules can depend on CAS capability, communication features, apps, and test-day instructions, so this guide ties each answer back to the official policy source.
Q.03Which calculators are approved for the NCEES FE exam?
NCEES uses a strict approved-calculator list. This guide currently covers FE verdicts for common Casio, Texas Instruments, and HP models, including the fx-991, fx-115, TI-30X, TI-36X, and HP 35s families.
Q.04Why does the exact calculator model matter?
Similar retail names can hide important differences such as CAS, graphing, programming, wireless, or app-based behavior. Match the model printed on the physical calculator, not only a marketplace title or classroom nickname.
