Start with the printed model name, not the store listing or classroom nickname.

i. Match the model

Open the exact Casio, Texas Instruments, or HP model printed on the calculator body.

ii. Check the exam

SAT, ACT, and FE rules differ. A calculator can be allowed on one exam and banned on another.

iii. Confirm the source

Each verdict links to the official policy source and shows when the answer was last verified.
