01Do not bring the TI-Nspire CX II CAS to SAT Math as a fallback for the non-CAS TI-Nspire CX II; the CAS label changes the verdict.
02Bluebook Desmos is available during Digital SAT Math, but that does not permit a separate prohibited CAS handheld calculator.
03Check the front label, box, receipt, startup screen, and marketplace title because TI-Nspire CX II and TI-Nspire CX II CAS can be confused.
04Do not rely on Press-to-Test, disabled documents, cleared memory, reset settings, or hidden CAS menus to make the CAS model acceptable.
05If your school lends calculators, request the non-CAS model by exact name instead of accepting a generic Nspire calculator.
06Practice replacement workflows for graphing, tables, statistics, equation solving, fractions, trig, and degree-radian conversion before test day.
07Do not assume a case color, charger style, or family nickname proves approval; the CAS marking is the important policy difference.
08If a marketplace title says TI-Nspire CX II but product photos show CAS, treat the listing as risky and avoid using that unit for SAT.
09For timed practice, rebuild document-based workflows as simple graph, table, calculator memory, Desmos, and scratch-paper steps.
10If a teacher uses a CAS model for demonstrations, ask for a non-CAS practice path so exam-day keystrokes match the device you can actually bring.
11Check any school loaner form or calculator inventory list for the full model name, because abbreviated entries may hide the CAS suffix.
12Before final practice tests, verify your replacement handles zoom, trace, lists, regression, intersection estimates, decimal rounding, and battery replacement.
13If an online answer says TI-Nspire is allowed, check whether it means the non-CAS model rather than the CAS model covered on this page.
14Leave the CAS model outside the testing room to avoid check-in delays or score-cancellation risk.
15Recheck College Board's current policy close to your test date because this page is a dated editorial summary.
