3 approved verdicts and 0 banned verdicts currently published.
ClassWiz scientific calculator with natural textbook display, equation tools, matrix tools, and no graphing or CAS feature.
College Board says scientific calculators are permitted for SAT Math, while CAS calculators, phone apps, computers, wireless devices, and symbolic algebra programs are prohibited. The stored calculator data describes the Casio fx-991CW as a standalone non-CAS scientific calculator, so this verdict applies that feature-based policy to the exact physical model.
“Graphic, scientific, and 4-function calculators are allowed, subject to the restrictions below.”
Based on the cited policy quote from ACT Inc., the relevant evidence is that the policy allows the calculator category used by the Casio fx-991CW while separate restrictions still apply. The stored calculator data describes this model as a standalone scientific calculator and records whether it has CAS. This note does not approve apps, emulators, future variants, or use outside the exam context described in the verdict.
“4-function, scientific, and graphing models are allowed, unless prohibited per the list above.”
Based on the cited NCEES whitelist quote, the relevant evidence is the named calculator family or model. The Casio fx-991CW is matched to the Casio fx-991 family using the stored calculator model data. This evidence note does not treat every scientific calculator as allowed; it only explains why this exact printed model name fits the whitelist language currently recorded for the FE exam.
