The TI-84 Plus CE is not in the NCEES 2026 approved calculator families; Texas Instruments approval is limited to TI-30X and TI-36X models.
Based on the cited NCEES policy, this verdict treats the Texas Instruments TI-84 Plus CE as banned for the FE exam because the controlling rule is whitelist membership. NCEES does not say that any familiar classroom graphing calculator may be used; it lists the only acceptable calculator families for the 2026 exams. For Texas Instruments, that list is limited to TI-30X and TI-36X models. The stored calculator data identifies the TI-84 Plus CE as a rechargeable color graphing calculator, not as a TI-30X or TI-36X model. That means the device fails the name-family test even before considering graphing, programming, color screen, memory, or classroom popularity. This conclusion is model-specific and conservative: it does not ban every Texas Instruments calculator, and it does not depend on whether a proctor could clear memory or restrict apps. It follows the current NCEES allowed-family language and applies it to the exact printed model name.
