Page 7 of the NCEES Examinee Guide states, "You are allowed to bring one NCEES-approved calculator into the testing room." It is safe to assume they mean a calculator the examinee possesses, including taking it to the test facility and removing it from the test facility. Exam centers that do not allow this would be violating the NCEES exam policy. They do provide a Texas Instruments TI-30XS MultiView Scientific Calculator emulator on the computer as a backup, but its exclusive use is not mandatory. Any test center that violates the NCEES policy should be reported to the NCEES.
