The written exam is the final step to placement on the Idaho State Registry for nurse aides. Candidates must first pass the CNA skills exam before taking the written exam. Written exams may be scheduled in advance. Exam times are available on Wednesdays 10 am-4 pm, Thursdays 12-6 pm and Fridays from 9 am-1 pm. Tests are conducted in the Workforce Training Center computer lab (no computer skills required, just point and click). If an oral exam is needed, ADA documentation is required. Once you successfully pass your exam, you will be placed on the registry within 48 hours.
