How do I transfer my out-of-state CNA certification to Missouri?
If you are currently active on another state’s register, Missouri will allow you to challenge the Missouri CNA exam to become registered as a CNA in Missouri. Submit a copy of the out-of-state certificate, copy of social security card, return address, daytime phone number, and work verification of 8-hours in every two years from certification unless the out-of-state registry tracks your employment. (Federal regulation 483.154)
