CNA Certification Status & Renewals

The DHSS Health Education Unit encourages you to check the certification status of your CNA staff. CNA’s are required to renew their certification every 24 months to remain “active” on the registry.

Please see the link to login: MO TMU (

Please note: If a CNA has never logged into the TMU registry, they will need to call HEU at 573-526-5686 the first time for assistance.

HEU is very excited to announce a new option for CNA Renewals coming soon!!! This new feature will allow employers to verify employment and pay for multiple CNA staff electronically. Please stay tuned for the official announcement and details.
