Health Education Unit News – CNA Renewals

Missouri currently has 975 CNA’s that have not renewed as of June 1, 2024.

Please check the registry for your status at MO TMU.

All CNAs are required to renew their certification every 24 months. Each renewal requires 8 hours of nursing services to be provided for every 24-month period. Proof of the nursing service can include a W2 or paystub from your employer.

All renewals are now electronic through our online registry (TMU) and a $20.00 fee is required.

If you have never logged into TMU Registry to setup your profile, then you will first need to contact the Health Education Unit at 573-526-5686 or for assistance. After your profile is setup, a text message and email will be sent to you 60 days prior to your inactive date, during your renewal period. This notification will prevent any delay in keeping your certification active.

If you already have setup your profile, then please see the renewal instructions at
