About the Missouri CNA, CMT and Insulin Registry
The Missouri CNA, CMT and Insulin Registry is the official database of Certified Nurse Assistants, Certified Medication Technicians, and Insulin Administration certified workers in Missouri. It is maintained by the Department of Health and Senior Services (DHSS) Section for Long Term Care Regulation, with registry data managed by D&SDT-Headmaster through the TMU (Test Master Universe) portal at mo.tmutest.com.
Employers in Missouri are required by 19 CSR 30-84 to verify the registry status of every CNA before allowing them to provide direct resident care. The registry reflects active certification, renewal status, any reciprocity transfers, and substantiated findings of abuse, neglect, or misappropriation of resident property, with disciplinary findings remaining permanently visible per federal OBRA rules.
Public registry searches are available 24/7 at mo.tmutest.com/search, where anyone can verify a Missouri CNA's status by name or certificate number. DHSS staff handle phone verification, reciprocity questions, and disciplinary inquiries Monday through Friday between 9:00 a.m. and 3:30 p.m. Central Time at (573) 526-5686.

Frequently Asked Questions
How do I verify a Missouri CNA's license online?
Use the public TMU search at mo.tmutest.com/search. Enter the CNA's first and last name, or their certificate number, and the search returns current registry status (active, expired, or with findings), certificate number, expiration date, and any reciprocity history. The verification is free and updates in real time as D&SDT-Headmaster processes new certifications and renewals on behalf of DHSS.
How often must Missouri CNAs renew?
Every 24 months. To renew, the CNA must document at least 8 hours of paid nursing or nursing-related services within the prior 24 months by submitting paystubs, a W-2, or a signed employer letter through the TMU portal. There is a small renewal fee paid online during the submission process. Renewals can be filed up to 60 days before expiration.
Does Missouri offer free CNA reciprocity from other states?
Yes. Missouri offers free reciprocity to CNAs in good standing on another state's nurse aide registry. You apply through TMU, submit a copy of your out-of-state certificate, proof of identity, and verification of at least 8 hours of paid nursing-related work in the prior 24 months. DHSS typically processes the request within 7-10 business days, and Alabama applicants must additionally show the 8-hour work proof on the Alabama side.
What can disqualify someone from the Missouri CNA Registry?
Under 19 CSR 30-84 and the federal Employee Disqualification List (EDL), CNAs may be disqualified for substantiated findings of resident abuse, neglect, or misappropriation of property, as well as certain felony convictions identified by the Family Care Safety Registry (FCSR). DHSS posts substantiated findings permanently on the public registry, and disqualified individuals are placed on the EDL, which Missouri employers are required to check before hiring.
How do I contact the Missouri CNA Registry office?
You can reach the Missouri DHSS CNA Registry at (573) 526-5686 or by email at [email protected]. The call center is open Monday through Friday from 9:00 a.m. to 3:30 p.m. Central Time. Mail correspondence goes to Health Education Unit - CNA Registry, PO Box 570, Jefferson City, MO 65102. Headmaster exam-related questions go to (888) 401-0462.
Can employers verify multi-state registry status from Missouri?
Yes, and Missouri DHSS requires employers to do so. Federal OBRA rules require facilities to check every state registry that may have information on a prospective CNA before hire. The Missouri TMU search returns Missouri status only - to check other state registries, employers must search each state's registry separately, or use a multi-state lookup service such as the Credentia or Nursys cross-state tools.
