Medical assistant in Missouri: licence, certification and what employers require (2026)

Missouri does not license medical assistants; no state licence; employers ask for a national certificate (CMA from AAMA, RMA from AMT, CCMA from NHA). This page says what a medical assistant licensed or working in another state has to do to work in Missouri, in the order to do it, and what goes wrong when the order is reversed.

How the transfer works

No state licenses medical assistants, so there is nothing to transfer: your national certificate is valid in Missouri as it is. What changes is what Missouri lets a medical assistant do, especially around medication and injections, which is set by the state medical board and followed by employers.

What to have ready before you move

• Your national certificate and its renewal date
• Documentation of any skills ${STATE} regulates (injections, phlebotomy)

Start the paperwork before you give notice. There is no Missouri licence to wait for, so the only clock is the employer's.

What people get wrong

• Letting the national certificate lapse during the move; renewal needs continuing education
• Assuming scope of practice is the same; it is set per state
