Market context

Missouri occupational therapy roles stay competitive

In Missouri, allied health employers often look for occupational therapy candidates who can start with full licensure and NBOTC registration, so demand tends to favor applicants who are already credentialed. These roles are competitive because clinics, schools, and rehab settings want candidates with an ACOTE-accredited degree, an unencumbered state license, and readiness to work across patient needs. Review the AI-summarized requirements and benefits here to save time, then confirm your license status and registration before applying.
