Expedited recognition — nonresident military or law enforcement spouse
No examination is required for this applicant pathway.
Compact limits
A license issued under this section is valid only in Missouri. Applicants licensed in another state pursuant to an interstate compact are ineligible under subsection 11.
Eligibility
Hold a valid current license at the same practice level issued by another state, a military branch/unit, a United States territory, or the District of Columbia; show at least one year of licensure in that jurisdiction.
Fees and other requirements
Fees, bonds/surety bonds and proof of insurance are not waived; the Department retains statutory grounds for denial and fingerprint authority.
Good standing
Satisfy RSMo 324.009.4: current good standing, no revoked license, no pending investigation/complaint or unresolved disciplinary matter, and no criminal record that disqualifies licensure. Corrected and resolved discipline is considered under subsection 4(2).
Lower ranked exam demand
The DHSS FAQ, under “Will the Missouri Lead Licensing program approve a license through reciprocity?”, states: “Applicants applying to become a licensed Risk Assessor, Lead Inspector, or Lead Abatement Supervisor in the State of Missouri through reciprocity are required to take the state exam administered by the Lead Licensing Program. A score of 70% or better is required.” This implementation demand is preserved for the applicant; the qualifying statutory waiver controls this route.
Program implementation
The current DHSS Reciprocity page accepts current out-of-state licensure as evidence of education, training, and experience under RSMo 324.009. This corroborates the statute; the statute effective August 28, 2026 is the controlling evaluation-date evidence.
Spouse status
Meet the nonresident military or law enforcement spouse definition in RSMo 324.009.1(4): qualifying spouse transfer, permanent-change-of-station move, or qualifying accepted Missouri law-enforcement employment.
Statutory exclusions
RSMo 324.009.12 excludes the occupations exhaustively listed in RSMo 290.257.6 and electrical contractors under 324.900–324.945; the obtained list does not name lead inspectors.
Verification
The other jurisdiction must verify the minimum education and any applicable experience and clinical supervision requirements and that the applicant met them.
Waiver
RSMo 324.009.3(2) requires waiver of examination, educational, and experience requirements and issuance within 30 days for an otherwise qualifying spouse. The law-examination reservation in subdivision (1) is not stated in subdivision (2).
