Applied behavior analysis; transferring licensure powers and duties to the State Board of Examiners of Psychologists; requiring background check. Effective date.
SB 1557 transfers the licensing authority for behavior analysts from Oklahoma's Department of Human Services to the State Board of Osteopathic Examiners. The bill requires all applicants to undergo a national criminal history background check and updates definitions to clarify that only professionals certified by the national Behavior Analyst Certification Board (and licensed by the State Board) may practice applied behavior analysis. It also specifies that supervisees must work under a licensed behavior analyst and maintains requirements for renewal and professional conduct standards. This changes who oversees licensure, adds background checks, and standardizes practice rules for behavior analysts.

MODERATE
The bill was transitioned from the House version to the Senate floor version, incorporating specific formatting updates and committee amendments. The substantive policy content, including definitions, licensing requirements, and the transfer of authority from the Department of Human Services to the State Board of Examiners of Psychologists, remains consistent between the two versions.
TECHNICAL
The document header was updated to reflect the Senate floor version with a new date (February 16, 2026) and a revised title block.
Page numbering and footer text were updated to indicate the Senate floor version instead of the House floor version.
The explanatory text at the top of the document was reorganized to clarify that bold face text denotes committee amendments.
Minor spacing and indentation adjustments were made throughout the text to align with Senate formatting standards.
