Adds new Article 43, Behavior Analyst Licensure, to GS Chapter 90. Prohibits a person from practicing as a licensed behavior analyst or an assistant behavior analyst without a state license issued pursuant to the Article, with specified exemptions. Defines behavior analysis as the design, implementation, and evaluation of systematic instructional and environmental modifications to produce significant personal or interpersonal improvements in human behavior. Effective January 1, 2022, makes violations of the Article a Class 2 misdemeanor. Establishes the NC Behavior Analysis Board (Board), with five members (three appointed by the Governor and one each upon recommendation of the Speaker of the House of Representatives and the President Pro Tem. of the Senate). Charges the Board with administration of the licensing program and requires the Board to make an annual report to the Governor. Sets out qualifications for licensure as a behavior analyst or assistant behavior analyst, fees that may be charged by the Board, and the Board’s disciplinary authority. Allows for reciprocity and for the the issuance of temporary licenses. Permits criminal record checks for licensees and persons seeking licenses. Makes conforming changes to GS 90-270.138. Requires the Board to adopt temporary rules to implement the act, which remain in effect until permanent rules are in effective. Enacts GS 8-53.14 governing the confidentiality of communications between a behavior analyst and their client or patient.
