A. The confidential relations and communications between a client and a person who is licensed pursuant to this article, including temporary licensees, are placed on the same basis as those provided by law between an attorney and client. Unless the client waives the behavior analyst-client privilege in writing or in court testimony, a behavior analyst shall not voluntarily or involuntarily divulge information that is received by reason of the confidential nature of the behavior analyst’s practice. The behavior analyst shall divulge to the board information it requires in connection with any investigation, public hearing or other proceeding. The behavior analyst-client privilege does not extend to cases in which the behavior analyst has a duty to report information as required by law.

B. The behavior analyst shall ensure that client records and communications are treated by clerical and paraprofessional staff at the same level of confidentiality and privilege required of the behavior analyst.
