[U4Q] Hаrmоny hаs been wоrking with а client fоr almost five years. She conducted the initial assessment for the client and had the parents sign a parent handbook at that time. The parent handbook included all relevant information about services, BACB requirements, licensure requirements, and additional policies. Since the initial assessment, BACB and licensure requirements have changed. Harmony has verbally discussed these changes with the parents but has not provided them with an updated parent handbook to sign. Which ethics standard is being violated in this scenario?
