If an individual delivers a service under Section 546.0104(2)(B)(ii), the legally authorized representative must be present when the service is performed or be immediately accessible to the individual who delivers the service. If the individual will perform the service when the representative is not present, the representative must observe the individual performing the service at least once to assure the representative that the individual can competently perform that service. (Gov. Code, Sec. 531.051(f).)
