After counseling with the bishopric, Melchizedek Priesthood leaders call members of their quorums or group to serve as home teachers. This call is issued in a private interview.
Teachers and priests of the Aaronic Priesthood are called as home teachers (junior companions). The bishopric issues home teaching calls to Aaronic Priesthood brethren. . . .Regular reporting on activation efforts is part of home teaching interviews at every level. . . .
Home teachers should make appointments for their visits at a time convenient for the individual or family. Home teachers should remember they are guests of the members they visit.
