Frequency of interaction, or how much time lapses in between, is to be determined based on the selected program model or evidence-based, home-visiting model. Meetings/visits with client should be based on the client's needs and occur consistently. The duration of client meetings/visits (e.g., one (1) hour) should be sufficient to address client needs, follow any program model guidance or policies, and be flexible enough to accommodate the client's work schedule/life circumstances.
