Many scholars have defined family life education (FLE), and some have differentiated it from other family-related fields. For example, Doherty (1995) provided a definition of the boundaries between FLE and family therapy; however, we believe those criteria can be improved. We explore the professions of family life education, family therapy, and family case management using the questions why, what, when, for whom, and how? After examining these questions for each role, we introduce the domains of family practice to differentiate among them. The approach defines FLE and encourages appropriate collaboration among the fields. Suggestions are made for using this model for career exploration, reviewing job requirements to assess role consistency and clarity, and for determining the need for and appropriateness of referral and collaboration.
