CWLA Best Practice Guidelines – During the past decade, lesbian, gay, bisexual, and transgender (LGBT) adolescents have become increasingly visible in our families, communities, and systems of care. A significant number of these youth are in the custody of child welfare or juvenile justice agencies. Yet the public systems that are charged with their care and well-being have been unresponsive to their needs and slow to acknowledge that LGBT children and adolescents are in urgent need of appropriate and equitable care (see, for example, Mallon, 1992, 1994, 1998). Child welfare and juvenile justice systems have not incorporated advances in research and understanding related to human sexuality and child and adolescent development that have informed the development of professional standards and guidelines for the major professional associations. As a result, these systems continue to deliver misguided, uninformed, second-class care to LGBT youth in their custody.
