This article describes the Model Standards Project (MSP), a collaboration of Legal Services for Children and the National Center for Lesbian Rights. The MSP developed a set of model professional standards governing the care of lesbian, gay, bisexual and transgender (LGBT) youth in out-of-home care. This article provides an overview of the experiences of LGBT youth in state custody, drawing from existing research, as well as the actual experiences of youth who participated in the project or spoke with project staff. It will describe existing professional standards applicable to child welfare and juvenile justice systems, and the need for standards specifically focused on serving LGBT youth. The article concludes with recommendations for implementation of the standards in local jurisdictions.
