Decades' worth of studies point to the importance of parental involvement in K-12 schooling. Yet when it comes to policies related to lesbian, gay, bisexual, and transgender (LGBT) students, families are often deliberately left out of the conversation, according to several leading experts in LGBT youth development. Even in schools where LGBT-positive programs such as gay-straight alliances exist, they are often kept low key. Obviously, educators need to exercise care when discussing LGBT students--some may not be "out" to family members, or some parents and caregivers may not be supportive of their children's LGBT identities. But in some cases, they say, family involvement is absent, or even avoided, for fear of controversy. This article discusses why family support is critical to LGBT student success as shown by research.
