GLSEN's National School Climate Survey is the only national survey to document the experiences of students who identify as lesbian, gay, bisexual and transgender (LGBT) in America's secondary schools. Conducted biennially since 1999, the National School Climate Survey (NSCS) fills a crucial void in our collective understanding of the contemporary high school experience. The results of this survey are intended to inform educators, policymakers and the public at large, as part of GLSEN's ongoing effort to ensure that all schools are places where students are free to learn, regardless of sexual orientation or gender identity/expression. This year's survey includes responses from 1,732 LGBT students between the ages of 13 and 20 from all 50 states and the District of Columbia. Data collection was conducted through community based groups and service organizations, from April to July 2005, and online from April to August 2005. The 2005 NSCS results continue to track the endemic problem of name-calling, harassment and violence directed at LGBT students, while offering information about the impact of these experiences on academic performance and the effect of interventions designed to address the underlying problem. In particular, the 2005 survey data allowed us to examine the role that state education legislation has in creating (or not creating) safer schools for all students, including LGBT students. The 2005 NSCS paints a disturbing picture of the school experiences of LGBT students. However, it also provides further insight into the solutions for creating safer schools for all students.
