"The 2013 National School Climate Survey" is GLSEN's 8th biennial report on the school experiences of LGBT youth in schools, including the in-school resources that support LGBT students' well-being, the extent of the challenges that they face at school, and insights into many other aspects of LGBT students' experiences. The survey has consistently indicated that a safer school climate directly relates to the availability of LGBT school-based resources and support, including Gay-Straight Alliances, inclusive curriculum, supportive school staff, and comprehensive anti-bullying policies. The full 2013 "National School Climate Survey" report includes information LGBT middle and high school students' experiences with: (1) hearing biased language; (2) experiences of harassment and assault; (3) anti-LGBT discrimination at school; and (4) the availability and impact of supportive school resources. The authors also examine: (1) the possible negative effects of a hostile school climate on LGBT students' academic achievement, educational aspirations, and psychological well-being; (2) whether or not students report experiences of victimization to school officials or to family members and how these adults address the problem; and (3) how the school experiences of LGBT students differ by personal and community characteristics.
