Founded as a local group in 1990, the Gay and Lesbian Independent School Teachers Network (GLSTN) began as a volunteer group of 70 gay and lesbian educators. At that time, there were two Gay-Straight Alliances (GSAs) in the nation, only one state with policy in place to protect lesbian, gay, bisexual and transgender (LGBT) students, and a general lack of awareness of the needs of LGBT students. LGBT youth did not have a voice in the education community or in the LGBT movement. There were few, if any, resources available for teachers to discuss LGBT issues. Currently, GLSEN has registered more than 4,000 GSAs, has approximately 40 full time staff, a governing board of 20 members and two advisory committees at the national level. Since homophobia and heterosexism undermine a healthy school climate, we work to educate teachers, students and the public at large about the damaging effects these forces have on youth and adults alike.
