GLSEN (the Gay, Lesbian, and Straight Education Network) was created in 1990 to promote LGBT issues in kindergarten, elementary, middle, and high schools. It supports students and teachers. GLSEN is best known for helping schools form and sustain Gay-Straight Alliance (GSA) clubs. Some administrations and parents are so vehemently hateful against GSAs that they have ended all after-school clubs at their schools rather than allow for the GSAs to operate. GLSEN sponsors the Day of Silence each year.
