GLSEN (pronounced "glisten") was founded in 1990 by a small, but dedicated group of teachers in Massachusetts who came together to improve an education system that too frequently allows its lesbian, gay, bisexual, transgender, queer and questioning (LGBTQ) students to be bullied, discriminated against, or fall through the cracks.  Over 25 years later, that small group has grown into the leading national education organization focused on ensuring safe and affirming schools for LGBTQ students. -conduct extensive and original research to inform our evidence-based solutions for K-12 education. -author developmentally appropriate resources for educators to use throughout their school community. -partner with decision makers to ensure that comprehensive and inclusive safe schools policies are considered, passed and implemented. -partner with dozens of national education organizations to leverage our shared expertise into creating great schools and better opportunities for every student.  -empower students to affect change by supporting student-led efforts to positively impact their own schools and local communities.
