Changing the Game: The GLSEN Sports Project – “Changing the Game: The GLSEN Sports Project’s mission is to assist K-12 schools in creating and maintaining an athletic and physical education climate that is based on the core principles of respect, safety and equal access for all, regardless of sexual orientation or gender identity/expression. The GLSEN Sports Project fills a critical gap and adds a vital new dimension to GLSEN’s work to create a world in which every child learns to accept and respect all people, regardless of sexual orientation or gender identity/expression.”
