The Gender & Sexuality Alliance (GSA) is a student-led and student-organized school club that aims to create a safe, welcoming, and accepting school environment for all youth, regardless of sexual orientation or gender identity.

GSAs provide a supportive environment for lesbian, gay, bisexual, transgender, and queer (LGBTQ) students, as well as those who are perceived by others to be LGBT, are questioning their identity, have LGBT friends or family members, or just care about LGBT issues.
