Positive school climates foster an optimal learning environment in which students feel safe and supported, and are in a greater position to thrive in terms of academic performance, better relationships with peers and staff, and overall social-emotional well-being. Lesbian, gay, bisexual, transgender, or queer (LGBTQ) students often have to navigate more challenges and hostile school climates compared to their heterosexual peers because school practices, policies, and curricula tend to prioritize heteronormative structures. Significant work is required to challenge these structures, such as by implementing zero-tolerance policies, LGTBQ-inclusive curricula and mandatory professional development for educators, and by creating safe spaces for LGTBQ students within schools.
