Over 20 years, GLSEN’s research has demonstrated that LGBTQI+ inclusive instruction promotes a more positive school climate, where LGBTQI+ youth are more likely to thrive academically, socially, and emotionally, and experience less severe anti-LGBTQI+ harassment and bullying. This issue brief demonstrates that the benefits of LGBTQI+ inclusive learning extend beyond the classroom to school libraries, instructional materials, and school laptops or media centers (and other means of accessing school internet). We have intentionally moved to consider inclusive learning broadly here to illuminate a fuller range of sites and resources in K-12 schools that support student learning, including that which is student-driven. At the time of publication, each of these sites and resources is under attack by those opposed to inclusive learning.
