THE EXPERIENCES OF LESBIAN, GAY, BISEXUAL AND TRANSGENDER MIDDLE SCHOOL STUDENTS

This "research brief" from GLSEN (Gay, Lesbian, and Straight Education Network) is an excellent resource for statistics about bullying and other difficulties in American middle schools (junior high). Some of the report focuses on the availability of in-school LGBTQ+ resources, and works to compare some situations to the statistics from high schools on the same issues. 

Length: Short (under 25 pages).
