The study was designed to ascertain teachers’ perceptions of bullying of lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth. In a sample of 200 educators (61.0% female; 96.5% white) from a county in southwestern Pennsylvania, there was a significant positive relationship between the teachers’ perceptions of the supportiveness of school staff towards students regardless of sexual orientation and those teachers’ reports of the frequency of bullying victimization experienced by LGBTQ students. Teachers’ perceptions of a higher level of staff and student support was associated with higher reported frequencies of students’ use of derogatory language about LGBTQ individuals and various types of bullying of LGBTQ students. Teachers with a lesbian, gay, or bisexual orientation were found to rate the school staff and students as significantly less supportive of students regardless of their sexual orientation, gender identity, or gender expression in comparison to heterosexual teachers. Finally, teachers who were either unaware of their school having an anti-bullying policy or believed that their school lacked such a policy reported significantly higher rates of physical bullying of LGBTQ students when compared to the rates observed by teachers who reported knowledge of their schools’ anti-bullying policies.
