School attachment is often regarded as a key measure in gauging the integration and wellbeing of students. Previous research suggests that levels of school attachment are generally lower among sexual minority students, but most studies focus on between-gender comparisons and do not conduct within-gender analyses. Using data from the First National Climate Survey on Homophobia and Transphobia in Canadian schools, this study set out to empirically analyze what, if any, differences exist among lesbian, bisexual, and heterosexual female students when assessing the relationship between homophobic and gender-negative language, feelings of safety, harassment/direct victimization, and school climate on school attachment. Bivariate and multivariate findings suggest that there are key differences among female students in terms of school attachment.
