Previous publications on school experiences of lesbian, gay, bisexual, and questioning/queer (LGBQ or sexual minority) students have focused mostly on Australian, European and American schools. Very few publications have examined sexual minority students’ experiences in East Asian countries, especially in Chinese and Korean societies, where sexual minority equality has been a subject of long-term debate for years, and prejudice towards this invisible population persists without legal protection. Studies in both Hong Kong and Korea have found that educators do not have sufficient training to support their work with sexual minority students. Based on the literature on sexual prejudice and school experience of LGBQ students, this chapter summarizes research studies on LGBQ students in two East Asian societies – Hong Kong and South Korea –to understand their experiences in facing sexual prejudices. Findings from this study will inform school supports and practice related to inclusion of LGBQ students in the Asian context.
