Schools have a legal, ethical, and moral obligation to provide to all students equal access to education and equal protection under the law. For many sexual minority students, however, schools are unsafe and survival, not education, is the priority. Schools typically do not have the information, interest, or comfort level to address the needs of sexual minority students. However, school principals are responsible for all students, including sexual minorities. School personnel may be their only support system and, with effective intervention, can have a positive impact on lesbians, gays, bisexuals, and transgenders (LGBT) students. An affirmative environment is more likely when school personnel are knowledgeable about protective factors and the needs of sexual minority students, provide them with support and understanding, and become their advocates and allies. In this article, the author discusses several measures to avoid sexual discrimination against lesbians, gays, bisexuals, and transgenders in the school setting, which include improving school safety, providing a support network for sexual minority students, and training all staff to understand sexual minority students and use effective interventions.
