This article analyzes the perceptions of sexual affective diversity among teachers in Spanish high schools. Specifically, we address LGBTphobia, and teacher intervention and training through a survey study of 119 teachers. We administered a questionnaire to investigate these issues based on other studies. The data were analyzed on the basis of descriptive statistics. We attempted to answer three research questions: How do teachers analyze LGBTphobia in high schools? What is their experience and teaching intervention with regard to affective and sexual diversity? What perception exists in high schools about the need for training and education on affective and sexual diversity? The study concludes that high schools and their communities remain hostile places for LGBT students. Therefore, incorporating training into teaching practice and rethinking pedagogy from a queer perspective is fundamental to building an inclusive educational culture.
