This chapter is mainly focused on what is happening, in universities, with the teaching of gender to pre-service teachers, specifically transgender issues. Universities are hyper-regulated institutions which seem to practice an invisible censorship when it comes to the pursuit of knowledge and the choice of topics for teaching and research. The education of pre-service teachers in Colombia does not take gender diversity and especially transgender persons into account. This monolithic idea of what “The English teacher” is supposed to be is an evident problem in the education of teachers, a field which is “de-gendered”, in that it not only denies the existence of “genders” in the classroom but transgender “individuals” as well. This chapter discusses attitudes towards transgenderism in teaching, specifically in the education of pre-service teachers and draws on some previous studies of ELT teachers’ and students’ perceptions of transgenderism. It also looks at aspects of the experiences of transgender teachers and students which have been ignored in previous studies and may throw light on how to deal with transphobia and strengthen the identity of pre-service transgender teachers.
