Even though the political agenda makes explicit the importance of generating processes for attention to diversity and the inclusion of the LGBTIQ community in the university community, there are few models of teacher training aimed at university professors as one of the main ones responsible for developing practices educational institutions that fight against exclusion and discrimination. For this reason, in the first place, an investigation of the training offered on LGBTIQ diversity in the teacher training programs of Spanish universities is carried out in which the incipient state of institutionalization of this as a strategic line is evidenced. Next, a teacher training model is proposed based on evidence from scientific literature. Finally, faced with the traditional dissemination of scientific knowledge in educational sciences, this chapter proposes as a novelty a training model that can influence and be transferable to university policy and practice.
