In the last twenty years, we had significant transformations in Brazilian society with the advancement of lesbian, gay, bisexual, transvestite, and transgender men and women (LGBT), resulting in the emergence of a pro-LGBT public policy agenda driven by a strong network of civil society organizations - professional associations, political parties, social movements, academic entities, etc. In this poster, we will present an analysis of LGBT policies implemented by the Federal Council of Psychology [Conselho Federal de Psicologia], the main psychology institution in Brazil, and a public authority with the power to regulate and supervise professional practice . We will focus on the period from 1999 to 2018, from the presentation of Resolution nº 1 of 1999, which "establishes norms of action for psychologists in relation to the issue of sexual orientation" to the present day. As a methodological procedure, an extensive bibliographical and documentary review was carried out, with the survey of primary sources of research, such as management reports, minutes of assemblies and congresses, public positions, news and oficial publications. With the publication of Resolution 01/99, the Federal Council of Psychology prohibited the pathologization of homosexuality and the "sexual conversion" therapies offered by psychologists, being a pioneering action within the field of professional health autarchies in Brazil. Among the most relevant policies are: the defense of the right of homosexual couples to adoption, the fight against the repatologization of homosexuality, the recognition of the social name of the trans people, and the proposition of depathologization of transvestite and transsexual identities.
