The study of Educational Psychology is an important part of teacher professionalization, even though it is not considered as part of teacher training. Therefore, we investigate the influence of the discipline on teacher training and the expectations and perceptions of the graduates. The participants of our research were 159 graduates and PIBID scholarship students from a public university in Minas Gerais. We also had the participation of four students – former participants of the PIBID – from the university, as well as seven professors of Educational Psychology from the same university, and we conducted a quantitative-qualitative research. Our methodology included questionnaires, a conversation with some alumni students, and a study of the curricular documents of the university. Regarding the documents, the data revealed limited allocation time for Educational Psychology in most teacher training courses. Also, its role in the curricular structure seemed to obliterate a stronger articulation with other courses, especially those that deal with teacher training. The participating professors affirmed that the role assigned to the discipline was to train teachers, with special attention to the processes of human development and learning, and they showed concern with articulating the contents taught, having as a parameter the age group with which their students would work in the future. The teaching practices seemed to prioritize some theories and teaching techniques, based on the needs of students and their expectations regarding the subject. We verified the presence of a high percentage of traditional techniques/methods used, and, for the teachers, the contents were approached in a satisfactory way. We saw that undergraduate teaching students, upon their training courses, had positive expectations regarding the discipline of Educational Psychology, wished to take it, as well as believed it to be essential for their education. They manifested positive perceptions in relation to the Educational Psychology classes, considering them a positive addition to their coursework, and ways of eliciting good memories of the practices elaborated by their professors in the classroom, even while at the same time perceiving the techniques used as conservative and traditional. Participants identified a dialogue between the discipline of Educational Psychology and other areas, specific to their degree, and were categorical in saying that the discipline complements the others. However, they showed dissatisfaction in relation to the means by which dialogue takes place, attributing it to a lack of dialogue between theory and practice, because only half of them claimed to feel prepared to deal with the reality of everyday school life.
