This report is the result of studies and learning on the Assessment, Diagnosis and Intervention in Institutional/Clinical Psychopedagogy internship, during which a psychopedagogical assessment of a child was carried out, taking into account the stages suggested by authors in the field. It should be noted that this psychopedagogical assessment took place with a five (5) year old male child, who initially complained of linguistic difficulties in reading and writing. Despite a lot of resistance still observed among those involved in the schooling process, such as the family and the school, mainly due to lack of knowledge, we can see that committed work ends up breaking down barriers and stereotypes that are still linked to school failure. In this sense, we highlight the importance of the role of the psychopedagogue as an important professional mediator of these relationships, whether in the school or clinical setting, exploiting all the potential that learners have.
