This thesis is a research in Social Psychology in which we intend to problematize in a broad way the issue of Agricultural Education in boarding school in Brazil. We seek to study its effects in terms of production of subjectivity, as well as to map its impasses and also to verify its current possibilities. Our approach is based on Critical Social Psychology theorists called Socio-Historical Psychology, basing this research on the concept of subjectivity, considering that the constitution of the subject is an eminently social process, encompassing its dialectical, social, collective and institutional totality. Our field of research includes an educational establishment that operates as a boarding school and houses a total of 175 adolescent inmates aged between 13 and 19 years who, during a period of three years, take the Agricultural Technician course compatible with Secondary Education.
