The current study has the objective of understanding how the supervision of the field work is being carried out in the eyes of the supervisors that collaborate in the professional development of the students of the Social Work Department of PUC-Rio. As such, a quanti-qualitative study was undertaken which included a mapping of the field placements and their respective supervisors, the application of a questionnaire via e-mail or personally to all social workers whom made up the team of supervisors of the Department in the second semester of 2008, a semistructured interview with eight supervisors from the field and one interview with the professor responsible for the Coordination of Field Placement at the Department. The interviews were recorded with the permission of the interviewees, transcribed and analyzed in light of the central categories of the study: professional development, field work and supervision. The results indicates a necessity of formative preparation to exercise the supervision of the students, as even these days there are many obstacles and difficulties which permeate this activity, indicating that it will become the priority in the professional development of the social work, beginning with the communications between all involved in this process, as well as the necessity of a better approach among the educational institution, the field work institutions and the supervisors.
