This article was written based on the results of the application of the evaluation research in the process of implementation of a health policy in a town in the State of Minas Gerais, Ponte Nova. For this purpose, we used the theoretical presuppositions of the process evaluation research. It was contextualized the policies applied to the public health field from the 1970s through two complementary axes: the Federal Constitution of 1988 and the Health Organic Laws, 8.080 and 8.142 from 1990, which create and regulate the Sistema Único de Saúde (SUS). In order to obtain the necessary information to the analysis, it is important to identify the indicators, which explain the several forms of participation of the members of all categories in the Council:/ government, health workers, professionals and users./ For/ this proposal, the minutes of the meetings of the Council were analysed from July 2003 to June 2005. Among the results obtained in the research, we can point out the forms of participation of the members of the Council, identified through indicators like clearances, proposals, suggestions, measures, questions, presentation of results, notices, complaints, deliberations, indictments and comments. Each of these indicators were analysed in relation to the categories represented in the Council: government, health workers, professionals and users. This analysis revealed the forms of participation of the counsillor in the meeetings, that is, the way each category acts in this democratic institution.
