To comprehend the evolution of education-service-community integration (ESCI) in the municipality of Bragança Paulista, SP, through the Teaching-Health Public Action Organizational Contract (Coapes), a case study was conducted. An intentional sample of ten members from the Local Management Committee participated in semi-structured interviews, conducted virtually, recorded, and transcribed in full. The narratives underwent thematic content analysis. The results indicated that the implementation of IESC and Coapes was successful. The sustainability and achievements in contractualization are related to strategies such as approaching, institutional dialogue, equal value, and transparency, resulting from technical discussions, understanding of the process, format selection, sensitization, and actor engagement. The combination of these elements, along with new projects and attitudes, points towards the consolidation of IESC in the territory, which presents challenges to be overcome.
