This study aimed to verify the adequacy of family health teams according to the quality standards set by the Brazilian Ministry of Health and the correlation with health care activities, according to the health professionals themselves. The Evaluation for Quality Improvement (EQI) instrument was used in joint interviews with physicians, nurses, and dentists. Scores were defined for each of the dimensions, according to the number of standards met under the EQI. The lowest scores on the "consolidation of the model" dimension were for community participation and social control. For health care, the lowest scores were for adolescents' health. The sub-dimensions "reception and humanization" and "health promotion" were statistically associated with child, adult, and elderly health care. The sub-dimension "work organization" was statistically associated with child and elderly health care. A positive correlation thus exists between the model's consolidation and quality improvement.
