In this study, we found a positive relationship between maternal education and the environmental quality of day care centers attended by children; it was shown that mothers with higher education choose higher quality day care for their children. Similarly, Sylva et al.14 reported that mothers with higher levels of education choose school environments that are richer in stimuli for child development, as they understand the day care center as an important environment for development, and not just a child-care place during their working time. Regarding the socioeconomic factor, there was no correlation with the child's performance, although it is a risk factor well described in the literature.8 , 11 , 28 It is believed that this lack of correlation is due to the small amount of children in socioeconomic class A. This prevented the representation of higher class children in this study.
