Research Findings: Using longitudinal survey data from the Welfare, Children, and Families Study: A Three-City Study ("n" = 135), this study examines how congruence in maternal and child care provider sensitivities contributes to young children's social, emotional, and academic outcomes among low-income minority families. Congruence groups were created based on levels of high and low maternal and child care provider sensitivity. Children with high maternal sensitivity and low child care provider sensitivity had lower scores on measures of social competence and applied problems compared to children with high maternal and child care provider sensitivity. Children with low maternal sensitivity but high child care provider sensitivity displayed higher emotional competence than children with low maternal and child care sensitivity, implying an important protective benefit of child care. Practice or Policy: Current state and federal policy climates, including recently awarded Early Learning Challenge grants focused on social and personal development and the Academic, Social, and Emotional Learning Act, reflect an important emphasis on social and emotional learning. Given this, the findings from this study implicate the role of families and child care providers as important components in any policy or program focused on shaping children's early social and emotional outcomes.
