Over half of the toddlers in the U.S. experience routine nonparental care, but much less is known about early care than about preschool care. This study analyzed 2-year-old child care and child outcome data from the nationally representative ECLS-B sample of children born in 2001. At two-years of age, 51% of children experienced exclusive parental care, 18% relative care, 15% family child care, and 16% center care. More children in nonparental care were in medium quality care (61%) than in high quality (26%) or low quality (13%) care. Low-income children were more likely than non-low income children to be cared for by their parents and, when in care, were more often in lower quality care. The impact of toddler care quality on cognitive skills was estimated using propensity score adjustments to account for potential selection confounds due to family and child characteristics. Children's cognitive scores were higher in high or medium quality care than in low quality care, but no evidence emerged suggesting that poverty moderated the quality effects. Nevertheless, this suggests that increasing the proportion of low-income children in high quality care could reduce the achievement gap because low-income children are very unlikely to experience high quality care.

Value-added (VA) models measure teacher contributions to student learning and are increasingly employed in educational reform efforts. Using data from 35 seventh-grade teachers and 2,026 students across seven schools, we employ VA methods to measure teacher contributions to students’ motivational orientations (mastery and performance achievement goals) and their mathematics performance. The analysis suggests less variation in teachers’ contributions to students’ achievement goals than mathematics achievement. However, during a time when most students’ mastery motivation is declining sharply, a one standard deviation increase in teacher contributions to student mastery orientation is associated with a 40% smaller decline in student mastery goals. Teacher mastery contributions are also associated with gains in a student’s seventh-grade mathematics achievement (d =.11). In addition to using VA measures to focus on improving student achievement, these measures can be used to orient teachers, schools, and districts on the enhancement of students’ motivation to learn.
