Based on theoretically driven models, the Chicago School Readiness Project (CSRP) targeted low-income children’s school readiness through the mediating mechanism of self-regulation. The CSRP is a multicomponent, cluster-randomized efficacy trial implemented in 35 Head Start–funded classrooms (N = 602 children). The analyses confirm that the CSRP improved low-income children’s self-regulation skills (as indexed by attention/impulse control and executive function) from fall to spring of the Head Start year. Analyses also suggest significant benefits of CSRP for children’s preacademic skills, as measured by vocabulary, letter-naming, and math skills. Partial support was found for improvement in children’s self-regulation as a hypothesized mediator for children’s gains in academic readiness. Implications for programs and policies that support young children’s behavioral health and academic success are discussed.

The present study evaluated the efficacy of a multicomponent, classroom-based intervention in reducing preschoolers' behavior problems. The Chicago School Readiness Project model was implemented in 35 Head Start classrooms using a clustered-randomized controlled trial design. Results indicate significant treatment effects (ds = 0.53-0.89) for teacher-reported and independent observations of children's internalizing and externalizing behavior problems. Moreover, there was some evidence for the moderating role of child gender, race/ethnic group membership, and exposure to poverty-related risk, with stronger effects of intervention for some groups of children than for others. Findings contribute to a growing area of research on poverty and preventive intervention in early childhood.

We used longitudinal data from a birth cohort study, the Fragile Families and Child Wellbeing Study, to investigate the links between Head Start and school readiness in a large and diverse sample of urban children at age 5 (N = 2,803; 18 cities). We found that Head Start attendance was associated with enhanced cognitive ability and social competence and reduced attention problems but not reduced internalizing or externalizing behavior problems. These findings were robust to model specifications (including models with city-fixed effects and propensity-scoring matching). Furthermore, the effects of Head Start varied by the reference group. Head Start was associated with improved cognitive development when compared with parental care or other nonparental care, as well as improved social competence (compared with parental care) and reduced attention problems (compared with other nonparental care). In contrast, compared with attendance at prekindergarten or other center-based care, Head Start attendance was not associated with cognitive gains but with improved social competence and reduced attention and externalizing behavior problems (compared with attendance at other center-based care). These associations were not moderated by child gender or race/ethnicity. KeywordsHead Start; school readiness; urban children; propensity score matching Since its inception in 1965, Head Start has been the single largest publicly financed early childhood education and care program in the United States. Head Start's primary goal is to improve the school readiness of children from low-income families by delivering highquality and comprehensive early education services to preschool age children, in particular, 3-and 4-year-olds. However, throughout its history, the success of the program in meeting this goal has been debated

Since its inception 15 years ago, the Minimum Living Standard Assistance (MLSA) has served as a last resort for China's urban poor. Using national household survey data, this study provides updated evidence on the participation rate, receipt amount, and anti-poverty effectiveness of MLSA. Families eligible for MLSA make up 2.3 percent of the urban population, but only about half of them are actual beneficiaries. City MLSA generosity and household entitled benefit amount both positively correlate with participation rate and household receipt amount. MLSA lowers the poverty rate somewhat, but substantially reduces the poverty gap and severity for its eligible participants. Nevertheless, the poverty reduction role of MLSA is restricted by its partial coverage and delivery. Consequentially, poverty remains a serious problem for MLSA's target population. The anti-poverty effectiveness of MLSA can be strengthened by full coverage and delivery of benefits and by paying special attention to disadvantaged subgroups.

Using data from the Early Childhood Longitudinal Study-Birth Cohort (n ≈ 6,950), a nationally representative sample of children born in 2001, we examined school readiness (academic skills and socio-emotional wellbeing) at kindergarten entry for children who attended Head Start compared to those who experienced other types of child care (prekindergarten, other center-based care, other non-parental care, or parental care). Using propensity score matching methods and OLS regressions with rich controls, we found that Head Start participants had higher early reading and math scores than children in other non-parental care or parental care, but also higher levels of conduct problems than those in parental care. Head Start participants had lower early reading scores compared to children in prekindergarten, and had no differences in any outcomes compared to children in other center-based care. Head Start benefits were more pronounced for children who had low initial cognitive ability or low-educated parents, or attended Head Start for more than 20 hours per week.
