High-quality preschool programs are heralded as effective policy solutions to promote low-income children’s development and life-long wellbeing. Yet evaluations of recent preschool programs produce puzzling findings, including negative impacts, and divergent, weaker results than demonstration programs implemented in the 1960s and 70s. We provide potential explanations for why modern preschool programs have become less effective, focusing on changes in instructional practices and counterfactual conditions. We also address popular theories that likely do not explain weakening program effectiveness, such as lower preschool quality and low-quality subsequent environments. The field must take seriously the smaller positive, null, and negative impacts from modern programs and strive to understand why effects differ and how to improve program effectiveness through rigorous, longitudinal research.
Prior research has found that financial investments in North Carolina’s pre-kindergarten (pre-K) program generated positive effects on student reading and math achievement through eighth grade (Bai et al., 2020). The current study examined the interaction between NC Pre-K funding and two key dimensions of the subsequent educational environment students experience in their school districts: average achievement and achievement growth. In relation to student reading and math achievement in eighth grade, the benefits of NC Pre-K funding were found to be additive to the benefits of school-district average achievement. The benefits of NC Pre-K funding were also found to interact with the benefits of school-district achievement growth such that the NC Pre-K effect was larger in school districts with lower rates of growth in academic achievement. These findings suggest that public investments in early childhood education may be particularly beneficial in the long term for children who subsequently experience low-growth schooling environments compared to children in high-growth environments.
COVID-19 has created acute challenges for the child care sector, potentially leading to a shortage of supply and a shrinking sector as the economy recovers. This study provides the first comprehensive, census-level evaluation of the medium-term impacts of COVID-19 on the county child care market in a large and diverse state, North Carolina. We also document the disproportionate impacts of COVID-19 on different types of providers and disadvantaged communities. We use data from two time points (February and December) from 2018 to 2020 and a difference-in-differences design to isolate the effects of COVID-19. We find that COVID- 19 reduced county-level child care enrollment by 40%, and reduced the number of providers by 2%. Heterogeneity analyses reveal that family child care providers experienced not only less severe reductions in enrollment and closures than center providers, but a small growth in the number of family providers. Declines in enrollment were most substantial for preschool-aged children. COVID-19 did not appear to further exacerbate inequities in terms of enrollment amongst low-income communities, communities with a larger share of Black residents, or rural communities, although communities with a larger share of Hispanic residents had more provider closures. Our findings underscore the importance of family child care providers in the child care sector and providing continuing and targeted support to help the sector through this crisis. Implications for future policies are discussed.
The sustaining environments hypothesis refers to the popular idea, stemming from theories in developmental, cognitive, and educational psychology, that the long-term success of early educational interventions is contingent on the quality of the subsequent learning environment. Several studies have investigated whether specific kindergarten classroom and other elementary school factors account for patterns of persistence and fadeout of early educational interventions. These analyses focus on the statistical interaction between an early educational intervention – usually whether the child attended preschool – and several measures of the quality of the subsequent educational environment. The key prediction of the sustaining environments hypothesis is a positive interaction between these two variables. To quantify the strength of the evidence for such effects, we meta-analyze existing studies that have attempted to estimate interactions between preschool and later educational quality in the United States. We then attempt to establish the consistency of the direction and a plausible range of estimates of the interaction between preschool attendance and subsequent educational quality by using a specification curve analysis in a large, nationally representative dataset that has been used in several recent studies of the sustaining environments hypothesis. The meta-analysis yields small positive interaction estimates ranging from approximately .00 to .04, depending on the specification. The specification curve analyses yield interaction estimates of approximately 0. Results suggest that the current mix of methods used to test the sustaining environments hypothesis cannot reliably detect realistically sized effects. Our recommendations are to combine large sample sizes with strong causal identification strategies, and to study combinations of interventions that have a strong probability of showing large main effects.
Child care subsidies play an important role in stabilizing parental employment and helping low- income families access care. With limited federal requirements under CCDBG, states developed divergent subsidy program policies. Our study examines how variations in six state policy levers that capture CCDF administrative burdens and generosity relate to stability in children’s care in the CCDF program, known as subsidy “spells.”: (1) length of eligibility redetermination; (2) reporting requirements for income changes; (3) grace period for care before termination; (4) provider reimbursement rates; (5) parent copay amounts; and (6) difference between initial and continuing eligibility income thresholds. We exploit states’ changes in these policies during a 10- year period (2004-2013) using state fixed effects analyses to identify their impact on spell length. We find that administrative burdens robustly affect child care spell length; increasing states’ redetermination period length by one month increased state median subsidy spell length by 1.4 weeks, but requiring all changes in family income to be reported while enrolled in CCDF decreased spell length by 2.3 weeks. Switching to a 12-month redetermination period increased median spell length by 30%. CCDF policy generosity was not related to spell length. Results are discussed in the context of the 2014 CCDBG reauthorization.
We provide causal estimates of the effects of delayed kindergarten entry on achievement outcomes by exploiting a policy change in the birthdate enrollment cutoff in North Carolina that forced children born in a six-week window to redshirt. Using multiple peer group comparisons, we identify impacts on achievement and gifted or disability identifications in third through fifth grades. Delayed entry provides small benefits to students’ math and reading achievement, and reduced identification of a disability; these impacts operate through cohort position and age advantages, and not from hold-out year experiences. Redshirting differentially benefitted low-income students, but further disadvantaged non-white students.
