The Long-Term Effect of North Carolina Pre-Kindergarten is Larger in School Districts with Lower Rates of Growth in Academic Achievement
Prior research has found that public investments in North Carolina’s pre-kindergarten program—NC Pre-K—generated positive effects on student reading and math achievement through eighth grade (Bai et al., 2020). This study examined whether the effect of NC Pre-K funding exposure is moderated by the educational environments children subsequently experience during elementary and middle school. The NC Pre-K effect on student reading and math achievement in eighth grade was found to be 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 school environments—consistent with a dynamic substitutability hypothesis of combined effects.
Comparing the School Readiness Skills of Public Pre-Kindergarten and Head Start Participants: A Systematic Review and Meta-Analysis
A systematic review of the literature (1965–2022) and meta-analysis were undertaken to compare the school readiness skills of children participating in public pre-kindergarten (pre-K) or Head Start. Seven quasi-experimental studies met the inclusion criteria for the meta-analysis and 38 effect sizes were analyzed. Results indicated no reliable meta-analytic effect in relation to children’s school readiness skills overall nor in relation to language, mathematics, or social-behavioral skills specifically. A small, positive meta-analytic effect favoring public pre-K compared to Head Start participation was found in relation to children’s emergent literacy skills (Hedges’ g = 0.17). Strategies are discussed to further equate the benefits of public pre-K and Head Start programming by facilitating greater cross-sector collaboration.
