We present evidence of a positive relationship between school starting age and children's cognitive development from age 6 to 18 using a fuzzy regression discontinuity design and large-scale population-level birth and school data from the state of Florida. We estimate effects of being old for grade (being born in September versus August) that are…

Ready for Kindergarten! Survey (R4K!S) is a readiness assessment of children entering kindergarten about students' knowledge and skills within the first six to ten weeks of school. There are many interpretations of what constitutes "readiness." Vermont's concept of children's readiness is multidimensional; it includes social and…

In this study, it is aimed to determine the opinions of preschool teachers and classroom teachers about school readiness. As in the current situation, since this research is aimed to be a qualitative approach, the research is a case study of qualitative research type. In the study, interviews were conducted with a total of 25 teachers including 15…

This appendix provides additional details on the underlying data, statistical models, and results presented in "The Big Lift Descriptive Analyses: Progress across Three Kindergarten Classes." First the authors describe how they created each control and outcome variable and its source (e.g., parent report), followed by an overview of the…

This study aimed to examine the unique and interactive contributions of the quality of mothers' and fathers' relationships with their toddlers to the prediction of children's subsequent executive functioning (EF). The sample included 46 low-risk middle-class families. The quality of mother-child and father-child interactions was assessed…

Although 3-year-olds in the United States may attend prekindergarten prior to formal school entry in kindergarten, few investigations focus on the socioemotional foundations of classroom learning at age 3 and their relationship to later achievement. This study examined the relationship between age 3 readiness for group-based learning, modeled as…

This study aimed to determine the primary school students' readiness for school and analyze it according to some socio-demographic characteristics.

In this article, the authors examine the mathematical thinking and experiences that are unique to infants, toddlers, and 2-year-olds. They identify the four precursor mathematical concepts of attribute, comparison, pattern, and change and explore them in terms of why it is so important to attend to them, what makes them inherently mathematical and…
