The distance between the birth date and the school entry cutoff has been repeatedly used as an exogenous instrument to examine the impact of several educational programmes. In this work, we analyse the validity of this instrument for the case of Argentina. Considering multiple waves of the Permanent Household Survey we detect the existence of…

In countries with a school-entry cutoff date, individuals born right after the cutoff are almost 1 year older than individuals in the same school cohort born right before that date. Abundant research has documented that, as a result of that extra year of maturation and skill accumulation, older students in a cohort outperform their younger peers.…

We analyze whether age relative to school classmates affects the likelihood of becoming famous. We measure such likelihood as the ratio of Wikipedia entries to births, by state and date of birth, among people born in 1969-1988 in the US. Using a reduced-form Regression Discontinuity Design, we find evidence that men born after the Kindergarten…

The present research attempted to investigate the impacts of gender and age on the freshly-graduated eighth graders' percentiles in the central high school entrance exam (LGS) in 2020. The sample of this causal-comparative study comprised 6,039 students selected from secondary schools in Isparta who took the LGS in 2020. The data were obtained…

Research on the effects of nursery school attendance still presents divergent results: a possible explanation is that the effects of child care on development outcomes can be modulated by individual characteristics, such as gender or temperament. In the present study, gender differences in nursery adaptation (evaluated by social skills and…

Self-care ability and social skills are potential areas of difficulty for preschool children. However, values about young children's self-care ability are different worldwide. This longitudinal study examined the influence of early self-care ability on social skills at the end of the preschool years. Participants were 509 children recruited from…

There is growing evidence that school starting age impacts children's likelihood of receiving special education services, but less is known about variations in this effect. Using a regression discontinuity design, I found that the youngest students in a kindergarten cohort are 40% more likely (p < 0.001) to be placed in special education than…

Understanding the factors that influence student outcomes is crucial for both parents and schools when designing effective educational strategies. This paper explores the impact of peer age on both cognitive and non-cognitive outcomes using a randomized sample of middle school students. By analyzing how exogenous variations in peer age affect…

Few elementary students on the Commonwealth of the Northern Mariana Islands (CNMI) are scoring at grade level or higher on the ACT Aspire reading assessment. To better understand factors associated with the reading proficiency of CNMI grade 3 students, stakeholders there asked the Regional Educational Laboratory Pacific to examine the demographic…

Few elementary students in the Commonwealth of the Northern Mariana Islands (CNMI) are scoring at grade level or higher on the ACT Aspire reading assessment. This study examined data on students who enrolled in grade 3 in a CNMI public school from 2014/15 to 2018/19 to understand their grade 3 reading performance. The study used administrative…

Using an unanticipated policy reform in Mexico that shifted 4 months the cutoff date for elementary school eligibility in 2006 and information on academic performance of 15-year-old students from the Programme for International Student Assessment (PISA) 2018 survey, who entered first grade in 2006, this paper estimates the effects of starting…

The purpose of this project was to understand the association between age at kindergarten entry and social-emotional competence across grade levels, including kindergarten, grade 3, and grade 5. While the research indicates that there can be an initial academic advantage for the delayed entrant before grade 3, there is far less research that has…

Nearly 14% of students in the United States receive special education services in public schools (NCES, 2017). Special education programs serve students with a wide range of developmental differences and vary considerably across schools and districts (National Research Council, 1997). Likelihood of identification for special education services…
