The aims of this study were to examine vocabulary scores of 5-year-old children who are deaf or hard of hearing (DHH), as well as the impact of early enrollment in specialized intervention on vocabulary outcomes. Receptive and expressive vocabulary scores were analyzed for 342 five-year-old children who are DHH enrolled in specialized listening…

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…

Attention deficit hyperactivity disorder (ADHD) is a debated phenomenon and the link between schooling and the occurrence of ADHD diagnoses is worth critical scrutiny. This paper contributes to the academic debate by providing a literature review of the evidence on the influence of relative age effect (RAE) on being diagnosed with ADHD. Firstly,…

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…

Much of the literature estimating disproportionality in special education identification rates has focused on socioeconomic status, race, and gender. However, recent evidence suggests that a student's school starting age also impacts the likelihood they receive special education services, particularly in the early grades. I build on the evidence…

This article shares qualitative analysis of online discussion threads between student teachers in seven countries. The student teachers engaged together online to share intercultural perspectives and experiences on a range of topics of relevance to education systems, policy, teacher education, and childhood. In 2017, participating countries were:…

We investigated whether children's reading and mathematics growth trajectories from kindergarten to fifth grade inter-related, and to what extent disability and minority status interacted to predict their achievement trajectories. We conducted secondary data analysis based on a nationally representative sample of 6,446 U.S. schoolchildren from the…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This final report from the program's evaluation focuses on results from a five-year…

This study examined relationships between specific data on students referred for and placed in the exceptional children's program. The context is a rural North Carolina county and included 206 records of K-6th graders spanning academic years 2007-08, 08-09 and 09-10. The kindergarten entrance ages of students were divided into categories of on…

This dissertation examines the student academic achievement through various mechanisms, put in place by the public school district, classroom student behavior, and negative external shocks to the students' living environment. I examine the impacts of various treatments on student short and long run academic outcomes such as math and English test…

California's Kindergarten Readiness Act of 2010 established transitional kindergarten (TK), the first year of a two-year kindergarten program for students affected by the change in the birthdate cutoff for entry into kindergarten from December 2 to September 1. This fifth short report in a series highlighting findings from the Study of…

The current study examined whether the parental practice of delayed kindergarten entrance, also known as academic red-shirting, was associated with gains in academic achievement among children with learning disabilities. Results indicate no significant differences in the academic achievement among children with learning disabilities who were…
