The prevalence of disability diagnoses among young children has risen significantly over recent decades. This growth has prompted inquiries into the identification processes, notably focusing on teachers who are the primary sources of referrals. While some studies have examined child age as a relevant predictor of disability referral, minimal…

Taking the school bus has long been an integral part of the school experience in the U.S. However, not much is known about how school transportation relates to getting to school each day, particularly for students with disabilities. This study used ECLS-K: 2011 to explore two issues. First, we examined what characteristics are associated with…

Background and context: Despite the growing importance of computer science (CS) education, high-quality CS curricula for students in kindergarten to lower elementary grades are lacking. It is also unclear how students from underrepresented groups such as female students, students from low socioeconomic status, and students with disability respond…

Understanding achievement and discipline trajectories of Latinx students is critical given disproportionate dropout/pushout rates of Latinx students from schools across the U.S. Using a Critical Race Theory framework, the current study examined longitudinal associations amongst a sample of (N = 1672) Latinx youths' school readiness at kindergarten…

Student absenteeism is a barrier to learning and an issue that requires policy intervention. Students with disabilities are of particular concern, as they miss school more often than students in any other demographic group. Affecting a key attribute of school structures, policies promoting full-day kindergarten began as an effort to improve…

A meta-analysis of single-case design research was conducted to evaluate the effectiveness of mathematics interventions for elementary grade (K-5) students with mathematics difficulties (MD) and mathematics learning disabilities (LD). The study examined whether intervention effectiveness varied as a function of participant characteristics (i.e.,…

Student-teacher relationship quality (STRQ) influences a variety of student outcomes, including academic, social, and behavioral functioning (McGrath & Van Bergen, 2015). Less is known about the importance of STRQ for preschool students with disabilities. Many studies are conducted with school-aged, typically developing students (Ansari et…

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…

It is important to understand how longitudinal patterns of special education placement differ from cross-sectional incidence estimates in order to improve measurement precision and better target assistance to students with disabilities. This study used latent class growth analysis in a national-level data set to classify four trajectories of…

Beginning in the fall of 2017, Maryland severely restricted the use of out-of-school suspensions in grades PK-2. The policy presented a valuable opportunity to examine the effects of state-level discipline policies. This study researched the effects of the suspension ban on student discipline outcomes (e.g., number and frequency of different…

The Early Literacy Program focuses on the development of early literacy skills, with additional emphasis on intervention for students at risk of not meeting grade-based reading benchmarks. Districts and charter schools (LEAs) assess, and report to the state, students' reading composites and benchmarks three (3) times a year using the Acadience…

This study measures the impact of 95 Percent Group's Phonological Awareness Lessons (PA Lessons), an intervention program designed for kindergartners for Tier 2 or 3. The study is a replication of a study conducted in the same medium-sized school district in California during 2021-2022. Students Below or Well Below Benchmark in Fall 2022 were…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

Research-based instruction is necessary to support students' reading development, and professional development (PD) is a critical avenue to ensuring high-quality instructional practices. To date, there has been no comprehensive review focused on the effects of teacher PD on student reading achievement. As such, the purpose of the present…

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…
