In the context of an emerging new additional learning needs (ALN) system in Wales, this research explores who was likely to be identified with special educational needs (SEN) under the previous system. Our study reveals analysis of linked Welsh education and health data on SEN identification in learners in mainstream education settings born…

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…

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…

We used pupil-level data from the National Pupil Database in England to conduct a longitudinal analysis of the identification of moderate learning difficulties (MLD) and social, emotional, and mental health difficulties (SEMH) among 550,000 pupils ages 5 to 11 years. Survival analysis was used to determine the hazard ratios (HRs) for time to first…

Students' self-determination plays a critical role in both in-school and post-school outcomes. This study examined the self-determination of English learners with disabilities in secondary school, based on a secondary analysis of the National Longitudinal Transition Study 2012 (NLTS 2012). The NLTS 2012 youth survey, conducted in English and…

This study used a statewide longitudinal sample to examine mathematics achievement gaps and growth in students with and without disabilities and to examine the impact of different methods of determining disability group membership on achievement gaps and growth. When disability status was determined on the basis of special education placement each…

The processes around the identification of special educational needs (SEN) should mean that those pupils who need most help receive it. However, there are concerns that this process is not working and there is an over-identification of pupils with SEN. Previous international research has shown that summer-born children are more likely to be…

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also…

Comparison of psychometric profiles of learning disabled and non-LD students (total N=223) across LD status, district, and age variables indicated that only severity of academic underachievement consistently differentiated the LD and non-LD pupils. Comparison across districts revealed different LD profiles despite use of identitical eligibility…

A discriminant analysis of characteristics of students with behavioral disorders in three progressively more intensive placements indicated that age at time of diagnosis was the strongest discriminating variable contributing to placement outcomes. Younger, brighter students tended to be mainstreamed, and older students with more externalizing…

This brief paper summarizes warning signs of learning disabilities in preschool children, elementary school children, and secondary school children. It notes that learning disabilities are presumed to arise from dysfunctions in the brain resulting in significant difficulties in perceiving information, processing and/or remembering information,…

Results suggest that, especially at older ages, children who are both aggressive and withdrawn represent a less mature, less socially skilled group that is potentially at risk for poor adjustment later in life. (Author)

Using data from the Special Education Elementary Longitudinal Study that included more than 11,000 students (ages 6-12), this study explored the primary disability classification assigned to students by their schools, the variety of disabilities that parents reported, functional limitations associated with students' disabilities, disability…

This brief paper reports on a study of learning disabilities in students with deafness. The study attempted to first determine to what extent deficiencies in communication skills affect the screening of deaf students for learning disabilities and, second, to describe the phenomenon of learning disability in students with deafness. The research…
