This paper focuses on Scottish policy on additional support needs and its material outcomes. The central question addressed is the extent to which the Scottish additional support needs system undermines or reinforces existing social and economic inequalities. Administrative data highlight the inflation of the additional support needs category,…

Speech and language are central to the human experience; they are the vital means by which people convey and receive knowledge, thoughts, feelings, and other internal experiences. Acquisition of communication skills begins early in childhood and is foundational to the ability to gain access to culturally transmitted knowledge, organize and share…

Dyslexia is considered a learning disorder characterized by difficulty in learning to read, write, and spell despite conventional instruction, adequate intelligence, and sociocultural opportunities (TEC§38.003 cited in Texas Education Agency, 2014). The Texas Education Code (TEC) §38.003 makes provision for the evaluation and identification of…

In this paper, we describe the design, development, and initial validity evidence for the Screening to Assign Accommodations Tool (SAAT). The purpose of the SAAT is to identify students for whom construct irrelevant variance (CIV) might obscure measurement of their knowledge, skills, and abilities in mathematics. Once students are identified as…

The increased prevalence of autism spectrum disorder and documented benefits of early intensive intervention have created a need for flexible systems for determining eligibility for autism-specific services. This study evaluated the effectiveness of a training program designed to enhance autism spectrum disorder identification and assessment…

This report highlights the Massachusetts Department of Elementary and Secondary Education's 2015-2016 achievements and continuing efforts made toward maintaining a record of meeting requirements under Individuals with Disabilities Education Act (IDEA), reorganizing their system of student and family supports, and improving outcomes for students…

The proposed DSM-5 criteria for Autism Spectrum Disorder (ASD) depart substantially from the previous DSM-IV criteria. In this file review study of 131 children aged 2-12, previously diagnosed with either Autistic Disorder or Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS), 63% met the new DSM-5 ASD criteria, including 81%…

Background: Recent advances in genetics are particularly relevant in the field of intellectual disability (ID), where sub-microscopic deletions or duplications of genetic material are increasingly implicated as known or suspected causal factors. Data-driven reports on the impact of providing an aetiological explanation in ID are needed to help…

A Canadian context for the diagnosis of students with specific learning disabilities (LD) was investigated in the present literature review. A systematic review of the literature was undertaken to determine the current and best practices in this field. Overall, no agreed upon definition of LD was identified, although core similarities in…

An increasing number of students with dyslexia enter higher education. As a result, there is a growing need for standardized diagnosis. Previous research has suggested that a small number of tests may suffice to reliably assess students with dyslexia, but these studies were based on post hoc discriminant analysis, which tends to overestimate the…

This study examines the following properties of the Modified Checklist for Autism in Toddlers (M-CHAT) in an unselected low-risk sample: (a) the maximum age for screen administration; (b) the positive screen rate in the absence of follow-up telephone interviews and; (c) the distributional properties of positive screens. Data came from a…

Debate regarding the etiology of Autism Spectrum Disorders (ASD) is on the rise with numerous theories being put forth. Currently, the theory with the most empirical support is the interaction of multiple genes. Many studies have provided evidence that as the incidence of ASD increases so do genetic similarities. However, very little research has…

There is debate in the current literature regarding the permanence of an Autism Spectrum Disorder (ASD) diagnosis. We undertook a systematic review of the diagnostic stability of ASD to summarise current evidence. A comprehensive search strategy was used to identify studies. Participants were children with ASD. Risk of bias was assessed by…

Children with communication disorders present with a range of comorbid conditions. Occasionally one of the comorbid conditions manifests so strongly that the primary condition goes unnoticed by the clinician. This tendency to overlook comorbid health problems in the presence of a disability is referred to as diagnostic overshadowing. This is a…

Currently, both the DSM-IV-TR and ICD-10 preclude the diagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) in cases that present with an Autism Spectrum Disorder (ASD). This criterion will be removed in the upcoming DSM-V, but the relationship between ASD and ADHD, and in particular the prevalence of ADHD among the ASD population, remains…
