Objective: We leveraged common genetic variation underlying ADHD, educational attainment (EA) and cognition (COG) to understand the nature of the Behavior Rating Inventory for Executive Functions (BRIEF) and its relationship to academic functioning. Method: Participants were 991 youth, ages 7 to 17, consecutively referred for neuropsychiatric…

This study examined the scoring errors across three widely used achievement tests (Kaufman Test of Educational Achievement--Second Edition [KTEA-2], Woodcock--Johnson Tests of Achievement--Third Edition [WJ-III], and the Wechsler Individual Achievement Test--Third Edition [WIAT-III]) by novice examiners. A total of 114 protocols were evaluated for…

The simple view of writing suggests that written composition results from oral language, transcription (e.g., spelling/handwriting), and self-regulation skills, coordinated within working memory. The model provides a number of implications for the interpretation of psychoeducational achievement batteries. For instance, it hypothesizes that writing…

The Wechsler individual achievement test, third edition (WIAT-III) is a popular individually administered achievement battery. Despite its ubiquity in assessment practice, scant research into its structure exists. We analyzed the structure of the WIAT-III in a sample of students in Grades 3-12 referred for special education evaluations (n = 355).…

In this study, we explored the potential of two forms of discussion (disciplinary vs. traditional) for 39 sixth- and seventh-grade students with or at risk for learning disabilities (LD), before writing historical arguments. Nine teachers who led small group discussions in six heterogeneous social studies classrooms implemented the intervention.…

This article reports on a qualitative secondary data analysis of a study of upper elementary students' narrative writing progress in U.S. rural schools. It compares students working online in pairs with those working alone. We explain why the intervention had some positive effects for struggling writers but few effects for skilled writers. The…

Students with specific learning disabilities (SLDs) represent a large proportion of those receiving special education services in U.S. schools, but the relationship between student-level variables and SLD identification is still not well understood. The purpose of this study was to examine the extent to which data collected as part of a…

There is often confusion about the terms used to label or describe a reading problem. Clinicians and researchers use different terminology than the schools. For example, medical professionals, psychologists, and other practitioners outside of the school often use the term "dyslexia," "reading disorder," and "specific…

Demonstrating comprehension of text is a complex skill that is an area of difficulty for many students with autism spectrum disorder (ASD). Shared story reading is an intervention that has a history of effectiveness in teaching literacy skills to students with extensive support needs. This study used a multiple probe across participants design to…

Oral language and word reading skills have important effects on reading comprehension. The Wechsler Individual Achievement Test-Third Edition (WIAT-III) measures both skill sets, but little is known about their specific effects on reading comprehension within this battery. Path analysis was used to evaluate the collective effects of reading and…

This study used a multiple probe across participants design to examine the effects of a model drawing strategy (MDS) intervention package on fraction comparing and ordering word problem-solving performance of three Grade 4 students. MDS is a form of cognitive strategy instruction for teaching word problem solving that includes explicit instruction…

This quasi-experimental study examined differences in student reading outcomes. Participants were third grade non-struggling readers. Intervention classrooms included core curriculum instruction plus evidence-based reading comprehension instruction and differentiated repeated readings. Comparison classrooms provided core curriculum instruction…

In this study, we intend to determine if reading tests aloud provides a differential boost to youth with elevated symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) relative to same-aged peers. Participants were 36 youth, 44% with or at risk for ADHD, who participated in a week long summer camp. Over the course of the week, youth attended…

The purpose of this phenomenological, qualitative study was to illuminate the lived, shared experiences of parents of gifted children diagnosed with autism spectrum disorder. Thirteen parents were interviewed and the interviews were transcribed and qualitatively analyzed. This article specifically examines the parents' experiences navigating the…

This study of 182 secondary special education students with emotional and/or behavioral disorders investigated their classification by their school districts, in particular how well they were distinguished and represented by their federal categories. The districts used four classification groups (emotional disturbance, other health impairment…
