Some students may be diagnosed with a learning disability in mathematics or dyscalculia, whereas other students may demonstrate below-grade-level mathematics performance without a disability diagnosis. In the literature, researchers often identify students in both groups as experiencing math difficulty. To understand the performance of students…

All but seven U.S. states have laws that govern some aspects of dyslexia screening, intervention, or teacher training in public schools. However, in the three states that mandate child-level reporting, data indicate lower than expected rates of dyslexia identification when compared with commonly accepted dyslexia prevalence rates. To better…

Since the emergence of the field of learning disabilities (LD) in the late 1960s and early 1970s, controversy has surrounded issues regarding methods used for identification. The prevalence of students identified as LD increased steadily from the 1970s until the beginning of the 21st century, at which time it has decreased until at least 2011 (the…

Programmatic, multidisciplinary research provided converging brain, genetic, and developmental support for evidence-based diagnoses of three specific learning disabilities based on hallmark phenotypes (behavioral expression of underlying genotypes) with treatment relevance: dysgraphia (impaired legible automatic letter writing, orthographic…

To determine the degree of controversy or consensus regarding definitions at the state level, questionnaires focusing on six learning disability topics were sent to each state education agency (SEA) and the District of Columbia. In general, more consensus than controversy exists when broad areas are considered. Changes in some SEA definitions…

Nine procedures assessing the magnitude or statistical significance of ability-achievement discrepancy dealing only with magnitude were evaluated and found to possess one or more serious statistical deficiencies. The approach with the greatest potential involves assessing the statistical significance (reliability) of a discrepancy score and then…

Explores current policies and practices concerning the definition, identification, and educational needs of students who are both gifted and learning disabled. Recommendations stress the need for less rigid definitions and cutoff scores for program eligibility and the provision of a wide variety of settings (resource rooms, special classes) and…

The author describes the use of the revised Detroit Tests of Learning Aptitude and the Woodcock-Johnson Psycho-Educational Battery for students with learning disabilities. He cautions about making a diagnosis on the basis of only one test. (CL)

The author asserts that the diagnosis learning disability is applied too often and too loosely. It is recommended that the possibility be considered that poor school adjustment may be due simply to immaturity and unreadiness rather than to some general learning disability. (Author/CL)

Results of surveying of 41 teachers who had experience with learning disability preassessment teams (intended to focus on regular classroom intervention prior to comprehensive evaluation) suggested that teachers were pleased with preassessment team members but did not agree that the teams' intervention recommendations were successful in correcting…

The author suggests that controversies over defining learning disabilities (LD) have resulted from confusion between diagnosis and definition and from disagreement over the discrepancy issue. He further suggests that LD students are a subset of age- and ability-referenced underachievers. (CL)

A review of the literature regarding the utility of Wechsler Intelligence Scale for Children-Revised (WISC-R) with learning disabled (LD) students was conducted. It is concluded that the WISC-R can be an adjunct to LD diagnosis and one step in educational planning for the LD student. (Author)

In an attempt to refine the definition of learning disabilities, a new term, dyssymbolia is proposed. (CL)

Scatter analysis among the Tests of Cognitive Ability for the Woodcock-Johnson Psycho-Educational Battery was conducted on the performance of 3,566 Ss (grades one to 12) from the standardization sample. Examining scatter on the Tests of Cognitive Ability and identifying specific "types" of learning disabilities using this test are discouraged.…

Investigation of the relationship between a statistically determined severe discrepancy between expected and actual achievement levels and subsequent labeling of 733 students as learning disabled found only a slight majority of labeled students manifesting a severe discrepancy suggesting this criterion is inconsistently applied in making…
