Specific learning disorder (SLD) identification is arguably one of the most significant controversies in school psychology. One component of this issue is that guidelines and practices vary substantially across professionals and states, which leads to inconsistent identification rates and outcomes for students. To assess the extent of this problem…

The assessment procedures within Response to Intervention (RTI) models have begun to supplant the use of traditional, discrepancy-based frameworks for identifying students with specific learning disabilities (SLD). Many RTI proponents applaud this shift because of perceived shortcomings in utilizing discrepancy as an indicator of SLD. However,…

Four primary issues are covered: the role of different measurement models in disparities of LD children serviced across states, types of students served as LD but not actually LD, components of severe discrepancies between aptitude and achievement, and state of the art in evaluating LD students.

Five formulas for identifying discrepancies for eligibility as learning disabled (LD) were applied to 137 children (ages 6-14) already diagnosed as LD. Among results cited was that 64 percent were not identified as LD by any formula. Issues concerning the use of discrepancy formulas for LD screening are discussed. (Author/JW)

The No Child Left Behind Act (NCLB) firmly insists that performance analyses use disaggregated scores. Disaggregation, according to NCLB, involves measuring and reporting achievement for separate subgroups of children so that achievement problems in any one subgroup are not disguised when averaged or aggregated with higher achieving children in…

Technical problems in the assessment of learning disabilities (LD) are only a small part of the problems leading to the misidentification of children in this category of handicap. Given all the other motives and purposes served by labeling a child LD in school, apparently sound measurement advice may actually do more harm than good. (LC)

Data from 143 children with reading disabilities (RD), 100 with arithmetic disabilities (AD), and 121 controls (ages 6-16) found the RD and AD groups had significantly lower scores on all verbal IQ subtests. Many also showed significant differences between verbal and performance IQ scores, but so did many controls. (Contains references.)…

This book offers 27 papers addressing critical issues in the assessment of students with all kinds of learning disabilities. Papers have the following titles and authors: "Critical Issues in the Measurement of Learning Disabilities" (G. Reid Lyon); "A Matrix of Decision Points in the Measurement of Learning Disabilities" (Barbara K. Keogh);…

Considerable variation exists across response-to-intervention (RTI) approaches. There is currently insufficient research on outcomes associated with these different RTI approaches to inform decision-making. However, school psychologists who are asked to work within an RTI model need guidance to select an approach that has a high likelihood of…
