The article reviews the literature on the quantification of achievement-aptitude differences in learning disabled students, outlines and discusses criteria for new and more adequate procedures, and presents step-by-step procedures that can be routinely followed. (Author/DLS)

Comparison of student test scores between states, school districts, and even schools continues to be a popular measure of student achievement. However, these comparisons reveal little about the quality or effectiveness of educational programs, only the varying difficulty of educating different populations of students. This report uses U.S. Census…

Performance assessment (observational assessment) can be an effective alternative to traditional paper and pencil tests when measuring academic achievement. Benefits of performance tests include: (1) testing knowledge synthesis rather than just knowlege acquisition; (2) allowing for diagnosis of individual needs and an immediate adjustment of…

During the spring of 1981, a San Juan Task force of special education staff members developed revised criteria for the identification of students with specific learning disabilities (SLD). This report covers the second year of discrepancy criteria implementation. It examines the identification of 225 students with SLD during the first semester of…

This study, involving 1,069 children (ages 9-14) referred for evaluation of learning disability, used 3 definitions of reading disability to provide criteria for 5 groups of children based on discrepancy between intelligence quotient (IQ) and academic achievement. Results question the validity of segregating children with reading deficiencies…

Provides guidelines to make grades a better assessment of learning. Argues that, for any assessment task to be fair, its content, context, and performance expectations should (1) reflect knowledge appropriate to all students; (2) tap knowledge that all students have had time to acquire in the class; and (3) and be as free as possible of cultural,…

This article argues that the regression-based discrepancy method used in the diagnosis of learning disabilities is invalid because it is inconsistent with the underlying underachievement concept of which it is intended to be the operationalization. It is mathematically demonstrated that the regression-based discrepancy method largely reflects…

This article evaluates conclusions in Van den Broeck's article (2002) that argue the regression-based discrepancy method (RDM) used in learning disabilities diagnosis is invalid because it is inconsistent with the underlying underachievement concept of which it is intended to be the operationalization. It concludes acceptable models support the…

This article responds to a critique by Willson and Reynolds (2002) that argued for the use of the regression-based discrepancy method (RDM) for identifying learning disabilities. It argues the statistical and theoretical counterarguments are based on a misreading of the statistical models presented. (Contains 8 references.) (Author/CR)

This report quantitatively shows the progress of students in the area of general education development at College of DuPage (Illinois). The aims of general education are to promote students' understanding and appreciation of their culture and environment; to develop a system of personal values based on accepted ethics that lead to civic and social…

Two key concepts in diagnosing learning disabilities ("severe discrepancy" and "process dysfunction") are reviewed, and their relationship to the habilitation of learning is discussed. Guidelines are given for calculating a severe discrepancy, and the evaluation of processing skills is discussed. Strength models of remediation…

This document discusses legal considerations in the identification of Michigan students with learning disabilities and suggests guidelines for meeting legal requirements in a systematic and consistent manner. An introduction outlines issues and problems related to the assessment of learning disabilities and provides a rationale for the importance…

Considers approaches to assessing writing disabilities that use theory-based process measures to explain discrepancies between intelligence quotient (IQ) and achievement; may define learning disabilities independent of IQ; and employ branching diagnosis based on selected tests rather than all tests in standard battery. Outlines model for using…

The purpose of this study was to explore whether, and if so how, ongoing measurement and evaluation procedures affect the instruction that special educators provide and the educational decisions that they make. Eighteen experimental group teachers employed specific continuous evaluation procedures while 21 contrast group teachers employed…
