The research concerning three major types of measures designed to identify young children at risk of experiencing school problems is reviewed. Teacher perception, test batteries, and single instruments are discussed in terms of general considerations for use, advantages, and disadvantages. (Author/DB)

Most conceptualizations of learning disabilities are based on discrepancies between ability and achievement, but the dimensions of this parameter have not been documented. Discrepancies for 83 third graders, 48 fifth graders, and 50 twelfth graders were compared. The use of ability achievement discrepancies to determine the need for special…

The study compared earlier identified (grades 2-4) to later identified (grades 5-8) learning-disabled students' test scores (Woodcock Reading Mastery Tests and Wechsler Intelligence Scale for Children) upon identification and over time in special education. No significant between-group differences were found at identification. Over time (two…

The original authors respond to a critique of their meta-analysis of 94 studies which had failed to support the presence of distinctive Wechsler Intelligence Scale for Children profiles for learning disabled children. The critique contended such a pattern does exist. (Author/DB)

As part of a continuing dialog concerning the validity of a meta-analysis of 94 studies suggesting that there is a lack of any distinctive pattern in the Wechsler Intelligence Scale for Children (Revised) profiles for learning disabled children, this article maintains the view that such differences do exist. (DB)

The article looks at the concept of discrepancy between ability and achievement in conceptualizations of learning disabilities. Comparison of ability and achievement scores found generally small average discrepancies, though some wide ranges were evident. Implications of the findings for current and future use of discrepancies as estimators of…

Evaluation of the Luria-Nebraska Neuropsychological Battery's utility in distinguishing between 30 male adolescents diagnosed as learning disabled (LD) and 30 matched non-LD students indicated that the battery correctly classified 90 percent of the sample with 6.7 percent false positives and 13.3 percent false negatives.

This article examines the problem of definition in learning disabilities. It discusses the failure of conceptual definitions to provide a clear idea of what learning disabilities are, examines the true nature of available definitions as stipulative definitions, and notes the difficulty in conceptualizing and implementing operational definitions.…

Reanalysis of data derived from a meta-analysis of the Wechsler Intelligence Scale for Children-Revised, using a learning disability index derived from a principal-components analysis, found that the test discriminated reliably between 9,372 learning-disabled children and their non-disabled peers. (Author/CB)

The study evaluated the utility of Kaufman-Assessment Battery for Children (K-ABC) subtests in differentiating learning-disabled children from students with other handicapping conditions, and compared K-ABC subtests with Wechsler Intelligence Scale for Children-Revised subtests. Results showed that subtest scores did not enhance differential…

When 43 experienced school psychologists were asked to evaluate discrepancy scores, it was found that they made inconsistent choices, failed to use standard statistical procedures for testing differences between scores, and tended to misinterpret percentile ranks as useful for discrepancy analysis. Implications for learning-disabilities…

The National Joint Committee for Learning Disabilities' definition of learning disabilities is presented, followed by a discussion of parameters to be considered in operationalizing the definition. Major definitional issues are then explored, including using testable and meaningful constructs, linking definitions to neuropsychological evidence,…

Descriptive information was gathered about 790 students with learning disabilities in primary, intermediate, and secondary grades. Results included identification of learning disabilities peaked in first grade; 76 percent of these students were identified by the end of grade 5; and students with more severe discrepancies tended to be identified at…

Application of cluster analysis to 57 elementary grade children with learning disabilities resulted in identification of 5 subgroups: (1) children with language deficits; (2) children with visual deficits; (3) children with no notable deficits; (4) children with very poor reading achievement but very high self-concept; (5) children with behavior…

The paper examines the issue of disproportionate representation of limited-English proficient (LEP) Hispanic students in classes for the learning disabled. Inadequate assessment, evaluation, placement, and re-evaluation of LEP students are noted. Sixteen policy considerations are identified to help school districts ensure that LEP learning…
