Few empirical investigations have evaluated learning disabilities (LD) identification methods based on a pattern of cognitive strengths and weaknesses (PSW). This study investigated the reliability of LD classification decisions of the concordance/discordance method (C/DM) across different psychoeducational assessment batteries. C/DM criteria were…

Item response theory (IRT) and related latent variable models represent modern psychometric theory, the successor to classical test theory in psychological assessment. Although IRT has become prevalent in the measurement of ability and achievement, its contributions to clinical domains have been less extensive. Applications of IRT to clinical…

Purpose: To describe a cognitive neuroscience model of memory that can be used to guide assessment and promote consistent terminology among members of the rehabilitation team, and to relate the model to frequently used assessment measures. Method: Description of a model of memory, description of how frequently used memory measures relate to the…

The problem of choosing educational and psychological tests to identify students with learning disabilities is discussed within a cost-efficiency framework. An efficiency index for estimating the classification accuracy of tests is presented and the use of expert judgment and the cost-effectiveness ratio is demonstrated with a numerical example.…

The data collected in higher education research are not always quantitative or continuous. Statistical methods using the log-linear model provide the institutional researcher with a powerful set of tools for addressing research questions when data are categorical. (Author/MSE)

Regression analysis is one of the most frequently used statistical techniques in institutional research. Principles of least squares, model building, residual analysis, influence statistics, and multi-collinearity are described and illustrated. (Author/MSE)

Path analysis and linear structural relations (LISREL) provide the institutional researcher with some extremely powerful statistical tools. However, they must be applied and interpreted carefully with a full understanding of their limitations and the statistical assumptions on which they are based. (Author)

Wechsler Intelligence Scale for Children, Revised (WISC-R) Verbal, Performance, and Full Scale IQ's were compared with Bannatyne recategorized WISC-R scores for groups of non-handicapped, educationally disadvantaged, learning disabled, and regular classroom Navajo Indian children. No definitive evidence was found to support the use of the…

A liberal interpretation of Section 151 of Public Law 93-380, to implement effective local evaluation of Title I programs, is supported. Weaknesses are cited: (1) nationwide impact data, (2) unsound aggregation of Title I achievement gains, and (3) lack of consideration of alternative evaluation methods. (MH)

Seven considerations in designing the Title I Evaluation and Reporting System are reviewed: satisfying state, local, and federal needs; summative evaluation; differences in Title I subprograms; local use of different achievement tests; comparative analysis data; use of approved evaluation designs; and use of a common reporting metric. (MH)

This article considers the models and beliefs of language clinicians, as reflected by their choice of specific assessment instruments or measurement methods. Differences in construct and philosophy are demonstrated in a review of personality and vocational preference inventories and several subtests of sentence production. (DB)

When selecting standardized reading tests for purposes of decision making, the school psychologist must answer several questions, such as "What reading skills do I wish to assess?" or "How do I judge if the test is technically adequate?" Recommendations for test selection are made within the context of these questions.…
