Purpose: Against a backdrop of high-stakes assessment policies in the USA, this paper explores the challenges, promises and the "state of the art" with regard to designing standardized achievement tests and educational assessment systems that are instructionally useful. Authors deliberate on the consequences of using inappropriately…

Longitudinal change in the average Z scores for four groups of pupils sorted by quartiles was examined for its stability over three years. The data, collected from 1998 to 2009, was obtained from nine cohorts of Japanese junior high school pupils totaling 1,962 subjects. It showed illusionary declines among the mid-range pupils but improvements…

Purpose: To review the content and psychometric characteristics of 6 published tests currently available to aid in the study, diagnosis, and treatment of motor speech disorders in children. Method: We compared the content of the 6 tests and critically evaluated the degree to which important psychometric characteristics support the tests' use for…

A critical examination is made of standardized social studies achievement tests from a psychometric and reading perspective. Five major issues are identified that detract from the meaningful interpretation of student performance on standardized social studies tests. The issues discussed are (1) the reading dependency of social studies items, (2)…

Diagnostic judgments are often based on the comparison of two measures in order to judge whether the individual shows a genuine discrepancy in the traits or characteristics that the two measures represent. Until a perfect psychometric battery comes along, psychometricians can offer some guidance on the level of confidence to be placed in…

Principal components analysis of standardization sample data for the Comprehensive Test of Adaptive Behavior, involving 6,647 persons with mental retardation, found that a single factor accounted for 86 percent of the variance in category scores. Use of the Total Score and idiographic item clusters is psychometrically preferable to use of category…

Four confusing issues that have delayed progress toward an awareness that testing is not a source of unfairness for minority students are discussed: (1) the assumptions underlying most of our psychometric manipulations are often not acknowledged or understood; (2) the extent of the objectivity of psychometrics is frequently exaggerated; (3) the…

The issue of interpretation of standard test scores of minorities is discussed. The history of the issue is reviewed. The National Academy of Science's decision to reinterpret the scores of minorities is summarized. (YP)

This study provides data on norming and performance standards on the Stanford Achievement Test, 9th Edition, for both hearing and deaf students. It graphically analyzes these data in the context of interpreting individual test scores, examining achievement of groups of students, and specifically, interpreting test scores of high achieving deaf and…

Part of a special issue on adaptive behavior, the article discusses three assessment-related issues: (1) clarity of the construct of adaptive behavior; (2) norm samples for adaptive behavior scales; and (3) predictive validity of adaptive behavior scales. Improvements are noted in the standardization properties of major adaptive behavior scales.…

The Boder Test of Reading-Spelling Patterns is designed as an assessment of reading and spelling skills that allows specific diagnosis of the source and typology of reading problems. From a purely psychometric perspective, the BTRSP fails on virtually every characteristic examined. (BW)

The first edition of this book was written to give information about testing to people whose work gave them access to test results, but whose training included little or nothing about the use and interpretation of tests. Later editions have been intended for a broader audience as the need for understanding what test scores really mean has…

This package contains the Learning Disabilities Diagnostic Inventory (LDDI) and the LDDI examiner's manual. The LDDI is intended to help identify intrinsic processing disorders in children and adolescents. Items represent specific observable behaviors associated with learning disability (LD) in listening, speaking, reading, writing, mathematics,…

This article uses a question-and-answer format to describe the major categories of technical information usually presented in technical manuals for tests used by speech/language clinicians, including logical evidence of validity, empirical evidence of validity, types of reliability estimates, and practical issues in applying standardization data…

Federal law requires that individuals with handicapping conditions be administered assessments in ways that accommodate their disabilities without penalizing them. Validation studies are needed to evaluate the meaning of scores resulting from nonstandard test administrations. The limited number of these studies to date is reviewed. (SLD)
