Describes popularity of using percentile rank and offers interpretation of use of percentile rank with normal and skewed score distributions. Explains that, because percentile rank is not linear transformation of raw scores, percentile-rank transformation in lower and upper part of raw-score distribution relates percentile rank and raw scores…

Presents age-referenced tables for Wechsler Preschool and Primary Scale of Intelligence-Revised that provide differences required at .05 and .01 levels of significance between any Verbal scale subtests and average of Verbal scale subtests, any Performance scale subtests and average of Performance scale subtests, and any subtest with average of all…

Examined the interpretation of measures of moral development to individuals from three phases of test interpretation. Interpretations based on the meaning of the scale, the meaning of the score, and specific meaning to the individual are explored. (Author)

Discusses knowledge needed by counselors to help in choosing appropriate tests for particular clients and problems under consideration and in properly interpreting test scores and integrating them into the total assessment process. Focuses on both statistical and technical knowledge about tests and substantive psychological knowledge about…

Provides tables of Wechsler Individual Achievement Test (WIAT) subtests and composite predicted-achievement standard scores based on Wechsler Intelligence Scale for Children-Third Edition (WISC-III) Verbal and Performance intelligence quotients (IQs). Tables allow examiners to determine quickly ability-achievement discrepancies based on WISC-III…

Addresses practical issues concerning test score interpretation. Percentile bands are recommended for reporting to clients the extent and limits of what test scores reveal. Variety of suggestions and examples are provided for rendering interpretations meaningful. (Author)

Describes the role of information on score reliabilities, significance of score differences, intercorrelations of scores, and differential validity of score patterns on the interpretation of results from multiscore batteries. (Author)

Describes a course model for counselor education programs which focuses on competency in the interpretation of individually administered psychoeducational tests and reports. Includes information on development of the course, competencies and skills taught, course content and procedures, and course evaluation. (LLL)

Provides new confidence intervals for Wechsler Intelligence Scale for Children-Revised (WISC-R) to improve accuracy over existing tables. Includes alternative confidence interval tables for WISC-R quotients at extreme levels where current tables are least accurate. New tables center confidence intervals on estimated true intelligence quotient and…

Addresses the issue of counselor expertise in test interpretation. Discusses norm-referenced versus criterion-referenced interpretation, interpreting the precision of the information, interpreting the meaning of the construct and its relevance to the decision, and general precautions regarding test interpretation. (LLL)

Contends that one basic limitation of measurement techniques is that tests cannot measure unique characteristics, but only traits common to many people. Discusses limitations regarding intelligence, interest, and personality tests and concludes that test scores give us clues to be followed rather than definite measurements. (LLL)

Considered methods of evaluating the pattern of subtest scores on the Wechsler Adult Intelligence Scale-Revised. The rationale and method for calculating the size of the significant difference between a subtest and the mean of the subtests scores for an individual are described. (JAC)

Discusses the significance of confidence intervals around IQ scores based on a misleading interpretation of the standard error of measurement terms provided in the Wechsler Adult Intelligence Scale-Revised (WAIS-R) manual. Presents standard error values and a table for determining the abnormality of verbal and performance IQ discrepancies.…

Investigates psychometric properties and overall utility of Family-of-Origin Scale. Concludes that, although much of the recent criticism of this instrument may be justified, with changes (primarily in interpretation) the instrument remains useful. Taking this measure as an example, discusses problems inherent in the use of individual self-report…

Reviews WISC-R factor analytic findings for developing a scheme for regrouping WISC-R subtests, consisting of verbal comprehension and spatial subtests. Subtests comprising these groupings are shown to have more common variance than specific variance and cluster together consistently across the samples of WISC-R scores. (Author/JAC)
