A comparison of the Wide Range Achievement Test (WRAT) and the Peabody Individual Achievement Test (PIAT) indicates that the two should be used interchangeably only with caution and understanding of the differences. While there is a moderate to high correlation between the test scores, nevertheless, the two have distinctly different strengths and…

This research addresses the question of the comparability of equal scores on the same test from children in different grades. The results indicate that the scores are comparable, and support the assignment of Iowa Tests of Basic Skills levels that match the child's developmental level. (Author)

Compared the derived mental age (MA) of the Stanford-Binet to the test age (TA) of the Wechsler Intelligence Scale for Children (Revised) in 100 children. For subjects whose WISC-R scores fell within the TA table, the two were comparable. When extrapolated TAs were required, the scores were not comparable. (Author/JAC)

Explored the relationship between the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) for 37 Native American children. The PPVT-R standard scores correlated significantly with the WISCR-R Verbal IQ, Performance IQ, and Full Scale IQ. The mean PPVT-R standard score was significantly…

Examined the influence of intelligence level on the performance of children (N=121), aged 9-14, on the Halstead Reitan Neuropsychological Test Battery. Results indicated a significant influence of IQ on level of performance on six of 14 measures. Tests of problem-solving abilities, language skills, and auditory perceptual analysis were most…

The National Assessment of Educational Progress (NAEP) makes possible comparison of groups of students and provides information about what these groups know and can do. The scale anchoring techniques described in this chapter address the latter purpose. The direct method and the smoothing method of scale anchoring are discussed. (SLD)

WISC-Rs and Stanford-Binets were administered to 50 children with developmental disabilities referred for comprehensive evaluations. Fifty-four percent of the children received different classifications using the two instruments. Different classifications of intellectual level may be derived for the same child depending upon which test is used.…

Results indicated that despite very high correlations between deviation quotients and traditional measures, changes of potential diagnostic significance occurred in scores of over half the sample (N=2,200). Discusses the potential utility of the factorially pure deviation quotients. Presents a table for translation of scaled scores into these…

Recent test results reveal that the test score decline has ended, but the legacy of this highly publicized educational episode continues. One widespread interpretation of the decline and recovery is that permissiveness and a collapse of standards in the late 1960s led to the decline and that a return to the basics and to tougher standards caused…

A method, involving the plotting of scores on a grid, was developed for use in comparing scores from the Gottschalk-Gleser content analysis scales, which have different Black and White norms. These profile forms can be used to pictorially examine psychological state or trait scores derived from speech. (Author/GDC)

How two students with the same number-correct score, calculated by dramatically different patterns of responses, can achieve the same ability estimate is demonstrated. The present study investigated the incidence of person misfit to the model in a nationally standardized test of achievement devised using the Rasch item response theory model. It…

This paper examines a number of issues surrounding the addition of a dimension of international comparisons to the National Assessment of Educational Progress (NAEP). The basic position of the paper is that adding an international dimension to NAEP is certainly possible, but some problems will need to be overcome. Non-issues are identified and…

Four new versions of an acoustic structuring test were developed, administered, and analyzed in order to produce better tests and to contribute to better understanding of the abilities measured by these tests. The tests consist of tape recordings of patterns of musical notes played on an electric organ or an acoustic guitar. Item analyses and…

Several issues associated with equating and interpreting reading test scores from two different measures of achievement are discussed. The discussion is based on an investigation assessing the impact of classroom functional/ability grouping on academic performance of 5,439 special educational students in elementary, middle, and high schools.

The Iowa Tests of Basic Skills were administered to over 600 black and white students in grades six through nine, to determine if the test showed bias against minorities. Outliers were identified from test results. Outliers are items which differ from the central core of test items because they fall outside the range expected from a random…
