Traditionally, the test score represented by the number of items answered correctly was taken as an indicator of the examinee's ability level. Researchers still tend to think that the number-correct score is a way of ordering individuals with respect to the latent trait. The objective of this study is to depict the benefits of using ability…

The reports that teachers receive from the Portland (Oregon) Public Schools Achievement Level Testing Program are planned to help them to see how each individual student is doing, which students need help, and how the class is performing as a whole. The information enables teachers to focus on special needs and problem areas, and also to see an…

Found that scores of MPDs obtained in groups did not differ from MPD scores obtained individually. Results suggest that individual norms may be utilized for scores in the group administration of the MPD, although replication with a larger sample is required to confirm the results. (Author/PC)

Examined the content factors of the GPPT using factor analytic procedures based on item intercorrelations, in contrast to the published version's use of part scores from a prior groupings of items. In terms of what it proposes to measure, it was concluded that the GPPT has very limited utility. (Author/RC)

Twenty-nine deaf children (5-to 15-years old) participated in a study of middle ear impedance and threshold variations in repeated audiograms. (Author/LS)

The booklet was designed to help each recipient of the California Achievement Test (CAT) reports to understand the general format of the reports, the abbreviations and symbols used, and the types of scores presented. It was also intended to assist in interpreting CAT results and using these results at each level of the educational process to best…

Both the attenuation paradox of traditional test theory and the assumption of local independence in person-item response theory have caused problems in interpretation. This paper demonstrates that the two are related concepts, and, through this demonstration, both are clarified. It is demonstrated that the breakdown of local independence leads to…

A study is proposed that seeks to use the normally problematic factor of non-response to a survey in a positive way in order to estimate certain characteristics of a population subgroup. A longitudinal database, the Scientific and Technical Personnel Data System (STPDS) measures the educational, demographic, and employment characteristics of the…

Specific Wechsler Intelligence Scale for Children Revised subtest scores and score relationship of 33 learning disabled (LD) children (6-12 years old) were analyzed by chi square and t tests for significant differences between those LD children displaying behavior problems and those who did not exhibit such problems. Comparison of Similarities,…

Discusses the many implications of test usage, from the employer, employee, state, and legal standpoint. (PG)

The factor structure in this study was remarkably consistent across the age range, with three factors emerging for each group: Verbal Comprehension, Perceptual Organization, and Freedom from Distractibility. The results of the study are discussed in terms of their clinical applications, particularly interpretation of WISC-R profiles. (Author)
