Alternate versions of Hutchinson's theory were compared, and one which implies the existence of partial knowledge was found to be better than one which implies that an appropriate measure of ability is obtained by applying the conventional correction for guessing. (Author/PN)

Questions that parents, students, and teachers have frequently asked about the meaning of grade equivalent scores are answered, and implications for gifted students are considered. Facts concerning achievement test scores, content, and the norm group are indicated. (SEW)

Current scoring procedures depend on unrealistic assumptions about subjects' performance on the rod-and-frame test. A procedure is presented which corrects for constant error, is sensitive to response strategy and consistency, and examines qualitative and quantitative aspects of performance and individual differences in laterality bias as defined…

Comments upon a 1981 article by Alexander, Pallas, and Cook. Discusses whether particular standardized tests measure achievement or ability and the implications of this issue for school effects research. (GC)

Examined utility of tests for predicting academic achievement of impulsive and reflective first graders. Analyses revealed that for three of the five criterion variables, the optimal equations for predicting the achievement scores differed for impulsives and reflectives. With the same predictor scores, predicted achievement of impulsive and…

A factor analysis was performed for two levels of the Iowa Tests of Basic Skills (ITBS). Results showed that there was essentially one common factor with little evidence that the user would gain much nonredundant information from the 15 scores yielded by the ITBS. (Author/GK)

Performed a factor analysis on the results of the Wechsler Memory Scale for 99 older males to determine how normally aging older adults perform. Results seem to indicate that the manner of functioning in later life becomes deficient in quality rather than in quantitative performance. (Author)

A method for incorporating decline over time of the predictive validity of scores into mental test theory is presented. The procedure utilizes concepts from multiple regression and analysis of repeated measures. (JKS)

Describes types of tests, types of student responses required, ways to interpret tests, and the major test developers. (WD)

Two-point and three-point methods of classifying Minnesota Multiphasic Personality Inventory (MMPI) profiles were compared using 174 students who sought psychological treatment at a student mental health clinic and who generated MMPI profiles with scales 2.7, and 8 as their highest evaluations. Behavioral correlates were determined. (Author/GDC)

Higher mean IQ scores were obtained on the Wechsler Intelligence Scale for Children (WISC) compared to the revised version (WISC-R). The WISC-R had a facilitative effect on the WISC that did not appear when the WISC was administered first. Differences in instructions may have enhanced the practice effect. (Author/JAC)

Describes interpretation technique for providing detailed feedback to students about their performance on the Iowa Tests of Basic Skills. Students summarize their own performance on each major skill. The practical aspects of understanding the full use of routinely collected data make the approach desirable. (Author)

This chapter discusses units of measurement, relates types of scales and norms to the purpose for testing, looks at types of test data typically reported, identifies the primary users of test information, looks at limitations of scales and norms, and looks at the interaction between user and data. (Author/RL)

Presented are normative data, collected on an unselected sample of 302 seven- and nine-year-old children, for the Missouri Children's Behavior Checklist. The potential usefulness of the checklist as an aid in making important clinical decisions is discussed, as is the need for more extensive normative data. (Editor/SJL)
