Tested the factor structure of the McCarthy Scales of Children's Abilities in preschool children (N=141). Found existence of Verbal factor and other Perceptual-Performance factor was confirmed and the Quantitative and Memory factors appear undifferentiated. Found subtests which make up the Motor scale do not constitute a single factor. (Author/ABL)

Administered McCarthy Scales of Children's Abilities to preschool children of normal intelligence with (n=25) and without (n=25) speech/language disorders. Speech/language disorders group had significantly lower scores on all scales except Motor; showed difficulty in short-term auditory memory skills but not in visual memory skills; and had…

Describes the development and preliminary analysis of the Stanford Education Program for Gifted Youth Mathematical Aptitude Test (SEMAT), a math test targeted for high-mathematical-ability elementary school students. Reports that SEMAT discriminated students in the few top percentiles. Contains 14 references. (Author/ASK)

A larger canonical correlation of Self-Directed Search scores with those from the Ball Aptitude Battery for 198 high school students was found compared to results from a 1977 study being replicated. Only modest overlap between the Self Directed Search and the Ball Aptitude Battery was found. (SK)

This article describes the formulation and execution of the Rainbow Project, Phase I, funded by the College Board. Past data suggest that the SAT is a good predictor of performance in college. But in terms of the amount of variance explained by the SAT, there is room for improvement, as there would be for virtually any single test battery. Phase I…

Although academic ability is the most important explanatory variable in studies of student learning, researchers control for it with a wide array and combinations of proxies. The authors investigated how the proxy choice affects estimates of undergraduate student learning by testing over 150 specifications of a single model, each including a…

The present research investigated the relations among the measured and the expressed career decision-making difficulties in a sample of 299 young adults who intended to apply to college or university. As hypothesised, the correlations between career decision-making difficulties, as measured by the Career Decision-Making Difficulties Questionnaire…

Medicine is a profession with a long history of research and high standards of methodological rigour and evidence-based decision making. These standards are being transferred into medical education. Universities are starting to collect high-quality data on their admissions systems. This has not been a short-term proposition. Medical courses are…

Factor analyses of the McCarthy Scales were performed on separate groups of black and white children to assess the comparability of the underlying structures and to evaluate the construct validity of the MSCA for each racial group. There was evidence of the instrument's construct validity for each racial group. (Author)

The purpose of this study was to assess the effects of correlated dimensions and differential ability on one dimension on parameter estimation when using a two-dimensional item response theory model. Multidimensional analysis of simulated two-dimensional item response data fitting the M2PL model of M. D. Reckase (1985, 1986) was conducted using…

A study of children enrolled in a year-round preschool program for the "culturally disadvantaged" in Tampa, Florida revealed that children with defective vision performed more poorly on both the Peabody Picture Vocabulary Test and Metropolitan Readiness Test. (Author/JM)

The study involving 614 hearing impaired students investigated the adequacy of time limits currently followed in the administration of two subtests of the Differential Aptitude Test battery when used with young deaf students. Thirty-six students who did not complete the Space Relations portion of the battery under the timed condition, and 11 who…

As test standards and research literature in general indicate, definitions of test bias and item bias vary considerably, as do the results of existing methods of identifying biased items. The situation is further complicated by issues of content, context, construct, and criterion. In achievement tests, for example, content validity may impose…
