Freshmen (N=202) took two batteries of aptitude tests 10 months apart. Six pairs of tests were studied. Two pairs were identical, two were parallel, and two were completely different. This design made it possible to separate three components of practice: (a) general test sophistication, (b) specific practice effect, and (c) item familiarization.…

Changing from the SVIB to the SCII increased the probability of machine-scoring errors. This study examined the accuracy and consistency of SCII profile scores for three commercial scoring agencies. Results indicated improved performance compared with previous studies and suggested that scoring errors should be minimal for the SCII. (Author)

Scores from the Scholastic Aptitude Test and a new test of reading and writing, the California State University and Colleges English Placement Test, were examined to determine if unique properties for either test could be found. Both tests seem to be measuring the same underlying ability with few unique properties. (Author)

The Career Maturity Inventory Attitude Scale materials were found to provide very little useful information concerning the instrument's reliability. The data that were interpretable showed the scale to have quite modest reliability. (Author)

This study provides an analysis and cross-validation of the Strong Vocational Interest Blank (SVIB) occupational introversion-extroversion (OIE) scale, a parent of the IE scale in the Strong-Campbell Interest Inventory (SCII). (Author)

Super's Work Values Inventory is utilized in making interindividual and intraindividual comparative interpretations of work values. Internal consistency reliability coefficients for 15 scales and reliabilities of differences between scores on scales were of such a weak magnitude that caution in making interindividual and intrindividual comparisons…

This article examines the factor structure of two measures of self-concept routinely used with elementary school children: the Coopersmith Self-Esteem Inventory and the Self-Concept and Motivation Inventory. (Author)

Investigated construct validity of four self-report, self-concept instruments: Bledsoe Self-Concept Scale (BSCS), Children's Self-Concept Scale (CSCS), Self-Esteem Inventory (SEI) and Purdue Self-Concept Scale (PSCS). In assessing the self-concepts of 175 fourth-grade children convergent validity of the tests was not established. (Author)

Compared Kuder-Richardson Formula 20 and coefficient alpha (by blocks) reliability estimates for a reading comprehension test. On the average, K-R 20 exceeded coefficient alpha by about .05; that is, K-R 20 exaggerated the internal consistency of the test as would be expected from theory. Implications for counseling interpretations are discussed.…

Differential Aptitude Test (DAT) scores of 2,622 students who were tested in the 8th, 9th, or 10th grades and who later entered a Minnesota area vocational-technical school were analyzed to determine the relationships between test scores and training program entered. Results are presented. (Author)

An increasing number of occupational and educational planning aids are relying on self-estimates of aptitudes rather than objective measures of abilities. A preliminary examination of the accuracy of self-estimated aptitudes with high school seniors (N=74) suggests unsubstantiated self-estimates may lead to decisions based on unrealistic…

Examined the effects on their test performance of junior high school students changing responses. Results indicated that changing answers neither increases the reliability nor decreases the standard error of measurement of the test. (Author/RC)

Holland hypothesized that personality pattern consistency is related to vocational satisfaction, stability, and success. The viability of this key construct in Holland's theory of careers is examined in light of the expected relationship between level of consistency and frequency of occurrence of 2-letter Holland personality codes. Results are…
