When comparing two tests that measure the same trait, separate comparisons should be made at different levels of the trait. A simple, practical, approximate formula is given for doing this. The adequacy of the approximation is illustrated using data comparing seven nationally known sixth-grade reading tests. (Author/RC)

The consistency by which shared abilities are assessed on three intelligence tests was investigated. Instruments under consideration include: the Wechsler Intelligence Scale for Children-Revised, the Kaufman Assessment Battery for Children, and the Stanford-Binet Intelligence Scale-Fourth Edition. A list of shared abilities and the subtests…

An approximation formula for the standard error of measurement was recently proposed by Garvin. The properties of this approximation to the standard error of measurement are described in this paper and illustrated with hypothetical data. It is concluded that the approximation is a systematic overestimate of the standard error of measurement…

The paper reviews studies (1966-1985) of the intellectual abilities of culturally diverse 4-5 year olds in a discussion of the identification of giftedness in culturally diverse populations. Studies are cited which involved Mexican American, Black, Native American, French Canadian, and Belgian students. The following six topics are addressed: (1)…

Using the personality trait versus state distinction as a substantive context, the fit of the factor analytic model to difference score data is investigated and found to be quite good. Methodological issues related to properties of difference scores and their implications for personality research are briefly discussed. (Author)

The reliability of measures of need for achievement can be improved by increasing the number of items and by using different scoring systems and stimulus materials. (MLP)

Concludes that individuals can consciously introduce false projections while inhibiting true projections, thus affecting the theory of projection and the use of projective techniques for personality assessment. Since projective responses are subject to conscious control and distortion they are not reliable. (Author/EK)

Discusses two papers on university test validity and presents rational standards for researchers working on test validity. (PG)

Four essential dimensions of a performance test are detailed: directness of test method, type of criterion, standardization of conditions, and objectivity of scoring. For simplicity these factors are described as if each were dichotomous, when in actuality each is a continuum; a test method may be more or less direct, conditions more or less…
