Two lower bounds to reliability in classical test theory, Guttman's lamda and Cronbach's alpha, are shown to be terms of an infinite series of lower bounds. All terms of this series are equal to reliability if and only if the test contains items which are tau-equivalent. (Author/JKS)

Simulated data based on five test score distributions indicate that a slight modification of the asymptotic normal theory for the estimation of the p and kappa indices in mastery testing will provide results which are in close agreement with those based on small samples from the beta-binomial distribution. (Author/BW)

The reliability and validity of essay scoring were investigated by comparing the mean scores assigned to good and poor quality essay responses of different lengths. Long responses had a significantly higher mean than responses of short or moderate length. Good quality responses were graded significantly higher than poor quality responses. (Author)

Data showed high reliability for all nine syntactic structures and total screen scores. Reliability remained high when results were examined for different hearing loss categories. There was a significant decrease in scores across these hearing loss categories but a marked increase in the discriminating power of the screens. (Author/CL)

Aims to help instructors make more valid test questions, particularly multiple-choice ones. Emphasis is placed on multiple-choice questions to show the wealth of opportunities they offer for testing because of their uses, objectivity, and ease of grading. Discusses test scheduling, construction, and evaluation and follow-up. (CT)

An alternative derivation was given of Gaylord's formulas showing the relationships among the average item intercorrelation, the average item-test correlation, and test reliability. Certain parallels were also noted in analysis of variance and principal component analysis. (Author)

Reliability maximizing weights are related to theoretically specified true score scaling weights to show a constant relationship that is invariant under separate linear tranformations on each variable in the system. Test theoretic relations should be derived for the most general model available and not for unnecessarily constrained models.…

The use of Bayes' estimates for proportions in the Law of Comparative Judgment is suggested to avoid sample proportions of zero and one. (Author)

The dependence of reliability indices for mastery tests on mean and cutoff scores was examined in the case of three decision-theoretic indices. Dependence of kappa on mean and cutoff scores was opposite to that of the proportion of correct decisions, which was linearly related to average threshold loss. (Author/BW)

Examines the kind of analysis performed for material on the job prospects in the Occupational Outlook Handbook and evaluates the accuracy of previous projections. Discusses why projections of job outlook are made, methods used in their development, and their accuracy. (JOW)

This paper reports a test-retest study of the Junior Eysenck Personality Inventory for 257 children, ages 7-16, receiving psychological services in a British Columbia public health facility. Findings support the test author's claims over a 30-day period of relative score stability on extraversion and neuroticism. (Author/SJL)

Clarifies three basic causes of the success of human resource development functions from an internal marketing perspective. They are functions actively rendering services in the right "client segments" of their organization; functions doing a few important tasks well; and doing those right things consistently. (CT)

A variety of methodological and statistical problems in the Roffe and Bryant study of the McCarthy Scales' profile reliability are pointed out. Alternative procedures and more efficacious use of the Roffe and Bryant data are suggested. (Author)

The procedures yielding confidence intervals for maximized alpha coefficients of Joe and Woodward are reviewed. Confidence interval procedures of Whalen and Masson are next reviewed. Results are then presented of a Monte Carlo investigation of the procedures. (Author/CTM)

The article is a response to R. Maggiore's article "Reliability of Proposed Short Form of Illinois Test of Psycholinguistic Abilities (ITPA)." The authors present evidence to rebut Maggiore's essentially negative conclusions regarding the reliability of the short form test. (For original paper, see EJ 194 153.) (Author/PHR)
