This study was submitted in partial fulfillment of the requirements for the M.Ed. degree at Texas Technological College under the supervision of R.A. Berger, 1968.

The test-retest stability of the Hiskey-Nebraska Test of Learning Aptitude (H-NTLA) was examined in a group of 43 hearing impaired children and adolescents. Test-retest correlations for Ss retested after approximately one year, three years, and five years were .79, .85, and .62 respectively. (Author)

The reliability of differences between pretest and posttest measures with intervening experimental treatment can be highly reliable under some conditions. If the error components of pretest and posttest measures are correlated, the classical formula for the reliability of differences underestimates the actual reliability of gains. (Author/CM)

The Bruininks-Oseretsky Test of Motor Proficiency was evaluated to determine test-retest reliability and if there were presensitizing effects at retest for four- to five-year olds. Test reliability was significantly high. No significant test sensitization of the short form to retesting with the short form or subtests was found. (Author/RD)

Two indices for assessing the efficiency of decisions in mastery testing are proposed. The indices are generalizations of the raw agreement index and the kappa index. Empirical examples of these indices are given. (Author/JKS)

A necessary and sufficient condition for a perfectly homogeneous test in the sense of Loevinger is stated and proved. Using this result, a formula for computing the maximum possible KR-20 when the test variance is assumed fixed is presented. A new index of test homogeneity is also presented and discussed. (Author/BW)

Data on the validity, reliability, and internal consistency of the test are presented to show that it can reliably predict the intelligibility of running speech. (Author)

On a multiple-choice test in which each item has k alternative responses, the test taker is permitted to choose any subset which he believes contains the one correct answer. A scoring system is devised. (Author/CTM)

A modification of the method of reciprocal averages for scaling multiple choice data is proposed. The proposed method handles the data in a piecewise fashion and allows for faster convergence to a solution. (Author/JKS)

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)

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.…
