The ability of the Slosson Intelligence Test to predict academic achievement was assessed by using three samples of pre-kindergarten pupils from three successive years in a large midwest school district. Results indicate a moderately good predictive power of the instrument. (Author/JKS)

The relationships between egocentrism and certain socialization variables were examined for a sample of first through fifth grade rural children. The most significant results were the high correlations of egocentrism scores, sociometric scores, and teachers' ratings of popularity with observed playground behavior. (Author/JKS)

Reliability and validity data on the Personal Attribute Inventory for Children (PAIC) are reported. The inventory correlated with the Piers-Harris Children's Self-Concept Scale at .32 and had a test-retest reliability of .88 over a four-week span. Different PAIC results were obtained for eighth grade students. (JKS)

Two Groups of educable mentally retarded primary and secondary pupils were compared on measures of self-esteem and intelligence to determine whether scores on a self-drawing test and those on a self-perception test were related. A significant correlation was found for the secondary pupils only. (Author/JKS)

A scale measuring attitudes toward small-group teaching was administered to 442 teachers from 28 elementary and secondary schools in Israel. At least two dimensions of attitudes were identified: control over class and efficiency of the method. (Author/JKS)

The PM statistical index, which indicates the probability that a person will belong to a particular clinical class, is described. The coefficient is similar to the G index but is easier to compute. An empirical example is presented. (JKS)

The Sixteen Personality Factor Questionnaire, Gordon Personal Profile, and Gordon Personal Inventory were administered to 151 male and female high school students. Multiple regression analysis indicated that the personality scales of each test could be predicted from the scales of the other tests. (Author/JKS)

A problem of considerable importance in certain educational settings is determining how many items to include on a mastery test. Applying ranking and selection procedures, a solution is given which includes as a special case all existing single-stage, non-Bayesian solutions based on a strong true-score model. (Author/JKS)

The G index is a measure of similarity between pairs of dichotomized items. The G index is generalized here to the case where items are trichotomized. (JKS)

It is shown how partial covariance, part and partial correlation, and regression weights can be estimated and tested for significance by means of a factor analytic model. Comparable partial covariance, correlations, and regression weights have identical significance tests. (Author)

A problem in analysis of variance is that after rejection of the overall hypothesis, no contrasts of interest are found to be significant. A procedure for determining the contrast of significance is outlined, and the relationship between the "most significant" contrast and the overall test is shown. (Author/JKS)

A simple rationale for Scheffe's Method and Gabriel's Simultaneous Test Procedure is presented. Examples of both methods are provided. (Author)

The effect of stratified sampling of items based on item difficulty and/or interitem correlations on the estimation of test score distribution parameters using multiple matrix sampling was studied. Results indicated that stratification did not consistently improve the stability of parameter estimation. (Author/JKS)

The development of the Estimate of Self-Competence Scale is described. The instrument was designed to measure generalized expectancy of task success. Reliability and validity data are provided. (Author/JKS)

The Edwards Personal Preference Schedule was administered to three samples rural high school students. Distributions of scores were similar to Edwards' college sample, except in the area of sex differences. (JKS)
