The purpose of the study was to develop a revision of the logical reasoning section of the California Test of Mental Maturity which increases its discriminative ability while maintaining an acceptable measure of reliability. Subjects were 102 students of general psychology classes at North Texas State University. All were administered the Logical Reasoning section of the California Test of Mental Maturity in its original form and an experimental revision of it (LRTR). The Wesman Personnel Classification Test was administered at the same time to demonstrate the tests' construct validity. Pearson product-moment correlations, item and homogeneity analyses were run. Results indicated that the revised test correlated significantly with the original test and the WPCT. Internal validity of the revised test was satisfactory, showing an improvement over the original test in terms of clarity, reliability and homogeneity.

This problem is two-fold: first, to determine the relationships between the traditional school marks and the test scores made by the Cleburne High School students on the California Test of Mental Maturity as a means of estimating the academic achievement students probably will attain in particular school subjects; second, to determine whether or not such relationships are of sufficient significance that their use will reduce student failures in Cleburne High School.

The problem of this study was to find ways of improving and enriching the curriculum through the use of the intelligence quotients obtained from the California Test of Mental Maturity. To reveal some of the needs of the curriculum and also to reveal the possibilities and limitations of testing for intelligence, statistical relationships between intelligence quotients and academic achievement as measured by both teacher marks and achievement tests were determined.

This study was undertaken in the belief that a greater relationship would be revealed between the Rorschach and intelligence test scores if the factors in the Rorschach which have been found in the past to be related to intelligence could be compared as a whole with scores obtained on mental tests. The purpose of this study was to determine whether it could be demonstrated that a higher degree of relationship does exist between several of the Rorschach factors, considered as a whole, and intelligence as revealed by the California Test of Mental Maturity.
