The relationships were examined between the Ball Aptitude Battery (BAB) and the Comprehensive Ability Battery, Differential Aptitude Tests, and General Aptitude Test Battery. Results showed adequate convergent and discriminant validities for all BAB tests except inductive reasoning, which was factorially complex. (Author/GDC)

Test-retest reliability coefficients for the brief Career Ability Placement Survey and concurrent validity correlations against the Differential Aptitude Tests and the General Aptitude Test Battery are presented for samples of ninth and tenth grade students. (Author/JKS)

Predictive validity of the Differential Aptitude Test (DAT) was investigated by comparing the DAT scores obtained by students in Grade 9 against their achievement in Grade 12 departmental examinations. Results indicated that the DAT has good predictive power and can be used effectively on a selective basis for counseling and predictive purposes in…

This report examines the construct validity of the Ball Aptitude Battery (BAB), a multiple ability test battery designed to measure aptitudes related to successful work behavior. Construct validation has focused attention on the role of psychological theory and on the need to formulate hypotheses that can be examined in the validation process.…

Three multiple-abilities batteries--the Comprehensive Ability Battery, Differential Aptitude Tests, and General Aptitude Test Battery--are briefly discussed, and results of a study involving cross-correlations of the tests in these batteries are presented. (Author/JKS)

Double cross-validation of a test battery against multiple criterion variables found the first general factor accounts for most criterion variance in cross-validated regression weights. Small contributions are made by mechanical/technical and psychomotor factors. It appears a common general factor plays the major role in validity for a range of…

This study investigates the construct validity of profiles of high school students' (n=92) writing competence obtained from tasks designed to be parallel on all dimensions but discourse mode (expository or narrative) and response mode (direct or indirect). (Author/PN)

Separate-sex norms are no longer applicable for the interpretation of aptitude test scores. The Differential Aptitude Tests must adopt combined-sex norms in order to remain as an effective measurement and counseling instrument. (Author)

This study determined the degree to which the Non-Language Test of Verbal Intelligence, developed to measure verbal ability through a nonlanguage medium, could measure verbal intelligence. Correlation with the Differential Aptitude Test-Verbal suggested the existence of some common, as well as some uncommon, factors between the two tests.…

This study was part of a longitudinal research project to establish the validity of the Ball Aptitude Battery (BAB) relative to various academic criteria. The BAB is a multiple ability test battery of specific work skills for use in career counseling. Previous research has demonstrated that adequate validity coefficients exist for both job…

According to a survey report of the Student Guidance Center at the Seoul National University, approximately thirty percent of the freshmen expressed the desire to be transferred to other departments. It was further reported that more than forty percent of them list the unsuitability of their academic departments to their interests and aptitudes as…

The construct validity of three spatial ability tests was assessed by determining the correlation between the test results and student class grades in various subjects for 58 eighth graders enrolled at the Burris Laboratory School, Ball State University (Muncie, Indiana). Results do not strongly support any of the tests evaluated. (SLD)

To improve vocational rehabilitation programs for schizophrenic persons, a project sought to design an effective assessment strategy. Inactive records of schizophrenic clients at New Jersey sheltered workshops were examined to determine validity and reliability of assessment instruments being used. General Aptitude Test Battery (GATB) profiles of…
