Aptitude test scores have been correlated with grades in twenty-six courses and with overall indices of academic performance, based on over 500 students attending a public high school. There is little evidence of differential validity for the major academic subject areas; instead, five tests (English Vocabulary, Graphoria, Silograms, Analytical…

The aptitude scores of 70 physicians in various areas of practice who were tested between 1934 and 1971 were compared with aptitude battery scores obtained by the general population of Johnson O'Connor Research Foundation examinees. For each aptitude test, obtained-score distributions were produced for the time periods of pre-1941, 1941-45, and…

The correlations of each of the 22 tests in the Johnson O'Connor Research Foundation battery with all other tests in the battery are listed. Four fairly large samples are used, each including cases of one sex and a narrow age range. These cases come from a file of 3,555 examinees tested between June 1981 and the fall of 1982. The purpose of…

As a consequence of a validation study based on over 200 skilled technicians employed in engine manufacturing, seven aptitude tests were administered to 50 applicants in June 1982. This report presents correlations between test scores and three criteria (math grades, job performance ratings, and a composite) for the 26 people who entered the…

A study examined the relationship of aptitudes to the performance of skilled technical jobs in engine manufacturing. During the study, several approaches were utilized, including criterion-referenced validation, taxonomic validation, construct validation, and detailed anlaysis of the behaviors involved in performing the jobs. The study sample…
