The primary purpose of this study was to investigate the relationships which exist between various predictor measures obtained on students while in training at private post-high school trade, technical, and business schools and a particular global definition of vocational success. The data were collected from 518 students who responded to mailed questionnaires, and through a fifth-year follow-up questionnaire. The Pearson product-moment correlation coefficient, multiple regression analysis, and the Eta statistic were used to analyze the data. Specific findings were: (1) In response to questions concerning relationships between various predictor measures and a global criterion of vocational success, no significant relationships were shown for any of the predictor variables for all students combined or for male students, however, five hypotheses were rejected for female business students, and (2) Of the 148 null hypotheses tested, a total of 18 were rejected at the .05 level and 10 of those were among the 37 tested for female business school students. This indicates a sex rather than a type of school factor at work. (Author/GEB)
