The problem with which this investigation is concerned is that of determining the academic as well as psychological differences between the McKinney Texas Job Corps graduates and non-graduates. The purpose of the study is to gain knowledge that will be useful in the guidance of Job Corps students. Nine hypotheses were formulated to investigate the relationship between academic achievement and certain selected academic and psychological variables. It was concluded that significant personality differences do exist among the McKinney Job Corps graduates and non-graduates. Chronological age is a significant variable with respect to success at the Job Corps Center. Academic variables are not useful indicators of success at the Job Corps training program.
