The learning of decision-making (DM) skills and appropriate attitudes is an important objective of career education. This study provides an empirical test of theoretical links between aspects of DM styles and vocational maturity (VM) in adolescence. Approximately 260 Australian students in grades ten and twelve answered questionnaires measuring personality variables; rational, intuitive, and dependent DM styles; and aspects of VM including planning orientation, information-seeking, concern with choice, occupational information, and application of DM principles. Most of the relationships, in the form of partial correlations controlling for verbal ability, expected between DM styles and VM or personality variables were found. Among the relationships expected and supported partially by the study were the following: (1) that individuals with high career maturities would tend to use active rational forms of decision making in most contexts; (2) that individuals with high internal locus of control would use more active rational forms of DM styles; and (3) that students with high achievement motivation would use more active rational forms of decision making. As a result of the study, it was suggested that training in decision making would be a valuable activity to include in the career education curriculum; and that students should be trained in a number of decision-making styles and should practice these skills in various contexts.
