The purpose of this study was to determine the relative contribution of the leadership styles of cooperative education directors and organization structural characteristics of the program and institution to cooperative education program outcomes in colleges and universities in the United States. The target population was all cooperative education directors at colleges in the United States--obtained from a mailing list of 397 two-year and 505 four-year institutions that have cooperative education programs. A sample consisting of 15 directors for two-year and 15 for four-year colleges, for each of six geographic regions of the United States was selected and mailed questionnaires; 139 usable questionnaires were returned. Results of the study showed cooperative education directors having a low mean leadership style of consideration score and an average initiating structure score, suggesting that factors outside the study may have resulted in these persons having a perceived leadership style of consideration lower than norms for educational supervisors. There were no linear relationships found significant among leadership style variables and organizational structural variables. Moreover, there were no statistically significant linear relationships among the leadership styles, organization structure, and cooperative education program outcome variables as measured in this study. It was recommended that research be conducted to determine what other variables might account for program outcomes in cooperative education. (KC)
