Abstract
Much interest in managerial skills has been generated recently. However, most of the questionnaires on managerial skills have focused on frequency and not competency. Thus, the purpose of this study is to test the psychometric properties of the managerial skill scales of the Survey of Management Practices, which is purported to measure the competency of individuals on eleven managerial skills. Overall, the results suggest that the managerial skill scales of this instrument have the psychometric properties of internal consistency, interrater agreement, construct validity, divergent discriminate validity, and both internal and external criterion validity. Some modifications for improvement are nevertheless suggested.
