Campbell Leadership Descriptor Participant Workbook & Survey [PDF ebook] 

Before you can help others develop their leadership skills and abilities, you must first help them to recognize strengths and identify areas in which they need to improve. The Campbell Leadership Descriptor was developed to achieve just that. Designed specifically for use in those situations where comprehensive analysis of leadership characteristics is useful — such as leadership seminars, classroom discussions, and one-on-one coaching. The workbook’s self-scored assessment allows you to produce your own profile on the spot… and shows how your self-profile compares with other leaders you have known. It also includes questions to help you evaluate the implications of your scores and how to use that information to develop your own action plan for improvement.
