This keynote address examines the role of the deputy principal and the stress cycle in an educational climate of uncertainty and rapid social and educational change. A profile of the "average" deputy principal is offered, and the term stress is defined. Methods of researching stress are examined. Factors that contribute to stress in school personnel are outlined, including: resources and environment, change and competing demands, meetings, staff, time use, parents, community, networks and relationships, personality and health, and self-development. The paper concludes that people work better under some degree of stress, but this degree varies according to the individual and his or her environment. Attitudes towards stress are important, as well as the development of individualized techniques and skills for managing it. (Contains 12 references.) (JDD)
