Changing careers during adulthood has been recognized only recently as a natural part of the development of adult life. A study estimated that 36 percent of all Americans are in some stage of the career transition process. Career changes are becoming increasingly common for women, for workers whose skills have become obsolete, for individuals experiencing a shift in values, and for older workers. Reasons for career changes are either internal or external. Internal or psychological factors are related to changes in individuals or their families. External factors are often related to economic or technological changes in the environment and the work place. Many adults have trouble making career transitions due to: (1) lack of motivation; (2) lack of access to information about alternative careers and opportunities; (3) a narrow idea of available jobs; (4) limited education/training; (5) lack of funds; and (6) lack of counseling. A variety of educational and support services can be provided to help overcome these problems. These services can be delivered effectively through comprehensive guidance centers, residential programs, and brokering services (resource and referral services). This fact sheet includes a bibliography of four resources, most of which are available from the Educational Resources Information Center (ERIC) system. (DC)
