This monograph on career development begins with an examination of the antecedents of present day career initiatives. The evolution of the concepts of career and career development are reviewed and the rethinking and reformulating of these concepts that have occurred since 1900 are examined. The time period from 1900 to 1950 is reviewed as the formative years; the time from 1950 to 1980 as the transition years; and the time from 1980 and beyond as current formulations. Areas discussed include the industrial revolution, social protest and reform, vocational guidance, vocational development, career, and career development. The impact on counselors of this evolution of career development is discussed. The second half of this monograph looks at the career counseling process and discusses how the broader meanings of career and career development that have evolved over the years impact the career counseling process and its use. The document provides a framework of six possible phases of career counseling: (1) establishing the client-counselor relationship and responsibilities; (2) gathering client self-information and environmental information; (3) understanding client information; (4) drawing conclusions and making diagnoses; (5) taking action; and (6) evaluating the impact of intervention. The use of the Life Career Assessment to gather client information is explained. (NB)
