The first computer-assisted career planning systems were developed in the late 1960s and were based soundly on the best of career development and decision-making theory. Over the years, this tradition has continued as the technology that delivers these systems' content has improved dramatically and as they have been universally accepted as…

Notions of career path recycling, development in reverse, nonlinear progress, and parallel streams in career development are explored. Suggestions are made for…

Frank Parsons was not the 1st American to recognize or address the need for vocational guidance. Why he, rather than his predecessors, is credited with initiating the field can be attributed to the largely overlooked contributions of 3 other persons: Pauline Agassiz Shaw, Meyer Bloomfield, and Ralph Albertson. The author calls attention to the…
