The need for timely, accurate, and locally relevant career information has been escalating. Within the last 15 years, computer-based systems have been developed that put occupational descriptions, labor market information, plus education, training, and financial aid information into formats usable by students and adults in school and nonschool settings. The proliferation of systems marketed competitively, the increasing depth and breadth of information available, plus the sophistication of the guidance aspects of systems have produced a consumer's dream, but also a major dilemma. Selection of a system for a statewide or substate unit that corresponds to the particular needs of the targeted constituency requires thorough knowledge of the prospective users' characteristics, material and human resources available, hardware capacities, software content, and hardware/software compatibility. All of these factors were taken into consideration during the Career Information Delivery System Feasibility Study in Illinois, and the study provides a model for the selection process. (Various computer-based occupational information delivery systems are described in this paper, comparisons are made, and systems selected by various states are discussed.) (Author/KC)
