A study identified alternative models of short-term upgrading and updating training for employed workers in business and industry. In phase 1, a literature review provided the basis for a nine-cell matrix that conceptualized alternative models of industry-based training as a function of the skill level the training addressed and the degree of program development activity. Phase 2 was a series of investigations to ascertain the extent to which these conceptualized alternative models were used by business and industry. The research procedures were a telephone survey of Minnesota Technical Institute extension directors, focus group interviews with five selected extension administrators, a survey of businesses in Minnesota, and formation of an advisory committee. Findings indicated that Minnesota's technical institutes conducted a high degree of industry-based training activity. Most of this training was targeted toward the manufacturing and health care industries. The study found evidence of the use of each conceptualized industry-based model. No "one best model" emerged; each model seemed to meet different needs. Barriers to the delivery of industry-based training as perceived by industry included availability of needed courses, program accessibility, and lack of confidence in instructor skills and abilities.
