To maintain credibility, vocational teachers must be exposed to advanced technology in ways consistent with its use in their occupational specialty area, as well as contemporary techniques for using it in the delivery of instruction. The technical and teaching skills and knowledge of Indiana's vocational teachers must be continually upgraded. Change must be presented in the following contexts: the changing workplace, changes in education, the changing learner, changes in teacher responsibilities, and professional development concerns. A series of competency-based modules have been developed for vocational education teachers. They cover the general competencies teachers must learn to function effectively. Kansas, Alabama, and Michigan have developed statewide systems for professional development of teachers in the area of technology education. Some businesses and industries have also undertaken initiatives to further an understanding of advancements in occupational technologies and the use of technology in the classroom. They include Tandy Corporation/Radio Shack, Cummins Engine Company, Otis Elevator, Westinghouse, and Rogers Building Group. Mentorships have also been used as an innovative way of updating teachers' knowledge of their field of study. Individual teachers have also recognized specific needs and initiated their own programs.
