This report spells out the educational needs and criteria in the overall transportation systems field, offering guidelines for the educational community to help renew or develop careers in the changing transportation systems professions. Intended to allow for career mobility for those already employed in transportation, the comprehensive interdisciplinary guidelines cover the development, operation, and management of the transportation environment. The suggested programs are divided into three levels: (1) beginning-entry, (2) intermediate, and (3) semi-professional. Each core program has been made flexible enough to construct instructional units or modules of educational elements of specific skills, knowledge, and concepts, while simultaneously being geared toward vocational preparation. These core guidelines for curriculum development in intermodal transportation career education are applicable at the secondary and post-secondary levels. (Author/AG)
