One in a series devoted to the topic of careers in transportation, this guide, which is intended to aid in curriculum development for transportation career education in elementary through high school, provides information and models for career education and the transportation field. The four sections that comprise the guide are the following: (1) career education, reviewing its goals and four phases: career awareness, orientation, exploration, and preparation; (2) transportation, discussing its development, governmental involvement, and four major types: land, water, aerospace, and pipelines; (3) the transportation career education cluster, which fuses career education with the concepts of intermodal transportation careers (careers which contain job elements of more than one mode of transportation) and includes twelve major occupational groups and sixty-one job families; and (4) an in-depth analysis of the twelve transportation occupational groups. The twelve career service areas consist of data management, distribution, environmental protection maintenance, management, marketing, passenger services regulatory agencies, safety and security, systems planning, vehicle operation, and vehicle support. For each, section IV provides a definition, task analysis, core curriculum elements, career ladders, and recommended related courses. (ELG)
