Part of a course designed to acquaint high school students with basic information concerning careers in public service, this student guide is one of nine (each with accompaning teacher's manual) which constitute a course entitled "Orientation to Public Service." Focus in the units covered by the guide is on transportation management, one of eight major public service occupational groups included in the course. The student is introduced to the field of transportation management, to the major federal transportation agencies (Federal Aviation Administration, Federal Highway Administration, National Highway Traffic Safety Administration, and Federal Railroad Administration), and to worker functions and duties for jobs available in the various job families: the airways, the highways, and the railways. Contents are divided into several units of reading and related activities, some designed for completion independently, some by groups. (The accompanying teacher's manual is CE 013 662. The course is the first of a series of three developed as a comprehensive approach to vocational skill development in public service for Georgia high schools. Also available is a guide for the total program, Applied Program of Public Service, CE 013 652.) (JT)
