This Public Service Practicum Curriculum Guide is intended to assist social science and occupational teachers in the areas of public service and related occupations to develop, implement, and operate an internship program. Designed for use in all schools in rural, suburban, or city settings, this guide is based on a program developed in Elk Grove (Illinois) high school district 214. The first of eight sections provides information as to the need for including public service internships in all high school curriculums. Suggestions for developing a public service internship program are included in section two. Section three contains a suggested occupational public service course sequence since the program is designed to be an instructional program with a community experience. Section four contains a brief description of 147 public service occupations, related jobs, recommended high school courses, formal education required, Illinois colleges offering postsecondary programs, outlook for employment, and references for additional information. Section five includes a discussion of instructional methods, teaching units, training plans of career performance objectives, methods of evaluating student competencies, and learning activities. Section six involves evaluation of the practicum and includes evaluation instruments. Section seven provides general information essential to the development and operation of the program. An annotated bibliography of resource materials for both students and teachers appears in the final section. (BM)
