The guide is one section of a resource kit designed to assist Peace Corps language instruction coordinators in countries around the world in understanding the principles underlying second language learning and teaching and in organizing instructional programs. This section focuses on design and development of pre-service language training programs for the overseas post. An introductory chapter gives an overview of the guide's content and offers suggestions for identifying Pre-Service Training (PST) development needs for the post and for scheduling language coordinator tasks during PST. Subsequent chapters discuss: pre-PST planning and preparation, including a planning checklist and supply list; PST design and implementation, including establishment of goals, descriptions, and schedules, organizing lesson plans, integration of language training with other components and sectors, teaching multiple languages in a multilingual context, grouping trainees for instruction, encouraging independent language learning, allowing for trainee preferences, using the community (community contact activities, village homestays, site visits) for language training, incorporating new training models such as community based PST, and selecting training activities; ensuring ongoing evaluation during PST; and writing post-PST final reports.
