This guide, which includes an outline of 222 hours of technical training integrated with training in community organization techniques, is intended for trainers who prepare Peace Corps water and sanitation technicians and engineers for field service. The training program developed by the guide covers these subject areas: community development, project management, general construction, environmental sanitation, and water resource development. The introduction explains the document and the responsibilities of trainers. Subject-matter areas, the session(s) in which each is taught, and the number of training hours spent on each area are listed. Program goals and behavioral objectives for each subject-matter area are listed, and a suggested block schedule for the training sessions appears. Most of the document consists of the lesson plans for 44 training sessions. The lesson plan for each session consists of information on time, behavioral objectives, printed resources, necessary materials, number of facilitators or trainers, step-by-step procedures to be implemented, and tips for the trainers for successful completion of the session. Suggested ancillary information for the trainer (such as information to be conveyed by a lecture) is provided. Two assessment instruments, "Session Assessment" and "Critique Sheet for Trainers Using This Manual," appear in the guide, along with a list of 14 recommended textbooks and a 22-item bibliography.
