This document, which was developed to assist Peace Corps volunteers and those responsible for training them, presents an introductory booklet and six toolkits for use in the training provided to and by volunteers involved in community development. All the materials emphasize long-term participatory approaches to sustainable development and a capacity building framework. The six toolkits each focus on one of the following roles of volunteers: (1) learner; (2) change agent; (3) co-trainer; (4) co-facilitator; (5) project co-planner; and (6) mentor. Each toolkit contains the following items: (1) a knowledge, skills, and attitudes matrix and learning plan; (2) models, concepts, and cases; (3) ideas and activities for practicing the role under discussion; and (4) a list of key resources for additional information and insight. The following are among the types and topics of learning activities presented: community walks; community mapping; shadowing community coaches; gaining local technical knowledge; attending local meetings; keeping a journal; conducting a capacity inventory; communicating to persuade or influence; assessing learners and setting goals; using "decision dots"; using "snow" cards; practicing problem-solving techniques; reaching consensus in a group; finding resources inside communities; identifying locally acceptable ways for communities to raise funds for projects; identifying mentoring resources in communities; active listening; and brainstorming about mentoring links in local communities.
