This document is one in a set of eight staff development training manuals developed to facilitate the efforts of educators in the planning and implementation of comprehensive career guidance programs on the secondary level (7-12). This series is based on the goals and developmental objectives identified by the Georgia Comprehensive Career Guidance Project. (See CE 018 130 for the final report of this project). The introduction of each manual outlines these goals and objectives under the following three domains: interpersonal effectiveness; work and life skills; and life career planning. The fifteen activities presented in this manual on self validation encourage maximum participant involvement and small group experiences. These activities relate to the students' quest for independence, identity, and confidence. More specifically, these activities are designed to help guidance team members learn more about particular psychological concepts and principles which facilitate student understanding of "self" as well as understanding of interactions with others. (The other seven staff development guides are available under ERIC CE 018 147, CE 018 150, CE 018 152, CE 018 154, CE 018 158, CE 018 161, and CE 018 163.) (BM)
