Focusing on program development and evaluation, this document presents the summative evaluation of the community development component of the Mountain-Plains Career Education Model IV, a residential, family-based education program developed to improve the economic potential and lifestyle of selected student families in a six-state area. The report first provides an overview of the community development component, delineates the goals and program objectives, and outlines the stages of component and program development. Next, the evaluation findings are discussed and include measurements made in three program areas: description of leadership behavior, levels of community participation, and evaluation of orientation. Results of the analysis made of the quality of the evaluation instruments are reported as well as the results of the findings. Finally, a summary of the program development and evaluation findings during the stabilization and operation period is presented and formative implications are given. Organizational charts and statistical tables are appended. (For a summative evaluation of the overall Mountain-Plains Program, see CE 014 682-684.) (BM)
