Intended for use by life skills coaches and students, program evaluators, and individuals developing lesson plans and other training materials, this taxonomy includes all of the terminal performance behaviors and corresponding sub-skills required to become and function as a balanced, self-determined person who manages the problems of everyday life through the discriminating use of a repertoire of problem-solving skills. Following a sketch of recent advances in life skills research, the development and applications of the taxonomy are outlined. Next, 222 skills are grouped according to 17 complexes, each of which contains listings of component elementary skills. In the following chapter the 17 complex skills are grouped into the 4 very complex skill categories of human relations, problem solving, critical thinking, and management of personal affairs. Discussed next are management and intervening factors as well as coping skills. Appended to the taxonomy are the hierarchical and cumulative sequencing of the 222 life skills as well as a 34-item bibliography. A complete version of this text in French is attached. (MN)
