This publication focuses on a conceptual and research-oriented analysis of the broader issues related to the transition to adulthood. The introduction discusses the societal changes in the highly industrialized countries since World War II which have extensive consequences for youth. The concept of youth as a stage and a lifestyle falling between adolescence and adulthood is explored along with the implications of the concept for the industrial nations. Part I of the report presents an interdisciplinary, descriptive overview of changing concepts and viewpoints relating to the transition to adulthood. The implications of these changes for schooling and on the economy and the labor market are discussed. Part II of the report explores the current relationships and changes among the three major institutions of work, family, and school as they affect the transition to adulthood. The third and final part of the report identifies a number of possible policy responses, within and outside of education, to the problems analyzed in the first sections. This section also identifies areas where further research is needed. Reference notes and a four-page bibliography conclude the report. (MCF)
