The document discusses the development of a framework to define key competencies needed for individuals to lead successful lives and contribute to well-functioning societies. It was developed by the OECD through a collaborative, multidisciplinary process. The framework identifies three broad categories of competencies: 1) using tools interactively, 2) interacting in heterogeneous groups, and 3) acting autonomously. It is based on an analysis of the demands modern life places on individuals in a world characterized by change, complexity, and interdependence. The competencies aim to help both individuals and societies achieve their goals.
