This document presents the Work Program 2000 of the European Center for the Development of Vocational Training (CEDEFOP). It is divided into two sections, each of which describes the main aims and expected activities and outcomes of CEDEFOP projects and the activities of its networks in 2000. The first focuses on developing knowledge and expertise which outlines the themes and content of CEDEFOP projects within the four priority themes. Projects are centered around these themes in the medium-term priorities: promoting competence and lifelong learning; facilitating new ways of learning for a changing society; supporting employment and competitiveness; and improving European understanding and transparency. The second section focuses on serving customers, partners, and policymakers and fostering research cooperation. Projects are centered around the following four guidelines: information on vocational education and training; promoting and interpreting research and the identification of innovation; support to meet specific needs of CEDEFOP's partners; and providing forums for debate and links among policymakers, social partners, researchers, and practitioners. Appendixes include medium-term priorities and operational guidelines for 2000-2003; budget outline for 2000; information and communication policy; organizational chart; and cooperation with the European Training Foundation.
