The Programme for International Student Assessment gathers skills and knowledge of students worldwide and compares them internationally. PISA is a project of the Organisation for Economic Cooperation and Development (OECD).
On behalf of the standing Conference of the Minister of Education and Cultural Affairs of the Länder in the Federal Republic of Germany (KMK), the national project management for PISA 2015 is managed by the Centre for International Large Scale Assessment (ZIB), located at the Technische Universität München (Munich, Germany). Prof. Dr. Kristina Reiss is responsible for the scientific project management.
The 3 main domains of PISA (Science, Reading and Mathematics) are a key part of lifelong learning. PISA assesses the level of performance of the adolescents, provides information on results of teaching and learning in schools and also demonstrates strains of development in our educational system. In PISA, focus is not set on the accordance of items with the national curricula of the participating countries. What matters here is to record the core competences in different real life tasks that matter in everyday situations. So the concept of literacy that is used in PISA is a functionalistic one: 15-year-old students should apply competences they have (presumably) learned at school in the context of authentic tasks which are a part of our everyday life.
