The OECD Programme for International Student Assessment's (PISA) 2003 survey collected data on students' performances in reading, mathematics, science and problem solving, as well as contextual information on students' background, home characteristics and school factors which could influence performance. The first results were released in December 2004 and presented in two volumes: Learning for Tomorrow's World - First Results from PISA 2003 (OECD, 2004) and Problem Solving for Tomorrow's World - First Measures of Cross-Curricular Competencies from PISA 2003 (OECD, 2005).
