This publication describes the OECD PISA 2000 international database. The PISA 2000 database comprises micro-level data on student performance for 32 countries collected in 2000 and processed during the second half of 2000 and 2001, together with students' responses to the questionnaires and the test questions. The first results were released in December 2001 and presented in the publication Knowledge and Skills for Life: First Results of PISA 2000 (OECD, 2001). The purpose of this publication is to provide all the information required to understand the PISA 2000 database and perform analyses in accordance with the complex methodologies used to collect and process the data. It does not provide detailed information regarding these methods but rather directs readers to the publications which cover these aspects. The PISA 2000 database can be downloaded from www.pisa.oecd.org
