How are countries/economies chosen to participate in PISA?
Countries/economies interested in participating in PISA contact the OECD Secretariat. The PISA Governing Board then approves membership according to certain criteria. Participants must have the technical expertise necessary to administer an international assessment and must be able to meet the full costs of participation. To take part in a cycle of PISA, participants must join two years before the survey takes place. For example, PISA 2012 participants will have joined before March 2010.
