The PISA 2009 Technical Report describes the methodology underlying the PISA 2009 survey. It examines additional features related to the implementation of the project at a level of detail that allows researchers to understand and replicate its analyses. The reader will find a wealth of information on the test and sample design, methodologies used to analyse the data, technical features of the project and quality control mechanisms.



Data Adjudication

This chapter describes the process used to adjudicate the implementation of PISA 2009 in each of the adjudicated entity (i.e. the participating countries, economies and adjudicated regions) and it gives the outcomes of the data adjudication which are mainly based on the following aspects:

  • the extent to which each adjudicated entity met PISA sampling standards;
  • the outcomes of the adaptation, translation and verification process;
  • the outcomes of the national centre and PISA quality monitoring visits;
  • the quality and completeness of the submitted data; and
  • the outcomes of the international coding review.
