The PISA 2003 Technical Report describes the complex methodology underlying PISA 2003, along with additional features related to the implementation of the project at a level of detail that allows researchers to understand and replicate its analyses. It presents information on the test and sample design, methodologies used to analyse the data, technical features of the project and quality control mechanisms.



Coding Reliability Studies

As described in Chapter 2, a substantial proportion of the PISA 2003 items were open ended and required coding by trained personnel. It was important therefore that PISA implemented procedures that maximised the validity and consistency, both within and between countries, of this coding.
