PISA 2006 Technical Report

The PISA 2006 Technical Report describes the methodology underlying the PISA 2006 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.


Coding and Marker Reliability Studies

As explained in the first section of this report, on test design (see Chapter 2), a substantial proportion of the PISA 2006 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. Each country coded items on the basis of coding guides prepared by the consortium (see Chapter 2) using the design described in Chapter 6. Training sessions to train countries in the use of the coding guides were held prior to both the field trial and the main study.
