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.



Proficiency Scale Construction

The PISA test design makes it possible to use techniques of modern item response modelling (see Chapter 9) to simultaneously estimate the ability of all students taking the PISA assessment, and the difficulty of all PISA items, locating these estimates of student ability and item difficulty on a single continuum.
