Scaling Procedures and Construct Validation of Context Questionnaire Data

The PISA 2003 context questionnaires included numerous items on student characteristics, student family background, student perceptions, school characteristics and school principals’ perceptions. Though some of these questions can be analysed as single items (for example, gender), most questions were designed to measure latent constructs that cannot be observed directly. Here, transformations or scaling procedures are needed to construct meaningful indices.
