Measuring literacy in IALS: a construct-centered approach

This paper offers a brief overview of the framework that has been used for developing the tasks used to measure literacy in IALS as well as for understanding the meaning of what is being reported with respect to the comparative literacy proficiencies of adults. The importance of developing a framework is thought to be central in construct-based approaches to measurement. Among the things that should be included in the framework are an agreed definition of what ought to be measured and the identification of characteristics that can be used in the construction and interpretation of these tasks.
