Measuring the continuum of literacy skills among adults: Educational testing and the LAMP experience

The field of educational testing has become increasingly important for providing different stakeholders and decision-makers with information. This paper discusses basic standards for methodological approaches used in measuring literacy skills among adults. The authors address the increasing interest in skills measurement, the discourses on how this should be done with scientific integrity and UNESCO's experience regarding the Literacy Assessment and Monitoring Programme (LAMP). The increase in interest is due to the evolving notion of literacy as a continuum. Its recognition in surveys and data collection is ensured in the first commitment in section 11 of the Belém Framework for Action. The discourse on how measurements should be carried out concerns the need to find valid parsimonious approaches, also their relevance in different institutional, cultural and linguistic contexts as well as issues of ownership and sustainability. Finally, UNESCO's experience with LAMP shows how important addressing these different issues is in order to equip countries with an approach that is fit for purpose.
