The Progress in International Reading Literacy Study (PIRLS) is an initiative of the International Association for the Evaluation of Educational Achievement (IEA). PIRLS coordinators aim to assess reading progress regularly with a view to observing trends in the development of reading literacy in the participating countries. The assessment focuses on 10-year-olds, i.e. students who are in the second year of Elementary Cycle Two. It was conducted in 2001, in 2006 and in 2011.
