About PIRLS 2011
PIRLS 2011 is the third cycle of Progress in International Reading Literacy Study (PIRLS). Building on the highly successful implementation of its predecessors, PIRLS 2001 and PIRLS 2006, PIRLS 2011 collects data to provide information on trends in reading literacy achievement of fourth-grade students, while providing baseline data for new countries. Combining newly developed reading assessment passages and questions for 2011 with a selection of secure assessment passages and questions from 2001 and 2006, PIRLS 2011 offers a state-of-the-art assessment of reading comprehension that allows measurement of change since 2001, and includes a full complement of questionnaires to investigate the experiences young children have at home and school in learning to read.
