TIMSS & PIRLS International Study Center

The Trends in International Mathematics and Scirence Study (TIMSS) and Progress in International Reading Literacy Study (PIRLS) International Study Center is dedicated to conducting comparative studies in educational achievement. First conducted in 1995, TIMSS reports every four years on the achievement of fourth and eighth grade students. Fifty countries participated in TIMSS 2007, and more than 60 are expected to take part in TIMSS 2011. A number of countries participating in TIMSS 2011 will have trend data across assessments from 1995 to 2011.

PIRLS collects data to provide information on trends in reading literacy achievement of fourth-grade students, while providing baseline data for new countries. It 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.

Data can be analysed online by a tool developed by the American Institutes for Research (AIR) - AIR Lighthouse. This allows users to ask their own questions of complex datasets without specialized research or statistical skills. Users can create custom-run tables, graphs and other statistics over the Internet. This product is designed to integrate multiple complex surveys, assessments, or other data collections.
