EARC successfully handled the data management aspect of the project for both the field work in 2002, 2006, 2010 and the main survey in 2003, 2007, and 2011. EARC data managers were responsible for preparing the data base using WinDEM, WinLINK and WinWS3 software Packages. A completed cleaned data was sent to the international Study Centre (ICS), Boston College and Data processing Centre, Hamburg for analysis.
The Trends in International Mathematics and Science Study (TIMSS) is a series of international assessments of the mathematics and science knowledge of students around the world. The International Association for Evaluation of Educational Assessments (IEA) based in Amsterdam organizes the Trends in International Mathematics and Science Study (TIMSS) with the International Study Center (ISC) at Boston College USA.
TIMSS measures trends in mathematics and science achievement at the fourth and eighth grades in participating countries around the world, as well as monitoring curricular implementation and identifies promising instructional practices. Ghana’s TIMSS was organized for only eighth grade students. The Study allows educational systems to compare students' educational achievement and learn from the experiences of others in designing effective education policy. This study was first conducted in 1995, and has been performed every 4 years thereafter.
