Researchers who participate in IEA studies have a unique opportunity to work collaboratively with their counterparts from many different countries and disciplinary backgrounds over a period of several years on questions of shared academic interest. Once the data for a given study have been collected and the first round of international reports published, however, opportunities for that kind of collaboration tend to be much less frequent. A major strength of IEA studies compared to other large-scale, international studies is that they are classroom based, thereby making it possible for researchers and policy makers to investigate linkages between students' achievement and a wide range of variables. Those variables could be related to instructional practices, to students' and teachers' background and attitudes, to school organizational patterns, or to opportunity to learn, to name a few. The research questions that TIMSS was designed to address make it clear that these kinds of relational, multi-variate analyses were among the major goals of the project. The international reports of the TIMSS-95 results that were published by the International Study Center at Boston College between 1996 and 1999 were intended to provide comprehensive coverage of the basic findings of the study. They were not intended to provide in-depth analyses of research and policy issues; instead, their main purpose was to make the basic findings of the study widely available in a timely manner. This they certainly did.

The 2015 TIMSS Grade 5 study was administered for the first time in South Africa in August 2015. The study was led by a team of researchers at the Human Sciences Research Council (HSRC) in collaboration with the Department of Basic Education (DBE) and the International Association for the Evaluation of Educational Achievement (IEA). Providing the first, nationally representative, internationally comparative compendium of data on Grade 5 learners in South Africa, the report is a new indicator of the health of our educational system. The analyses describe in detail the current picture of achievement for learners in the country, highlighting key individual, family, school and provincial differences. The results also include key developments concerning preschool attendance, early learning environments, as well as the importance of educational expectations and academic beliefs, and the damaging effects of bullying. The findings highlight the importance of early achievement and the need to understand the multiple layers of influence on educational pathways, with the conclusions and recommendations highlighting an unequal, yet treatable system. The Grade 5 study sits alongside the Grade 9 study which has been carried out in South Africa since 1995, recently completing its fifth round.
