South Africa has participated in a number of local and international achievement studies in the field of education over the last 20 years and responses to the results have been somewhat mixed. Critics argue that participation in international assessments is a pointless exercise because of the slow pace of improvement in South African education. Supporters point out that international assessment results can be useful at many different levels of policy and planning, especially when studies are repeated across time. The purpose of this book is to provide a measured assessment of what has been achieved in South African education over the last 20 years based on the evidence provided by Trends in International Mathematics and Science Studies (TIMMS), to redefine what 'good' progress means in light of South Africa's developmental pathway and to recommend what evidence based interventions can be considered as the next realistic steps in South Africa's educational development.
