A highly skilled population is critical to achieving these goals, which makes creating and maintaining high quality and equitable education systems a vital part of regional development efforts. Results from the Programme for International Student Assessment (PISA) show that learning outcomes in the region have improved over time, but that the improvement has not been equitable. Some students are performing similarly to students from countries in the European Union, while others are lagging further behind. This report, developed in co-operation with the European Commission and UNICEF, analyses PISA data in detail to identify the strengths, challenges and unique features of education systems in the Western Balkans. Drawing upon a rich knowledge base of education policy and practice in the region, it makes recommendations about how systems in the region can improve learning for all students. This report will be of interest to regional policy-makers as well as individuals who wish to learn more about education in the Western Balkans.
