The report aims to help education authorities in Norway and other OECD (Organisation for Economic Cooperation and Development) countries to understand the importance of lower secondary education and to find approaches to strengthen this key education level. It provides an overview of the structure of lower secondary education and the main challenges it faces across OECD countries, develops a comparative framework of the key policy levers for success in lower secondary and adapts it to Norway's specific context. The recommendations focus on teacher quality, school success, student pathways and on the process of effective policy implementation. The report is a result of the OECD's efforts to support making reform happen across OECD and partner countries.
