This Technical Companion Report accompanies the Synthesis Report. The report acts as a reference volume for audiences who want to have a more detailed understanding of the methodology and findings of different pieces of research that are synthesised in the Synthesis Report. It is also meant to provide transparency about how the data were collected and the origins of the synthesised findings. Not all research method findings are separately reported in this volume: some are directly integrated in the Synthesis Report, such as the findings of the qualitative school case study research and the findings of the state-level key information interviews to address the relevance and sustainability questions. The methodological details of these research methods are, however, included in the Methodology chapter of this report.
