Our ground-breaking longitudinal research with 12,000 children growing up in 4 different countries has enabled us to develop new methods and approaches for studies of this kind. 

Our mixed methods approach features a household and child survey, qualitative research and a school survey. Other key features are our cross-disciplinary approach, dual cohort, comparative design, and a holistic analytical model.  For a comprehensive overview of our methods take a look at our Synthesis Report.  You can also find out the lessons we have learned along the way in this reflective report on our Research Methods.  Also click through to the Methodologies theme page and  Methodological Lessons and Learning project page to find out more.
