Interventions in Education Systems draws on research conducted in England, Mexico, Singapore and Finland to illuminate reform processes to education systems in a range of contexts, to develop a better understanding of intervention processes and to promote the development of more sophisticated models for reforming education systems. The authors compare policy implementations and interventions in countries with different socio-economic profiles and different levels of development, highlighting how these processes in practice all too frequently are side-tracked and distorted, often unintentionally, by political, economic and social forces.
