In this open access book, leading teacher educators and researchers provide unique insights into the 'great experiment' in ITE in England, including insights from people who were 'in the room' at critical junctures in the process. International researchers also contribute chapters that highlight the distinctive approach England has taken and why it is now an outlier in terms of ITE policy. The chapters show how it is the relationship between the state and the market – the state rejecting the market when it doesn't deliver the required ideological solution – that makes ITE reform in England so interesting and why it is important it is brought to international attention.
