Sustainable School Transformation: An Inside-Out School Led Approach explores how we can best build a truly world class education system. It presents a theoretical and practical case for an alternative approach that combines the rigour of traditional 'top-down' accountability models with the engagement and buy-in of school led 'inside-out' approaches - a combination which can be applied to any school in any context internationally. David Crossley and a range of practitioners and academics draw on their extensive experience of past approaches to school improvement in the UK and US. Rather than reject 'top-down' accountability models, they explore new ways of developing them alongside 'inside-out' school led approaches that really do motivate those in our schools who in the final analysis have to deliver the aspirations of politicians and our wider societies for all our young people. The book is based on the premise that Peter Drucker's notion of addictive achievement, discussed in relation to students in Post Capitalist Society, applies to staff and schools too, and if we want to build a truly world class system it will only be achieved through the motivation and resultant efforts of all those in our schools.
