We wish to thank our friends and colleagues for their support and advice
in developing and writing this book. We would like to thank Frederick
Seddon and Annette Batchelor for providing excellent reviews and feedback
on the book. We wish to give a special thank you to the young
people and staff who participated in the original research. Without your
views, we would not have been able to capture the challenges and complexity
of measuring social impact in Secure Training Centres.
