This is the third part of a conversation between Yamini Aiyar and Rahul Mukhopadhyay. It takes Aiyar’s recent book ‘Lessons in State Capacity from Delhi’s Schools’ as a starting point. In this part of the conversation, drawing on Delhi’s school reforms, she reflects on how civil society organizations and education bureaucracies can collaborate more effectively. She highlights the challenges of translating reform ideas into practice and argues for cultivating ‘interstitial spaces’ of dialogue, trust, and sustained engagement to enable meaningful institutional change.
