Since the 1980s there has been significant reform in the development, delivery, and evaluation of all areas of public policy and services provision, including schooling. The reforms are prompted by a general “turn” from direct government determination and provision of public services to indirect governance undertaken by a mixture of public, private, and philanthropic actors. Orthodoxies about public sector governance and schooling system reform have shifted over this time from a preference for bureaucracy to preferences for markets, contracts, and most recently social networks. Schooling system governance in many Organisation for Economic Co-operation and Development (OECD) countries has seen devolution of substantial statutory powers, responsibilities, and accountabilities to local parent communities or shared-interest coalitions, both for-profit and not-for-profit. Schooling policy, governance, and services provision work is now distributed across multiple state, parastatal, and nongovernmental actors. Trust in the actions of others within devolved and distributed systems is identified as an essential social lubricant of contemporary schooling governance and reform. Studies of the role played by trust in schooling systems remain relatively rare.
