This booklet deals with the issue of corruption in the education sector. How can we define corruption in education? How can we assess the magnitude of malpractices in the sector? How can we improve transparency and accountability in each of the domains of educational planning and management (such as financing, public procurement, teacher management, and examinations)? This booklet addresses these questions in order to help countries develop more appropriate strategies to detect, reduce, and control corrupt practices, thus contributing to more efficient and equitable education systems.
