This document discusses methods for measuring corruption in education systems, specifically in Eastern Europe and Central Asia. It summarizes quantitative survey techniques including Public Expenditure Tracking Surveys (PETS) to identify leakages in education funding, Quantitative Service Delivery Surveys (QSDS) to examine efficiency and quality of service delivery, and report cards to gather user perceptions of education quality and accountability. The document advocates combining these different survey methods and data sources like household surveys and tests to get a comprehensive diagnosis of education systems and identify areas vulnerable to corruption.
