Tools and Surveys
TI has developed a broad range of practical tools for understanding and combating corruption, ranging from public perception and diagnostic surveys on transparency and corruption to sector-specific corruption studies and practical tools for advancing targeted integrity objectives. This page also offers links to a selection of tools and surveys developed by other leading organizations and experts in the field.
TI Corruption Perceptions Index
The annual TI Corruption Perceptions Index (CPI) ranks more than 180 countries on perceived levels of corruption, based on publicly available opinion surveys.
Bribery Perceptions Index
The Bribe Payers Index (BPI) reflects the perception of the propensity of firms from major exporting nations to bribe abroad.
Global Corruption Barometer
TI’s Global Corruption Barometer (GCB) assesses general public attitudes toward and experience of corruption in dozens of countries around the world.
TI Source Book
The TI Source Book outlines a systematic approach to curbing corruption across all sectors of society. It introduces the concept of the "National Integrity System," providing a framework for analyzing both the causes of corruption and the effectiveness of anti-corruption reform in a given national context. The Source Book takes a comprehensive look at six key areas for reform (leadership, public programs, government organization, law enforcement, public awareness, and anti-corruption institutions), providing detailed overviews of these areas wiith extensive analysis and examples of both successes and failures.
National Integrity System Country Studies
TI’s National Integrity System (NIS) Country Studies are qualitative reports that provide an in-depth assessment of anti-corruption systems at the country level. The studies provide benchmarks for measuring further developments, and a basis for comparing countries.
Corruption Fighter's Toolkit
The Corruption Fighter’s Toolkit is a compendium of practical civil society anti-corruption experiences described in concrete and accessible language. It presents innovative anti-corruption tools developed and implemented by TI national chapters and other civil society organizations from around the world.
Integrity Pacts
TI's Integrity Pact (IP) aims to prevent corruption in public contracting by increasing transparency, prohibiting bribes, external professional monitoring, and sanctions.
