Summary
This paper provides an overview of a number of publicly accessible tools to assess a country’s level of corruption or anti-corruption/good governance performance. The tools are based on both qualitative and quantitative country data, and cover corruption perception, anti-corruption and good governance legal and institutional frameworks as well as their implementation. The tools are classified according to the methods they employ.
