Abstract
The number of ranking and league table systems has increased rapidly in recent years across many nations. However, little cross-national analysis of the strengths and weaknesses of various approaches has been conducted. To accomplish such a task, a framework or typology that describes the individual ranking systems is needed. This article presents the summary principles from the first-ever international meeting on these issues, held from 13 to 15 June 2002, in Warsaw, Poland. These principles will be of assistance in future discussions about the different benefits and limitations of ranking and league table systems.
