This article is drawn from examination of a number of training manuals and papers which consider or use ranking methods in PRA. The original use of ranking methods in PRA has become replaced by an increasing reliance upon ranks for decision making. This change in emphasis requires practitioners to be aware of the limitations of ranking so that justifiable decisions can be made. The authors remind readers of how to rank and give guidelines on interpreting ranks.
