The author describes and assesses the use of matrix-scoring as a participatory evaluation tool. Often used as part of the Participatory Rural Appraisal (PRA) arsenal of tools, here the author applies it specifically to evaluating the performance of the European Community/European Union (EC/EU) in the provision of aid to Ethiopia between 1976 and 1994. He describes the mapping technique, scoring/ranking system, and assesses the strengths and weaknesses of its use in this case (including tables of responses/results).
