Journal Article 2017 01 06 The aim of the study is to determine reference federations in order to benchmarking inefficient federations . Use of management patterns by efficient organization can be effective to create optimal route for efficiency organizations. In   any society efficient organizations effect on the other organizations' performance. So, the first step in the success of this project is the selection of reference organizations.14 selected important, medalist with sporting achievement Federations have been priority choosed . 112 samples were selected through staff, heads and managers of federations to fill in the questionaiers. To determine the validity of the questionnaire,it has been distributed among 11 experts and specialists in the field of sport management then after implementation the comments and suggestions it  was confirmed with 0/92. And to determine the reliability of the questionnaire,it has been distributed among the provintial sport staff and confirmed with 0/81 reliability.  DEA method as a non-parametric and efficient method, first determined efficient and inefficient federations then appointed reference federations for inefficient federations by use of impact coefficient method.Research method was descriptive-analytical and in terms of  purpose is of Practical.To analyse data, MATLAB software was used. The results showed that wrestling, taekwondo and football federations were of efficient , important and references federations for other federations'performance.
