Today organizations need performance assessment to overcome their weak points. The measurement of inefficiency and improving it requires tools which can report performance level based on all inputs and outputs and shows the inefficiencies along with an appropriate improvement pattern. Therefore, data envelopment analysis (DEA) can be used as a useful tool. However, the radial models of DEA ignore the role of slack variables in assessing performance and this results in lack of enough precision in measuring the efficiency of units. Thus, in the present study the efficiency of decision making units was measured regarding slack variables and it has been administered in Payam-e-Nour University. The purpose of present research is to assess performance and measure efficiency of educational departments and besides that, efficient and inefficient units and also efficiency patterns will emerge. The comparison of results with radial model introduces the utilized model more precisely. According to results, organizational improvement is discussed in article.
