Performance Evaluation is important to manage an Educational Organization. It can help to survey the current situation to make a better one in future. DEA (Data Envelopment Analysis) is a model for ranking Decision Making Units, which uses some inputs and outputs. If our knowledge about the inputs or outputs is not complete or accurate, it will be better to use Grey numbers. In this paper we use Grey DEA to rank the Decision Making Units and evaluate their performances. Part 1 is introduction, part 2 is literature review, in part 3 we present the method, part 4 is numerical Example and the last part is conclusion.
