Internet has made the world a real global village that places educational organizations in a very high competitive environment. The educational organizations should improve quality of their services to stakeholders such as students, faculty and future employers to get more competitive advantages over other competitors. Every educational organization, small or big, has the need to make use of the large scale data available and hopefully turn it into a predictive/analytical model that supports decision making process. Data mining is a young interdisciplinary field, the task of discovering interesting patterns/knowledge from large amounts of data stored in database, data warehouse or other information repositories. Through Data Mining we can effectively address the challenges for improving the quality to provide new knowledge related to the educational processes and entities to the managerial system.
