                  As a manager of Vivekdhammaprasithvidya School, an abbot of Wat That, and the Ecclesiastical Provincial Governor of Khonkaen province, Phra Dhammavisudthacarya (Sumanamahathera) and Phratepkittirangsi (Thongsa Varalābho) run effectively the Buddhist educational administration and management of Dhamma-Pali and general education at Wat That. From the past to the present, a director of the Vivekdhammaprasithvidya School was given a great duty to be responsible for the Dhamma-Pali and general education. Many director assistants in various sections were also given a great duty to help a director to achieve all given purposes. In the Dhamma-Pali section, there were the learned teachers of every subject. These teachers were given a proper salary and they were asked to participate in the Buddhist ecclesiastical teacher-training project by the Buddhist Order in order to achieve the quality of a learning-and-teaching process. Students and teachers were supported with four facilities: food, clothes, medicine, and living places. Students were given the scholarship if they passed the Order’s Pali examination. Here, people congratulated students in the cerebration ceremony. The school prepared all kinds of the learning-and-teaching equipment enough and supported children and youths to go into the Order. It also supports all children and youths to study at Vivekdhammaprasithvidya School after the end of the second semester for every year.

                  The achievement factor of Buddhist educational administration and management at the Vivekdhammaprasithvidya School, Wat That came from the quality of Buddhist educational administration and management by all executives. A belief and a credit to the Vivekdhammaprasithvidya School as a well-known educational institution that had many renowned alumni from the past to the present motivated many students to learn there. Because the school was established in the municipality of the Khonkaen province, it was comfortable to come and go back. There were many types of educational equipment in the school. Parents believed felt that the ecclesiastical life was very useful and valuable. They allowed their children to go into the Order and study at this school because they believed that all ordained children were instructed both in the Dhamma-Pali and general education.   

            Children who finished education from the Vivekdhammaprasithvidya School at Wat That got the ecclesiastical and general knowledge according to the Threefold Training. They became a good member of a family and a society. If they were continuous to get the monkshood, they would be the good member of the Buddhist Order. In this educational administration and management, the Vivekdhammaprasithvidya School could make novices and children a learned person with moral life till they got admissions to ecclesiastical, governmental and private universities for every year.
