Abstract
In this research, I propose a "power transaction model" that is based on some perspectives and their interventional methods to show the uniqueness and the necessity of school social work practice in Japan. This model focuses upon the power transaction between student and environment, and aims to improve the situation. Assessment consists of understanding the situation, and making clear the student's needs. The interventional methods include advocacy, empowerment, and services coordination. I believe that the mission and the purpose of school social work is to improve student's situation where they are deprived of their rights and opportunities of just and equal school education. And advocacy is the major action to improve the situation. By improving the situation, I believe that the empowerment of the students can be achieved. Therefore, it is important to understand the situation properly, and advocate the student's needs. This paper shows a case study that is based on power transaction model. But, to stress the neccesity of school social work in Japan, this model will have to build a theory, and needs to test its effectiveness.
