The purpose of this article is to clarify the important position of comparative study in formulation and decision making of new educational policy, through critical comparative analysis of the systems of student teacher and teacher appraisement in this country. At first, this article made a critical analysis of the regulations about above mentioned two systems, and pointed out their unreasonable articles. Then by the comparative study of the systems in Germany, United States, Japan and England, we have cleared the exceptional features in these two systems. According to comparative analysis in this article, we discovered that although the teacher education in this country is devoted to imitate the German model, yet it lacks the spirit of German system and its necessary measures. For example, we have not enough teacher centers, as a sesult, it becomes only in name but not in eality. On the other hand, the system of teacher appraisement, has not noly completely disregarded of the experience in other countries, but also never made a careful study about its feasibility. So at last, it becomes difficult to put into practice effectively. At last, on the basis of this study, the researcher suggests three recommenda- tions:1.to give up the German model of student teacher system, and to adopt the USA and Japanese beginning teacher's inservice-study system; 2.to revise the regulations, and stipulate that the committee of teacher appraisement must at least have two times of the combined recruit of teachers every year; 3.in future, before the decision making of new educationall policy, it must have a careful comparative study with other countries.
