In this paper, the school counselors’ skill at evaluating their own effectiveness was discussed in relation to the American school counselor training system. In the United States, training for the evaluation of skills was conducted in graduate schools, and the national standard of school counselors defines the appropriate manner by which to evaluate school counselors. There are differences in the expected roles of school counselors both in Japan and in the United States, since Japanese school counselors were dispatched to deal with increasing bullying and non-attendance at school. Regardless of these differences, there are many aspects that we can learn from the school counseling practices in the United States. In this paper, the comprehensive school counseling theory and system (Gysbers & Henderson, 2000) is discussed in terms of their applicability to the Japanese school counseling system and the training possibilities.
