The main purpose of this study was to explore the effectiveness of evaluating student-teachers' teaching skills by self-evaluation and evaluations by the junior and senior high school teachers who supervised them, as a part of the evaluation system of the Teacher Certification Program. In the first survey, 211 student-teachers and the same number of school teachers responded to 32 teaching behaviour evaluation items using a 5-point scale. Factor analysis resulted in the extraction of five factors on teaching skills and two factors on tutorial attitudes. Norm related validity and reliability were confirmed in each subscale. The second survey was an attempt to make a profile and a radar-chart graph based on both self-evaluation and teachers' evaluations to provide feedback to student-teachers. Thirty student-teachers were asked to describe their ideas on the effects of these evaluation procedures in terms of improving their teaching skills. The adaptability of these sequential procedures of evaluation in formative evaluation systems was discussed.
