This paper is based on the ideas that the current teacher evaluation and promotion systems do not contribute to principal's professional development and that we need to reform the process of hiring and recruiting school principals. To support this idea, this study examined the current teacher evaluation and promotion systems based on the current laws, regulations, and research papers and analysed the problems of these systems. As a conclusion and suggestions, three directions to reform the principal's hiring and recruiting systems are suggested: 1. Separating the certification and promotion systems of classroom teachers and that of school principals and adopting the dual systems instead. Because the role of teachers and that of principals are totally different and need to be redefined in our schools. This dual system will contribute to improve the quality of teachers and principals as well. 2. Redefining the principal's instructional leadership in the schools. Principal`s roles is more focused on as resource provider, as curriculum and instructional initiator and supporter, and as a catalyst for teaches' expanding opportunities to explore different methods of learning. 3. The areas of principals' autonomy and professional areas should be respected. The balance of control and autonomy in school teaching is based on the principals' influence area and that of teachers. The educational preparation, career path, and professional development of the principals should be redefined and specified. The main directions for reforming hiring and recruiting school principals should be set to enhance the authority and power of principals and to improve their professional development.
