Cooper, Fusarelli, and Randall(2004)'s four dimension policy lenses-normative, structural, constituent, and technical- are used to enable new admission officer system in a range of complexity. The findings of this study were as follows; First, comprehensive review in the selection process should be focused on the consideration of underserved group of students in class, region, and type of high school. Second, new admission officer system should be understood in the context of battle filed between central government and university. Universities should implement this system collaborating with high school teachers to encourage admission officers to be proactive in the consideration of applicants' high school curriculum activities and to reduce the effects of private college admission consulting company. Third, financial supports of the central government for admission officer system should take into account college characteristics, private vs. public, central vs local, small vs. large institutions. The supports should extend to high school teachers, and educational research institution in order to spread the information about new admission officer system toward students and their parents. Fourth, professional development of newly hired admission officer should be enhanced by each college's educational program. In conclusion, admission officer system should set up an accountability system by informing the plan of college admission and selected students profile and monitoring the college admission decision process.
