This study aims to explore various accountability issues in the secondary school teacher preparation program. Traditionally the definition of accountability in education was focused on the activities or criteria to be pursued through an educational system and the process of accounting, reporting, or explaining those activities and criteria. This study emphasized a recursive feature in the definition of accountability, which means that continuity of the three phases- imposing responsibility on the person who is supposed to do a task, leaving to the discretion of the person, and reporting what she/he has done. After one cycle of the three accountability phases, the persons should realize what they did, learn from trials and errors, and then refine the next goals to be accomplished. Applying the concept of accountability to the secondary school teacher preparation program, three implications should be considered as follows: First, secondary school teacher preparation program should heavily focus on developing reflective and critical teacher candidates devoting themselves to various group of students. Second, integrated curriculum of teacher preparation program should be lined to the experts in pedagogy and subject area, and the supervisors at the teacher practicum. Third, the criteria of evaluating secondary school teacher preparation program should be shared with members of teacher preparation institutions and reexamined whether the performance criteria of evaluating those institutions connote the indicators of accountability of teacher preparation program. In conclusion, enhancement of autonomy of teacher preparation program, especially in the phase of process of teacher preparation program, and sharing the result of the evaluation and blueprints for the best practice in the teacher preparation were proposed.
