Master Teacher System(MTS) has been adopted in order to foster a teaching-centered
culture in that master teachers help novice teachers as well as any teachers who want to
improve their teaching practice. Since the MTS started implementing at the school level in
2011, there has been a number of issues surrounding the MTS such as unclear roles and
status of master teachers, conflicts between master teachers and other teachers(e.g., deputy
principals), teachers’ trust for master teachers’ professionalism. Although many studies have
reported these issues, the dearth of study examined how these issues support or inhibit the
MTS from fostering a teaching-centered culture, which is an initial policy purpose of the
MTS. Through the survey of 4,274 teachers from schools currently implementing the MTS,
the results of this study imply that teachers’ trust for master teachers’ professional abilities
and clear roles and status of master teachers help school teachers perceive that teaching the
MTS fosters teaching-centered culture at the school level.
