The purpose of this study is to investigate the problems of multi-layered system in the curriculum
decision making and curriculum standards documents development; and to suggest improvement ways
necessary for realization of the school-centered curriculum in terms of the curriculum decision. As a result,
the form and content of the MPOE (Metropolitan and Provincial Offices of Education) Curriculum
Arrangement and Implementation Guidelines, developed by the Educational Office of each region, were
composed the same as or similar to the content of the national curriculum standards document; so, they
emasculated the national curriculum standards, and it was hard to identify any distinctions among the
MPOE Guidelines by several regions. Moreover, in the diversified structure, schools are oversupplied by
demands and rules to follow, and they rather have a difficulty in displaying autonomy. Therefore, this
study suggested that the MPOE do not make the middle-level curriculum but abolish this, and dualize the
curriculum composed of two systems instead: the national curriculum standards outside of school that
reflects globally and nationally universal validity; and the school curriculum standards inside of school that
reflects regional characteristics of schools and cities and provinces. The MPOE should play a role of
‘supporting’ schools, so that they could plan and operate fine and excellent educational activities.
