Drawing on first-third wave data from Seoul Education Longitudinal Study(SELS), this study
analyzes the effects of Education Welfare Priority Project on cognitive achievements of
elementary school students. This study focuses on the objects which start education welfare
priority in 2011 in order to appropriately manage the characteristic of corresponding schools and
students before the welfare project in 2010. For minimizing the selection bias strictly, a
propensity score matching method(PSM) was used by respectively choosing 513 students from
supported and unsupported school to analyse effects of Education Welfare Priority after
primarily applying ordinary least square regression modeling method(OLS). The results show
that the effects of Education Welfare Priority Project on the cognitive achievements of students
differ by subjects. In specific, Education Welfare Priority Project has a positive impact on
English achievement by controlling for student and school characteristics. Educational welfare
school students have high level of English achievement than students in the school with no
welfare. As a matter of fact, it is suggested that the Education Welfare Priority is partly
positive to students' cognitive achievements.
