Exploring Differences in the Distribution of Teacher Qualifications Across Mexico and South Korea: Evidence from the Teaching and Learning International Survey

Abstract

Background/Context Although substantial evidence from the United States indicates that more qualified teachers are disproportionately concentrated among academically and economically advantaged children, little cross-national research has examined the distribution of teacher qualifications across schools and students. As a result, we know little about how different institutional contexts, policies, and priorities influence children's access to qualified teachers. Research Question Our research questions are: (1) Are the qualifications of lower-secondary teachers within and across Mexico and South Korea distributed uniformly across schools? (2) If not, does the distribution of teacher qualifications in each country favor less or more advantaged children? (3) How can dissimilarities in teacher-related policies and educational priorities help to explain differences in the distribution of teacher qualifications across Mexico and South Korea? Research Design We employ secondary analysis of data from the Teaching and Learning International Survey, which was conducted by the Organization for Economic Cooperation and Development in 2007/2008. We use these data to describe the distribution of various teacher qualifications across communities of different sizes and across schools with varying levels of parental education. We also explore cross-national differences in institutional priorities and teacher-related policies. We compare Mexico and South Korea because while these two countries are similar in the level of teacher hiring and assignment, they are quite different in terms of their general commitment to educational equity. Findings/Results We find that the distribution of qualified teachers in South Korea is skewed toward disadvantaged children, while Mexican teachers tend to be distributed in a way that favors more advantaged students. Specifically, in South Korea students living in rural areas and those in schools with lower average parental education have greater access to better educated and more experienced teachers. The opposite occurs in Mexico. Conclusions/Recommendations We argue that these differences are due to both explicit policies and a greater commitment to educational equity in South Korea, relative to Mexico. Moreover, these differences are likely to be related to large cross-national differences in educational performance and equity.
