Private education is the fastest-growing sector of post-secondary education in Asia and worldwide. This growth is especially notable in developing countries with a long history of state-controlled, public education. Vietnam has had a strong public, post-secondary education sector that has only recently begun to experience growth in non-public institutions. In this research, I investigate how the growth of the private sector may influence stratification in Vietnam. I find that private and other types of non-public institutions are more likely to serve more advantaged students from South Vietnam. They pay higher costs to acquire their post-secondary credentials; however, these students also seem to choose more lucrative fields like science, technology and engineering, and business, perhaps as a way to ensure good returns to this investment. This research suggests that as the private sector in Vietnam expands, the influence of family background and region of residence on post-secondary attendance may grow. [ABSTRACT FROM AUTHOR]
