This research is concerned with educational attainment of junior school students who have originated from two culturally less-privileged groups: migrant workers and land-lost farmers. Guided by Bourdieu's habitus theory, several impact factors indicate different academic achievements between the two targeted groups with qualitative approaches. Parental expectation is the major difference, since children gain motivations from their parents. Several personal attributes such as independence and concentration contribute greatly to academic achievements.Parental occupation and skills can greatly affect the way of education for both groups.
