Teacher support significantly affects student learning and directly relates to their academic development. Learning satisfaction is the subjective perception and evaluation of learning quality on the part of the student, which represents, to certain extent, the quality of education. Based on data from a questionnaire survey of 1251 migrant children in grades three throughout six, this study analyzed how teacher support impacted the learning satisfaction of migrant children. Research findings indicated that teacher support had a significantly positive effect on migrant children's learning satisfaction; and that teacher support indirectly and positively affects their learning satisfaction through the separate mediating effect of their learning engagement as well as via the chain mediating effects of their academic adjustment and learning engagement.
