This report provides new evidence into the factors that predict school drop out for children in Bangladesh. It also examines similarities and differences between children who enter late into primary schooling, those who are permanently excluded and those who drop out. Our results show that the relationship of the child within the household and the possible support received from parents when the child requested help for school work were factors associated with the risk of drop out. In addition, over age in the final years of primary school and low school attendance were signals of a high risk of school drop out. Children who started school late were similar to children who drop out in terms of background family characteristics. However, children who were permanently excluded from school were poorer and more marginalised than children who dropped out. Several recommendations are drawn from the analyses of this report.
