This paper examines the impact of two education incentive policies including tuition fee reduction and education subsidy on secondary-school enrollment of children in Vietnam. Using Vietnam Household Living Standard Surveys during the 2006–2018 period, we find that both policies significantly increase the school enrollment rate of children. The effect of these policies varies across different groups of children with a greater effect on those from ethnic minority groups, rural areas, poor and low-income households. Our findings suggest that these education incentive programs are an effective way to encourage children to enroll school, especially in low- and middle-income countries.
