The highest rates of child marriage among girls in South Asia were seen in Bangladesh and Nepal. Both Nepal and Bangladesh have a direct connection between secondary school completion and child marriage when it comes to educational achievement according to a UNICEF report in 2019. The report indicates that efforts to prevent child marriage have advanced more rapidly over the past ten years, particularly in South Asia, but they are still moving far more slowly than is necessary to achieve the Sustainable Development Goal (SDG) of ending child marriage by 2030. Many research on education and child marriage repeatedly demonstrates that having more education is generally linked to later marriage and childbirth across a variety of circumstances. A report by Human Rights Watch shows that in Bangladesh, women with primary, secondary, and higher education were, respectively, 24 percent, 72 percent, and 94 percent less likely to marry at a young age than women with no formal education supports the association between lack of or poor education and child marriage.

A study found that programs and policies for education should prioritize keeping girls in school until the ages of 13 or 14, when they may be switching from primary to secondary schooling and are most at danger of child marriage.

In Bangladesh, parents worry that keeping their girls in school would make it harder for them to find suitable spouses and that education and marriage were seen as a trade-off for their daughters. Several underlying issues, such as poverty, gender norms, and others, have an effect on this process.

Preventing child marriage requires co-ordination of multiple stakeholders along with government in taking various initiatives and scaling up existing education system to prevent the dropouts. Creation of readily available digital marriage records across the country as evidence of marriage. At the primary and secondary levels, free education must be guaranteed. All students must get a uniform education, and the required measures should be made to identify the problems and implement the right corrective measures.
