Plans of action prepared by States parties to the Covenant in accordance with article 14 are especially important as the work of the Committee has shown that the lack of educational opportunities for children often reinforces their subjection to various other human rights violations. For instance these children, who may live in abject poverty and not lead healthy lives, are particularly vulnerable to forced labour and other forms of exploitation. Moreover, there is a direct correlation between, for example, primary school enrolment levels for girls and major reductions in child marriages.
