The principle of expediency is one of the fundamental concepts in Islamic jurisprudence, whose role in political, legal, and social spheres has always been of interest; however, the educational capacities of this principle, especially in relation to policies related to children's rights, have been less systematically examined. This research aims to explain the position of expediency in Islamic education and assess the possibility of utilizing it in the Iranian child rights system. The research method is descriptive-analytical and, with an interdisciplinary approach, examines the sources of Imami jurisprudence, verses and narrations, domestic and international legal documents, and the views of educational scholars. The findings of the research show that the principle of expediency in Islamic jurisprudence, with its rational and moral foundations, has a high capacity for education-oriented policymaking in the field of children. Also, applying this principle to the rule of "the best interests of the child" in the Convention on the Rights of the Child shows that it is possible to extract from Islamic teachings a native and dignity-oriented model that is in harmony with the educational needs of the day. The conclusion of the research is that Islamic jurisprudence, relying on rules such as no harm, negation of harm, guardianship, and justice, has the ability to present an educational and child-oriented system in the form of educational, legal, and cultural policies; provided that conceptual reinterpretation, dynamic ijtihad, and institutional coordination are realized at the executive level.
