Sustainable management practices in education have become increasingly important as education systems face growing financial pressures, regulatory demands, and expectations to contribute to sustainable development. This study examines sustainable management practices in education through an integrated economic and legal perspective, using secondary data from internationally recognized sources. A comparative, descriptive research design is employed to analyze economic indicators related to education financing and access alongside legal and governance variables, including constitutional recognition of the right to education, sustainability-oriented policies, and governance decentralization. The findings reveal that education systems characterized by higher levels of public investment, supportive legal frameworks, and decentralized governance structures demonstrate stronger sustainability performance, particularly in terms of access and progress toward Sustainable Development Goal 4. The results further indicate that economic efficiency and legal accountability are mutually reinforcing, with effective governance mechanisms playing a critical role in translating legal commitments into sustainable institutional practices. By integrating economic and legal dimensions, this study contributes to interdisciplinary scholarship on sustainability in education and provides policy-relevant insights for strengthening governance and management frameworks. The findings underscore the need for coherent strategies that align financial sustainability with enforceable legal obligations to support long-term educational resilience and equitable development
