This study to assess the role of non-state actors in protecting children's right to education within the framework of human security, focusing on post-disaster learning recovery in Aceh, Indonesia. The Aceh floods at the end of 2025 caused damage to infrastructure in a number of areas, including rural Aceh, which is difficult to reach. This condition significantly worsened the education infrastructure, threatening long-term human development. Through a qualitative approach with a descriptive case study design, this study analyzes how NGOs and the private sector collaborate to fill the governance gap left by formal state mechanisms. This study uses a human security perspective in which education is treated not only as a pedagogical obligation but also as a key component of protection against human vulnerability. The study aims to assess the development of non-state actors' efforts within formal and non-formal collaborative governance frameworks to build educational resilience in disaster-prone rural areas. The results of the study show that non-state actor diplomacy facilitates the rapid mobilization of emergency learning and psychosocial support, which is often delayed in top-down bureaucratic responses. This study demonstrates the contribution of non-state actors in promoting non-traditional security by repositioning educational sustainability as a fundamental element of human recovery after the disaster in rural Aceh, Indonesia.
