Objective: To explore the international legal framework regulating the right to education and assess its effectiveness in addressing the root causes of social inequality in educational access. Methods: This study employs a qualitative analysis of universal and subject-specific international norms on the right to education. It includes a review of international treaties and subject-oriented norms that cater to specific groups such as children, women, and persons with disabilities. The research methodology also incorporates expert surveys to identify and analyze the main determinants of social inequality affecting educational access. Results: The study highlights that while international legal norms establish a robust framework for the right to education, significant gaps remain in addressing socio-economic, racial, gender, and disability-related disparities in education. Key determinants of inequality include socio-economic status, racial and ethnic identity, gender, and disability. Conclusion: Despite comprehensive international regulations aimed at ensuring the right to education, persistent social inequalities necessitate enhanced international legal mechanisms and stronger enforcement of existing norms to ensure equitable educational opportunities for all. © 2024, Centro Universitario Curitiba - UNICURITIBA.
