This study aims to analyze and compare the senior secondary education systems in Indonesia and Vietnam with a focus on educational equity covering four main aspects: Access to Education, Teaching Quality, Curriculum Relevance and Education Efficiency. This study is motivated by various challenges faced by Indonesia, such as inequality in access to education between urban and rural areas, low quality of teaching, inconsistency of the curriculum with the needs of the 21st century, and lack of innovation in learning. Vietnam was chosen as the object of comparison because of its success in improving the quality of education evenly despite having limited resources. This study uses a qualitative approach through a literature study of education policies and practices in both countries. The results of the analysis show that Vietnam implements various effective strategies, such as providing incentives for teachers in remote areas, community-based teacher training, strengthening competency-based curriculum, utilizing digital technology, and consistency in the direction of education policy. These findings provide an overview that Indonesia can learn from these policies to strengthen educational equity, improve teaching quality, adjust the curriculum to current needs, and encourage sustainable educational innovation.
