The Independent Curriculum, which strongly emphasizes student autonomy and holistic development, marks a paradigm shift in education. The efficiency of Social Sciences Learning assessment techniques is essential in this framework. This study aims to integrate the findings from qualitative and quantitative analyses to provide a more complete picture of effective assessment strategies in the Independent curriculum. In terms of methods, this study uses a mixed-methods approach that combines quantitative and qualitative techniques and in-depth analysis in MAXQDA software. To obtain the data, teachers were interviewed from their perspective about their experience of conducting evaluation procedures in Social Sciences Learning. This information was collected through observations from four teachers in four different elementary schools. This synthetic approach provides a comprehensive understanding of the complex dynamics that affect the assessment of Social Sciences Learning in the Independent curriculum. Rigid data management and analysis is made easier with MAXQDA, enabling effective investigation of new themes and patterns. The results identify areas for improvement and provide insight into how assessment strategies and curriculum goals fit together. Finally, this research guides pedagogical practices and promotes sustainable development within Indonesia's education system.
