This paper aims to explore the utility of the Economic, Social, and Cultural Status Indicator (ESCS) as a dynamic and informative measure for promoting educational equity. Beginning with an examination of its components (HISEI, PARED, and HOMEPOS), emphasis is placed on how the ESCS can contribute to identifying initial inequalities, assessing the impact of educational policies, ensuring equitable resource allocation, designing personalized interventions, promoting equal opportunities, and informing policymakers. Despite its advantages, the article critically addresses challenges such as cultural sensitivity, the comprehensiveness of data collection, and ethical considerations.
