This paper examines the current state of the gender gap in literacy rates and school education among Adivasi populations in India. Despite significant progress in overall literacy rates in recent decades, Adivasi communities, particularly Adivasi girls, continue to lag behind. We analyze the latest data from the Census of India, National Family Health Surveys, and other government reports to quantify the extent of the gender gap in literacy and school enrollment, attendance, and dropout rates among major Adivasi groups across different states. Root causes including poverty, lack of access to schools, cultural norms, early marriage, and lack of female teachers are explored. The paper also reviews recent government initiatives and welfare schemes aimed at promoting education of Adivasi girls and reducing gender disparity. Based on the analysis, targeted policy recommendations are made to accelerate progress in closing the gender gap and ensuring basic school education for all Adivasi girls in India.
