This study investigates the academic achievement of 10th-grade girl students in government schools in Karbi Anglong, Assam, focusing on home and school environments. Data were collected from 300 female students across four schools using a Home Environment Scale and a School Environment Scale. Findings revealed a strong positive correlation (0.706) between home environment and academic success, indicating that better home conditions enhance performance. School environment factors also significantly contributed to academic achievement. Regression analysis showed that home and school environments explained about 67% of the variance in academic performance (R value of 0.818).Recommendations to improve academic outcomes include enhancing learning environments, strengthening parent-child relationships, improving school conditions, increasing parental involvement, and promoting curricular activities. These initiatives can significantly benefit female students in the region.
