This study examines the correlation between general mental ability and academic performance among elementary school students in North Tripura, using a sample of 200 learners (92 male and 108 female) chosen through stratified random sampling. Data were collected using a general mental ability test by Dr. R.P. Srivastava & Dr. Kiran Saxena and the students' academic scores from their most recent examinations. Descriptive and inferential statistical methods, including t-tests and correlation coefficient(r), were employed to interpret the data. The outcomes reveal a notable positive connection in the middle of general mental ability and academic performance. Furthermore, no significant dissimilarities in general mental ability and academic performance irrespective of gender. However, the results highlight significant disparities between urban and rural students, with urban students outperforming their rural counterparts in both general mental ability and academic performance. The study’s outcomes have practical implications for educators, parents, and policymakers. They underscore the importance of addressing cognitive and contextual disparities through targeted interventions to improve educational outcomes. The findings also advocate for integrating innovative pedagogical strategies and psychological principles to foster cognitive and academic development among students. This research contributes to the broader understanding of the interplay between cognitive abilities and academic success, providing a foundation for future studies aimed at enhancing education systems in diverse socio-economic and geographical contexts.
