Abstract

This study conducted to examine the role of social capital in the academic performance of students at Badakhshan University. Using Cochran's formula, a sample of 355 students was selected by probabilistic quota sampling from a population of 4,195 students enrolled in the nine schools of Badakhshan University during the fall semester of the academic year (2025). Two specific data collection questionaries were developed and employed. Data were analyzed in descriptive and inferential sections using SPSS. Results showed that although students' levels of social capital and academic performance was less than the desired standard. However, social capital had a strong relationship with students' academic performance and exerted a positive and significant effect. The results also indicated that among the four components of social capital, the social values component, in the first step, and the social relations and social participation indicators, respectively, in the next steps, had the greatest impact on the academic performance of students at Badakhshan University, and the social trust component did not have a significant impact on students' academic performance.
