Open-source software (OSS) has become a valuable resource for corporate, educational, and social processes, reducing digital divides in emerging countries. This paper proposes an open-source software acceptance model (OSS-AM) to examine determinants of OSS adoption among students in emerging economies. A quantitative methodology with a descriptive correlational approach was employed, collecting data from a representative sample of 504 students. Confirmatory factor analysis showed strong associations between attitude towards use and variables such as compatibility, quality, flexibility, and security. This study reveals that skill development through practical education, perceived usefulness, training, and compatibility are the most influential factors in students' adoption of OSS.
