Higher education is playing a pivotal role to ensure the sustainable development of Bangladesh. Students’ academic performance is one of the main indicators of the quality of the academic institutions. It may depend on various personnel involved in academic, administrative and also their working environment. This study aims to identify the determinants of educational performance of the students of Bangladesh Agricultural University (BAU). For measuring students’ academic performance, the stationarity test of the transition probability matrix of the grades of students in successive semesters was used. Step-wise multiple regression analysis was used to identify the determinants of students’ academic performance. The results reveal that the variation in student’s performance occurred over time (semester to semester). Students’ academic results were significantly associated with students’ study hours, and satisfaction about their results, degree and study environment. This study recommends for better student counseling system, improvement of curricula and teaching methods and proper maintenance of study environment.
