The article examines how well 77 academic departments at a public university in Iran are performing. They used a method called data envelopment analysis (DEA) to measure efficiency. By looking at factors like staff numbers, salaries, students taught, and research performance, they found that about half of the departments are efficient. Different DEA models gave different efficiency scores, showing that the type of model used matters. They also found that some departments are not using their resources effectively, and there is a lot of variation between departments. Overall, the study did not find significant differences in efficiency between different fields of study at the university.
