The primary objective of this current study is to conduct a comprehensive analysis of the ways in which various leadership styles influence the overall organisational effectiveness of higher education institutions. Furthermore, the goal of the research is to determine whether demographic variables have an impact on the evaluation of organisational efficacy and the perceptions of leadership of individuals within these institutions. Data were meticulously collected from a sample of 215 teachers in Himachal Pradesh, India, who held a variety of positions at both private and public higher educational institutions. This was done in order to attain these objectives. The results of this study provide compelling insights: Initially, it is clear that demographic variables, at least to a certain extent, influence perceptions of organisational efficacy and leadership within higher education institutions. These variables include, but are not limited to, age, gender, educational background, and years of experience. Secondly, the research emphasizes a substantial correlation between the organisational efficacy of these institutions and the transactional style of leadership. In the context of higher education in Himachal Pradesh, transactional leadership is a significant influence on organisational efficacy, as it is defined by a focus on structured rewards and explicit communication of expectations. These results enhance comprehension of the manner in which demographic factors and leadership dynamics interact to influence the operational efficiency of educational institutions in this region.
