Purpose: This study empirically examines the impact of motivation, transformational leadership and involvement in strategic planning (SP) on academic staff performance at higher education institutions (HEIs). It also examines how academics' involvement in SP mediates the associations between motivation, transformational leadership and performance. Design/methodology/approach: This article conducted a quantitative approach based on a self-administered survey. Partial least squares structural equation modeling (PLS-SEM) was applied to analyze the data gathered from 192 faculty members at governmental HEIs in Oman. Findings: The results indicated that academic staff motivation has a significant and positive impact on their involvement in SP and performance in HEIs. It is also revealed that employee involvement in SP activities is significantly affected by transformational leadership, while the latter does not affect academic staff performance. There is also a significant association between academic staff involvement in SP and their performance. Moreover, the relationships between motivation, transformational leadership and performance are fully mediated by academic staff involvement in SP at HEIs. Originality/value: The current empirical work is one of the few endeavors to develop an integrated structural model to investigate how faculty members' performance could be affected by motivation, transformational leadership and involvement in SP. Furthermore, it is considered one of the first attempts to explore the intervening role of academic staff involvement in the SP process in the connections between motivation, transformational leadership and performance within the HEI realm.
