A 362 performance evaluation across several periods indicate the need for more strategic and measurable human resource management interventions (Hoy, 2. Theoretically, transformational leadership is understood as a leadership style that inspires, motivates, and develops followers through clear vision, intellectual stimulation, individual consideration, and idealized influence (Bass, 2014. Avolio, 2013. Northouse, 2. Work motivation is viewed as internal and external drives that move individuals to achieve organizational goals with high enthusiasm and commitment (Deci, 2017. Gagny, 2. Several empirical studies show that transformational leadership and work motivation are positively correlated with performance across various sectors, including education (Judge. Podsakoff, 2. Research in the Indonesian context shows similar findings, as found by Angelya et al. in Madrasah Aliyah. Elghawi et al. in private high schools in Semarang, and Nurjannah & Windasari . in junior high schools in Sidoarjo. However, specific studies on high school teachers with a simultaneous focus on both variables are still relatively limited. This research aims to assess the extent to which transformational leadership and work motivation influence teacher performance at SMA Mahawarman Bandung Regency. The method used is a quantitative survey with a saturated sample . = . and regression-based path analysis, supplemented by t-tests. F-tests, and coefficient of determination. In summary, the results show significant positive effects both simultaneously and partially. the conclusion is that transformational leadership and work motivation are key factors in improving teacher The content of this research is in the realm of human resource management (HRM) in the secondary education sector, highlighting two strategic instrumentsAitransformational leadership and work motivationAias drivers of teacher performance. The expected impact includes improving learning quality, increasing student academic achievement, and strengthening school reputation. At the strategic level, the results of this study can serve as a reference for developing school principal leadership capacity and formulating effective, transparent, and sustainable motivation systems (Meyer, 2.

Literature Review Transformational Leadership Transformational leadership is a leadership style that inspires, motivates, and develops followers through clear vision, intellectual stimulation, individual consideration, and idealized influence (Bass, 2014. Avolio, 2013. Yukl, 2. This theory was developed by Bass and Avolio, emphasizing the leader's ability to transform and inspire followers to achieve higher goals (Northouse, 2. Dimensions of Transformational Leadership according to Bass . and Avolio . Idealized Influence - the leader becomes a role model respected and trusted by followers Intellectual Stimulation - the leader encourages followers to think creatively and Individualized Consideration - the leader provides personal attention to the needs and development of each follower Inspirational Motivation - the leader communicates a clear vision and motivates followers to achieve it. Research in the Indonesian education context shows that transformational leadership of school principals significantly influences teacher performance (Angelya et al. , 2024. Ghassani et al. , 2024. Mulder, 2024. Zulpikar et al. , 2. Podsakoff . found that transformational leadership behaviors increase follower trust, job satisfaction, and organizational citizenship behavior. Work Motivation Work motivation is the internal and external drive that moves individuals to achieve organizational goals with high enthusiasm and commitment (Deci, 2017. Gagny, 2. The Self-Determination Theory (SDT) developed by Deci and Ryan explains that work motivation is influenced by basic psychological needs: autonomy, competence, and relatedness (Deci, 2. In addition, the Job Demands-Resources (JD-R) Theory by Bakker . explains that work motivation is influenced by the balance between job demands and available resources. Dimensions of Work Motivation according to Deci . and Locke . Intrinsic Motivation - internal drive to perform work due to personal satisfaction Extrinsic Motivation - external drive such as rewards, recognition, or appreciation Need for Achievement - desire to achieve standards of excellence and overcome Organizational Commitment - emotional attachment and loyalty to the organization (Meyer, 2.

Simultaneous testing proves the third hypothesis (H. with the finding of a significant positive influence of transformational leadership and work motivation on teacher performance (F = 18. p < 0. RA = 0. The contribution of both variables of 5% indicates that the combination of effective transformational leadership and high work motivation plays an important role in improving teacher performance, although there is still 62. 5% variation explained by other factors such as pedagogical competence, facilities and infrastructure, and student characteristics (Hackman, 2015. Tett, 2. This finding is in line with research by Judge . which shows that transformational leadership has higher predictive validity compared to transactional leadership in predicting performance. Research in Indonesia also shows a significant simultaneous influence between transformational leadership and work motivation on teacher performance (Angelya et al. , 2024. Elghawi et al. , 2024. Widyaningshih et al. , 2. Northouse . explains that transformational leadership can increase followers' intrinsic motivation through empowerment and capacity development, which ultimately improves performance. Kahn . found that positive psychological conditions . ncluding high motivatio. contribute to better engagement and performance. The implication of these findings is the need for SMA Mahawarman to develop programs to improve the transformational leadership of school principals and comprehensive teacher motivation systems to optimize learning performance. This can be realized through the development of an inspirational school vision, providing intellectual stimulation, attention to individual teacher needs, as well as structured reward and career development systems. Based on Job Demands-Resources theory (Bakker, 2. , schools need to ensure a balance between work demands and available resources to increase teacher motivation and Meyer . emphasizes the importance of building organizational commitment through attention to teachers' basic psychological needs. Yukl . suggests that transformational leadership development can be done through continuous training and Research in Indonesia shows that effective implementation of transformational leadership can improve education quality (Prastyowati et al. , 2024.
