INTRODUCTION
Teachers become the main and leading role in the teaching and learning process, building effective interactions with students and their learning environment in order to produce a quality learning process according to professional duties so as to produce superior, productive and competitive human resources. To achieve this, of course, need to be supported by the performance of teachers as educational professionals. Performance according to Mathis & Jackson (2012), "is the result of work achieved by individuals in carrying out the tasks assigned to them that have a strong relationship with institutional goals, customer satisfaction, and contribute to the economy". The teacher performance according to Wibowo (2016), 'is the ability shown by the teacher in carrying out his duties or work'.Maximum teacher performance is an expectation for the community, government and schools, but the reality so far in the field shows that there are still many teacher performances that have not met expectations. Based on the results of preliminary observations in several West Jakarta Senior High Schools, it shows that the performance of high school teachers is still not optimal. There are still many teachers who are not yet professional in making learning tools and only imitate learning tools from the internet or from the previous year, less innovative learning, conventional learning methods, and less competent in applying learning methods by utilizing technology according to current needs with an online system because During the covid-19 pandemic, most teachers only give assignments to students without going through the process and learning cycle that should occur. There are still many teachers who do not make students the subject of learning, which is not in line with the view of Student Centered Learning.

Existing leadership will influence the group in achieving goals. The way a person leads can bring the group or organization towards the success or failure of achieving the goals that have been set. Leadership style has a lot to do with the success of a leader in influencing the behavior of his followers. Leadership is an art, namely the art of influencing others to take actions and actions that the leader wants in accordance with organizational goals. As an art, leadership cannot be generalized, each person has their own way, their own style to influence others in the leadership process. It usually happens even though the background of the leader is the same, but because the ways and styles are different, the appearance of the leadership will be different (Sulistiyani, 2007).
The principal as a functional teacher who is given the task to lead a school where the teaching and learning process is held, or a place where there is interaction between teachers who give lessons and students as recipients of lessons. (Wahyusumidjo, 2008). Thus, the principal is actually the pinnacle of decisionmaking and the leader for school members in carrying out educational activities and the learning process.

According to Mulyasa (2013) the principal must have: (a) personality, (b) knowledge, (c) understanding of the vision and mission, (d) ability to make decisions, and (e) ability to communicate. Based on some of these opinions, that Principal leadership is the principal's ability to influence and coordinate school members to achieve the goals that have been set.Teacher performance is also evidenced by the commitment of teachers to the school which is a very important behavioral dimension for school progress. According to Wibowo (2016), organizational commitment is in the form of a person's willingness to bind himself and be able to provide evidence of loyalty to his organization because he feels he is involved in the activities of the organization. Then reinforced by Sutrisno (2010) that the individual (who has organizational commitment) will show a strong desire to become a member in a group, a high business will for the organization, and a belief in the values and goals of the organization.

By having these four competencies, teachers are expected to be able to carry out their duties as professional educators.
