LITERATURE REVIEW AND HYPOTHESIS DEVELOPMENT 2.1 Managerial Principal
The headmaster has a significant role and obligation in managing his school as a manager.The ability of the principal as a school leader to carry out the responsibilities and role of a manager cannot be separated from his ability to manage his school (Nurhaco 2021.According to Kasidah (2017), the principal's competencies are "Personality competence, managerial competence, entrepreneurial competence, supervision competence, and social competence.Sohiron (2015) The principal's competence is all the skills or abilities of the principal to lead and carry out his duties and responsibilities well and understand the school as a complex and unique organization.
The relevance of managerial coaching for school managers in order to achieve successful and effective educational goals in schools, the education management process plays an important role.After all, schooling is a system with many components and various activities that must be controlled effectively and systematically.Without the support of good management processes, schools can only achieve chaotic organizational speed, which will never effectively achieve educational goals.Nurhaco (2021) therefore, every educational activity in schools requires clear and realistic planning, effective and efficient organization, mobilization and incentives of all school workers to continuously improve the quality of their performance, and continuous supervision.According to Akdon (2002) stated that managerial ability is a set of technical skills in carrying out duties as a school manager to utilize all available resources to achieve school goals effectively and efficiently.

Professional Competence of Teachers
According to Hasanah (2012), competence is a complete unity that describes the potential, knowledge, skills, and attitudes assessed, which are related to certain professions with regard to parts that can be actualized and referred to in the form of actions or performance to carry out certain professions.Nurhadi (2017) explained that teacher competency standards are developed as a whole from 4 main competencies, namely: 1. Pedagogic competence; 2. Personality; 3. Social; and 4. Professional.These four competencies are integrated in teacher performance.Professional competence is the ability to master learning materials broadly and deeply that allows guiding learners to meet the competency standards set in national standards of education.Rivayanti (2020) Teacher professional development is an effort made to advance and improve the quality and efficiency of work of all different personnel in the school environment, both educational and administrative personnel.Professional competence is the teacher's basic ability in knowledge of learning and human behavior, the field of study he fosters, the right attitude about the environment and having skills in teaching techniques.The success of teachers in carrying out their profession is largely determined by the four with an emphasis on teaching ability.

METHOD
This literature review focuses on the effect of principal supervision on teacher performance.The review process begins using Google Scholar, with the keyword, "Principal's Managerial Competence in Teacher Professional Competency Development".Article criteria that can be included in this study such as referring to keywords and the range of research years between 2015 -2023.

RESULTS AND DISCUSSION
Based on the results of the literature review obtained, the analysis shows that most of the articles focus on the impact of the principal's managerial competence on the professional competence of teachers.It can be seen from the review article that most of the principal's managerial competencies have a major influence in improving the professional competence of teachers.Many factors that hinder the implementation of teacher professional competency development are: 1) Supporting facilities and infrastructure in the development of teacher professional competence; 2) Limited financing capacity; 3) Motivation from teachers who have not been maximized.Based on this, in the implementation of teacher professional competency development what is needed is a work system based on the principle of togetherness, providing space for teachers in self-development, making meetings aimed at developing teacher professional competencies.

CONCLUSION
Based on the analysis that has been done.It can be concluded that the managerial competence of the principal is an important aspect in the development of teacher professional competence.So further research or study is needed on other aspects as reference material and input for schools and principals to support the development of teacher professional abilities.

LIMITATIONS AND ADVANCED STUDY
The weakness in this study is that this study only discusses the managerial competence of school principals in one aspect, namely the professional competence of teachers.So further research or study is needed on other aspects as reference material and input for schools and principals to support the development of teacher professional abilities.
teacher is defined as having competence if he is able to teach his students well.The basic competence is a description of what a person can do at work, as well as what form the work can see.Professional teachers are teachers who have the competencies required to perform educational and teaching tasks.
