While the difference with this study, the researchers did not conduct research on the leadership of school principals. In addition, the data analysis method used is different, namely in previous studies using the classical assumption test, and multiple regression testing, while this study used SEM (Structural Equation Model) data analysis techniques.


Introduction
The quality of education does not only talk about the results, but also the process of education itself. Education is said to be of high quality if the teaching and learning process runs well and smoothly. Likewise with the results obtained are satisfactory. The quality of education when viewed from the results, refers to the learning achievement obtained by students and schools for a certain period of time. In addition, the school's ability to produce the best graduates also shows the quality of education in the school. Because these graduates will contribute to advancing Indonesia. According to Winkel (Darmadi, 2017) states that learning achievement is evidence of the success that has been achieved by someone. So learning achievement is the maximum result achieved by someone after carrying out learning efforts. The average value of the National Examination can describe student learning achievement, the following is the data on the average value of the National High School Examination in Makassar City from 2015-2020.

Table 1. The Average Value of the High School National Examination in Makassar City in 2015-2020
Source: https://puspendik.kemdikbud.go.id/hasil-un/ Based on data, the average UN high school scores in Makassar City from 2019 to 2020 experienced a significant decline, both public high schools and private high schools. Given the importance of the teacher's role in the learning process, every teacher is required to have academic qualifications and competence as learning agents. Rusman (2012) asserts that the competencies that teachers must have (eg) pedagogic competencies, namely the ability to manage learning, personality competencies, namely personal abilities that are steady, stable, mature, wise and authoritative to be role models. for students, professional competence, namely the ability to master learning materials broadly and deeply, and social competence, namely the ability of teachers as part of the community to communicate and socialize effectively. The achievement of these four competencies can be seen from the performance shown by each teacher. Talking about teacher professionalism, of course, cannot be separated from the teacher's own professional development activities. To anticipate the challenges of the increasingly severe world of education, teacher professionalism must be developed. (Sudrajat, Ahmad 2014) Broadly speaking, teacher professional development activities can be divided into three types, (ie) intensive, cooperative development, and independent development. Ideally every teacher can involve themselves in the three types of teacher professional development activities. If a teacher does not try to be involved (involved) in these three types of professional development activities, it is almost certain that he will fall professionally. The government's efforts in this case the Ministry of National Education and Culture (Kemdikbud) have actually tried to continue to develop the teaching profession, including increasing the qualifications and requirements for higher education levels for teaching staff, teacher certification programs, and the formation of PKG. (Teacher Activity Center), MGMP (Teacher Activity Center). Subject Teacher Conference), and KKG (Teacher Working Group). So theoretically, with the government's efforts to develop the teaching profession, it should be able to improve teacher performance, especially improving the quality of education, but in reality there are still some basic problems that need to be resolved, for example the low quality of teachers in various types and levels of education.
This research is the development of variables from previous studies with different subjects, objects, and research indicators.

Discussion The Effect of Teacher Professional Development on Teacher Performance
Independent development provides broad autonomy to teachers. The teacher tries to plan activities, carry out activities, and analyze feedback for self-development. The technique used can be through self-evaluation (self-evaluation/self-supervision). The teacher can carry out several activities for self-development in addition to the activities that have been determined, there are several alternative activities, namely: (Mulyana, 2010) making writings/scientific works (KTI) in the field of education, finding appropriate technology, making teaching aids, participating in curriculum development activities. The findings of this study are in line with the results of research conducted by Devi Esisna, et al. (2017) found that the teacher development program carried out or not carried out did not have a significant effect on the performance of the Gugus V Kindergarten teachers, Harau District, Lima Puluh Kota Regency. In contrast to research conducted by Udiyono (2011) found that there is a positive and significant relationship between teacher professional development work and teacher performance in a case study at Widya Dharma University, Klaten. Both studies have something in common, they both focus on performance. While the difference is the object and subject of the research. One looks at the performance of Kindergarten teachers, while the other looks at the performance of Lecturers.

Influence of Competence on Teacher Performance
Competence possessed by a teacher has an influence on the success of teacher performance in carrying out their duties as teachers and educators. The competence possessed by a teacher explains that the professionalism of a teacher is not only shown when the teacher is in the learning process or during the teaching and learning process, but the professionalism of the teacher is shown more than that, in the sense of being able and always carrying out his teacher duties in accordance with his field. Prihadi (2004) suggests that competence produces effective performance, this means that competence has a close relationship with performance. It can be said that if the teacher has competence in his field, the teacher will improve effective performance. The findings of this study are in line with the results of research conducted by Udiyono (2011) found that there is a positive and significant relationship between professional competence and teacher performance (Case Study at Widya Dharma University Klaten). Research conducted by Jannah Anita, et al (2012) found that teacher competence had a significant effect on teacher performance at SMP Negeri 7 Bandung. Research conducted by Fitriana Nina and Sopian (2013) results of the study indicate that competence has an effect on teacher performance at SMA Negeri 16 Palembang. However, several studies differ from this study. Among other things, what was done by Raharjo Sri (2014) found that competence had no effect on the performance of elementary school teachers in Surakarta City, Central Java. Research conducted by Untara Sutrisno Budi (2014) found that teacher competence had no effect on teacher performance in elementary school teachers at the UPT Education Office, Gunem District, Rembang Regency.

The Effect of Educational Facilities and Infrastructure on Teacher Performance
Only one school had a science laboratory and library room which was badly damaged. Management such as needs analysis, procurement, inventory, and optimal maintenance are needed so that later the facilities and infrastructure owned can contribute according to the purpose of holding them and are always in a condition ready for use. With good and optimal management of facilities and infrastructure, every educational process in schools will run according to what is expected because it is supported by the availability of complete and appropriate facilities according to needs, so that it will have an impact on the quality of every educational process in schools. The findings of this study are in line with the results of research conducted by Jannah Anita, et al. (2012) found that infrastructure facilities have a significant effect on teacher performance at SMP Negeri 7 Bandung. Research conducted by Djatmiko Eko (2006) found that facilities and infrastructure had an effect on the performance of Semarang State Junior High School teachers.

The influence of educational facilities and infrastructure on student learning achievement
The availability of learning facilities as a means of supporting the ongoing learning activities is very influential on learning motivation and student achievement, because the availability of learning facilities affects the smooth running of the student learning process. This is in accordance with the opinion of Dalyono (2001), which states that the completeness of learning facilities will help students in learning, the lack of learning aids or facilities will hinder their learning progress. The findings of this study are in line with the results of research conducted by finding that Wina Dwi Puspitasari (2016) found that the effect of learning facilities on student achievement in social studies subjects in the VSDNTarikolot class, Majalengka Regency, was acceptable and has been proven true. Research conducted by Nanik Legiwati (2016) found that there was a significant effect of the use of learning facilities and infrastructure on the learning outcomes of social studies subjects for class VII students of SMPN 3 Grati Satap Pasuruan City.
