& Zebari, 2021). In fact, teachers’ effectiveness can not be assessed in any criteria. In
language teaching, teachers have different styles of teaching and they also can be
classified as native teachers and non-native teachers, unlike teachers of other subjects.
The field of language teaching is subject to rapid changes and language teachers need to
maintain the interest, creativity and enthusiasm in their profession (Whitehead &
Greenier, 2019).
School system effectiveness refers to the extent to which every unit within school
carry out their routine functions that can promote or hinder the attainment of set
objectives (Owan, 2019). School system effectiveness implies a state where activities
within every school are tailored towards students’ development, school growth, and goal
attainment. Insight has been provided as to what constitutes an effective school
(Vongkulluksn, Matewos, Sinatra, & Marsh, 2018). It follows, therefore, that the
judgment of any school depends on five major aspects-the teachers, students, principals
or school leaders, the physical facilities, and the school environment. It is one thing to
understand what constitutes an effective school, as it is yet another thing to measure the
effectiveness of a school (Ilomäki & Lakkala, 2018).
An effective teacher has a high rate punctuality, good time management, good
academic performance of students, good relationship with other staff, respect for rules
and authority, adherence to school norms, effective communication, proper record
keeping, and good professional behavior. The performance shown by the teacher is an
indicator of the effectiveness of the achievement and the success of learning objectives
(Donohoo, 2018). Teacher’s performance is an indication of the success of the teacher in
carrying out institutional tasks and other specific tasks demanded by the nature of the
teacher’s position. Efforts to improve teacher performance can be done by increasing
work productivity, work quality, work efficiency, job satisfaction, work discipline, work
excellent, and work development.
The reputation of the school and its impact on the quality of the educational
institutions depends on the quality of the teachers working in it (Hassan, Mirza, &
Hussain, 2020). Therefore, for school development it requires teachers with high
discipline. Teacher’s performance is, basically, the teacher’s achievement in his work.
Teacher’s performance can be also assessed through the extent to which the learning
carried out, which can give significant effect to students. Specifically, the work target
requires the teacher to formulate learning objectives in the form of behavior that is
transferred to students. This means that learning quality is the main determinant factor of
the success of the learning process (Jackson, Fleming, & Rowe, 2019).
Due to the importance of the role of the teacher’s performance in the quality of the
education and the quality of human resources, it is natural that the reality of the low
human development index and the low quality of the education in Indonesia is a result of
the low teacher’s performance (Jin, Qian, Chin, & Zhang, 2020). Work discipline is an
influential factor of teacher’s performance. Work discipline is a behavior to comply with
all organizational rules in doing work to achieve expected goals (Bakti & Hartono, 2022).
Teacher’s discipline is very important in carrying out the duties and obligations as
instructors, educators and advisers. High discipline will be able to build professional
performance, because with a good understanding of discipline, the teacher will able to
observe the rules and strategic steps in implementing learning.
Teacher work discipline which includes attendance at school, adherence to
teacher’s work standards, commitment to duties, responsibility for duties, and courtesy
and neatness have gone well. Good discipline reflects the amount of responsibility a
person has towards the tasks assigned to him. Communication and work discipline are
predictors of employee performance. Good discipline reflects the amount of one’s
