Education is a very important aspect of a person's life. In Bangladesh, several different types of institutions are available for youth's education, including private schools, public schools, and religious schools called madrasahs. For these institutions to continue to run properly, teachers, students, and a curriculum must be present. A major aspect of the education system in Bangladesh is Islam and religious learning. The main objective of this study is to identify the effect of the teacher-student relationship in public schools, private schools, and madrasahs in Bangladesh. The research methods, including document review, observation and survey, were used to collect information from the target respondents in public, private, and madrasah schools in Bangladesh. The results show that teachers have a different kind of relationship with their students, depending on the school in which they are teaching. This is strongly determined by the number of students in the school, the degree of accessibility to each school, and social perceptions of the teacher-student relationship. The main purpose of this study is to understand how teacher-student relationships impact student's grades since these relationships have a great effect on the learning environment in all three types of institutions. Positive relationships help students feel loved and acknowledged, consoled and secure. This research, concentrated on three schools to perceive how educators' relationships with students have impacted their school life and how it has affected their studies.
