Cultural behavior is important in creating a favorable environment for teaching and learning activities. The current study examines teachers' and students' assessment of cultural behavior education among high school students. There were 394 participants who completed the survey—55 teachers (14%) and 339 students (86%). Teachers' assessment of the manifestation of cultural behavior had mean scores from 1.53 to 4.05; all the mean scores of the methods and forms of cultural behavior were above three. This study examines all the mean scores of the teachers' assessments of the requirements of cultural behavior that are greater than four. In addition, all mean scores of teachers' assessment of the efficiency of cultural behavior outcomes were above three. Teachers must actively study, cultivate, and improve their professionalism and carry out the responsibility of educating students regarding cultural behavior. Creating a culture of respect, kindness, and responsibility in the classroom and establishing guidelines for teachers, staff, and students are some suggestions proposed for high schools to form cultural behavior among students. Teachers and staff must exhibit model behavior and be approachable and friendly to students. Initiatives both inside and outside the school should be organized to influence student conduct. Positive interactions between the family and school are necessary, thus teachers must maintain contact with families all year round, not only when issues develop.
