This study was an attempt to investigate the existence of classroom management problems in public high schools in the UAE and to find out the effective techniques and required skills needed for teachers to manage their classes successfully. I used a mixed method approach composed of qualitative and quantitative data collection and analysis. The findings indicate that there is a serious problem regarding classroom management in public high schools in the UAE. Moreover, the study suggests some beneficial implications for teachers for effective classroom management. One of these implications is the teachers'' need to build rapport between them and students as a means for a closer relationship that facilitates classroom management. In addition, teachers should know something about students'' social backgrounds in the UAE as this is a first step to dealing effectively with students and then for effective classroom management. Moreover, the findings indicate that most students like the affective treatment from their teachers.
