This thesis aims at investigating the differences and similarities in English language teaching of MONE and IB schools in Ankara. Participant MONE schools are state owned and IB schools are private institutions. This research focused on criteria such as English language teaching and learning environment at schools and students’ motivation level toward learning English. In order to assess these criteria, school observation checklists, semi-structured interviews, and questionnaire were chosen as the instruments of data collection. Independent sample t-test was conducted to measure scores of students in the survey. The findings showed that IB schools have a clear advantage over their counterparts in terms of activities and extra materials used in teaching and IB students had slightly higher motivation level towards learning English in many aspects of motivation.
