Qatar has recently faced a tremendous reform in education that requires changes in many domains and causes a lot of challenges. A very serious challenge is teachers' retention where many teachers tend to leave their schools looking for new jobs. In independent schools as well as governmental schools, teachers switch jobs and therefore schools suffer from teachers' shortage. This empirical study used interviews, surveys, and questionnaires to assess novice teachers as well as experienced teachers from both governmental and independent schools, examining the issues of teacher retention. The paper explored the important factors that, as perceived by teachers, drive them to leave their profession. Research has shown that an enormous number of teachers are leaving their jobs and\or moving to other jobs. This problem has risen to an alarming level that has to be considered and investigated. In this study, we tried to collect as much data as possible to identify the main reasons behind the problem of teacher retention. This investigation will assist school leaders in defining what causes teachers to leave their job and may be help them in identifying strategies to help retain teachers and encourage them to become valuable contributors in the school. A school culture that involves teachers as part of the school leadership team is the kind of culture that promotes higher student achievement. Maintaining teachers who are capable in their positions builds sustainability in a school. Such sustainability will most likely, as research has shown, lead to a safer more secure student environment which helps raise student achievement. This research was conducted to focus on the teacher retention problem in primary schools for girls in both independent and ministry schools in Qatar. Findings might differ from those for secondary and preparatory schools as well as for boys schools. Three appendices are included: (1) Teacher Retention Problem in Girls Primary Schools; (2) Teacher Retention Problem in Girls Primary Schools; and (3) Teacher Retention Problem in Girls Primary Schools.
