Disclaimer: This is based on published reports available on the Dubai schools site here and the Sharjah schools site here.
The most recent available data is 2023. The list is based on schools which have either an association with COBIS (Council of British International Schools), AoBSO (Association of British Schools Overseas) and/or BSME (British Schools in the Middle East).
Each school has its own context for changes in leadership and staffing which can affect staff retention.
Advice to prospective parents and staff is to research each school in detail before considering any intent to commit to a school.
