Ity all depends on your the fees you can afford. I suggest you go through fiew schools before you commit.

I visited Al Salam British School, which is in Ghusais. The owner is a British convert, and she has been here for over 25 years. Check their site.

The school in Fees are average, and it seemed to me that it's what I am looking for. Registration start in April, so I am provisionnally booking my 5 years old who will (start on Grade 1) and (3.5 years who will start on KG1) there.
Although your daughter will be 6, it will depend on her previous attendance (KG, Reception or school) corresponding to(KG1, KG2, Year 1) in Britain.
But the bset to tell is the school administrator.
Good luck.
