Knowledge of good English speaking schools? (Baku)

Hi everyone, I'm considering moving to Baku in the new year with my young daughter. We would be joining my husband who recently started a new job there.

I am concerned about my daughters schooling in Baku, she is still in Primary education and I am anxious not to disrupt her education, by moving her away from the outstanding school she attends here in the UK.

Through research on the internet I have found 3 schools; Baku Oxford School, British School Baku and the International School of Azerbaijan. Anyone know anything about any of these schools? How good are they in comparison to good/outstanding schools in the UK? Thanks.
