My 3 children are at Doha Montessori & British School and they are really enjoying it.  The school recently moved to brand new purpose-built premises which I can tell you are fantastic.  I know from recent experience that getting school places out here is a nightmare, particularly if you have more than one child to place.  Unfortunately there is a lot of snobbery going on as to which school your child goes to, which is totally rediculous - two of the "top" british schools are crammed into the smallest buildings and are very overcrowded.  Also some are like little British enclaves with pictures of the Queen on the wall (we dont even have those in the UK).  Having travelled half way around the world with the kids to live in Doha I wanted them to have the experience of going to school with children from all over the world, not just those that held British passports.
