if they are primary age, and their english is ok, then i would highly suggest DESS, it hs a lovely campus, much larger classrooms than DIS etc, and also they have much better facilitis than DIS (Doha college primarr)I can speak from experience, i mean thats where i went to primary all those years ago, my sister(whos 13years oldere than me) went to that school and i still think its one of the best schools in qatar for that age group, check their website out www.dess.org
