An English grammar school would likely be better for teaching and on a par or worse for facilities and resources.

Generally speaking, true private schools in Doha are not comparable to the better English public and private schools. Even DESS and Doha College, which follow the National Curriculum of England and Wales, compare themselves primarily to state schools in England (albeit very favorably). The American school, which is amongst the most expensive and best resourced, is comparable to one the high-end state schools in a prosperous American suburb.
