Obtaining a place for your child at school is one of the biggest headcahes for any expat here, and indeed in the Gulf. All British schools have very long waiting lists. Doha College and Park House have closed their lists for 2008 . Some companies reserve a block of places at schools for future employees. For the rest one is free to chose your school.
The situation is dire. I will go so far as to say unless you have secured places for your children, do not even sign the contract.Two new schools are opening in September whch may have some openings- London International School , and another one called Debakey.Good luck.
