Depending of what type of school you are looking for. I don't know what your nationality is, so if you are looking for an Indian school I cannot help but good English schools are the American school and Doha Collage (UK system) which are both neer Al Waab area. DESS is also a good English school. However I don't think you will be able to find space in any of these schools for next year which is starting in September 2008.
There are a lot of nice compounds in Al Waab area, very nice area to stay in.
