I hear it is extremely challenging to get kids in ASD, so you may want to check on whether or not there is space. Now, if your husband works for one of their main donors, like Exxon Mobile, there shouldn't be much of a problem. But, there seems to be a long waiting list if you aren't, even if your child has excellent grades.
It's not uncommon for people to get here and not find space even though they counted on it. Just make sure you ask hard questions...
Oh yeah, it is one of the most sought after school in Doha. I'm told it is very good. Too many kids in Doha to fit though. The schools are not able to expand quickly enough, so some good students end up in sub-standard schools temporarily.
