American or French school (Casablanca)

Hi everyone, we are moving to casablanca in summer Protected content would like your views on American versus French school system. I have heard the French schools in morocco are good, is this true? how does the level of education in American schools compare? Our 6 yr old is bilingual so language is not an issue. If American we would like either Calafornia American school or George Washington. Have not visited the American school in oasis and have heard they are moving to bouskara golf city which would be great location wise but know nothing about the school. If anyone has kids in these schools or has any information which could be useful we would greatly appreciate your help. Many thanks in advance and hope to see you in casa, Monica
