Yes you would be a minority but the 80% black may not be an accurate assessment, culturally speaking. My daughter goes to Robert Goddard Montessori and if this is any indicator a large portion of the blacks are not "African American" but Africans and other "black" peoples from many parts of the world. Its quite diverse in that way. These tend to be highly educated families. My experience has been quite good. The parents are conscientious and very nice. Their kids are smart, polite and well-behaved. Incidentally, my daughter's 2 best friends at school happen to be white (I'm black as in African American). I love the parents at this school. They are very involved and supportive. We get invited to many a birthday party and there are always many cultures and races represented. So to answer your question....its a non-issue. I don't know about the French Immersion school but I assume the same thing applies since lots of Africans are French speaking (my wife is from Cote D'Ivoire and speaks French). Fitting in isn't a problem with children. They just see another kid. sadly, its us adults who seem to have issues playing well with others. The French Immersion is the best school in the county. Good luck. I hope your child gets in! I'm trying to get my daughter in there as well.
