As a minority I will have to agree that Friends is not a diverse environment.
I was never impressed with the "Quaker" aspect of the school and the claims about multicultural and racial diversity. I would always recommend ways to improve the school's diversity but found the administration didn't really want suggestions. I think they assumed they were doing a great job.
We had a difficult time at Friends School securing financial aid as well. We were told that since we were not AA they would not provide aid for my family. This forced me to seek out other private school options that were.
At least at the current school my children attend they are honest in that they don't think it is diverse enough and want input on how to change that. I feel this is a much better attitude then just assuming your have diverse school.
If you really want diversity, send your kids to public school! Of course in Baltimore we all know that's not an option!
