Yuck.
The parents are, by and large, incredibly rude and snotty. The kids appear too serious and self-impressed. The two teachers I've met, including a 4th grade teacher who is involved in the interview process, were sour and self-important and lectured me on how many diplomats and attorneys send their children to Aiden, and how slim was the chance of a non-sibling, non-connected kid's being accepted.
Note my failure to use the word "pleasant" when describing parents, children, or teachers at this place.
Needless to say, I sent my kid to a school where laughing is not outlawed and the parents greet one-another (and strangers, gasp!) with a smile. And, gee, I am an attorney (who cares?), and, gee, there are some diplomat kids there too (who cares?).
There seems to be little of the Montessouri spirit at Aiden, even if it goes through the motions.
Send your child to a place where he/she can learn to string beads and count shells while smiling and cooperating.
Who needs more selfish, lifeless drones?
