The diversity issue, I get. That I completely understand.

I can't see why they would pull a settled child from a french hdc to a french centre... and that would have me frustrated, too, unless they were upfront about them being on a waitlist with you?

The only thing I can think of is that some parents may think that the centre has a certain "prestige" and want their children enrolled there simply because of that.

I don't know. It was brought up once to me during an interview, that the family was looking for a temporary spot until an opening became available in the centre of their choice. I thanked them for their honesty but didn't accept them for many other reasons.
