From ICS kindergarten to ESF primary school

Dear all

Is there a lot or only a few cases that ICS kindergarten students can be granted a chance to be interviewed at ESF primary school?

Will ICS kindergarten students have preference over other non-ESF international kindergarten or less preference?

As there is only three ESF kindergarten, they are too far from the place I live. I am struggling whether I should let my student to travel for more than one hour just for a kindergarten.

Please advise.
