Child #1 has sibling preference but ranked school ABC at #3, and didn't get into their #1-2.
Child #2 has no preferences but ranked school ABC at #1.

Who gets the seat at school ABC?

What if child #2's lottery number is higher than child #1's?[/quote]

Child #1. Sibling preference trumps no preference every time.[/quote]

I second this.  100% according to the logic of stable match.  School ABC prefers Child #2 over #1 so this creates an equitable match for all parties involved.[/quote]

We were arguing this point yesterday, but as of yesterday, who is disputing this part of it?

The part we are now disputing is this:
Same scenario as above EXCEPT Child #2 DOES have sibling preference.  Who gets the spot then if both children have sibling preference but Child #1 ranked the school #3 and didn't get into 1-2, vs. Child #2 who ranked the school #1?

If you believe parent ranking has no effect beyond what order the computer tries to place you, you believe basically that at this point it's random.  Those of us saying parent ranking matters are saying that in THIS scenario, Child #2 will get the spot.  Hands down.  And random computer assigned lottery number does not impact anything at this point.[/quote]

If there is a tie, then there is a tiebreaker and it is not based on parent rank.  It's based on your randomly assigned lottery number according to the method documents found earlier in this thread.[/quote]
