The way Princeton’s NPC explains how to handle divorced parents is pretty clear and makes it less likely that applicants will make the mistake of assuming that only the custodial parent matters in a divorced parent situation.
Seems like other colleges that use both divorced parents’ information ought to look at this example.
(Note: Princeton may differ from other colleges in its policy if the custodial parent is remarried.)
