Applications for need-based financial aid programs are screened mainly on the basis of the income of the person who supports the family financially. There is no financial aid program in which acceptance is decided exclusively on the basis of the fact of a single parent household. Be sure to check screening criteria in application guidelines for respective financial aid programs as the criteria differ from one financial aid program to another.
