Not every young person is lucky enough to enjoy the support of a functional family or social network and many depend on the state in some capacity to help develop the skills necessary for achieving professional success and personal stability. A youth "ages out" of foster care when he or she reaches the age of majority (18) without having been adopted, reunified with his or her family, placed in guardianship, or otherwise given a permanent family. Aging out, in many cases, marks the end of a youth's eligibility for educational, mental health, and other services provided while under a child welfare agency's care. These youths are expected to have the skills to navigate the adult world independently upon leaving foster care.
