In order to be a Caretaker of the Old, a person needs to be calm, patient, and interested in helping the elderly and assisting with release.

In Lois Lowry's The Giver, Fiona is assigned this position as she is a responsible person; she is also sensitive, kind, friendly, and gentle. When, for instance, Jonas volunteers at the House of the Old in Chapter 4, he sees Fiona there. She helps an old man from the tub and gently pats his body with a towel; then she helps him put on his robe. However, there are some things about which she is unaware, such as release, so she just believes that she cares for the elderly. 

Later, when Jonas has been assigned to be the Receiver and goes for instruction by the Giver, he learns about release, and he asks about the Old: "Do they kill the Old, too?" The Giver says, "Yes, it's true." Shocked, Jonas asks about Fiona, who loves the Old and is in training to care for them. "Does she know yet?" he inquires. The Giver responds that Fiona has been trained in "the fine art of release...." He also tells Jonas that since feelings are not part of the life she has learned, she is capable of releasing people.
