The sentinels program is largely as Tim described. There are no preconditions. They have to abide by the terms of the lease. They sign a lease, not with us but with the building owner. We have already created a link of confidence with that person such that the caseworker has a rapport with them. That's where we have our leverage to help them.
Our objective is not to create perfect human beings; it's to take people who are in a state of homelessness and give them an opportunity to sustain themselves outside of homelessness, in their imperfections and challenges. We try to reduce the potential for them to fall back on the street as much as possible.
