 PRTF stands for Psychiatric Residence Treatment Facility. 20 years ago, it's a federal and public program. About 20 years ago, they began to realize that a lot of kids were coming out of long-term psychokinesic. They've been there for two or three years and just were not making it a community. So they came up with a PRTF program, which is a step down from psychoschool. Now when the MCOs began to get involved about seven years ago, we also found out that we could work with kids who have blown through every local community program or in danger of moving to long-term psychokinesic. So if those kids come back, girls have the kids who are in danger of having to do that. And that's why the PRTF program was created.
