So once you join you are housed in a dorm on campus. Once you start to leave they will help you find a job, a home and give you starting money. You will not leave the campus until all of this is done. Once you are out on your own, You can rejoin Job Corps if you are still under aged and do a different program and get all the same benefits

I don't know if they have explicit partnerships, but it's certainly a program that case workers in the foster care system are aware of. My foster daughter's case worker explored it with her as one of a range of options after high school. (She ended up just getting a regular job instead.)

I'd be really curious to know how it works out for former foster youth who try it. On the one hand I can imagine the structure and support to be really valuable to kids who have been in the foster care system. On the other hand foster youth often benefit most from systems that can give them lots of second chances and can work with them to meet their individual needs, and I don't know if that's something Job Corps can offer.
