Knowing how things have gone for her, and the situation with her toddler brother, I'd be considering a small amount of slack. To live here she'd:
Need to pull down a B or better in her remaining class, and enroll for the next semester the day it opened.
Be cooking and scrubbing (hand her the flylady lists)
Volenteer when school isn't in session
Come up with a plan, not a grand one, but some sort of plan for the next 2 years.
Since her mother wasn't much in the raising department, she may take longer to get going on life, and it may not occur to her that things need cleaning (my cousin is much the same, unless there's mold she doesn't "see" dirt, she's used to it).
All of the "teen" jobs are gone here too, when Winco built a new store over 10,000 applications for less than a hundred jobs.
