I would tell her to speak with her case worker before she does this. This may show she has residual function capacity which has to do with age, education and work experience which fits into SS guidelines. They find any reason they can to cut your benefits so be careful. Sometimes trying to better yourself backfires. Let me add that the SS agency as far as I remember, can take money from her benefits if she isn't able to pay her school loan, of course this won't happen until 6 months after she completes school.
