The problem here is going to be in how this student is classified. If the student is considered to be in a grad program, the PLUS in this case could only be certified for $1500 ... grad annual max is $20,500 (of which up to 8500 can be sub, although this student's loan would be all unsub due to EFC). If the PLUS is denied based on credit report, the student could get a cosigner, get on a payment plan, or borrow some other way.
If the student is put into a post bachelor certification status by the school, this student is in a bad way. Only undergrad loans are available, and the amount is determined by the type of program the student. The max the student will get in student loans would then be (at most - the amount is determined by the program the student is in - the aid office has to review a plan of work from the student to do this) $12,500 - often just for a period of one calendar year. After this time, the student's eligibility for student loans is gone for that particular program. NO grad PLUS for a post bach status student.
It is really important for this student to know what program & what type of financial aid is available for the particular program. Check with the school.
OOPS ... I forgot to mention that student can get a TEACH grant ($4000/year) without demonstrated need --- BUT there are strings attached after graduation: https://teach-ats.ed.gov/ats/images/gen/factsheet.pdf
. She could possibly get that plus the annual loan limits up to COA.
