Trade School Loan question

Hello, My GF is attending vocational school and her total costs with financial aid (FAFSA and full pell grant) is $15000 for the entirety. She has $8000 (would go up in time with a part time job she has) in savings right now. Should she apply for a $15000 loan while having the readily available money to pay off use her $8000 to finish the first half of school and then loan out the rest. Also, which loans are best suited for her? Thanks for the help!
