First off, somewhere you must affirm the money is to be used for educational expenses
, although that includes up to a certain amount of living expenses based on your location (determined by your school).
The answer to your question is maybe. I'll try and explain the best I can.
Let's say tuition is $25,000
Your school determines that the total cost of education (tuition plus books, fees, living expenses, etc) is $45,000
Your scholarship will take care of the $25,000, leaving $20,000 remaining.
Your stipend is considered earnings, NOT scholarship. This is important because when it's used as earnings, it's used to calculate student contribution on the FAFSA. If it is mischaracterized as scholarship, it will also be sutracted of the top, eg. if stipend is $14,000, now you'd only have a max borrowing of $6,000.
All this assumes no other scholarships or income.
I had the same issue last year and bugged the financial aid guy until he showed me the instruction used to determine how to classify the stipend.
Basically, if the money varies from person to person, like it might if it were need-based, it'd be considered scholarship, but because we all receive the same amount and because it's reported on the FAFSA from a W2 statement (in other words, it's wages being used already to determine student contribution) so it should not be deducted as more scholarship money.
Hope this helps
