Essentially, it is asking for the Student or Borrower Identification, or the Student Loan Certification, etc.
It is an easy form to understand.
After all, it is designed for students, and they don't want these things to be a problem for themselves!
It is a surprise for some, the ease in filling it out ,even if you have been partying all night, and have to submit it to concerned parties the very first in the morning.
If you take a look at it you can decide for your self if it is the simplest W9 form of all.
