It was far too easy for my daughter to get student loans. I remember having to go to the bank and actually reading through and signing the documents. Now it is online and is just one click. I can't remember any sort of instruction that went on prior to taking the loan.
My family are sophisticated consumers of student loans. My older daughter did not take any, and I only had my daughter take two loans of the four semesters she attended nursing school. She only took subsidized loans (she is a nurse and I thought some of her compensation on her first job might be loan forgiveness).
Instruction of college expenses, career prospects, ROI on the degree, and student loan terms actually need to be first presented in 9th grade (when decisions can be made that will make an impact). A follow up should occur the summer before the senior year or at the start of the senior year.
