42 CFR § 57.308 - Nursing student loan promissory note.
(a) Promissory note form. Each nursing student loan must be evidenced by a properly executed promissory note in a form approved by the Secretary. The school must safeguard the promissory note against fire, theft, and tampering.
(1) Each promissory note must state that the loan will bear interest on the unpaid balance computed only for periods during which repayment of the loan is required, at the rate of 5 percent per year.
(3) A copy of each executed note must be supplied by the school to the student borrower.
(b) Security. A school must require security or endorsement if the borrower is a minor and if, under the applicable State law, the note signed by him or her would not create a binding obligation. The school may not require security or endorsement in any other circumstances.
