This is what IRS Publication 17 has to say about student loan interest deductions:

Student loan interest is interest you paid during the year on a qualified student loan. It includes both required and voluntary interest payments.

This is a loan you took out solely to pay qualified education expenses (defined later) that were:

-For you, your spouse, or a person who was your dependent (defined in chapter 3) when you took out the loan,

-Paid or incurred within a reasonable period of time before or after you took out the loan, and

-For education provided during an academic period for an eligible student.

Eligible student. This is a student who was enrolled at least half-time in a program leading to a degree, certificate, or other recognized educational credential.

Enrolled at least half-time. A student was enrolled at least half-time if the student was taking at least half the normal full-time work load for his or her course of study.

Eligible educational institution. An eligible educational institution is any college, university, vocational school, or other postsecondary educational institution eligible to participate in a student aid program administered by the Department of Education. It includes virtually all accredited public, nonprofit, and proprietary (privately owned profit-making) postsecondary institutions.

The educational institution should be able to tell you if it is an eligible educational institution.
