You will need to check with the school administration to see if they are a eligible education institution. Not all are. Per the IRS, the definition of a full time student is defined by the school you are attending.
An eligible educational institution is a school offering higher education beyond high school. It is any college, university, vocational school, or other post secondary educational institution eligible to participate in a student aid program run by the U.S. Department of Education.

 This includes most accredited public, nonprofit and privately-owned–for-profit postsecondary institutions.

 If you aren’t sure if your school is an eligible educational institution:

• Ask your school if it is an eligible educational institution, or
• See if your school is on the U.S. Federal Student Aid Code List at https://ifap.ed.gov/ifap/fedSchoolCodeList.jsp
