For students at state-supported colleges and universities, the information must include the approximate level of support received by students in each tuition category. That information may include consideration of the following: Expenditures included in the educational cost formula; revenue forgiven from waived tuition and fees; state-funded financial aid awarded to students at public institutions; and all or a portion of appropriated amounts not reflected in the educational cost formula for institutional programs and services that may affect or enhance the educational experience of students at a particular institution. For students attending a private college, university, or proprietary school, the information shall include the amount of state-funded financial aid awarded to students attending the institution.
