Nothing in this part shall be interpreted as limiting the authority of the financial aid administrator, on the basis of adequate documentation, to make adjustments on a case-by-case basis to the cost of attendance or the values of the data items required to calculate the expected student or parent contribution (or both) to allow for treatment of an individual eligible applicant with special circumstances. However, this authority shall not be construed to permit aid administrators to deviate from the contributions expected in the absence of special circumstances. Special circumstances may include tuition expenses at an elementary or secondary school, medical, dental, or nursing home expenses not covered by insurance, unusually high child care or dependent care costs, recent unemployment of a family member or an independent student, a student or family member who is a dislocated worker (as defined in section
2801 of title
29), the number of parents enrolled at least half-time in a degree, certificate, or other program leading to a recognized educational credential at an institution with a program participation agreement under section
1094 of this title, a change in housing status that results in an individual being homeless (as defined in section
11302 of title
42), or other changes in a family’s income, a family’s assets, or a student’s status. Special circumstances shall be conditions that differentiate an individual student from a class of students rather than conditions that exist across a class of students. Adequate documentation for such adjustments shall substantiate such special circumstances of individual students. In addition, nothing in this subchapter and part
C of subchapter
I of chapter
34 of title
42 shall be interpreted as limiting the authority of the student financial aid administrator in such cases
