42 C.F.R. § 57.3202
(c) In the case of a school which is requested to provide the Secretary with cost increase justification under paragraph (b) of this section, the Secretary will be responsible for increases in tuition and other educational costs charged to students participating in the scholarship programs over the amount charged for the school year immediately preceding the increase only to the extent that they are: (1) Attributable to uncontrollable costs, such as fuel costs, mandated cost-of-living increases in wages, salaries and fringe benefits, (2) attributable to costs of maintaining and improving the quality of the health professions education provided by the institution, such as hiring additional faculty to improve the faculty-student ratio, costs incurred in off-site training of students, and necessary improvements in teaching equipment. Increases in patient care and research costs are allowable as part of an increase in tuition and other educational costs only to the extent that they can be documented as clearly necessary to maintain and improve the quality of the education being supported; or (3) attributable to loss of revenue from other sources which was used solely for the maintenance and improvement of the educational system.
These three categories of valid escalators of tuition and other educational costs are exclusive. However, the examples within each category are merely illustrative and not meant to be inclusive.
