Each eligible institution shall designate an employee or group of employees who shall be available on a full-time basis to assist students or potential students in obtaining information as specified in subsection (a) of this section. The Secretary may, by regulation, waive the requirement that an employee or employees be available on a full-time basis for carrying out responsibilities required under this section whenever an institution in which the total enrollment, or the portion of the enrollment participating in programs under this subchapter and part
C of subchapter
I of chapter
34 of title
42 at that institution, is too small to necessitate such employee or employees being available on a full-time basis. No such waiver may include permission to exempt any such institution from designating a specific individual or a group of individuals to carry out the provisions of this section.
