36 / THE GRADUATE SCHOOL
 MINOR.-With the approval of his supervisory committee, the student may
choose one or more minor fields. Minor work may be completed in any de-
partment, other than the major department, approved for master's or doctor's
degree programs, as listed in this Catalog.
 If one minor is chosen, the representative of the minor department on the
supervisory committee shall suggest from 18 to 36 credits as preparation
for a qualifying examination. Of course, a part of this background may have
been acquired in the master's program. If two minors are chosen, each must
include at least 12 credits. Competence in the minor area may be demon-
strated through a written examination conducted by the minor department
or through the oral qualifying examination.
 Course work in the minor at the doctoral level need not be restricted to
the courses of one department, provided that the minor has a clearly
stated objective and that the combination of courses representing the minor
shall be approved by the Graduate School before registration beyond 6 credits
of course work applicable to the minor. This procedure is not required for a
departmental minor.

 SUPERVISORY COMMITTEE

 Supervisory committees are nominated by the department chairman, ap-
proved by the dean of the college concerned, and appointed by the Dean of
the Graduate School. The committee should be appointed as soon as possible
after the student has begun doctoral work, and in general no later than the
end of his third quarter of equivalent full-time study. The Dean of the
Graduate School is an ex officio member of all supervisory committees and
should be notified in writing well in advance of all examinations conducted
by such committees.
 DUTIES AND RESPONSIBILITIES.-The duties of the supervisory committee
 are as follows:
 1. To inform the student of all regulations governing the degree sought.
 It should be noted, however, that this does not absolve the student from
 the responsibility of informing himself concerning these regulations.
 (See Student Responsibility.)
 2. To meet immediately after appointment to pass on the qualifications
 of the student and to discuss and approve a program of study for him.
 3. To meet to discuss and approve the proposed dissertation project and
 the plans for carrying it out.
 4. To conduct the qualifying examination or, in those cases where the
 examination is administered by the department, to take part in it. In
 either event, no fewer than five faculty members shall be present for the
 oral portion of the examination.
 5. To meet when the work on the dissertation is at least one-half com-
 pleted to review procedure, progress, and expected results, and to make
 suggestions for completion.
