REQUIREMENTS FOR THE PH.D. / 37
 6. To meet when the dissertation is completed to conduct the final oral
 examination and to satisfy itself that the dissertation is a piece of original
 research and a contribution to knowledge. No fewer than five faculty
 members shall be present for this examination, but only the members
 of the official supervisory committee are required to sign the dissertation.
 MEMBERSHIP.-The supervisory committee for a candidate for the doc-
 toral degree shall consist of no fewer than three members selected from the
 graduate faculty. At least two members will usually be from the college or
 department recommending the degree, and at least one member will be drawn
 from a different educational discipline. The chairman and at least one addi-
 tional member of the committee will be members of the resident Doctoral
 Research Faculty of the University of Florida.
 If a minor is chosen, the supervisory committee will include at least one
 person from outside the discipline of the major for the purpose of represent-
 ing the student's minor. In the event that the student elects more than one
 minor, each minor area may, at the discretion of the departments concerned,
 be represented on the supervisory committee.
 When a minor is not designated, the supervisory committee will include at
 least one person from outside the discipline of the major who has been
 appointed to the graduate faculty. The Graduate Council desires each super-
 visory committee to function as a university committee, as contrasted with a
 departmental committee, in order to bring university-wide standards to bear
 upon the various doctoral degrees.
 In unusual cases the doctoral research may require the guidance of a spe-
cialist from an area of study other than that of the chairman of the super-
visory committee. In such cases the department chairman may recommend ap-
pointment of a chairman and a co-chairman, with the latter being a mem-
ber of the graduate faculty, but not necessarily of the Doctoral Research
Faculty. A co-chairman may also be appointed for the purpose of serving
during a planned absence of the chairman; in this case both the chairman
and the co-chairman shall have been appointed to the Doctoral Research
Faculty.

 LANGUAGE REQUIREMENT
 A Ph.D. student is required to demonstrate proficiency in a language other
than his native tongue. This language will normally be French, German,
Russian, or Spanish, the choice to be made by the supervisory committee.
A student may not, however, use a language in which he is majoring to
satisfy the language requirement. Proficiency in the language is to be demon-
strated in one of the following ways:
 1. By satisfactory performance on the nationally administered Graduate
 School Foreign Language Test of the Educational Testing Service,
 which the student is encouraged to take before entering Graduate School
 or as soon as possible thereafter.
