Some approved undergraduate degree programs (majors) are sub-divided into specific fields or specialties. Specializations occur within a major, while minors and designated emphases occur outside the major. A specialization is an undergraduate program of study which enables a student to focus on courses in a particular field within a degree program. The specialization pursued appears on the student's transcript but usually not on the diploma. Establishment of specializations requires review by the Berkeley Division and approval of the Chancellor's Office. Major codes are established for each specialization by UC's Office of the President. In Berkeley's Student Information System, each undergraduate specialization has its own academic plan code.
