|(a) The Board shall have the authority to modify or revise a Board-approved field of study curriculum when a need for such a revision is identified, as specified in current Board policy and procedures. (b) The need for a revision or modification to a Board-approved field of study curriculum may be identified by one the following methods, or by other methods that are similarly appropriate: (1) notice of a change in licensure, certification, or accreditation standards that would affect the field of study curriculum and lower-division requirements for a field of study or academic discipline; (2) notice of a change in curricular structure or content that is part of a pervasive change in the academic discipline served by the field of study curriculum, as documented by national or regional professional organizations, faculty organizations, or other indicators of best practices in the discipline; (3) receipt of a request from at least three public institutions of higher education that are affected by the field of study curriculum under consideration for modification, including at least one two-year and one four-year academic-degree-granting institution. The request and justifications for the request should be made by the chief academic officers of the institutions, in a joint memorandum sent to the Commissioner. (c) Any proposed modification or revision to a Board-approved field of study curriculum should be evaluated by an advisory committee convened under the conditions cited in §4.30(a) of this title (relating to Criteria for Evaluation of Core Curricula). Recommendations for modifications or revisions to a Board-approved field of study curriculum should reflect the advice and wisdom of an advisory committee made up primarily of teaching faculty from the academic discipline(s) affected by the field of study curriculum under consideration.
