Interlopers and field change:: The entry of US News into the field of legal education

This article analyzes a process by which established organizational fields change through the incorporation of new field-level actors. Drawing on 137 in-depth interviews with U. S. law school administrators and faculty, the paper demonstrates how the U. S. News & World Report rankings of law schools gained a foothold in the field of legal education, how the dynamics of the field helped entrench the field position of USN and its rankings despite spirited opposition from key actors, and how these same dynamics explain how a seemingly minor change-the addition of a single actor to the roster of existing field actors transformed many aspects of this field. A close examination of this new model of field change enhances field theory by underscoring how field characteristics, such as the interconnections among actors and the web of mutual influence that these imply, themselves can facilitate change. Substantively, this research provides insight into the way that those who measure, credential, or certify key field actors and activities can achieve pervasive influence over the fields they evaluate.
