"Honors Colleges in the 21st Century" contains the work of 56 authors representing 45 different institutions, which makes this the largest and most comprehensive group of honors leaders ever to appear in print together discussing honors colleges. Particularly notable is the fact that eleven of the chapters are co-authored by individuals from different institutions. A wide range of institutional perspectives are represented: public and private, large and small, R1 flagships and regional, two- and four-year, religious and secular, and HBCU. The professional positionality of writers is similarly diverse, including faculty, staff, and administrators. Because the diversity of settings in which honors education takes place is one of its great strengths, this volume is not meant to provide a single prescriptive account of how honors colleges should be set up or run. This volume is also framed through the data collected in a 2021 survey, the most wide-ranging survey of honors colleges ever conducted, though it is important to note that the data were drawn from 166 honors colleges during the 2020--2021 academic year, which was severely disrupted by the COVID global pandemic.
