Susan Poser, president of Hofstra University (NY), writes:  In early 2022, after six months as the new president of Hofstra University, I and my senior leadership team embarked on an exercise to choose peer institutions. This was done in the context of a multifaceted, yearlong initiative to gather input from students, faculty, staff, alumni, and trustees to kick off strategic planning. How do we define our university, we asked stakeholders, and what are our ambitions? Coincidentally, as we were completing this peer exercise last month, The Chronicle published a visualization showing nearly 1,500 colleges’ self-identified peer institutions.  The visualization shows not only which institutions a college identified as its peers, but also which institutions chose that college as a peer. The visualization is fascinating and reveals a lot about how institutions think about their peers and themselves.
