Diversity among institutions or, at least, institutional types is a policy
objective that most systems of higher education pursue. At the same time th
ose systems are also concerned about equity of access and the quality of ed
ucational opportunity. Individual institutions, for a variety of reasons ra
nging from accountability to the allocation of scarce resources, attempt to
compare or "benchmark" themselves against other institutions. Both activit
ies involve measurement, classification, and the selection of peers. Althou
gh customarily addressed apart from one another, diversity and peer selecti
on can be conceptually closely linked within single scales of similarity an
d dis-similarity. Existing paradigms that explain diversity might be too si
mple for reliable peer selection and comparison, and might fail to account
for all expressions of diversity. A case study is used to discover the conn
ections between diversity and peer selection, test existing paradigms, and
develop a modified methodology that can be used for selecting peers and mea
suring diversity.
