In this article, we demonstrate the use of generalizability theory in analy
zing existing faculty evaluation data. Three measurement conceptualizations
representing different purposes of faculty evaluation were conceived to ac
count for the existing data structure. Variance components associated with
these conceptualizations were estimated from random samples taken from an e
xisting faculty evaluation conducted in a university in the western United
States. Within each of the 3 conceptualizations, 3 decision study considera
tions are presented together with the generalizability coefficient estimate
s. Practical implications for faculty evaluations are discussed.
