The Institutional
Engagement Index is a method developed by NSSE to evaluate
how a particular college or university is doing on each of
the five benchmarks, compared to how one would expect that
college or university to perform, given its size and other
objective characteristics. This
index consists of three measures: the actual score on the
five benchmark indices; a predicted score, based on an ordinary
least squares (OLS) regression model using data from the Integrated
Postsecondary Education Data System (IPEDS); and a residual,
the result of subtracting the predicted score from the actual
score. The
resulting residual, either positive or negative, might be
considered a measure of "educational effectiveness."
The following
IPEDS variables, if available, were used in the regression
equation used to calculate the predicted score: whether the
institution was public or private, admissions selectivity
(from Barron's 1999), undergraduate enrollment, urbanicity,
percentage full-time and part-time, sex, racial/ethnic composition,
educational and general expenses per student from 1995-96
IPEDS, endowment or assets (land, buildings, and equipment)
per student from 1995-96 IPEDS, student-reported major field,
student-reported age, percentage of students who completed
the survey via the web. For
