Now is a key moment in the history of American Lasallian universities. This document, Prologue and Paradigm, attempts to seize this moment by offering a view of the Catholic, Lasallian university in terms that are comprehensive, specific, and flexible. Lasallian universities face considerable challenges and none greater than how to successfully compete with other universities, many of which possess much greater resources, while not only retaining but enhancing their Lasallian identities. Indeed, we believe that enhancing our Lasallian identities will make us more competitive because students and parents will find attractive an approach to education based on Lasallian values. Lasallian assessment is a response to these developments and a paradigm for integrating Lasallian values with those of the liberal arts and the university. Its goal is to create a truly integrated Lasallian university.
