This paper presents the results of a model that simulates the effects of varying preferential admissions policies on the academic profile of a set of 35 small liberal arts colleges. An underlying assumption is that all schools in the set use the same ratio of preferential to non-preferential admissions. The model predicts that even drastic changes in this ratio have little effect on these institutions' comparative academic profile, as measured by the mean SAT score of the incoming class. When preferential admissions rates are altered, admissions numbers must be altered as well to achieve a desired class size; the model predicts that these changes effectively cancel each other out.
