Statistical, Empirical Data to Support Smaller Writing Class Sizes and Retention

I'm serving on a summer committee which has been tasked to research if and how smaller freshmen writing class sizes serve to incease retention within both the freshman writing course(s) and later composition courses. The report that we'll be presenting in September is directed at the college deans and provosts, so we need to uncover data that supports what most writing teachers know--smaller classes equals a better chance at student success, and we need to consider the issue from an institutional / financial as well as classroom/pedagogical perspective.
