Hi Nicole:
There are numerous reasons for pretesting, and you've described on very good way to use it. We can aslo assess where student are performaing at the very beginning of a new class, gather information to understand trends, provide a prelude of "coming attractions", and maybe most importantly, understand where we might have to tweak our curriculum to better meet the needs of one particular cohort of students vs. previous or future students takiung the same calss.
