The Collegiate Learning Assessment (CLA) is a nationally normed test designed to measure critical thinking, analytic reasoning, problem solving, and written communication skills of undergraduate students. GVSU is part of a longitudinal study sponsored by the Lumina Foundation to study the use of the CLA to assess development of these skills during college. As a longitudinal participant, GVSU has agreed to test a sample of students at 3 stages of their college careers: as entering freshmen; as rising juniors; and as seniors. The participant cohort consists of students who entered GVSU in the fall semester of 2005. Soo far they have undergone their initial testing and their "rising junior" testing (in winter 2007). In addition, a sample of fall 2007 senior was tested to provide a cross-sectional comparison.
