This study investigates how first year Principles of Economics courses assessment items predict achievement in post principles economics courses. Of particular interest is how achievement in different assessment forms (assignments, multiple choice questions, and constructed response questions) predicts future performance. I use assessment data compiled from principles and post principles economics classes at the University of Canterbury from 2002-2008. I also control for performance in first year mathematics, statistics, accountancy and management. I find that constructed response questions particularly in the end of semester final exam generally contain more predictive power than multiple choice questions or the term test constructed response items.
