The Scoring of Writing Portfolios: Phase 2

Although most portfolio evaluation currently uses some adaptation of holistic scoring, the problems with scoring portfolios holistically are many, much more than for essays, and the problems are not readily resolvable. Indeed, many aspects of holistic scoring work against the principles behind portfolio assessment. We have from the start needed a scoring methodology that responds to and reflects the nature of portfolios, not merely an adaptation of essay scoring. I here propose a means for scoring portfolios that allows for relatively efficient grading where portfolio scores are needed and where time and money are in short supply. It is derived conceptually from portfolio theory rather than essay-testing theory and supports the key principle behind portfolios, that students should be involved with reflection about and assessment of their own work. It is time for the central role that reflective writing can play in portfolio scoring to be put into practice.
