In the field of initial teacher training, portfolios are widely used to assess pre-service teachers' performance as well as the outcomes of university-based teacher preparation programmes. However, little is known about the explicit design of portfolio assessment mechanisms in teacher preparation programmes. Issues related to the design and validation of portfolios for pre-service teacher assessment are a critical area of inquiry for the field of initial teacher training. In this study, perspectives were elicited from school trainee teachers and faculty from a secondary teacher preparation programme to examine the relationships identified among core competencies of a portfolio assessment framework and pre-service candidate learning outcomes. Comparative findings are presented about the relationships identified by the trainee teachers and faculty across the secondary education programme's portfolio core competencies and trainee learning outcomes. A discussion of the findings is presented with implications and future directions highlighted. (Contains 2 tables.)
