Thus portfolios can provide evaluation data that is authentic and related specifically to instructional and learning goals. Furthermore, if the data provided through a portfolio approach is specifically related to instructional and learning goals, it will be data that can be used to evaluate the effectiveness of instruction and to determine what has been learned and what still needs to be achieved.
