Your portfolio should be visual and interactive in which you review all deliverables, feedbacks and reflections to determine how these have contributed to your overall development and growth as a designer. In order to create/update your portfolio you carefully select deliverables and enrich them with reflections on your development. You underpin your overall development with links to evidence from your learning activities. The framework for this development is on the one hand the rubrics, and on the other hand your own long-term goals for your individual growth as a designer.
The portfolio communicates your development as a designer and the development of the overall competence of design, appropriate to your history as a designer up to that point.
