The document discusses a project at the University of Warwick to co-create an assessment matrix for e-portfolios with students. Students created digital posters about technology tools and helped design the assessment criteria. The matrix included criteria for digital skills like design, layout, and use of authentic materials. Students provided feedback that participating in designing the criteria and peer assessing helped them understand the assessment process better. While the project enhanced students' digital skills, fully involving students in assessment design was time-consuming. The document raises questions about how much students want to be partners in assessment and how digital skills can be properly accounted for alongside traditional criteria.
