|The adequacy of evidence depends on which competency you'd like to assess. If you want to assess the competency "Basal Mathematical Knowledge" for example you could create the evidences "can handle numbers between 0 and 1000", "can handle the basic arithmetic operations" and "reads books about mathematics in her free time". This must not be a proof but could be a clue for having that competency.|
An evidence for the competency "Skills in Upper Managemant" could be "was a manager for five years" etc.
So every item or artefact, that seems to be an evidence for the competency, that shall be shown by the presentational ePortfolio, can be part (and should be part) of it.
