I like this thought Julia - perhaps the ONLY way to evaluate informal learning - the prior learning assessment portfolio.
It could be organized specifically for the outcomes and the activities done to achieve those outcomes. I suppose there is an element of trust here. I have confidence that a 'professional' person would give an honest description of the learning they did towards an outcome - I'm less certain about some of our postsecondary students willingness or ability to assess themselves honestly.
I suppose PLA requires a certain level of development - though I guess it could be a mix of items, some of which may have been evaluated by someone else.
But thanks for the approach - this may help me in the future - expand the mind a bit!
