There is, again, no reason why public service cannot be incorporated into individual assessment. Adding value to fire and police services by means of monitoring and reporting (not the piece-work model of something like CrimeStoppers, but actual prevention), supporting environment by counting birds, sampling water, servicing sports events by acting as a timer or umpire - all these can add to a person's assessment.
I'm not thinking of the simple sort of tasks grade school students can perform. Indeed, a person hoping to attain a higher level qualification would need to contribute to the public good in a substantial and tangible way. Offering open online courses (that are well-subscribed and positively reviewed by the community) should be a requirement for any graduate-level recognition. The PhD used to be about offering a unique research contribution to the field; now it's about paying tuition and being exploited as a TA.
These three things - helping others, being cooperative, contributing to the public good - are obviously not easy to assess. To be sure, it's far easier to ask students simple questions and grade the number of correct responses. But assessing students in this way, far from measuring putative 'content knowledge', is really an exercise in counting without any real interest in what is being counted. It acts as an invitation to cheat, as it places self-interest ahead of the values it is actually trying to measure.
