We incorporate feedback loops called virtuous cycles in everything we do. And I mean everything. Our governance structure is fundamentally iterative. (We're a Sociocracy.) Our project management approach is iterative. (We use Scrum.) We develop ideas iteratively. (We use Design Thinking.) We build our learning tools iteratively. (We use developmental maieutics.) And our learning model is iterative. (We use the virtuous cycle of learning.) One important reason for using all of these iterative processes is that we want every activity in our organization to reward learning. Conveniently, all of the virtuous cycles we iterate through do double duty as virtuous cycles of learning.
All of this virtuous cycling has an interesting (and unprecedented) side effect. The score you receive on one of our assessments is subject to change. Yes, because we learn from every single assessment taken in our system, what we learn could cause your score on any assessment you take here to change. Now, it's unlikley to change very much, probably not enough to affect the feedback you receive, but the fact that scores change from time to time can really shake people up. Some people might even think we've lost the plot!
But there is method in our madness. Allowing your score to fluctuate a bit as our knowledge base grows is our way of reminding everyone that there's uncertainty in any test score, and ourselves that there's always more to learn about how learning works.
