I am intrigued by this approach to credentialing. To paraphrase Culatta, "been there" doesn't necessarily mean "done that." So, delineating specific activities or accomplishments within a discipline informs the learner of his actual participation, which should lead to more meaningful goal-setting. As a Jawbone/Fitbit wearer, I appreciate tracking my actual progress; I am encouraged to do improve performance. I can see how an adult learner could be motivated by seeing his progress in SIM. Now if only I could resurrect my Girl Scout badges-!
