Each submitted session is reviewed by a KTA+ mentor against a public observation rubric. The mentor writes back inside a feedback thread, marks the criteria that were met, and names the criteria that need another attempt.
You resubmit. The thread stays open. The credential is not a test you pass once, it is a record of the loop between what you did in class, what a more experienced educator saw, and what you did next.
Self-paced courses cannot do this. The mentored loop is the argument.
