I am quite familiar with them and do appreciate their efforts. I think self-evaluation is an excellent component, but limited. Much of the Teachers Going Gradeless movement also relies on self-evaluation to good effect. I think it’s excellent for process and progress, especially as it takes away a lot of the punitive sense that so much assessment uses to motivate and even measure. Still, I don’t know that we can entirely eliminate the need for some kind of external attempt at assessment; it’s just that standardized exams, as they are used as some kind of wide-scale generalized attempt to measure a student’s skill set, cannot accurately do that without the context they try to eliminate. And if you are going to add context, then suddenly the exam gets incredibly specific (which is a good thing).
