 If you have a sort of flexibly paced or open self-paced kind of learning experience and there's assessment, right, you get credit by exam, basically, right? If you have sort of a flexible pace and something that is focused on the doing rather than what's sometimes called simply knowing, which is kind of funny. And then you get maybe something like self-enrichment or a continuing ed kind of class that doesn't have an assessment. And if you get the doing, focus, and assessment, you get performance assessment, right? So you can imagine something like a phlebotomy assessment, which could be time-bound, but nonetheless is focusing on performance. And then when you get all three of them, you get the gold star, namely CBE.
