Trina: Isn't the statement "isn't currently supported" a bit incorrect?
It may not yet be hard-baked into quiz items, interactions, or completion triggers that ship with Articulate tools (because let's face it- the standard is very new and coding this in right takes time).
However, it is entirely possible that these CMI codes can be added to any screen, button, etc.
For example, When a quiz is finished, you can have the results page send a CMI JS code for finished, and evaluate scores to determine if usersscore>passscore send Passed/Satisfied or if not, send failed.
I think we understand that when a new spec comes out, it takes time for the software provider to update the tools, but I think it is a bit underselling the potential to send CMI data to an LRS with your tools, because you do provide options to accomplish this.
