Dynamically choose next Test item via extension (adaptive testing)?
Based on test taker answers, I want to select the next test item at runtime for the tester based on the previous answer. Does the extension API support this and if so what "event" can I connect to do make the Item selection? I'm new to the Tao platform.

Hi there,
That's a very good question; we are actually working on an API definition for CAT (Computer Adaptive Testing) within IMS, as a best practice within QTI. This specification allows integration with an external item selection algorithm, basically treated as a black-box.
If you're an IMS member, you can access the draft specification here:
https://www.imsglobal.org/forums/aqti/computer-adaptive-testing-cat
If not, you'll probably have to wait until February 2018 for the first public draft.
Alternatively, you could already use existing QTI preconditions and branch-rules for staged adaptive like testing. Samples for that can be found here:

Thanks,
Mark.
Thank you Mark!
Hi Mark,
Do you know whether there is already a public draft available of this API definition for CAT?
Thanks,
Mark
Hi Mark,
Unfortunately, the process got delayed a bit, so the public draft will now be released after the IMS Learning Impact conference in May 2018.
Again, if you're an IMS member, you can access the internal draft documentation and Swagger API on the IMS GitHub: https://github.com/IMSGlobal/QTI-SPEC-ComputerAdaptiveTesting/tree/master/docs
Access can be requested here: https://www.imsglobal.org/github-access-request
Thanks,
Mark.
Is Adaptive assessment/ branching questions possible on TAO (Community version)?
Have been unable to figure it out.
