The User Identifier is unique to the platform from which the LTI launch occurs. A unique identifier must be entered for each test-taker.

This value can be left blank for anonymous test sessions.

In case the review mode is enabled:

If provided, review mode is to run on a latest delivery execution of a specified user, reviewing their responses.
If not provided, the review runs on an anonymous delivery, viewing only questions.

A user widget, similar to the one displayed in the top-right corner of the TAO Portal, can be displayed for the test taker upon the delivery’s launch. This user widget displays the user’s avatar, and can be expanded to display their username and name.
