# Learners' Curriculum Version(s)

After a course tree is created, learners enrolled in that course will have individual user trees created for them.

At some point you may need to modify a user-tree version so that you can reset a learner to the curriculum tags most relevant to them at a particular time.

* From a course/program's CBME tab, click 'Configure CBME'
* Under 'Actions,' click 'Modify User-Tree Version'
* Select a user
* Tree ID will display the user's existing tree id
* From the Reset Mode option, pick
  * Override user tree(s) with a specific version
  * Build user tree from versionable root
