Martin mentioned this in the partners meeting recently - but the prototypes for the Competency Based Education feature targeted for Moodle 3.1 are available now. See http://prototype.moodle.net for a list of the sites, and each site has login details listed on the front page. There is draft user documentation available here: https://docs.moodle.org/dev/Competency_Based_Education:Draft_User_Docs which will be a useful starting point.
This is an early prototype - expect many improvements and bug fixes before this feature is released.
If you have feedback about this feature you can reply to this thread, or reply to the thread in the Future Major Features forum here: https://moodle.org/mod/forum/discuss.php?d=316151.
