Hi John,

Good question! Most of the courses in the Totara Learn certification are the same between versions 14 and 15 (because those features didn't change in the T15 release) so if you enrol in the Totara Learn Site Administrator program for version 15 you will see that you are already marked as complete for most of the courses (through completing them as part of the T14 program). 

There will be two courses in the program that you do need to complete - the course on Totara Mobile app (which showcases the new Find learning catalogue in the app released alongside T15) and a brand new course on the Content marketplace (which includes the new integration with LinkedIn Learning in T15). If you complete those two courses, you will be awarded your certification. 

I hope that helps - do let us know if you have any further questions.

Rachel
