Hello @KatrinaBitz
Are the teachers enrolled in their training portal as 'students?' If so, you should be able to use pathways to track their progress. These guides should be helpful:

If they're not enrolled as students in their training courses, you could consider changing their enrollment status. However, usually for training courses they should be enrolled as students so they can submit assignments and progress through modules in order, etc. If that isn't going to work, you could always run admin reports for grades and course progress. Hopefully this helps!
