Any idea what I could have done wrong?
Sounds like I must have missed this step. How do I assign achievements? Is there some kind of "assign to all" button?
This is a class of 250, so if I have to do it one at a time I might reconsider.
I turned achievements on before the term began, and account creation is via LTI.
You do have to assign them to the students. They are like problem sets in that way. Unlike problem sets, they are not automatically assigned to students when they are enrolled through LTI. But in the Achievement Editor you can click something that will assign all achievements to all (currently enrolled) students.
