Q: Is it possible to create a workflow that would track training?

In general, it seems that you can assign a task (ie: go learn something)
And track that the training is completed or not completed.

Perhaps each Training item would or could be a separate Project

But - then there is expiration - ie: Every year you need to go through a refresh.
Example: Every year you need to complete a 1 hour sexual harassment training, managers have to complete a longer 2 hour one.
Example: You need an initial security training, then a yearly repeat or refresh.

I don't think there is a means to create a workflow like that where an assigned task "expires" or re-assigns it self after a while.
