the tlf-homework handles just assignments (handing in essays, programming examples, seminar prsentations, etc). We use homework as well in combination with our assesment/self-assessment module, which is not included.
The actual grades are collected in the tlf-gradebook (see screen-cast on the same page). For most of the courses, we are required by law to base the grades of the course not only on a single test, but on several (at least 3) different student evaluations. The need for the tlf-gradebook came from the idea to communicate students their current evaluation.
Needless to say, on the mid-range, we are working on integration of assessment with xowiki to allow agile content develompment and exchange.
