When a teacher is not available to reset an assessment to allow a student complete an incomplete assessment, the students lose the ability to work on the assignment. This occurred during a substituted class, where the teacher was out and created an assessment for the students to complete while he was gone.

When the students get dropped off our network, or something goes wrong, the students get an incomplete and aren't able to finish their assessments.

There should be a setting for setting the level of security. If it is a high stakes assessment where the teacher is available, then protect against these incompletes. But if the assignment is a homework assignment or a sub assignment where the teacher won't be available, allow the system to complete an incomplete assignment without requiring teacher intervention.
