What could prevent a document in the Active Learning queue from being assigned to an active reviewer? (Select All That Apply)

A document in the Active Learning queue could indeed be prevented from being assigned to an active reviewer if it has already been coded. In Active Learning processes, documents that have been previous evaluated or coded are typically not reassigned for further review since the goal is to ensure that only documents needing attention or additional review are processed. By excluding already coded documents, the workflow remains efficient and focused on items that require further analysis.

In this scenario, other factors like a document being assigned to a logged-off user or belonging to another user can affect the availability of the document for assignment, but these factors may not typically prevent its assignment in the same way that an already coded document directly does. Additionally, if a reviewer does not have sufficient permissions, they would not be able to review any documents regardless of their status within the queue. However, the primary and most straightforward reason listed, regarding already coded documents, directly aligns with how workflow management is structured to optimize the review process.
