In which status must a standard checklist be for an administrator to edit the checklist due date?

To edit the due date of a standard checklist, it must be in the "Queued" status. When a checklist is queued, it signifies that it is in a state awaiting further action before it can move to the next stage. This status typically allows administrators the flexibility to make necessary adjustments, such as editing the due date, in preparation for when the checklist is actively used.

In contrast, other statuses such as "Completed," "Draft," and "Not Started" come with their own restrictions. A completed checklist is finalized and cannot be modified, while a draft checklist is in a preparatory state and may require finalization before it can have its due date altered. Similarly, a checklist that is not started is typically in a planning phase where specific edit options may be limited, including changes to the due date. Therefore, "Queued" is the appropriate status that allows for the necessary editorial work on the checklist due date.
