+Reviewers see the following options:
+
+* **Accept**
+* **Reject** -- When selected, the annotation is rejected and skipped. 
+* **Requeue** -- When selected, the annotation is rejected and then reassigned back to the annotator.  
+
+For example, a reviewer might decide to requeue an annotation that is nearly correct but just needs a slight change. However, an annotation with numerous errors may be easier to simply reject entirely and remove from the queue. 
+
+Note that when you click **Reject**, the annotation is also marked as cancelled/skipped. This is reflected in various metrics (for example, Data Manager columns and dashboards), and differentiates between the two rejection actions in the API with `was_cancelled: true`.

 You can set a low agreement strategy to ensure that a task is not marked complete until it meets 1) the required [overlap](#overlap) and 2) a minimum agreement level.  
 
 * **Do nothing** - Tasks with a low agreement can be marked complete; no additional actions are taken. 
 * **Assign additional annotator** - Automatically assign an additional annotator to tasks with low agreement.
