# Batches

The smallest unit of work that can be assigned to a user.

Batches can be assigned an annotator as well as a reviewer.

An annotator can label images, create issues and ask for a review. He cannot submit a review or mark the batch as finished. Asking for a review moves the batch into validation mode.

A reviewer can submit a review and mark the batch as finished. This moves the batch to completed mode.

A batch can be in four modes

1. **Annotation** - Every batch starts in this mode. And stays in this mode until images are being labeled
2. **Validation** - A batch moves into this mode, when it is submitting for a review. When an annotator has finished labeling images in a batch, he can submit it for a Quality Check.
3. **Quality Check** - The final Quality check for the batch. Once complete, the QC can submit a review with ratings for the annotations.
4. **Completed** - When a reviewer marks the batch as completed, it moves to Completed mode.

**Visilibity** — Batches can be viewed by Admins, Project Managers assigned to parent projects and annotators assigned as an Annotator or a Reviewer to the batch.
