    <h2>Description</h2>
    <p>
        Submissions to peer assignments.
Caveats: This table contains public submissions, draft submissions, and deleted submissions. Use the peer_submission_is_draft and peer_submission_has_been_removed_from_public columns to disambiguate
    </p>

    <h2> Columns </h2>
    <table>
        <tr><th>Name</th><th>Description</th></tr>

        <tr>
          <td>peer_submission_id</td><td>Peer submission id</td>

        <tr>
          <td>peer_submission_created_ts</td><td>The time that this submission was created. The submission itself never changes after creation, but some columns affected by things outside the submission may change after creation: (i) `peer_submission_removed_from_public_ts` changes from NULL to non-NULL if/when the author removes the submission from the public (ii) `peer_submission_score_available_ts` and `peer_submission_score` change from NULL to non-NULL if/when the submission receives a score</td>
        </tr>

        <tr>
          <td>peer_submission_is_draft</td><td>Whether this submission is a draft. Drafts are not visible to anyone except the author</td>

        <tr>
          <td>peer_submission_title</td><td>The &quot;title&quot; field of the submission</td>

        <tr>
          <td>peer_submission_removed_from_public_ts</td><td>When this submission was removed from the public review area. This is NULL for public submissions that haven&#x27;t been removed. This is also NULL for drafts because they were never in the public review area</td>
        </tr>

        <tr>
          <td>peer_submission_score_available_ts</td><td>The first time at which the score for this submission was available. This is NULL for submissions without scores and for assignments that don&#x27;t generate scores. Note currently (2016-01) there is a lag between a submission get all reviews needed and peer_submission_score_available_ts. And for learners who submit by review deadline, they willl get be graded even if not meeting N-review requirement, as long as at least being reviewed once(under which scenario, this timestamp will be past review deadline).</td>
