The Peerwork plugin was designed to replicate functionality of WebPA in Moodle allowing a peer weighting to be applied to assignments.
Using this plugin teachers still grade the assignment, but available marks are distributed between students based on peer ratings.

A common complaint from students working on group assignments is that all students receive the same grade regardless of the amount of individual effort / contribution.
The Peerwork plugin was designed address this by allowing teachers to grade work, but for the available marks to be distributed based on peer assessments of students contribution to the assignment. Within this plugin teachers can:
- Set up as many criteria as are needed
- Apply Moodle scales to the criteria (usually Likert)
- Apply privacy settings / visibility of peer scores and comments
- Apply a weighting to the peer element
- Require students to complete peer work
- Report activity completion based on students completion of peer review
- Give students option of leaving feedback comments (can be anonymous)
- Grade assignments (teacher)
- Modify peer weighting by group
- Override final grades where necessary
- Control visibility of peer marks and comments to other students
- Release grades for all students at the same time
- Download csv exports for entire class or individual groups
This plugin was offers an alternative to WebPA natively within Moodle.

Seems trivial, but has bad optics.
You just need to add the scale as documented here:
https://docs.moodle.org/310/en/Scales
Once added, it will be available in Peerwork settings
Are there any known problems with Peer Work when self-evaluation is turned off? My contribution and calculated grades are way off when 'self-grade' is set to No.
Even if all students give each other identical marks (which should in theory result in them having an equal contribution and calculated grade), the results don't reflect this. In the below example, 4 students in total each mark their 3 colleagues, but not themselves. All students marked all other students '3' on every scale / criteria. The same problem also happens if the scoring is done randomly.
Name Contribution Calculated grade Penalty Final weighted grade Revised grade
Test Student 1 0.0000 0.00 0% 30.00
Test Student 2 0.4444 26.67 0% 43.33
Test Student 3 1.1111 66.67 0% 63.33
Test Student 4 2.4444 100.00 0% 100.00
Total 193.33 236.67
When the same test is run with self-grading turned on, and with all students awarding '3' on every scale / criteria for all other students, including themselves, the problem does not occur.

Issue #58 referred to above has been fixed in v2.3.0 However, this will result in a change to grades for existing Peerwork activities with self grading turned off. The change will not automatically filter to the gradebook. The gradebook is updated when the Peerwork grading page is saved.
Thank you User:Sam Cole for highlighting the bug. I have added tests to cover self grading options.
We also found a display issue when the grading scale exceeds the available window space (eg. an 8 point likert) the radio buttons wrap but the scale headings do not which has the potential for students to select the wrong value.
