When the workshop activity is in the grading evaluation phase, choose the evaluation method "Participation credit". Then select the required evaluation mode and click "Re-calculate grades".

There are three modes of how grades for assessment are calculated by this method.

• All or nothing - The reviewer must assess all allocated submissions in order to obtain the maximum grade; otherwise they receive a grade of zero.
• Proportional - The grade obtained is proportional to the number of assessments. If all allocated submissions are assessed, the reviewer will obtain the maximum grade; if half of the allocated submissions are assessed, the reviewer will obtain 50% of the maximum grade.
• At least one - The reviewer must assess at least one allocated submission in order to obtain the maximum grade.
