The overall grade is composed of the grade from your peers and extra points (for writing high-quality reviews and for accurate self-evaluation).

Computing grades step-by-step

1. Grade from your peers
Your peers grade your submission based on criteria defined by the instructor. The median score for each criterion is summed up to determine the peer grade. The median is used to avoid outliers (unusual high and low grades). Example:

Assessment criteria
(rubrics)
Grades from peers Median Total
  Max. points Peer 1 Peer 2 Peer 3 Peer 4 Peer 5 All peers (sum of
medians)
Criterion A 2 2 2 2 2 2 2


21 points
Criterion B 2 0 2 2 2 2 2
Criterion C 7 3 5 5 5 7 5
Criterion D 7 3 5 7 7 - 6 (1)
Criterion E 7 - 5 7 - - 6 (2)
(1) In case there is an even number of grades: The average of the middle pair is the median.
(2) In case there are only two grades: The average of the two grades is the median.

2. Extra points for reviews you wrote
Your peers rate the quality of your written feedback by awarding you stars. You will receive bonus points based on their rating. Example:

3. Extra points for accurate self-evaluation
Some peer assessments include an Evaluate yourself phase. If the difference between the score from your peers and your self-evaluation is less than 10% of the maximum points available for the peer assessment, you will receive bonus points (5% of the maximum points). Example:
