 +====== Peer assessment ======

 +===== Goal =====
 +
 +Peer assessment is intended to gather information about the inner workings of the groups, including the impact of the work of each member on the results achieved by the group.
 +
 +==== Procedure ====
 +
 +After logging in using the pair "​user/​password"​ received by email, the student fills out a form tailored to his group, taking into account that:
 +   * For each member of the group, including himself, he chooses the percentage that best represents the impact of the member'​s work in the group work: ideas, commitment, achievements.
 +   * The percentage is stated as an integer and the sum of the percentages must be 100.
 +   * A justification,​ with a maximum of 3 lines of text, may be filled in.
 +
 +The submissions are recorded, but only the last submitted peer assessment will be considered.
 +
 +Peer assessment is confidential and will be used to help a better distribution of the group'​s grade by their elements (as deltas) and to identify possible individual interview needs.
 +
 +The final grade of the group will not be published until all peer assessments of its members are received.
 +
 +==== Example of deltas ====
 +
 +The mean relative deviation of the percentages for each student is used following a logarithmic formula which tends to a maximum delta of 10% (2 out of 20). 
 +Negative deviations correspond to negative deltas.
 +
 +The following table presents the deltas for a group of 4 students; for example, for an assessment of 27%, there is a 8% relative deviation (the difference between the peer assessment (27%) and the expected percentage (25%) divided by the expected percentage (25%)), which results in a delta of 4% (0.8 out of 20).
